Ten U.S. Trade Show Cities and the Venues Behind Them

At the Kentucky Exposition Center in Louisville, the Utility Expo attaches one sentence to every booth type it defines: there is no height limit for product and/or machinery. In the same building, the Mid-America Trucking Show names product and fixture inside every limit it sets and grants no exemption anywhere, which puts a display truck under a 16-foot island cap. Same hall, same industry, opposite answers to the question their exhibitors ask first.

That is the layer most exhibitors miss. The floor load and the ceiling are facts about the building. The permitted booth height is somebody’s rule, set by the venue or by the show, and where both exist the lower one binds. In these ten markets, only two of the fourteen buildings set a booth height of their own. The show sets it, the show changes it between editions, and shows that share a hall often disagree.

You may have the show booked, or you may still be weighing two or three markets against each other. Either way, every city below carries the same four things: exhibit space and ceiling height, permitted booth height and who sets it, the shows that return there and what each one allows, and the hotel and airport access an attendee will use. The figures were read in October and November 2026 from the venues’ own specifications and the shows’ own display rules, and every note below about what an organizer’s own site publishes describes it as it stood in early November 2026. The six largest U.S. trade show markets are covered in a separate guide.

The ten markets at a glance

Where a venue sets a permitted height, the figure below is the venue’s. Everywhere else it is the show’s. Floor load is the building’s own published figure everywhere but Houston, where it reaches you through a show document, and five of these fourteen buildings publish none at all, routing the question to an event manager instead.

Market	Main venue	Published exhibit space	Published ceiling	Maximum permitted booth height	Floor load

Hotels and airport access:

Market	Hotel rooms	Airport access
Indianapolis	4,700 rooms connected by skywalk across twelve or more hotels, in the venue’s own words. The venue gives downtown as both 7,100 and 8,500 rooms	Indianapolis International, fifteen minutes in the venue’s words, with no mileage and no statement of what the fifteen minutes measures. The airport names one non-express bus
Louisville	No hotel is connected to the Kentucky Exposition Center. The 588-room Crowne Plaza is adjacent, in a cluster of more than 5,000 rooms near the airport, and 23,442 metro-wide	Louisville Muhammad Ali International, approximately one mile, measured to the venue by the venue. The destination’s seven miles from the airport is measured to downtown
Houston	Two hotels connect to the George R. Brown by skybridge, the larger with 1,200 rooms, and the venue counts 7,000 reached by its walkways against 100,000 citywide	Bush Intercontinental about 20 miles and Hobby about 10, in the venue’s words, neither saying to the venue or to downtown. A non-stop METRO bus runs from Terminal E
San Antonio	–	San Antonio International, eight miles from downtown and measured to downtown in those words. VIA Route 5 reaches downtown in about 30 minutes for 1.30 dollars
New Orleans	More than 7,300 rooms within a five-minute walk, one of the few figures here that states its own radius, and 26,000 within two miles. None is connected	Louis Armstrong New Orleans International. No source publishes a distance. The transit authority’s Airport Express, route 202, runs to two downtown stops for 1.25 dollars
Washington DC	The Marriott Marquis is connected by tunnel, 1,175 rooms on its developer’s figure, with 7,700 within walking distance. The Gaylord is itself the venue, at 1,996	The venue sits atop its own Metro station on the Green and Yellow lines. Three airports serve the market and the operator gives a distance to none. The Gaylord gives 6.9 miles to Reagan National
Minneapolis and Saint Paul	The Hyatt Regency’s 644 rooms and the Hilton connect to the Minneapolis center by skyway. In Saint Paul the 410-room InterContinental connects to the RiverCentre	Minneapolis-Saint Paul International, 12 miles and measured to downtown. The Blue Line reaches downtown in 25 minutes for 2.00 dollars but does not reach the convention center
Philadelphia	The venue names and counts both its connected hotels, the 1,408-room Marriott Downtown and the 179-room Aloft. Its own page gives the room counts as 14,000 and 10,000	Philadelphia International, with no distance published anywhere. The SEPTA Airport Line runs every 30 minutes to Jefferson Station, which the connected Marriott links to
Detroit	None is connected. The 100-room Foundation Hotel is across the street, and the destination gives the Renaissance Center Marriott as both 1,298 and 1,323 rooms	Detroit Metropolitan Wayne County, and neither the venue nor the airport publishes a distance. A People Mover station sits inside the building, on the fourth floor
Phoenix	–	Phoenix Sky Harbor, the only market here needing a transfer: the free Sky Train to 44th Street, then Valley Metro Rail for 2.00 dollars. No station is named for the convention center

Read that table with three cautions in mind, because this is where comparisons between markets go wrong.

Rooms connected, rooms within walking distance and rooms citywide are three different counts, and a source will often quote one without naming which. Philadelphia gives a connected figure and names its hotels, while Indianapolis gives the figure and a hotel count without the names. New Orleans gives a five-minute walk and is one of the few publishers anywhere that states its own radius. Louisville and Detroit have no connected hotel at all, and both put their nearest hotel across a road. Read the scope before you compare two markets.

Airport mileage is measured to the venue in Louisville and at the Gaylord National, and to downtown in San Antonio and Minneapolis. Those are not comparable numbers. Louisville shows why inside one city: the Kentucky Exposition Center sits about a mile from the airport and says so, while the destination advertises seven miles from the airport because it is measuring downtown. Both are correct. Neither is a conflict. The building and the city center are simply not in the same place.

Two of these markets are under construction through the life of this guide. Louisville takes delivery of a new 350,000 square foot facility at the Kentucky Exposition Center on December 31, 2026, then starts a 213 million dollar redevelopment of the West Wing, West Hall and Pavilion. The agency says that work will take 18 to 24 months and has announced no completion date. Its airport is rebuilding two concourses into the fall of 2027. In Houston, the convention district program runs to 2038, a 700,000 square foot south building is due in May 2028, and the Avenida South garage is coming down now. Exhibiting in either city in 2027 means confirming hall, dock and gate status in writing before you book a move-in.

What this guide covers

Also in this guide: The ten markets at a glance · What to do with all this · Frequently asked questions

Indianapolis

Indianapolis is a two-building market, and an enclosed pedestrian corridor joins the two buildings, which makes it easy to treat them as one. The floor says otherwise. The Indiana Convention Center is rated at 500 pounds per square foot across most of its halls and 350 in Halls D and E. Lucas Oil Stadium, at the other end of that corridor, is rated at 800. That is the highest figure any building in this guide publishes for itself, a short walk from one of the lowest.

Venue	Exhibit space	Ceiling height	Maximum permitted booth height	Floor load
Indiana Convention Center	Eleven halls, 566,600 sq ft contiguous	35 ft in all halls	Set by the show	500 lb/sq ft in Halls A to C and F to K, 350 in Halls D and E
Lucas Oil Stadium	Two exhibit halls, 44,000 sq ft in the venue’s facility guide, where Hall 1 is 25,800 and Hall 2 is 18,200, against 43,000 on the venue’s own web page	26 ft	Set by the show	800 lb/sq ft

The stadium is not a footnote here. Four of the city’s seven recurring shows name it, three of them for exhibits. The PRI Show runs a space inside it called the Lucas Oil Exhibit Hall and runs its own move-out from there. FDIC International lists it as one of five named exhibit areas on its floor plan menu, with its own hours. Gen Con names it as a venue alongside the convention center. The ceiling is the trade-off: 26 feet in the stadium halls against 35 in the convention center.

The ceiling figure needs checking, because a show contradicts the building in writing. The convention center publishes 35-foot ceilings in all halls. Work Truck Week prints, three times in its own rules, that due to uneven ceiling heights within the Indiana Convention Center, exhibit heights allowed by trade show management may not be available in all areas. The PRI Show’s floor plan prints the numbers: 15 feet for booths 6000 to 6159, 24 feet for booths 9400 to 9527, a 20-foot ceiling note, and an outline marked low ceiling. The venue’s 35 feet is the structural dimension. The show figures are what you get at a specific booth number.

Hanging sign rules by show:

Show	Hanging sign
Work Truck Week	Island and split island only, not standard or corner Maximum 25 ft and minimum 14 ft off the ground, with the measurement point unstated Applies to ceiling-supported structures, fixtures, LED walls and signs, and not to truss or lighting, which is pre-approved separately Approval by February 5, 2027
PRI Show	Printed under the show’s peninsula heading, with no sentence extending it to another booth type 24 ft from the floor to the top of the sign, with the sign itself not exceeding 8 ft, set back at least 10 ft from the back line and limited to 50 percent of the corresponding booth dimension Balloons and helium devices are banned
Gen Con	Island or peninsula of 20 by 20 or larger only At least 12 ft from the floor to the bottom of the banner and no higher than 22 ft to the top, which fixes the banner’s own height at 10 ft Both measurement points are stated, which is rare
FDIC International	–
National FFA Convention & Expo	–

WWETT Show	–

Work Truck Week caps a standard booth at 12 feet. The PRI Show caps a linear booth at 10. Gen Con ignores booth type and caps by footprint, 12 feet under 20 by 20 and 22 feet above it. A standard booth that passes at one of them is over height at another.

The hanging sign rules use three different measurement conventions. Work Truck Week gives a 25-foot maximum and a 14-foot minimum, and never says which end of the sign the 25 feet refers to. The PRI Show measures to the top of the sign and says so, then caps the sign body at 8 feet. Gen Con states both ends, 12 feet to the bottom and 22 to the top, which fixes the banner at 10 feet. Carry one show’s sign to another show’s floor here and you will be rerigging it.

Four of the seven keep their display rules somewhere other than their website. FDIC International lists its order form titles without the files behind them. The FFA convention’s terms document returns a server error. The Sweets & Snacks Expo emails its manual to registered exhibitors. The WWETT Show splits its policies across separate pages. Write to all four for the current rules and the edition year before you design.

Working in Indianapolis

The 800 pounds per square foot in Lucas Oil Stadium is the number to plan around if you are bringing weight. It is more than double the convention center’s lighter halls and the highest figure any building in this guide publishes for itself. The cost is overhead and floor area: 26 feet against 35, and 44,000 square feet against 566,600.

Approval deadlines here belong to the shows, not the venue, and they fall early. Work Truck Week wants hanging sign approval by February 5, 2027, for a show that opens March 10. Gen Con wants plans by June 1 for anything over 8 feet, for a show that opens August 5. Both sit about a quarter ahead of the doors.

The uneven ceiling warning has one practical answer. If your property is taller than about 20 feet, get your booth number first, then ask the show in writing for the clear height at that number before the design goes to production. One show in this building publishes figures lower than the venue’s 35 feet and another prints a warning without numbers, and neither maps where the low areas are.

Louisville

Louisville is one building and one rule that splits in half. The Kentucky Exposition Center hosts four recurring shows, two of them major machinery shows, and the two take opposite positions on whether a machine counts as a booth.

Venue	Exhibit space	Ceiling height	Maximum permitted booth height	Floor load
Kentucky Exposition Center	North Wing 218,286 sq ft, South Wing A to C 421,200, West Wing 175,715, Pavilion 75,344, marked gross on the venue’s own building diagrams	27 ft in all three South Wing halls, 15 to 28 ft in the North Wing, 15 to 16 ft in the West Wing	Set by the show	–

The floor load is the first thing to ask about and the venue does not publish it. Its own facility brochure prints a line directing the reader to contact the center for details in the columns where a capacity figure would sit, and its website sends weight questions to the event manager. Five of the fourteen buildings in this guide handle the floor load that way. Louisville is one of them, so budget a phone call before you budget steel.

The ceiling varies more inside this building than the single figure suggests. All three South Wing halls run 27 feet. The North Wing runs 15 to 28 feet depending on the section, and the West Wing runs 15 to 16. A property designed for the South Wing will not stand in the West Wing.

