"—" means the venue doesn't publish that figure in a comparable form. Hotel-based venues in Las Vegas (The Venetian and Mandalay Bay) are included because they host many of the largest trade shows on the continent. Mandalay Bay's figures are MGM Resorts' own round numbers as reported by WorldAtlas.
United States highlights
Four US venues report more than 1.5 million sq ft of exhibit space: McCormick Place, the Las Vegas Convention Center, the Orange County Convention Center and the Georgia World Congress Center. Orlando's Orange County Convention Center splits its 2.05 million sq ft across the West Building and the North-South Building, and its Valencia Ballroom is 62,182 sq ft.
New Orleans' Morial Convention Center advertises 1.1 million sq ft of prime exhibit space on one level, which it describes as America's largest contiguous-space exhibit hall. For the biggest ballrooms, look at the Las Vegas resort venues, the 80,000 sq ft Bluebird Ballroom in Denver and the 55,400 sq ft ballroom in Philadelphia.
Canada highlights
Toronto has two of Canada's largest venues: Enercare Centre at Exhibition Place, built for large trade and consumer shows, and the Metro Toronto Convention Centre downtown, with 442,000 sq ft of exhibit space and 77 meeting rooms. Montréal's Palais des congrès offers 396,785 sq ft of exhibition space and 113 rooms and venues. The Vancouver Convention Centre lists 311,500 sq ft of exhibit space within 466,500 sq ft of combined meeting, exhibition, ballroom and plenary space across its East and West buildings, and calls its ballroom Canada's largest waterfront ballroom.
Mexico highlights
Expo Guadalajara reports 119,000 square meters of construction and capacity for 60,000 people. In Mexico City, Centro Citibanamex has 34,000 square meters of column-free exhibition space that divides into four halls, plus 25 multipurpose rooms. Monterrey's Cintermex has a roughly 198,000 sq ft exhibition hall that divides into six halls. If you sell into Mexico or Latin America, see our Latin America public sector events.
What the numbers mean
- Exhibit space (prime exhibit space): the exhibit hall floor that can be sold for booths. It's the standard way the industry ranks venue size.
- Total space: exhibit halls plus meeting rooms, ballrooms, lobbies and support areas. It's usually two to three times the exhibit figure, which is why rankings that use it look different.
- Contiguous space: the largest area you can use as one uninterrupted floor. It matters most for very large shows.
- Meeting rooms: venues count differently. Some count permanent rooms; others count every possible breakout created by moving walls.
- Largest ballroom: the biggest carpeted room for general sessions, keynotes and banquets.
- Airports: the main commercial airports serving the city, not necessarily the closest.
Exhibiting at a big venue? Plan meetings before you go
Large venues hold large shows, and large shows are crowded. The exhibitors who get the most from them book meetings with target accounts before the event instead of waiting for booth traffic. Kensington Sales Group's SDRs run pre-show outreach and post-show follow-up for companies that sell to government agencies, utilities, schools and healthcare systems. See event prospecting and our list of the top 100 public sector conferences.
How we built this list
We started from industry rankings of North American venues by exhibit space, then checked each figure against the venue's own website, fact sheet or floor plan booklet, or its official tourism bureau. Where a venue doesn't publish a figure, we used an industry directory (EXHIBITOR Magazine's Centers of Excellence listings or Trade Show Executive) and linked it. Figures were checked on November 13, 2026. Venues expand and remeasure, so confirm current specifications with the venue before you book.
