10 Largest Convention Centers in the US

I’m going to do something a little unconventional (Get it???? God I hate me too) and put this list in reverse order, starting with the smallest.

These 10 convention centers aren’t the only BIG ones in the country.

There’s the TCF Center in Detroit, Michigan (with 723,000 square feet of exhibit space), Mandalay Bay Resort & Casino in Las Vegas, and The Walter E. Washington Convention Center in Washington, D.C. that offer massive spaces for events, but these 10 are definitely where the biggest events are held.

Located in the Marina District, Gaslamp Quarter, the San Diego Convention Center is in a lot with 2,600,000 square feet of potential event space.

It was originally designed by Canadian architect Arthur Erickson as an open-air facility under the roof.

Right now, the convention center uses 600 thousand square feet of exhibition space indoors with popular features like the Sails Pavilion and the outdoor inclined elevator.

The San Diego Convention Center is expected to undergo more expansions in the future.

Its most popular annual event is definitely San Diego Comic-Con, but the place also hosts numerous political, business, and entertainment events year-round.

9. Anaheim Convention Center (Anaheim, CA)

Opened in 1967, the Anaheim Convention Center is now the largest convention center on the West Coast.

The entire place has undergone several expansions since it opened its doors and now has multiple spaces for exhibit halls, meeting rooms, the domed arena, an outdoor plaza, and more.

Many events have been held here, but none more famous than the D23 Expo, a biennial convention for Disney fans, first held in 2009, and all other subsequent D23 Expos.

  • NRG Astrodome is a multipurpose space that has welcomed sports, politics, and music events here.

NRG Center, which is the complex’s convention center actually has only 706,000 square feet of exhibit space, but the other 3 areas can also serve as convention areas when necessary.

The Venetian Expo opened in 1990 as “Sands Expo” as it was located behind the Sands Hotel.

When the hotel was later replaced by the Venetian, the convention center was renamed Venetian Expo as well.

The Venetian Expo is an attraction on its own thanks to its proximity to downtown Las Vegas, making it super-convenient for out-of-town attendees.

The expo boasts a 1,890-seat theater, a maximum banquet capacity of 1,260 people, and over a million square feet of meeting and event space.

The Las Vegas Convention Center (LVCC) has 16 exhibition halls, 144 meeting rooms, and two grand lobbies (with registration areas in West and Central halls).

Although the nearby Venetian is newer, many of the world’s most prominent meetings, trade shows and business conferences continue to call LVCC home year after year, thanks to the size, versatility, and amenities near the Vegas Strip.