Shows in Louisville

Show	Venue and halls	Cadence	Previous edition	Next edition

Booth rules by show:

Show	Booth types and maximum height
National Farm Machinery Show	Standard, meaning booths in a straight line no deeper than 10 ft, 8 ft across the back wall and rear half and 4 ft across the front half End cap and peninsula take a back drape set 4 ft inside on both sides for the aisle sight line Island and split island carry no figure, since height follows the ceiling or beam at the space, and anything over 8 ft needs prior approval Two-story exhibits, canopies, tents and overhead awnings are banned
The Utility Expo	Standard, meaning a depth under 20 ft, covering in-line, perimeter, corner and peninsula layouts at that depth, 10 ft or 3 m Corner and perimeter at 20 ft deep and 400 sq ft or more, 15 ft or 4.5 m Peninsula and island, 20 ft or 6 m, with no minimum size stated for an island All five carry the same clause: there is no height limit for product or machinery Towers take the height of the configuration they belong to, and a tower over 12 ft needs drawings with a structural engineer’s stamp Standard depth carries a 5 ft setback for solid material above 4 ft, and all machinery sits 6 inches back from every aisle The figures are from the 2025 rules, and the organizer has since posted a 2027 edition
Mid-America Trucking Show	Linear 8 ft for any sign, display, product, fixture or decoration Perimeter 12 ft on the same wording Peninsula, meaning four or more 10 by 10 spaces back to back with aisles on three sides, 16 ft Split island 16 ft Island, aisles on four sides and at least 400 sq ft, 16 ft There is no product or machinery exemption anywhere: every height clause names product and fixture inside the limit Display vehicles are handled by setback instead, 10 inches back from the aisle, no more than 80 percent of the contracted space, and conforming to line of sight Space is measured from the centerline of the side rails Line of sight caps anything at 4 ft within 5 ft of an aisle and 10 ft of a neighbor A canopy base sits no lower than 7 ft within 5 ft of an aisle, with signs and products under it to 8 ft 3 in

The Utility Expo	Banned in standard exhibits Permitted for corner, perimeter, peninsula and island at unlimited height, with no measurement point stated Corner and perimeter signs hang at least 5 ft from neighbors on all sides, a peninsula sign at least 5 ft from the back of the booth, and an island sign may sit on the booth line Outdoors a 100 ft limit applies, which the document attributes to the airport beside the venue
Mid-America Trucking Show	Banned on linear exhibits Permitted on perimeter to 12 ft from the floor to the top of the sign, flat and two dimensional, set back at least 5 ft from the aisle, with no minimum booth size Permitted on peninsula, split island and island at any height, with the sign itself no more than 8 ft tall and finished on all sides Signs facing a neighboring exhibit sit at least 10 ft from it Scaled engineering drawings are due at least 60 days before the first show day
Equip Exposition	–

The machinery exemption is the whole story in this market. The Utility Expo attaches the same clause to all five booth types it defines: there is no height limit for product or machinery. A crane or an aerial platform is exempt from the cap, and the show asks only for a floor plan showing the height of booms and jibs. The Mid-America Trucking Show grants nothing. Its height clauses name product and fixture inside the limit, which caps a display truck in an island booth at 16 feet, and it handles vehicles by setback instead: 10 inches off the aisle, no more than 80 percent of the space.

Sixteen feet is also low for an island. The Utility Expo allows 20 feet in the same hall, and the equipment shows in Indianapolis and New Orleans allow 20 or more. If you are bringing a truck to Louisville in March, confirm that figure with show management before you commit to a design.

The hanging sign rules split the same way. The Utility Expo bans signs in standard exhibits and then allows an unlimited hanging height for the other four types, with the only cap outdoors, where a 100-foot limit applies because the airport sits next door. The Mid-America Trucking Show bans signs on linear booths and allows a perimeter booth 12 feet measured to the top of the sign, one of only three perimeter sign permissions in this guide.

The National Farm Machinery Show is stricter than both and in a different direction. Standard booths get 8 feet at the back and 4 feet at the front. Islands get no figure at all, because the show ties island height to the ceiling or the beam above the specific space. Two-story exhibits are banned outright, and so are canopies, tents and overhead awnings, in any manner, for the duration of the show.

Equip Exposition keeps its display rules behind an exhibitor dashboard. Its public pages carry an application, a booth map and a help center, and none of them links a rules document. Ask the organizer directly.

Working in Louisville

Two deadlines in this market do not agree, and the gap is a month. The Mid-America Trucking Show wants multi-level drawings 60 days before the first show day, which computes to January 17, 2027. The venue’s own facility regulations require multi-level approval 90 days in advance, which computes to December 18, 2026. Neither party prints a calendar date. Plan to the earlier one.

Rigging weights come from the venue and one show quotes them back: 3,000 pounds on the major trusses, 1,500 on the bar joints, and 500 pounds at a single point with three points possible, from structural steel only. Hanging from sprinkler, water, gas, air or HVAC lines is prohibited.

And the construction schedule matters more here than anywhere else in this guide. The state agency that runs the center takes delivery of a new 350,000 square foot facility on December 31, 2026, and says it will have major events in the space during 2027. The next phase is a 213 million dollar redevelopment of the West Wing, West Hall and Pavilion, which the agency says will take 18 to 24 months and for which it has announced no completion date. If your 2027 show sits in the West Wing or the Pavilion, confirm the hall in writing before you plan anything else.

Houston

Houston is two campuses that do not mix. The George R. Brown Convention Center sits downtown. The Reliant Center sits on the Reliant Park campus several miles away. Five of the city’s eight recurring shows use the convention center and three use the campus, and a figure from one says nothing about the other.

Venue	Exhibit space	Ceiling height	Maximum permitted booth height	Floor load
George R. Brown Convention Center	Level 1 Halls A to E 547,730 useable sq ft, Level 3 Halls A3 and B3 205,440	35 ft on Level 1, 30 ft on Level 3	Set by the show	1,000 lb/sq ft, Halls B to E, carried by a show document
Reliant Center	More than 706,000 sq ft, eleven halls, all contiguous on the ground level	Ranges 25 to 60 ft by band, the venue’s average 30 ft	Island 25 ft, set by the show carrying a venue rule	–

The 1,000 pounds per square foot at the George R. Brown is the highest published figure in this guide, and it reaches you through a show rather than the building. A cardiology meeting prints it in its own rules for Halls B to E. The venue does not publish a floor load of its own, so that document is the source, and you want a copy of it.

The Reliant Center organizes its ceiling by band rather than by hall, which no other building here does. Its ground-level plan marks 30 feet across the north band, a slope to 60 feet through the middle, and 25 feet across the south, with a note on the south band that no rigging is permitted in that area. Eleven halls, three ceiling zones, and the zone matters more than the hall letter.

Shows in Houston

Five of these eight publish a height schedule, and two of the five contradict each other on the same question in the same building.

ACC.27-WCC, American College of Cardiology	In-line displays including signage may not exceed the 8 ft back drape, with 4 ft in the front 5 ft, and an in-line booth 20 ft or wider may extend headers forward of its midpoint if sight lines are not restricted Island 20 ft, with lighting truss to 23 ft and no visible graphics on it The peninsula and end cap are abolished rather than restricted: the show states they will not be assigned A 40 percent see-through effect is required from the floor to 8 ft, walled areas may cover only 40 percent of any given dimension, and a walled meeting room needs an island of 400 sq ft or more Covered exhibit plans due March 9, 2027
Houston Livestock Show and Rodeo	No booth types are defined, and height follows the building rather than the geometry In Reliant Center the back height must be between 8 and 10 ft including signage affixed to the back wall, and a variance needs advance written approval In Reliant Arena the limit is 8 ft and no variance will be approved Over all of it, nothing may extend above 12 ft or into the aisles Rodeo Plaza has a standard space of 25 ft deep by 30 ft wide and no height figure
Houston Auto Show	Types are defined by what is on display rather than by geometry Passenger car and truck exhibits 25 ft Aftermarket and specialty vehicle exhibits 18 ft Aftermarket vendors take a stepped rule instead: 5 ft from the aisle to 5 ft back, then 8 ft to the back of the booth, including any product, display or booth structure There is no height exemption for vehicles; the venue may instead require additional clearances for any display it considers an excessive obstruction Identification signs sit at least 3 ft from neighbors and 18 in from an aisle, turntables and narrator displays at least 10 ft and 6 ft, each aisle side keeps a third of its length clear, and nothing may protrude into the aisle, an opened vehicle door included The figures are from the show’s 2026 manual, and its current exhibitor page posts no manual
Turbomachinery and Pump Symposia	Linear 8 ft in the rear half, 4 ft in the front half Perimeter 12 ft in the rear half, with perimeter defined by booth number rather than wall position, the even numbers in the 100 row and the odd numbers in the last row on the right of the hall, and still 4 ft in the forward 5 ft Island, 20 by 20 or larger, 20 ft throughout, stated as an absolute Extended header, a linear booth 20 ft or longer with a center header, keeps the linear rules except that the header takes 8 ft, a width of 20 percent of the booth’s length and a depth of 9 ft from the back wall A corner booth gets no figure, only a requirement to drape its reverse faces at the exhibitor’s cost For a split island the page carries only the industry association’s wording, a typical maximum height range allowance of 16 to 20 ft including signage
NAPE Summit	–
International Quilt Festival	Two footprints, from the organizer’s 2025 information sheet rather than its current one: a full booth at 10 ft by 10 ft, and a half booth at 10 ft of aisle frontage by 6 ft deep The rental includes one 6 ft or 8 ft table, two chairs, a lettered identification sign and a show program listing No height is given for either The current letter withholds the footprints altogether, saying the booth types sit in a contract packet issued after an application is screened

Hanging sign rules by show:

Show	Hanging sign
Offshore Technology Conference	Banned over linear and perimeter booths Permitted over peninsula, split island and walk-through at 20 by 30, 600 sq ft, or larger, and over an island with no size gate beyond the 20 by 20 definition Maximum 25 ft to the top of the sign, qualified by the show’s own phrase if ceiling height allows, which hands the real limit back to the building Double-sided signs set back 10 ft from the common wall
ACC.27-WCC, American College of Cardiology	Island of 20 by 20 or larger only, and no permission for an in-line booth Maximum 20 ft at the top for signs and banners, with truss to 23 ft The measurement point is stated as at the top, so the sign may not rise above the booth’s own 20 ft cap Due before March 9, 2027 with a dimensioned schematic
Houston Livestock Show and Rodeo	Banned for every booth Signs may not hang from the ceiling or be attached to building walls or columns
Houston Auto Show	Effectively banned, with one discretionary door Hanging signs, banners and pennants on walls or columns are prohibited, no ceiling-hung sign is permitted without prior written approval from the venue, and supporting wires from the ceiling are not permitted
Turbomachinery and Pump Symposia	Island booths only, 20 by 20 and larger, with no suspended sign or banner permitted in any other type Maximum 24 ft from the top of the sign to the floor of the exhibit hall, and the same 24 ft governs a floor-supported sign No setback and no deadline are stated A variance needs a drawing of the sign and its placement, and the organizer calls one unlikely

International Quilt Festival	–
IMAGE, the International Meeting for Applied Geoscience and Energy	–

The two-story question is the one to read. At the George R. Brown, the American College of Cardiology permits a two-story exhibit and prices it at 13.00 dollars per square foot of the entire booth, not of the upper deck. In the same halls, the Turbomachinery and Pump Symposia say in their rules that multi-story exhibits are not allowed and in their own FAQ that double decker stands are not allowed. Same building, same year, and one show sells what the other forbids.

The machinery exemption splits three ways across this guide and Houston holds one of the three positions. The Offshore Technology Conference extends its exemption to physical equipment, excludes the exhibit structure in the same sentence, and keeps the decision at its own discretion. The Utility Expo in Louisville gives an unconditional clause. The Mid-America Trucking Show gives none. If you exhibit machinery in more than one of these cities, you are working to three different rules.

Two shows here set no height by booth type at all and govern by other means. The Houston Livestock Show and Rodeo classifies exhibitors by building and sets height by address: 8 to 10 feet in Reliant Center, a flat 8 feet in Reliant Arena with no variance possible, and a 12-foot ceiling over everything. It also ties one height exception to a specific aisle number where double columns block the view. The Houston Auto Show defines its types by what is on display and then contradicts itself: 18 feet for aftermarket exhibits in the general rule, against 5 and 8 feet for aftermarket vendors on the same page. Settle that one with show management before you print anything.

Three of the eight carry no height at all because their contracts move the question elsewhere. NAPE Summit routes every height to an exhibitor booth display guidelines document that its contract places on the show’s own site, and what the site posts beside the terms is the industry association’s general guidelines file. IMAGE incorporates an exhibitor services manual by name and releases it about 90 days before move-in, which for an August 2027 show lands in roughly May. Both are George R. Brown shows, and in both cases an exhibitor signs before seeing the rules. The quilt festival is the third: its current letter withholds the footprints and says the booth types sit in a contract packet issued after an application is screened.

Working in Houston

Each campus answers for itself, and the mistake to avoid is carrying one answer across. The convention center publishes 35 feet on Level 1 and 30 on Level 3. The Reliant Center publishes three ceiling bands and bans rigging in the southern one. A traveling property that clears the convention center may not clear the south end of the Reliant Center floor, and the plan rather than the hall letter is what tells you.

One figure in the Offshore Technology Conference rules is easy to read as something it is not. It says the live load for the upper level of a multi-level booth should be at least 125 pounds per square foot. That is a design load for your own deck. It is not a Reliant Center floor rating, and the Reliant Center does not publish one.

Vehicle and fuel rules are stricter here than in most of this guide and they are consistent between the shows. Tanks hold no more than a quarter tank or five gallons, whichever is less. Battery cables come off and get taped. The Offshore Technology Conference also wants 72 hours’ notice before a vehicle arrives on site, and ignition keys stay at the display.

San Antonio

San Antonio is the easiest market in this guide to describe and one of the hardest to plan for. One building holds all six recurring shows. The halls are contiguous, the five numbered halls share one ceiling height, and the published record stops almost exactly where an exhibitor’s questions begin.

Venue	Exhibit space	Ceiling height	Maximum permitted booth height	Floor load
Henry B. Gonzalez Convention Center	Five halls, 514,000 sq ft contiguous	35 ft in all five exhibit halls	Set by the show	–

Look closely at three parts of that row. The 514,000 square feet is the venue’s own contiguous figure; the five numbered halls sum to 497,316, and the difference is the Bridge Hall and the space connecting it. The 35-foot ceiling holds across all five numbered halls and is confirmed in two separate venue documents. The Bridge Hall is 24 feet, eleven feet lower, and the venue’s own exhibit halls page counts it as one of the exhibit halls. So the 514,000 and the 35 feet do not describe the same set of rooms. Name the halls when you quote either figure.

The column line is the most useful sentence this building publishes about itself. Its sales brochure advertises 86,878 square feet of column-free space, and 86,878 is Exhibit Hall 1 exactly. By naming one hall the venue tells you, without saying it, that the other four have columns, and it gives no spacing for them. If you are planning a large island in San Antonio, ask for Hall 1 by name.

The floor load column is empty here, and that reflects the city rather than one thin source. The venue’s 25-page operational policy, its room specification sheets and its own sales brochure carry no pounds-per-square-foot figure for an exhibit hall, and none of the six shows carries one either. If you are bringing weight into these halls, get the figure from show management in writing before you commit to the build.

Shows in San Antonio

Houston and Louisville show you two shows disagreeing. San Antonio shows you something harder to work with: six shows in one building, where four of them will not tell you the height at all.

Premiere San Antonio	–

Count how the six divide. One publishes a complete schedule by booth type. One publishes its drape heights and sends every other dimension to a booth descriptions document it links but does not set out. One names four booth types and dimensions none of them. One defines three types, gives none of them a height, and does not publish its own drape heights. One publishes real figures in documents dated January 2025 and June 2018. One publishes nothing we could reach. What you may build at the Henry B. Gonzalez depends almost entirely on which show you are at, and most of those shows will not tell you in advance.

The SOT Annual Meeting and ToxExpo publishes the thinnest height rule here, and its shape is the lesson. The page names Inline, Corner, Island and endcap, defines none of them, and attaches no height to any of them. The only height figure on it is a trigger rather than a limit: an exhibitor with island or endcap space, and anyone adding pipe and drape above eight feet, submits drawings for approval by February 12, 2027. From the published rules you can learn the height at which you must ask permission, not the height you are allowed to build.

At the other end, the Craft Brewers Conference publishes a 12-foot in-line allowance in the rear half of the booth, four feet above the eight that most shows in this guide use. Those three figures sit on the organizer’s own current exhibitor FAQ. The setbacks and the vehicle rule around them come from rules documents dated January 2025 and June 2018, so check the edition before you build to anything but the three.

The multi-story question splits three ways inside one building. IWF West carries a full rule set with a 900-square-foot floor gate and a 50 percent surcharge on the upper level, which is the only complete multi-story rule any show here publishes. SOT does not raise the subject. The Texas Dental Association meeting disposes of it in one sentence requiring compliance with federal law and state and local fire and safety codes, which hands the whole question to the building code. Same halls, three positions, and one of the three gives you something to price.

Hanging signs divide the same way. IWF West writes the clearest sign rule here, and the only one that protects a band of air. Islands, peninsulas and split islands at 600 square feet or more may hang a sign at a minimum of 20 feet at its lowest point, or 16 feet 6 inches at its highest. The space between those two heights stays clear for the show’s own aisle signage. Submission runs at least two months before your assigned freight arrival date. The dental meeting bans hung signs anywhere in the venue without its specific written approval. The toxicology meeting prints two sentences that cannot both be followed, one allowing identification above contracted island space and one prohibiting exhibitors from hanging anything over their space at all, with no minimum size, height or setback attached to either. If you are planning a sign for that show, settle it with show management rather than with the page.

Working in San Antonio

San Antonio regulates a double-decker by area, not by height, and that makes it a different build from Detroit or Philadelphia. The city fire marshal’s requirements for indoor exhibits set thresholds instead of a cap. Smoke detection is required on any level above 120 square feet, two remote exits on an upper level above 300 square feet, and sprinklers on a multi-level booth above 400 square feet per level. The structure itself must be designed and sealed by a Texas registered design professional against the building code’s live-load chapter. No height number comes from the venue or from the city. Detroit publishes 25, 19 and 15 feet. Philadelphia publishes two stories and 30 feet. Carry an assumption from either of those cities into this one and you will be redesigning on site.

The deadlines here run tighter than the regulation does. Construction documents go to the fire marshal no later than 15 days before the event opens, and building is prohibited until formal approval is issued. That is the shortest city deadline here, against 90 days in Louisville and 60 in Detroit. Your show’s own clock is often earlier: IWF West wants a hanging sign submitted two months before your assigned freight arrival date, and the toxicology meeting wants booth drawings by mid-February for a mid-March show. You are bound by whichever date arrives first.

The dock side of this building is well documented and the details cost money. Halls 1 and 2 load through the East dock, Halls 3 and 4 through the West. Everyone entering either dock checks in at the security guard booth to have identification scanned and a wristband issued, and the wristband colors change daily. A privately owned vehicle gets a 20-minute pass. The speed limit inside the docks is five miles per hour. Freight arriving before your first contracted date or after your last is refused. Forklift flags are signed out from venue security at the start of move-in and returned at the end of move-out. The line to budget for: Gate 1, on the East dock by Tower of the Americas Way, is an exit only, and it opens only if the show hires off-duty San Antonio police to staff it.

New Orleans

New Orleans is one building and seven recurring shows, and it is the market in this guide where the venue tells you the most and the shows agree the least. The Ernest N. Morial Convention Center publishes its own floor load twice, in two documents two years apart, with the same figures both times. That makes it the best-evidenced building here on the number most exhibitors ask about last and should ask about first.

Venue	Exhibit space	Ceiling height	Maximum permitted booth height	Floor load
Ernest N. Morial Convention Center	Halls B to J 966,327 sq ft, plus the Great Hall at 60,300, with no gross or net label from the venue	27 ft minimum under serviceways in most halls, 24 to 26 ft in the low-ceiling areas	Set by the show	350 lb/sq ft, with a drawn heavy load area of 89,145 sq ft at 500

Read the floor load twice. The halls are concrete slab at 350 pounds per square foot. Above that, the venue’s own 2026 first-floor map prints a hatched zone with a figure inside it: a heavy load area of 89,145 square feet at 500 pounds per square foot. The zone sits across Halls H and I, bounded on the drawing by freight gates 18 to 21. That zone is larger than Hall J. If you are shipping machinery to New Orleans, ask for space inside it by name, because the difference between 350 and 500 is the difference between rolling a machine on and engineering a load spread for it.

One caution travels with that figure. The venue’s written procedures describe the 500-pound zone as some areas in Halls H through J in one place and as the rear portion of Halls H, I and J in another, while the map draws it over Halls H and I. Quote the venue’s wording and the drawn figure. Do not tell a client that Halls H to J are rated at 500.

The ceiling figures are clearances rather than peaks, and the venue distinguishes them. The 27 feet is a minimum under the serviceways, not the height of the roof, and the low-ceiling areas run 24 to 26 feet. Rigging follows the same split, in two regimes. The peaked-ceiling areas need prior written authorization above 250 pounds per hanging point, and the finished-ceiling areas of Halls E through J are handled by special arrangement, with no limit published. Rigging plans are due 60 days before move-in, and only the venue or the general contractor may rig inside it.

Shows in New Orleans

This is the city for the hanging sign question. Five of these seven have an answer to it, though only three publish a rule, and no two of the answers are the same.

Show	Booth types and maximum height
ASH Annual Meeting and Exposition	Inline, meaning linear 10 by 10 booths: nothing above 4 ft within 5 ft of the front, backgrounds to 8 ft, or 12 ft for a perimeter booth A corner booth gets no figure An island is 400 sq ft, 20 by 20, or larger with aisles on four sides, and no general island height is stated A booth may not be wider than it is deep, at the show’s discretion Multi-level follows the island rules, tops out at 20 ft from the floor, needs a structural engineer’s stamp on construction and occupant load, and is charged at the island rate for the second level Peninsula, end cap, split island and walk-through are not defined
The ARA Show	Standard booths are 10 by 10, 100 sq ft minimum, with a 20 by 20 minimum for islands and peninsulas, and three footprints cannot be accommodated: 30 by 30, 30 by 40 and 40 by 40 Standard in-line 8 ft for display materials Perimeter takes the standard rules except a 12 ft back wall Peninsula 20 ft including signage, for the center portion of the back wall Island 20 ft for fixtures, components and identification signs Fixtures over 4 ft within 10 lineal feet of a neighbor sit at least 5 ft from the aisle line Multi-level needs a certified structural engineer’s stamp and two means of egress from upper levels, with no height given Corner, end cap, split island and walk-through are not defined
World of Asphalt and AGG1	The types are defined by depth rather than by open sides Standard means any exhibit under 20 ft deep, in-line, perimeter, corner or peninsula alike, at 10 ft or 3 m Corner and perimeter at 20 ft deep or more and 400 sq ft or more, 15 ft or 4.5 m Peninsula, open on three sides and sharing a back wall, 20 ft or 6 m Island, with no minimum stated, 20 ft or 6 m Every type carries the same clause: no height limit for product or machinery So a perimeter booth has two caps depending on its depth, 10 ft under 20 ft deep and 15 ft at 20 ft or more A 5 ft setback applies to solid materials above 4 ft and standard drape is 8 ft Multi-level and covered exhibits need stamped scaled plans and fire marshal approval, towers over 15 ft need an engineer’s stamp, and floor plans for 400 sq ft or more are due by December 1, 2026
International WorkBoat Show	The organizer’s own event information page carries line of sight rules rather than a type schedule Nothing in the front half of an in-line or perimeter booth rises above 4 ft Pop-up banners, scroll banners and wind flags sit in the back half, under 8 ft in an in-line booth and 14 ft in a perimeter booth Each 10 by 10 is set with an 8 ft back drape and 3 ft side drapes Multi-level plans must state the maximum number of occupants and carry a structural engineer’s stamp on the occupant load, and the show recommends drawings from every exhibit of 20 by 20 or more No island figure is published
AAO-HNSF Annual Meeting and OTO EXPO	The show sets no height of its own and delegates the whole rule set, crediting the industry association’s guidelines without naming an edition year No booth type carries a figure, and the words peninsula, perimeter and end cap appear nowhere in what it publishes Multi-level gets one sentence, saying exhibitors have the option Carpet is required in every booth and is installed at the exhibitor’s cost if it is missing, and any floor covering over 2 in high needs safety lighting against trips The 8 ft walls quoted for the private meeting suites are a suite specification and not a booth height

Hanging sign rules by show:

Show	Hanging sign
ASH Annual Meeting and Exposition	Island only The top of a sign suspended from the ceiling or attached to the booth must not exceed 20 ft from the hall floor and must not block the show’s own signs or other exhibitors A sign hangs directly over the island and not over an aisle, though the show may allow one to cross an aisle to join another part of the same booth, for a fee on the incorporated aisle space Island renderings due Friday, October 16, 2026
The ARA Show	Island and peninsula only, for signs and lighting truss alike Banned in linear booths Perimeter booths are neither listed as permitted nor expressly banned The suspended height is 20 ft from the floor to the top of the sign A sign is set forward at least 5 ft from the back line of the booth and from the adjacent neighbor, and may not exceed the perimeter of the assigned space No submission deadline is stated
World of Asphalt and AGG1	Permitted in corner, perimeter, peninsula and island, each at unlimited height, and banned in standard exhibits With no maximum and no measurement point, the practical cap is the building Corner and perimeter signs hang 5 ft from neighbors on all sides, a peninsula sign 5 ft from the back of the booth, and an island sign may sit on the booth line All hanging sign assembly and rigging is arranged through the venue

Set the five answers side by side. World of Asphalt permits signs at unlimited height in four of its five booth types, which makes the building the only practical cap. The ARA Show allows 20 feet to the top of the sign in islands and peninsulas and bans them in linear booths. The hematology meeting allows 20 feet to the top in islands only, and will let a sign cross an aisle to join another part of the same exhibit for a fee on the aisle space it takes. The otolaryngology meeting does not raise the subject anywhere in what it publishes. The ESSENCE Festival settles it by supplying the sign itself and attaching it to the booth. A sign built for one of these shows and carried to another in the same halls is a sign you will not hang.

The World of Asphalt rules are the best teaching example here, and the reason is structural. Most shows define a booth type by how many sides are open. This one defines it by depth. Anything under 20 feet deep is a standard exhibit at 10 feet, whether it sits in line, on a perimeter, on a corner or as a peninsula. At 20 feet deep and 400 square feet or more, a corner or perimeter booth goes to 15 feet and a peninsula to 20. So a perimeter booth has two different caps depending on its depth, and an exhibitor who reads the perimeter paragraph without reading the standard definition is wrong by five feet. Both versions carry no height limit for product or machinery.

The lowest published booth height in this guide is here too, and it is not set by a booth type at all. The ESSENCE Festival sells space as a single or a double and tells vendors that nothing should sit above the frame system of the booth, with the back panel at 88 inches. That is 7 feet 4 inches, lower than every drape height in this article. The show does not use booth-type vocabulary anywhere, and its published spatial rules are containment rules: merchandise and signage inside the footprint, nothing in the aisles, buy a second booth before load-in if you need the room.

At the opposite extreme is the otolaryngology meeting, which sets no height of its own and delegates the whole rule set to industry guidelines it credits without naming an edition year. It also attaches teeth to the delegation, reserving the right to alter, remove or rearrange a non-compliant display, and to do so at the exhibitor’s expense if nobody is there. Its entire published treatment of multi-level exhibits is one sentence saying exhibitors have the option. If you exhibit at this show, the rules you are held to are not the rules you can read, and the only fix is to ask the organizer which document and which year.

Two more clauses decide what you can quote in this city. The ARA Show exempts equipment manufactured in the normal course of the exhibitor’s business and displayed in its normal operating position from its height limits, which at an equipment show is the clause that decides the design. And the hematology meeting sets no general island height. Its 20-foot figures attach to hanging signs and to multi-level booths, so an island there answers to its sight line rule instead of a number, and the show states that variances will not be granted.

Working in New Orleans

Freight is the operational fact that shapes every job here, and the venue states it plainly: it cannot accept freight shipments or packages for exhibitors, organizers or contractors at any time. Everything moves through the official general contractor, with no exceptions written into the policy. The building provides no carts, dollies, pallet jacks or labor for exhibitor use, stores no crates or freight of any kind, and does not allow exhibitor-owned or leased vehicles to drive onto the exhibit floor. Loading through the lobby glass doors is limited to what one person can carry or roll through a single door. Plan the material handling before you plan the build.

Weight and structure run on long clocks. Equipment over the stated limits needs detailed plans showing the load on all points and the proposed method of redistribution. They have to be certified by a licensed structural engineer and in the venue’s hands three months before the event, and the venue may send outside consultants to verify in the field at your expense. That is the longest overweight lead time here, against 60 days in Detroit. Multi-level and enclosed booth plans are due 60 days before move-in with a structural engineer’s stamp on the occupant load, plus an approved special event application whose fee is based on the net square footage of the exhibit. Tents and canopies need 60 days and the approval of both the venue and the New Orleans Fire Prevention Division, and nothing may be anchored to the floor, the walls or the columns.

Two placement rules are easy to miss and expensive to discover on site. A multiple-story booth may not sit under a passenger or utility truss way, which removes part of the floor from consideration before you start designing. And exhibits must stand 20 feet clear of the entrance lobby doors and the rear loading dock doors.

One labor note, and it comes from a show rather than from the building. The restaurant association’s showcase lists a non-union hall among what a booth buys, and it is the only labor statement in any New Orleans show document we have read. Treat it as that show’s description of its own floor, confirm the scope with show management, and do not carry it across to the other six.

Washington DC

Washington is two buildings in two jurisdictions, and the distinction is not cosmetic. Three of the five recurring shows name the Walter E. Washington Convention Center in the District, and a fourth publishes only the city. Sea-Air-Space sits at the Gaylord National in National Harbor, Maryland, which is a different state, a different building and a different airport run.

Venue	Exhibit space	Ceiling height	Maximum permitted booth height	Floor load
Walter E. Washington Convention Center	Halls A to C 473,000 usable sq ft, Halls D and E 230,000	Predominantly 30 ft in Halls A to C, with a 10,000 sq ft pocket at 12 ft	Set by the show	350 lb/sq ft in all exhibit halls
Gaylord National Resort & Convention Center	Prince George’s Exhibition Hall 178,787 sq ft, with no gross or net label from the venue	24 ft, from a dimension string rather than a stated ceiling	20 ft including signage, carried by a show document	–

The Walter E. Washington publishes the numbers an exhibit company needs. One of them is a detail almost no venue bothers with: predominantly 30 feet in Halls A to C, with a 10,000 square foot area at 12 feet on the south side of Hall A. A 12-foot pocket inside a 30-foot hall is the kind of thing you discover with a tall booth already on the floor. The 350 pounds per square foot appears under floor load capacity on both of the venue’s current hall-group pages, so it covers all five halls. Halls A, B and C are on the lower level and Halls D and E on the upper level, which a show states in its own exhibitor pages.

The freight numbers at this building have an unusual shape. Halls A, B and C have 39 usable enclosed docks, three drive-in doors at 25 feet wide by 15 feet high, and two overhead doors at 19 by 15. Hall D has ten covered docks with a 16-foot drive-in. Hall E has ten covered docks with a 20-foot drive-in. Every door in the building is 15 feet high and they differ only in width. So height is one building-wide constraint here and width is the per-hall question.

The Gaylord figures need care in both directions. Its 24 feet is the third value in a length by width by height dimension string on the venue’s own capacity chart, and the page never uses the word ceiling. That makes it a room dimension rather than a stated clear height to a named obstruction. The 20-foot booth height in the table comes from a show document for an event in that hall and not from the building. The hall’s area needs the same caution: sections A through E sum to 178,787 square feet, while the hall’s own printed 299 by 602 multiplies to 179,998. Use the 178,787, which its own parts support, and do not derive an area from the dimensions.

Booth rules by show:

Show	Booth types and maximum height
Emerging Technologies for Defense Conference and Exhibition	Island 20 ft, including the top of any signage, and the organizer writes it as a general limit Linear backgrounds to 8 ft including signage, that 8 ft only in the rear half, with a 4 ft restriction on all materials forward of it Peninsula is exposed on three sides and given no maximum, only a line of sight rule: backing onto two linear booths, its back wall drops to 4 ft within 5 ft of each aisle Corner, perimeter, end cap, split island, extended header, towers and walk-through are not defined Every booth must also comply with the host facility’s height restrictions for its location on the floor, and the facility’s rule is not printed A product that cannot meet the sight line requirements may be excepted with show management’s approval Multi-level shares a heading with tents and canopies: plans go to show management by a deadline deferred to the service manual, and a fire watch is required on all covered and second story booths, with no area threshold, height, engineer stamp or egress requirement stated
AUSA Annual Meeting and Exposition	No height is published, and the exhibitor resource center is a sign-in portal What the show publishes instead is a shape rule: certain booth widths cause aisle displacements and will not be permitted, with 30 by 30, 30 by 60 and end cap booths given as the examples A second rule governs who may exhibit at all, requiring a National Partner membership, with an exception for first-time small businesses The 2027 rate is 62 dollars per square foot, or 6,200 dollars for a 10 by 10 The show says it is reviewing its floor plan and space allocations and expects to publish that strategy in early 2027, so the width rule may move

Four of these five publish no booth height, and four of the five publish no hanging sign rule. These are not small events. They include the army’s annual meeting, a major gastroenterology meeting and a ten-day auto show. In the capital, an exhibitor planning a booth cannot learn what they are allowed to build from any show’s published rules, which is the clearest argument here for having someone make the calls on your behalf before you design.

The one show that does publish figures then hands the real answer back to the building. The defense exhibition caps an island at 20 feet including the top of any signage, with the word generally attached to the figure by the organizer itself. It holds linear backgrounds to 8 feet in the rear half with 4 feet forward. It defines a peninsula and gives it no maximum height at all, only a sight line that drops the back wall to 4 feet within 5 feet of each aisle. Then it requires every booth to comply with the host facility’s height restrictions for its specific location on the floor, and it does not print the facility’s rule. One trap in that row: the phrase including the top of any signage belongs to the 20-foot booth height, not to a hanging sign. The show’s own hanging sign maximum is written as varying by venue, with no figure anywhere. Renderings go to show management and must state the height at which the sign will be installed, no deadline is given, installation runs through the host facility, and outside rigging companies are not allowed access to the building’s rigging points.

That show also carries the broadest fire watch requirement in this guide. A fire watch is required on all covered and second story booths, flat, with no area threshold of any kind, where other shows and buildings set 300 or 400 square feet. Price it in before you propose a conference room inside the booth.

The army’s meeting restricts the shape of the space it sells rather than what you build in it, and no other show in this guide does that. Certain booth widths cause aisle displacements and will not be permitted, with 30 by 30, 30 by 60 and end cap booths given as the examples. The policy text behind the rule is not published. Exhibiting at all requires a National Partner membership, with an exception for first-time small businesses, and the 2027 rate is published at 62 dollars per square foot, which is 6,200 dollars for a 10 by 10.

Two location notes keep this city’s table honest. The gastroenterology meeting publishes its city and not its building, so no hall and no venue statement comes from the organizer. The auto show publishes its own area names, an On the Go Hall, a Performance Hall, an Exotic Cars area and a Commercial Truck Zone, while the building publishes Exhibit Halls A to E. For the 2026 edition the organizer mapped two of them, putting the Performance Hall in Halls D and E on Level Two and the On the Go Hall on the lower level. It does not agree with itself on how far the On the Go Hall reaches, one page giving Halls A and B and another giving Halls A, B and C, and it has published no 2027 area map at all. Expect your space assignment in the building’s letters, and confirm which of them your area occupies.

Working in Washington DC

The Walter E. Washington writes its multi-story rules as conditions rather than as a height, and the conditions are specific. Multi-story booths, covered assembly areas and storage closets are permitted provided the regulations are met. An enclosed area needs a porous roof or cover so the building’s sprinklers can reach inside it. Occupancy on a second floor load-bearing area runs at one person per 15 square feet and may not exceed 25 people. Two means of egress are required from any load-bearing area or covered assembly over 400 square feet unless the building approves otherwise. Enclosed areas need audible smoke detectors. Plans go to the building at least 90 days before installation, certified and sealed by a licensed structural engineer or a licensed architect.

One of those rules is shaped unlike any other in this guide and it needs reading slowly. A fire prevention attendant must be on duty at all times that the exhibit hall is closed, from move-in to move-out. That is the opposite of a fire watch during show hours. It is an overnight cost that runs the length of the event, and it sits in the same building as a show rule requiring a fire watch on every covered or second story booth with no threshold at all. Two authorities, two rules, and nobody has reconciled them for you.

Two smaller figures belong in your file. Vehicles in the hall are limited to a quarter tank of fuel or five gallons, whichever is less, which is close to a national standard: the same pair appears in Houston’s shows and in Saint Paul’s city code. And the height limits on the venue’s exhibitor services page apply to storage rather than to booths, with crate storage capped at 20 feet wide by 20 long by 12 high and dock bay storage at 8 feet off the loading dock platform. Those are useful planning numbers for the crates and they are not permission to build to 12 feet.

Minneapolis and Saint Paul

The Twin Cities work as one market because the shows and the exhibitors treat them as one, but they are two cities, two operators and three buildings, and what each one publishes about itself is not comparable. Minneapolis documents its halls as thoroughly as any building in this guide. Saint Paul publishes less, and what we know about it comes mostly from the shows.

Venue	Exhibit space	Ceiling height	Maximum permitted booth height	Floor load
Minneapolis Convention Center	Five halls, 475,200 sq ft, of which Halls B to E are 376,200 contiguous	30 ft 6 in clear to lowest truss in Halls B to E, 27 ft 10 in for Hall A	Set by the show	350 lb/sq ft in all five exhibit halls
Saint Paul RiverCentre and Roy Wilkins Auditorium	RiverCentre Halls A and B 68,699 sq ft, Roy Wilkins Exhibition Hall 31,683 and Auditorium 44,800	RiverCentre 27 to 39 ft, Roy Wilkins Exhibition Hall 15 ft, Roy Wilkins Auditorium 52 to 60 ft	Set by the show	–

Minneapolis names its measurement type, which matters more than the figure does. Its 30 feet 6 inches is a clear height to the lowest truss, not a ceiling, which means it is the height you can design to rather than a number measured somewhere you cannot build. Hall A is lower at 27 feet 10 inches. The floor load is published space by space: 350 pounds per square foot in all five exhibit halls, 100 in the ballroom and the meeting rooms, and 150 in the registration areas. If a heavy display is going anywhere other than an exhibit hall, the number changes by a factor of three and a half.

The freight detail here is the fullest of the ten markets, and the halls are not interchangeable. Hall A has five enclosed bays at 11 feet 6 inches wide with underground dock access, a dock height of 4 feet, and one drive-in door to the hall at 18 feet high by 19 feet 11 inches wide. Halls B through E have covered docks, with seven bays at 11 feet 6 inches in Hall B and eight bays at 15 feet each in Halls C, D and E. Three freight elevators serve the building, one rated at 20,000 pounds and two at 10,000. Halls B to E share an 88,000 square foot fenced and lighted marshaling yard, while Hall A marshals on 16th Street. If you are moving wide crates, the hall assignment decides the dock before anything else does.

Saint Paul’s floor load is the cell this guide cannot fill, and the building’s own documents are not where the useful facts came from. A show’s prospectus tells you the RiverCentre exhibit hall floor is gray concrete, which is a surface and not a load. A show’s exhibitor FAQ tells you that both the Upper and Lower Wilkins spaces take vehicles, that each exhibit hall has only one drive-in door, and that most vehicles are therefore loaded in a staging area near that door. The same FAQ says there are fewer dock spaces than in previous years and gives no count. One more useful piece: the Rotunda is part of the RiverCentre exhibit hall rather than a separate room, so a space described as being in the Rotunda is still on your floor plan.

The ceiling spread across these three buildings decides what can travel between them. The Roy Wilkins Exhibition Hall is 15 feet. Minneapolis Halls B to E are 30 feet 6 inches. A booth designed for one of those rooms does not travel across the river, and a hanging element designed for Minneapolis will not fit in the Roy Wilkins Exhibition Hall at all.

One utilities detail belongs with the space selection rather than the build. The Minneapolis Convention Center’s floor boxes sit on 30-foot centers, and one in three of them includes a drain. The rest are electrical. If your booth needs water, that fact decides where on the floor it can go.

Shows in Minneapolis and Saint Paul

This market inverts the pattern that holds everywhere else in the guide. Here the consumer shows publish the detailed height rules and the professional shows publish almost none.

Booth rules by show:

Show	Booth types and maximum height
Northwest Sportshow	Standard booth, one or more 10 by 10 units in a straight line: fixtures and components to 8 ft, plus 2 ft for back wall identification signs, so 10 ft overall, building construction permitting Perimeter wall exhibits: back walls may rise continuously to whatever the building ceiling permits, with show approval, so there is no figure Peninsula and island take no flat cap but three bands measured from the aisle: under 4 ft within 10 lineal feet of an adjoining aisle, under 8 ft within 20 lineal feet, and up to 16 ft beyond 20 Linear bulk exhibits take two of those bands, 4 ft within 10 lineal feet of an aisle and 8 ft beyond it Towers are permitted at 3 ft by 3 ft and up to 16 ft, and closing room walls take 8 ft plus 2 ft for signs Anything over 12 ft needs drawings with a reviewing structural engineer’s stamp, 60 days before the show opens These are the 2026 manual’s figures, and the organizer has since posted an official 2027 manual
Minneapolis Home + Garden Show	No types are defined, and the height rule is keyed to booth size rather than booth type The rental comes with an 8 ft back drape and two 3 ft side drapes Exhibit tables, stands and displays may extend forward all 10 ft from the rear drape at 8 ft, a full-depth build with no front-zone step-down Signage cannot go above 8 ft in a space smaller than 20 by 20, and above that gate no maximum is stated Island booths of 40 by 40 or more may have exceptions to review with a sales consultant No line of sight rule and no distances appear, only containment: nothing extends into the neighboring exhibit, outward-facing sides are finished and carry no marketing, and nothing is displayed outside the booth Any exhibitor incorporating a ceiling needs show management approval regardless of size
Northern Green	A standard booth is 10 by 10, with 8 ft allowed only in the rear half and a 4 ft restriction on all materials forward to the aisle A 20 ft wide end cap may not have a back display more than 10 ft wide, 5 ft from center, though the accompanying image is labeled as a 10 by 20 end cap The document then sends the rest away, saying other booth configurations can be found in the industry association’s guidelines, and linear, peninsula, island, perimeter, tower and bulk are all undefined here The rental includes an 8 ft pipe and drape back and 3 ft draped side rails Exhibits stay wholly inside the contracted space and may not obstruct a neighbor’s view Multi-level is not addressed The same rules sit in the organizer’s 2027 exhibitor contract, which credits the industry association’s 2023 North American Update, and one detail is printed two ways: the FAQ gives the identification sign as 7 in by 44 in and the contract as 17 in by 11 in
Star of the North Meeting	No types are defined and no heights are given The one shape rule is a purchasing rule rather than a build rule: no end caps, and an exhibitor requesting two corner booths must take a minimum of 20 by 20 or larger Pricing is per 10 by 10 and per 10 by 20 with a corner premium, and the floor is divided into the show’s own color-coded sales zones rather than the building’s halls There is no line of sight rule and no setback, and multi-level is not addressed The prospectus gives one venue fact: the exhibit hall floor is gray concrete

Hanging sign rules by show:

Show	Hanging sign
Northwest Sportshow	Permitted only over bulk space exhibits, which the organizer defines as islands, peninsulas or some perimeter wall exhibits Banned outright in standard linear booths The maximum height is not a figure: signs hang at a height determined by hall construction, and the organizer says that limit is noted in the exhibitor kit No measurement point, size gate, weight limit, deadline or installer is stated Signs may not hang over or into neighboring exhibits or aisles, and may not contain or allude to discounts or prices
Minneapolis Home + Garden Show	A content restriction above 8 ft rather than a height limit: a sign above 8 ft may carry the company name and logo and may not advertise products or services No eligible types are stated and no maximum height above that threshold is given Signage may not be attached to the venue’s walls or pillars, and overhead inflatable signs are not permitted Hanging goes through the official show contractor at the exhibitor’s cost
Northern Green	A referral rather than a rule Asked whether anything may hang from the ceiling above a booth, the organizer answers that it depends where the booth is located, and that an exhibitor should contact show staff, who will connect them with venue staff No eligible type, size gate, maximum height, measurement point, setback, deadline or weight limit is published
Star of the North Meeting	Not stated for booths The only hanging item in the document is a sponsorship option, a company banner in the rotunda at the sponsor’s production expense, which is not a booth rule The booth’s own sign is described as a standard identification sign

Count it the way an exhibitor would. A consumer sport and boat show publishes the richest set of booth types in the market. A consumer home and garden show publishes a full-depth build permission and a signage gate. A professional horticulture trade show publishes two figures and sends every other configuration to an industry document. A professional dental meeting publishes no height at all. Two further professional shows publish nothing we could reach. A reader who assumes a professional audience means a professional rulebook will be wrong in this market.

The sport show’s island rule is the most distinctive height rule in these ten markets, and it does not fit a table cell. Every other show here caps a booth type at a number. This one makes the cap a function of distance from the aisle, in three bands. A fixture within 10 lineal feet of an adjoining aisle stays under 4 feet, one within 20 lineal feet under 8 feet, and one beyond 20 lineal feet may reach 16 feet. All three are subject to hall construction and the size of the space. The practical effect is that the tall part of an island has to sit in its middle. That is a design constraint rather than a height limit, and it changes the layout rather than the elevation. Its standard booth rule is unusual in a second way: 8 feet of display plus a 2-foot band for back wall identification, ten feet overall, with the building holding a veto. Anything over 12 feet needs drawings available for inspection with a reviewing structural engineer’s signature or stamp, submitted no later than 60 days before the show opens. Read the dates before you rely on any of it, because these are the 2026 manual’s figures and the organizer has since posted a 2027 manual.

The home and garden show keys its height to the size of the space rather than to the type of booth, which is the reverse of how every business-to-business show in this guide works. The rental comes with an 8-foot back drape and two 3-foot side drapes. Then it grants something most trade shows in this article forbid: tables, stands and displays may come forward the full 10 feet from the rear drape at 8 feet in height, with no front-zone step-down at all. Signage cannot go above 8 feet in a space smaller than 20 by 20, and above that gate the show states no maximum. What it does state above 8 feet is a content rule rather than a height rule: a sign up there may carry the company name and logo and may not advertise products or services. Overhead inflatables are not permitted. One caveat on using these two shows as evidence of a local pattern: they share an operator and large amounts of wording, so they are closer to one data point than two.

On the professional side the published record thins out fast. The horticulture show publishes an 8-foot rear-half maximum with 4 feet forward to the aisle and one end cap rule, then says in its own text that other booth configurations can be found in the industry association’s guidelines. The dental meeting publishes no height, and its one shape rule is a purchasing rule rather than a build rule: no end caps, and an exhibitor who wants two corner booths must take a minimum configuration of 20 by 20 or larger. It prevents the configuration at the point of sale instead of regulating it at the point of build, which no other show in this guide does.

Neither hanging sign answer in this market is a number. Asked whether anything may hang above a booth, the horticulture show answers that it depends where the booth is located and that show staff will connect an interested exhibitor with venue staff who can advise. The sport show says the limit is determined by hall construction and will be noted in the exhibitor kit, and the kit we have does not contain it. In both cases the answer exists somewhere and is not published, which is a different problem from a show that bans hanging signs outright.

One finding here reaches across the whole guide. At least seven shows in these ten markets send exhibitors to the same industry association’s display guidelines, and they are not all sending them to the same document. The horticulture show here and the brewers’ conference in San Antonio cite the 2023 North American Update. The defense exhibition in Washington links the 2019 edition. Four more, a San Antonio music educators’ show, a San Antonio toxicology meeting, a Houston oil and gas summit and a New Orleans medical meeting, name no year at all. A figure attributed to the guidelines without an edition year is not a citation, and if your show delegates its rules that way, the year is the first thing to ask for.

Working in Minneapolis and Saint Paul

Minneapolis regulates covered and multi-level exhibits by area and by covering rather than by height. An automatic fire suppression system, approved by the city fire prevention bureau and by the building, is required in three cases. A single-level booth with a ceiling over 300 square feet is caught. So is each level of a multi-level booth, including the uppermost level if it is covered, and an enclosed trailer over 300 square feet used as a walk-through or fold-out exhibit. Detailed drawings, schematics and the proposed use go to the building’s events department at least 60 days before move-in. The building cites a nationally recognized code as its authority, so expect the same thresholds to be applied as written rather than negotiated.

Rigging is published by space in Minneapolis, with a level of detail most buildings keep in a service kit. Ballroom points sit on approximately 18-foot centers at a maximum of 1,000 pounds per point, and meeting room points are limited to 500 pounds. A rigging plot has to include every piece of suspended equipment, its published point load and the final trim height by truss line, and hardware must carry stamped working load limits with a minimum 5 to 1 design factor. Those figures belong to the ballroom and the meeting rooms. Get the exhibit hall’s point loads from the building before you design a truss into a booth.

Across the river, the fire rules an exhibitor will meet are the city’s, quoted by the shows rather than by the building. Fuel in a tank may not exceed a quarter of its capacity or five gallons, whichever is less, which matches Houston and Washington and is close to a national standard. Propane inside an assembly occupancy is limited to 5-pound containers placed 20 feet apart, which is specific enough to change how a demonstration booth is laid out.

Philadelphia

Philadelphia carries eight recurring events in one building, and the most useful thing in it is not a disagreement between two shows. It is three shows that disagree with themselves.

Venue	Exhibit space	Ceiling height	Maximum permitted booth height	Floor load
Pennsylvania Convention Center	Seven halls, 679,000 gross sq ft, of which 528,000 contiguous on the 200 Level	29 ft low clearance and 51 ft high in Halls A to E, 15 ft and 14 ft low in Halls F and G	No limit, except two stories and 30 ft for covered and multi-level exhibits	350 lb/sq ft in all seven halls

Start with the ceiling, because this building publishes it as a pair rather than a figure. Halls A to E carry a 29-foot low clearance against a 51-foot high point. Halls F and G are 15 feet with a 14-foot low clearance. The spread between the halls of one building is wider than the spread between most of the cities in this guide, so the hall letter in your space confirmation decides what you can build before any show rule does.

Philadelphia is also one of only two buildings here that set a booth height of their own, and it sets one only for the covered case: no limit in general, with two stories and 30 feet for covered and multi-level exhibits. Everything else is the show’s business.

The building’s own documents do not agree about how much they will tell you. Its plan of operations publishes 350 pounds per square foot for all seven halls. Its rules and regulations carry no ceiling, no floor load and no booth height at all, routing those questions to the event manager and to its own drawings. One building, two of its own documents, one answer. None of the eight shows here restates a venue floor load, ceiling height or rigging limit, so the figures in that row stand on the venue’s documents alone. The venue’s own page adds the number that matters to a move-in plan: 45 loading docks across 679,000 gross square feet of hall, with 528,000 of it contiguous on the 200 Level.

Shows in Philadelphia

If you need one argument for why an exhibitor should not build to the last inch from a published rule, it is in this city, and it does not require comparing one show with another.

Booth rules by show:

Show	Booth types and maximum height
AIA Conference on Architecture and Design	In-line, which the organizer also calls linear, one side open to an aisle and usually 10 by 10: 8 ft on the back 5 ft and 4 ft on the front 5 ft Corner takes the same Perimeter 12 ft on the back 5 ft and 4 ft on the front 5 ft Island, aisles on four sides at 20 by 20 or larger, 20 ft for all fixtures, components and signage, anywhere in the booth Peninsula, split island, end cap and walk-through are not defined, and towers appear only as a submission trigger over 8 ft Three prohibitions are named outright: no side walls over 4 ft in the front half, no stacking above 4 ft near the aisle, and no banner stands, pop-ups or kiosks at the front corners Flooring is mandatory, with bare concrete not allowed Multi-level is permitted with approval, and the definition covers any ceiling, roof, canopy, fabric cover or tent Sprinklers are required for a single-level covered area at 300 sq ft and for a multi-level booth at any size, with engineer-stamped structural drawings, battery smoke detectors and an extinguisher in each covered area, all due March 18, 2027
Biophysical Society Annual Meeting	Only two types are defined, and the document contradicts itself on height All booths are 10 by 10 with 8 ft pipe and drape backs and 3 ft side rails Standard in-line: the back wall is limited to 8 ft in height and 4 ft in depth, and display material in the remaining 6 ft must not exceed 4 ft, so the tall zone is only the back 4 ft of a 10 ft booth Island, bordered on four sides by aisles: full cubic content may be used but all display material is restricted to 16 ft, with a sufficient see-through or walk-through area Section 24 then contradicts section 5, prohibiting backdrops or any part of a display above 8 ft and adding that nothing in the front half may be higher than 48 in, so the two have to be settled with show management A pop-up background may not exceed 8 ft and sits against the back wall Carpet is required A corner fee is charged with no corner definition and no corner height Multi-level is not addressed
PACK EXPO East	Height is set by footprint rather than by booth type, which is unusual, and the organizer publishes the scheme on its own FAQ page A booth of 599 sq ft and under takes a maximum of 12 ft A booth of 600 to 1,499 sq ft takes 14 ft A booth of 1,500 sq ft and over takes 18 ft No booth type is named or defined anywhere in that scheme The organizer then says setback and line of sight rules apply without giving them, and refers the exhibitor to the full rules and regulations
BIO International Convention	–
Philadelphia Auto Show	Three separate manuals cover three exhibitor populations at this one show, and their height rules differ None of the linear, perimeter, peninsula or island vocabulary appears; height is set per program and per hall Manufacturer display program, 2026 edition: 26 ft for the Main Exhibit Hall Commercial vendor program, 2026, and Custom Alley, 2027, in identical words: displays higher than 10 ft must be approved by show management in advance, and no manual states a figure above which approval is refused Manufacturer setbacks: 15 ft in front of all emergency exit doors, 5 ft from all columns, 3 ft on every public aisle and 2 ft on any border adjoining another display A commercial vendor’s sides stay open above the 3 ft divider rail In Custom Alley every vehicle sits at least 3 ft off the aisles, with barriers or stanchions around every display, though the 2027 floor plan legend reads a 2 ft setback against the manual’s 3 ft Vehicle fuel cannot exceed a quarter tank or 5 gallons, whichever is less No vehicle height exemption is published
PHS Philadelphia Flower Show	–
FAN EXPO Philadelphia	Space is published by exhibitor category and by area only, never by height Artist Alley standard is one 6 ft by 5 ft space with a skirted table, two chairs and two passes; Artist Alley premium is a 5 ft by 12 ft end cap with two tables; a retailer booth is a 10 by 10 with one unskirted table and a per-corner charge The only booth-type words used anywhere are end cap space and corner location No height figure is published, and the reason is a contract clause rather than a gap: the operator’s circuit-wide terms define the exhibitor manual, require compliance with it, and make its provisions confidential
Fierce Pharma Week	In-line, rear: 8 ft 3 in, given as 2.5 m, in the back 5 ft of the space In-line, front: no item over 4 ft within 5 ft of the aisle The next bullet in the same document prohibits any portion of an exhibit over 8 ft, given as the same 2.5 m, so the governing figure has to come from show management Corner in-line inherits all the in-line guidelines With three or more in-line booths combined, the 4 ft limit applies only within 10 ft of an adjoining booth Island, any size with aisles on four sides, 16 ft for the booth structure, draperies not included Peninsula, end cap and perimeter are not defined Every multi-story exhibit, occupied or not, and every fixture over 16 ft needs drawings and advance written approval at least 30 days pre-event, so the 16 ft island cap is also the submission trigger An occupied multi-story exhibit needs an engineer-stamped drawing including weight capacities

Hanging sign rules by show:

Show	Hanging sign
AIA Conference on Architecture and Design	Island only, with in-line, corner and perimeter each marked no in the organizer’s own table The size gate is 400 sq ft and larger, matching the island definition The top of the sign may be no higher than 20 ft and its bottom at least 8 ft That 20 ft is a separate line from the island’s own 20 ft, so the sign gets no height above the structure Anything rigged overhead is installed by the venue’s crew and ordered through the venue Due Thursday, March 18, 2027, stated as 60 days before move-in No setback or weight limit is given
Biophysical Society Annual Meeting	Not addressed as a category No permission, eligible type, size gate, maximum height, measurement point, setback, deadline, weight limit or installer appears The only use of the word hanging is inside a general ban on anything that interferes with another exhibitor’s view, which is about obstruction rather than permission, so this is unfound rather than banned A separate rule bans affixing signs to walls, drapes or outlets with nails, tacks, staples or tape, which is about attachment and not suspension
PACK EXPO East	Banned in a booth of 599 sq ft and under, stated inside the height rule rather than as a sign rule Nothing is published for the two larger footprints, so there is no figure and no measurement point for them
BIO International Convention	–
Philadelphia Auto Show	Only the manufacturer program permits them, and the height is derived rather than stated: the top of a hanging sign may not exceed the display height restrictions for the hall, which makes the cap the hall’s 26 ft No independent sign figure is published and the measurement datum is not defined Approval by show management by January 2 The commercial vendor and Custom Alley programs do not offer hanging signs at all, requiring free-standing signs, professionally manufactured and finished on all edges
PHS Philadelphia Flower Show	–
FAN EXPO Philadelphia	–
Fierce Pharma Week	Permitted over island booths of 400 sq ft or larger, no higher than 20 ft measured from the top of the sign to the floor, set back 10 ft from the adjacent booth rather than from the aisle No aerial rigging or hanging sign is permitted in an in-line booth, and corner in-line is caught by that too No sign-specific deadline is published: the 30-day written approval attaches to multi-story exhibits, fixtures over 16 ft and enclosed areas, not to signs

Three shows here contradict themselves, in three different ways. The auto show publishes three separate manuals for three exhibitor populations, at one show in one building, and their height rules differ by a factor of 2.6. A manufacturer display in the Main Exhibit Hall gets 26 feet. Everyone else gets an approval conversation at 10 feet. The biophysics meeting allows 16 feet for an island in one section of its terms and then prohibits any part of a display above 8 feet in another section of the same document, and the two sections also measure the front zone differently. The pharmaceutical week gives 8 feet 3 inches as its in-line maximum and 8 feet as its prohibition threshold in adjacent bullets, with the same metric figure attached to both. In each case the right move is to get the governing figure in writing from show management rather than to pick the one you prefer.

The 10-foot figure in the auto show’s vendor manuals is the trap in this city, and it is easy to repeat wrongly. Displays higher than 10 feet must be approved by show management in advance. That is a submission threshold, not a cap, because no manual states a height above which approval is refused. A summary that prints 10 feet as this show’s height limit has turned a conversation into a ceiling. The same shape appears in San Antonio, where a toxicology meeting’s only published height figure is also the point at which you must submit drawings.

At the other end of the quality range, the architecture conference publishes the clearest booth type table of any show here. In-line and corner booths take 8 feet across the back 5 feet and 4 feet across the front 5 feet. A perimeter booth takes 12 feet at the back on the same terms. An island at 20 by 20 or larger takes 20 feet anywhere in the booth, fixtures and signage included. It then names three prohibitions outright rather than leaving them to be inferred: no side walls above 4 feet in the front half, no stacking product or crates above 4 feet near the aisle, and no banner stands, pop-ups or kiosks at the front corners. Flooring is mandatory and the document says so bluntly: the hall floor is not carpeted and bare concrete is not allowed.

That same show carries the strictest sprinkler rule of the ten, and the pairing inside one building is the point. A single-level covered area is caught at 300 square feet, and a multi-level booth is caught at any size at all, with engineer-stamped structural drawings required and a March 18, 2027 deadline. In the same halls, the biophysics meeting does not mention multi-level exhibits anywhere. One show requires sprinklers and a stamped drawing for any second level; the other is silent, which means you ask rather than assume.

Hanging signs in this city show two patterns that travel to other markets. The architecture conference states both ends of the sign, with the top no higher than 20 feet and the bottom at least 8, which fixes the sign’s own depth at 12 feet without the document saying so. Two other shows state both ends: Gen Con in Indianapolis, at 22 and 12, and IWF West in San Antonio, which fixes the band a sign may hang in. And the architecture conference gives the sign no height above the structure at all: its island cap and its sign cap are both 20 feet, written as separate lines in the same table. A cardiology meeting in Houston does the same thing at the same figure. Everywhere else in this guide, a permitted sign is allowed to rise above the booth.

The auto show derives its sign cap instead of stating one. The top of a manufacturer’s hanging sign may not exceed the display height restriction for the hall, which makes the cap the hall’s own 26 feet with no independent sign figure anywhere. The rule also names the top of the sign as the controlled point without saying what it is measured from. Approval runs through show management by January 2. The vendor and Custom Alley programs do not offer hanging signs as a category, requiring free-standing or floor signs instead. The vendor manual adds a finish rule blunter than any other in this guide: signs must be professionally manufactured and finished on all edges and sides, with no plastic letters, shoe polish or homemade signs anywhere.

One timing note for the richest row in the table. Every manufacturer figure above, the 26-foot cap and the sign rule and the setbacks, comes from the 2026 edition of the show management manual. The 2027 edition is not posted. In the 2026 cycle the equivalent documents appeared in late November and mid-December, and the 2027 show opens two weeks earlier than the 2026 one did, so that is the window to check.

Three of these eight shows publish no booth height, and the three reasons are three different problems. The biotechnology convention names its building only on its sponsorship page, and in two different forms there, while its own venue page still describes the previous host city. The flower show issues its vendor manual only after acceptance and through a portal, and says so in its own words. Its long public rulebook is a competition rulebook, and its height figures are staging caps rather than booth heights. Printing one of them as a booth height would be a visible error to a horticultural reader. The comic convention’s manual is made confidential by its operator’s own contract terms, which is a different category from a document we could not find: for that family of shows, an exhibit builder cannot plan from public information at all. The packaging show used to belong on that list and no longer does. Its organizer now publishes a banded height scheme on its own FAQ page, while the complete rules and regulations it calls an integral and binding part of the exhibit contract sit behind a document-hosting link, so the figures in the table above are the FAQ’s and the setback and line of sight rules behind them are not public.

Working in Philadelphia

The most commercially useful document at any building in this guide is here, and it answers the question an exhibit builder’s customer actually asks: what may my own staff do without hiring labor. The Pennsylvania Convention Center’s enhanced exhibitor work rules let full-time employees of the exhibiting company set up and tear down their booths, in the document’s own phrase, “without limitation to size”. They may use their own power tools and ladders up to 6 feet, hang graphics and signage, and install signage and floor coverings. They may install non-rented AV equipment for non-public use, open boxes and stock shelves, distribute their own non-bulk product and literature inside the booth, and maintain their own display equipment after the initial setup. Most buildings that permit self-setup cap it at a booth footprint. This one expressly does not.

Two gates sit on all of that and both matter when you quote a job. The freedoms apply only while no exhibitor-appointed contractor is contracted to set up or dismantle the booth. And the dividing line for the work itself is rented versus owned and public versus non-public rather than booth size: show labor sets up rented equipment, registration, and public-use computers and tablets, including when they are used to collect data.

The practical ceiling on self-installation here is not written as a height. It is the ladder. The work rules grant a booth of any size to your own crew, and the building’s safety guidelines cap the ladder at six feet, do not permit hoists, and require riggers for heavy objects. So an exhibitor may legally build anything in this hall and can physically reach about ten feet of it. That gap is where a labor estimate either holds or falls apart.

Vehicle unloading is limited by the type of vehicle rather than by the size of the booth. Sedans, SUVs, pickups and vans qualify, and they must be non-commercially registered. Trailers, tag-along rentals, bobtails and stakebeds do not qualify. Within that, your own dollies, luggage carriers, non-hydraulic carts and two- to four-wheel hand trucks are permitted.

One stability note, because you may be quoting these rules to a client. The work rules one-sheet exists in a March 2023 edition and a January 2026 edition, and every operative exhibitor rule in them is word for word identical. What changed between the two is the date and the name of the company operating the building. A copy from 2023 is out of date on who runs the hall and current on what your crew may do.

Last, an attachment rule that is absolute and catches people out. Decorations may not be taped, nailed, tacked, stapled or otherwise fastened to ceilings, painted surfaces, columns, fabrics, doors, windows or walls. Glitter is not permitted in the building at all.

Detroit

Detroit is one building and four shows, and the thing worth reading twice is about a single hall.

Venue	Exhibit space	Ceiling height	Maximum permitted booth height	Floor load
Huntington Place	Level 2 Halls A to D 624,022 sq ft, Level 1 Hall E 99,465, with no gross or net label from the venue	30 ft in Halls A to D, 18 ft 8 in for Hall E	Two venue documents disagree: 22 ft for a multi-level build, and 25, 19 and 15 ft by area	300 lb/sq ft in Halls A to D, 650 in Hall E, 150 on the Square

Hall E is the hall a reader would write off, and it carries the highest floor load in the market by a wide margin. It sits on Level 1 at 99,465 square feet with a ceiling of 18 feet 8 inches, where Halls A to D have 30 feet. Every other characteristic it has is a constraint. Then the load capacity table gives it 650 pounds per square foot against 300 in Halls A to D. The weakest hall for headroom is the strongest hall for weight, and that decides whether you accept or refuse a space assignment.

The main floor is not uniformly 300 either. The same table notes that certain areas of Hall B and Hall C have a reduced capacity of 220 pounds per square foot, and directs an exhibitor to the building’s engineering contact for the size and location of those areas. Huntington Place Square is separate again at 150. If you are placing weight, the figure depends on where in the building you land, not on the building.

More than 300 can be accommodated, and the building says so in its own planning guide: loading above that figure depends on the location, the physical dimensions and the adjoining loading, and show management has to get the venue’s approval. The plan needs a Michigan engineer’s stamp and goes to the venue at least 60 days before the first move-in day. That is a real lead time on a heavy exhibit, and it runs through show management rather than directly.

The booth height cell in that row says conflict, and the conflict is between two of the building’s own live pages. Its exhibit hall guidelines say a multi-level booth’s highest floor may not be more than 18 feet above the hall floor and its highest point not more than 22 feet, with the size limitation itself left to show management. Its fire department page, under a double-deck heading, gives a maximum structure height of 25 feet in Halls A to D, 19 feet for booths under the dividing line of each hall, and 15 feet in Hall E. Both are the venue’s own, both are undated, and neither says it replaces the other. A build to the lower of the two figures in whichever location you are in satisfies both, which in Hall E means 15 feet.

Shows in Detroit

Houston and San Antonio show organizers disagreeing about figures. Detroit shows four organizers who do not agree on what kind of thing a booth rule is.

Booth rules by show:

Show	Booth types and maximum height
Detroit Auto Show	No booth height is published The manual confirms that height restrictions exist without stating them, and a display exceeding them, or varying from what show management approved, must be modified on site The floor is governed by easement instead: 25 ft or 25 percent of the exhibit space depth on the aisle side, 10 ft or 10 percent on a contiguous border, whichever is less in each case, and vehicles 2 ft off both The easements apply vertically as well as in plan A lighting truss sits at least 24 ft from floor level, which is a minimum and not a cap Multi-level is permitted with no height of the show’s own
Detroit Autorama	A 10 ft general cap, which show management can lift in writing, and it is a booth height rather than a double-deck figure The booth may not exceed the space contracted, and every booth must be completely finished on the back Space is sold in six footprints: 10 by 10, 10 by 20, 10 by 30, 10 by 40, a 10 by 20 end cap and a 20 by 20 end cap No pop-up tents or other non-fire-retardant material over the top Vehicle exhibitors answer to a separate rule set that adds no height, no setback and no multi-level rule, only the venue’s requirements for fuel, batteries, fire protection, fluid leaks, electrical equipment and hazardous materials A modest identification sign naming modifications, builders and equipment is allowed, while advertising at any scale needs separately approved paid commercial space
The Battery Show North America	Nothing is published The exhibitor portal is gated, no rule document is linked on any public page, and the operator’s own terms make the manual confidential No equipment or product exemption is published What the show does publish is its price, 48.75 to 56.50 dollars per square foot depending on booth size

Hanging sign rules by show:

Show	Hanging sign
Detroit Auto Show	No eligible type, minimum size, maximum height or measurement point is given Two real rules do apply: the structural loads imposed by all rigging from the overhead steel must be approved before installation by the venue’s own Review Engineer, and the stringing of advertising banners, balloons and pennants is strictly prohibited

The auto show sets no booth height at all and governs the floor by easement instead, which no other show in this guide does. An aisle side easement runs 25 feet or 25 percent of the exhibit space depth, whichever is less. A contiguous border easement runs 10 feet or 10 percent of depth, whichever is less. Vehicles sit at least 2 feet off aisles and borders. A sign over 5 feet wide and 2 feet deep sets back at least 15 feet from the contiguous border and 2 feet from an aisle, and a smaller sign 2 feet from an aisle and 6 feet from the contiguous exhibitor. Then comes the clause that turns all of that into a height rule: every exhibitor space easement also applies vertically, to suspended structures and signs in the exhibitor’s air space. So a show that publishes no hanging sign height still governs where a hanging sign may be, and the setbacks you measured on the floor plan apply above your head.

One figure in that manual reads like a cap and is the opposite. A lighting truss may be mounted as high as the building ceiling allows but at least 24 feet from floor level. It is a minimum, and an exhibitor who treats 24 feet as the limit has inverted the rule.

Autorama sets the lowest general booth cap of any trade show here: 10 feet from the floor, without prior written permission from show management. The permission clause is the important half, because this is a cap with a door rather than an absolute. Two cautions travel with it. The page carrying the figure names no venue, no city and no hall, and its menu covers a dozen of the operator’s show cities, so it is a series-wide rule as it stood in early November 2026 rather than a Detroit document. And the cap is a general booth height, not a double-deck figure, so it does not speak to the building’s own multi-level conflict. The same page carries one scheduling line for your calendar: move-in is not allowed on Friday.

The battery show is unusually open about one thing and closed about everything else. It publishes its price, 48.75 to 56.50 dollars per square foot depending on booth size, which few shows in this guide do. Its display rules are a different matter. The exhibitor portal is gated and no rule document is linked on any public page. The operator’s own exhibition terms then define the exhibitor manual, require compliance with its provisions, and treat those provisions as confidential information. For that family of shows, and the comic convention in Philadelphia belongs to it, an exhibit builder cannot plan from public information at all. No equipment or product exemption is published either, which at a battery and electric vehicle technology show is the gap that matters most.

MagicCon’s route to a rule is a conversation rather than a document. Its exhibiting page is a contact form that prints the venue and the dates and nothing else, and its exhibitor manual is listed as coming soon. Detroit is its first edition in this building.

Working in Detroit

Multi-level work here answers to two authorities at once and both have to be satisfied. The building’s exhibit hall guidelines require certification by a registered Michigan-licensed engineer, with plans then going to the event services manager and the fire marshal for review, and note that fees may apply. The fire department page requires a stamped seal from a Michigan-licensed engineer and an egress plan for emergency exit, sets one smoke detector for every 900 square feet of continuous ceiling, and requires sprinklers and hardwired smoke detectors. That last requirement carries a trade you can price: a sprinkler system may not be required, subject to fire marshal approval, if the exhibitor provides 24-hour security at their own expense.

The auto show adds a layer of its own on top of the building’s. A two-story or large solid structure, suspended structures included, is acceptable but may not sit inside a designated easement area. An upper deck holding more than 50 people needs two means of egress. Any enclosed exhibit of 100 square feet or more, two-story exhibits included, needs hardwired smoke detectors tied into the building’s system on their own dedicated 24-hour power supply. An overall ceiling structure may not be built from solid material such as wood, drywall or cement, and nothing may impede the building’s own fire protection.

Two rigging facts round out the city. Structural loads imposed by any rigging from the overhead steel must be approved before installation by the venue’s own review engineer, which is an approval step rather than a published limit. And the stringing of advertising banners, balloons and pennants is strictly prohibited, so the cheap overhead branding that works in other halls does not work here.

Phoenix

Phoenix is the smallest market here on show rules and the best documented on the building. Neither of its two recurring shows publishes a booth height or a hanging sign rule we can attribute to this campus. In the semiconductor show’s case the reason is worth knowing before you plan around its website: as of early November 2026 its own home page still served its 2015 edition, thanking participants for attending that year, with no working navigation to an exhibitor section. The venue publishes almost everything else, in more detail than any other building in these ten markets.

Venue	Exhibit space	Ceiling height	Maximum permitted booth height	Floor load
Phoenix Convention Center	Upper level 190,000 sq ft, lower level 312,500, South Building 143,400, with no gross or net label from the venue	35 ft upper, 32 ft lower	Set by the show	300 lb/sq ft upper, 350 lower, 600 in the South Building

The sharpest contrast in this guide sits inside this one campus. The South Building carries double the floor load of the upper level, 600 pounds per square foot against 300, and one tenth of the rigging capacity, 250 pounds per point and from low steel only, against 2,500 pounds per point. An exhibitor planning a heavy machine goes south. An exhibitor planning a hung structure does not. Neither fact is discoverable from the building’s name or its square footage, and the qualifier about low steel has to travel with the 250.

The venue states each hall in a single sentence, which is why so much is known about it. The upper level exhibition hall is 190,000 square feet with a 35-foot ceiling, described by the venue as virtually column-free, with 300 pounds per square foot and 2,500 pounds per rigging point. The lower level is 312,500 square feet with a 32-foot ceiling, contiguous, running under Third Street to connect the North and West buildings, with 350 pounds per square foot and the same rigging capacity. One layout detail from the same source does more than it looks: the lower halls are scored on a 10 by 10 grid for booth layout and on a separate 30 by 30 grid for utilities.

The freight figures here are the most precise of the ten. The upper level dock is reached by a semi-truck ramp with 16 feet of clearance and has 18 truck bays, three ramps and three roll-up doors, two at 22 feet wide by 16 high and one at 18 by 17. The lower level has 20 truck bays, three ramps and three roll-up doors, two at 20 by 16 and one at 22 feet 8 inches by 16. The campus publishes 61 loading docks in total, which does not conflict with those two counts because they are per dock area.

One naming point will save a misunderstanding. The North and West buildings number their halls rather than lettering them, and Exhibition Hall 3 cannot be used independently. A space confirmation in Phoenix names a building and a number, and the shows here name buildings and floors rather than halls, so match the two carefully before you plan a move-in.

SEMICON West arrives in Phoenix with its 2027 edition, after an autumn 2026 edition in San Francisco, and the city becomes its long-term home. That governs every document connected to it: any rules written before 2027 were written for a different building in a different state. A show in its first year in a new building is the situation many exhibitors reading this are in, and the honest answer for this one is a date rather than a document. The organizer says on its own pages that the rules open in mid-November and that a rules document follows in late November.

The link that is posted in the meantime is the best argument here for checking a document’s cover before you build to anything in it. The show’s exhibitor service center links a file labeled as its 2026 exhibitor rules, served from a 2026 path. The file’s own title abbreviates 2024. Its content describes the San Francisco convention center the show has just left and routes audiovisual work to a San Francisco union local. And its first heading is the industry template’s own title, with two of the template’s fingerprint sentences present word for word and no association credit anywhere in the document. An exhibitor following the show’s own navigation downloads a generic template, believing it to be the show’s rules, for a city the show no longer uses, in an edition two years older than its label.

One 2027 fact is already published and it is the most useful scheduling detail in the ten markets. The move-in schedule carries a dark day in the middle of it: Sunday, March 28, 2027 is marked as Easter, with the convention center closed and no exhibitor move-in, set-up or freight received. No other show in these ten markets has one. It turns a four-day move-in into three, which changes the labor plan and the crew size for a large booth, and it is published now while the rules are not.

Phoenix Fan Fusion’s exhibitor material sits behind a password panel on its own site, so the route to its rules is the organizer rather than a document. Its pages do name buildings and floors for its programming, placing celebrity panels in a West Building ballroom and its photo operation in a North Building hall, and they assign no building at all to the exhibit or vendor hall. On this campus that is a real question rather than a detail, because the buildings differ by a factor of two on floor load and a factor of ten on rigging.

Working in Phoenix

Multi-level exhibits here answer to the city, which no other building in this guide does. A multi-level booth is treated as a structure and needs a building permit and an inspection before it is used. The city’s planning and development department approves the installation and the intended function of any multi-level exhibit meant to carry people. Construction documents must be stamped by an Arizona licensed structural engineer, the final installation may not deviate from the stamped documents, and final approval comes from the department rather than from the venue or the show. Build the permit review into the schedule, because it is not a conversation with show management.

The occupancy rule here is the clearest version of a trade-off this guide sees written two different ways. A two-story booth with only one means of egress from the upper level must post a maximum occupant load of ten people on the second level. The Walter E. Washington, by comparison, requires two means of egress above 400 square feet and caps occupancy at one person per 15 square feet to a maximum of 25. Phoenix prices the single stair at ten people. Washington requires the second stair. Same question, two answers, and the one that applies is the one in the building you booked.

Three more fire rules shape the design. A covered exhibit or booth over 300 square feet needs prior approval and additional automatic sprinkler protection. Vehicles are treated as covered structures, with recreational vehicles, campers, tractor-trailers and any other vehicle having more than 120 square feet of ceiling requiring an operational smoke alarm per divided section, which no other building in this guide states. And two clearances apply to everything you bring: storage stays 18 inches or more below the sprinkler head deflectors, and a three-foot clearance is required around fire extinguishers, hose cabinets, standpipe connections and defibrillators.

The venue’s real instrument of control is not a height limit at all. It is the floor plan. The building requires the plan to show every exit, aisle space, storage area, booth space and bulk exhibit. It also wants the width of the aisles, with a minimum of 10 feet throughout the floor, the drapery height, the location of exhibits on the utility grid, and the service desk. A plan that is missing any of those is where a schedule starts slipping.

What to do with all this

Four patterns run through the markets above. Each one will save more money than any single figure in the tables, and all four sit on top of the rules an exhibitor has to satisfy anywhere in the United States.

The height rule is almost never the building’s, and in this tier it is often nobody’s. Two of the fourteen venues here set a booth height of their own. The Pennsylvania Convention Center sets no general limit and allows two stories and 30 feet for covered and multi-level exhibits. Huntington Place sets one twice, on two of its own live pages, and the two do not agree. The other twelve leave the question to the show, though in one of them, the Reliant Center in Houston, a 25-foot island rule of the venue’s own reaches exhibitors through a show document. And the show frequently leaves it unanswered. Of the 57 recurring shows in these markets, 28 publish a booth height you can build to and 29 do not. Only 13 publish a hanging sign height, and fifteen more answer the question without giving a figure.

The floor is where the real differences live, and this is the tier where it decides the job. These ten markets run combines, trucks, excavators, asphalt plants and machine tools onto the floor. Five of the fourteen buildings publish no floor load at all. Among those that do, the spread runs from 150 pounds per square foot to 1,000, the widest in this series of guides. At the top are 1,000 in four halls of the Houston convention center, carried by a show document rather than by the building, 650 in Detroit’s Hall E, 600 in the Phoenix South Building and 500 inside New Orleans’s drawn heavy load zone. Then 350 as the common figure, 300 across Detroit’s main floor and Phoenix’s upper level, 220 in unnamed pockets of two Detroit halls, and 150 on Huntington Place Square. Ceilings get discussed constantly and floor loads almost never. If you are shipping weight, the floor decides what can come at all, and it is also what settles whether to ship your own property or rent in the market.

The variation that costs the most is inside one building rather than between cities. In Houston, one show prices a two-story exhibit at 13.00 dollars per square foot of the whole booth while another bans multi-story exhibits twice in the same halls. In Philadelphia, three shows contradict themselves rather than each other, one of them across three manuals for three exhibitor populations at a single event. In San Antonio, six shows share one building and four of them will not tell an exhibitor the height at all. In Detroit, four organizers do not agree on what kind of thing a booth rule is. One governs by easements measured inward from the aisles. One sets a flat 10-foot cap liftable by permission. One treats its rules as confidential, and one has published none. The building is the constant. The rules are not.

And a single published height figure is not always a limit. Two shows here publish a single height figure that marks the point at which you must submit drawings rather than the point at which you must stop building. One is 10 feet, in two of the Philadelphia auto show’s three manuals. The other is eight feet of pipe and drape, at a San Antonio toxicology meeting. Treating either as a cap means designing a smaller booth than the show allows.

Before a design goes to production in any of these markets, do four things. Get the hall, not just the building, because Detroit, Phoenix, Philadelphia and Washington all change the answer by hall. Get the floor load in writing from show management wherever the building does not publish one, which is five of these fourteen. Get the governing figure in writing wherever a document contradicts itself, and name the section you are asking about. And check the year and the cover on every document you are working from, because a label, a filename and a download path are not an edition.

Frequently asked questions

Does the convention center set the booth height, or does the show?

Almost always the show. Of the fourteen buildings across these ten markets, only two set a height of their own. The Pennsylvania Convention Center publishes no general limit and allows two stories and 30 feet for covered and multi-level exhibits. Huntington Place in Detroit publishes two different answers on two of its own current pages, 22 feet in its exhibit hall guidelines and 25, 19 or 15 feet by hall on its fire department page, and neither claims to replace the other. Everywhere else the show decides.

I am shipping heavy equipment. Which hall should I ask for?

Ask for it by name, because the floor load spread across these ten markets is a factor of nearly seven. Four halls of the Houston convention center are rated at 1,000 pounds per square foot, Detroit’s Hall E at 650, the Phoenix South Building at 600, and parts of two Detroit halls at 220. Five of the fourteen buildings publish no figure at all. Three places are worth asking for by name: the 89,145 square foot heavy load area across Halls H and I in New Orleans, Hall E in Detroit, and the South Building in Phoenix. In each case that hall is not the one a planner would have picked for anything else.

My show publishes one height figure. Is that the limit?

Not always. Read whether the figure is attached to a prohibition or to a submission. The Philadelphia auto show’s vendor manuals say displays over 10 feet must be approved in advance, and no manual states a height at which approval is refused. A San Antonio toxicology meeting’s only height figure is the eight feet of pipe and drape above which drawings must be submitted. Both numbers start a conversation rather than close one, and reading them as caps builds you a smaller booth than the show allows.

How can I tell whether the rules document I was sent is really the show’s own?

Check the cover, the year and the voice, in that order. One show here links a file from its own exhibitor service center, labeled as its 2026 rules and served from a 2026 path. The file’s own title abbreviates 2024, its content describes the convention center in the city the show has just left, and its first heading is the industry template’s. Nothing about the link said so. The document’s first page did.

My show says its rules are the industry association’s display guidelines. Is that enough to design from?

No, because they are not all citing the same document. Two cite the 2023 North American Update, one links the 2019 edition, and four name no year at all. A figure attributed to the guidelines without an edition year is not a citation. If your show delegates its rules that way, ask for the edition year in the same email as the figure, and ask whether the show amends it, because several of them do without saying so prominently.

Do I need an engineer for a two-story booth?

In almost all of them, and the authority differs enough to change your schedule. Phoenix treats a multi-level booth as a structure, requires a building permit and an inspection, and routes approval to the city with documents stamped by an Arizona licensed structural engineer. San Antonio requires a Texas registered design professional and gives the fire marshal 15 days, with construction prohibited until approval is issued. Detroit requires a Michigan-licensed engineer and sends plans to the event services manager and the fire marshal. New Orleans wants plans 60 days before move-in with an engineer’s stamp on the occupant load, plus a special event application whose fee is based on net square footage. Washington wants them 90 days before installation, sealed by a licensed structural engineer or architect. The engineering is the easy part. The queue is not.

What can my own staff do without hiring labor?

It depends on the building, and Philadelphia publishes the most generous answer of the ten. Full-time employees may set up and dismantle a booth of any size, use their own power tools and ladders up to 6 feet, hang graphics, install floor coverings and install non-rented equipment. Two limits decide whether that helps: the freedoms lapse the moment an exhibitor-appointed contractor is hired for the build, and the six-foot ladder is the practical ceiling, since hoists are barred and heavy objects need riggers. New Orleans sits at the other end, where freight moves through the official general contractor with no exceptions and the building provides no carts, dollies, pallet jacks or labor.

How far ahead do I need approval for a hanging sign?

The deadline belongs to the show, and here it runs from two weeks to several months. One San Antonio show requires submission at least two months before your assigned freight arrival date, which is earlier than it sounds, because freight arrives before you do. A Philadelphia architecture conference sets March 18 for a May show. A hematology meeting in New Orleans wants island renderings in mid-October for a December show. Ask for the date at the same time you ask whether a sign is permitted at all.

Can I reuse the same hanging sign at another show in the same building?

Often not, and New Orleans is the clearest case. Five shows at the Ernest N. Morial Convention Center give five different answers. One permits signs at unlimited height in four of its five booth types. One allows 20 feet to the top in islands and peninsulas and bans them in linear booths. One allows 20 feet to the top in islands only, and will let a sign cross an aisle for a fee. One does not mention the subject anywhere. One supplies the sign itself and does not permit changes. A sign built for one of those shows and carried to another in the same halls is a sign you will not hang.

Which of these markets is easiest to plan from published information?

On the building side, Phoenix and Minneapolis. Phoenix publishes a ceiling, a floor load and a rigging limit for every space. Minneapolis publishes a ceiling and a floor load for every space and names its measurement type, a clear height to the lowest truss, which few buildings do. Philadelphia and New Orleans come next, because one building holds the whole calendar and each publishes its own figures. The hardest is Washington, where four of five shows publish no booth height and four of five publish no hanging sign rule.

Is any of these venues under construction before my 2027 show?

Two things. Louisville takes delivery of a new 350,000 square foot facility at the Kentucky Exposition Center at the end of 2026, then begins a 213 million dollar redevelopment of the West Wing, West Hall and Pavilion, which the agency says will take 18 to 24 months with no completion date announced. And the semiconductor show moving to Phoenix with its 2027 edition is in its first year in that building, so every rules document tied to it from 2026 or earlier was written for a hall in another state.

Can the convention center be closed during my move-in?

Yes, and the closure is usually published long before the booth rules are. One Phoenix show’s 2027 schedule marks Easter Sunday, March 28, as a day when the convention center is closed and no exhibitor move-in, set-up or freight is received. It turns a four-day move-in into three. The same trap hides in deadline pairs: a city fire marshal may want documents 15 days out while your show wants drawings two months out, and you are bound by whichever comes first.
