Convention centers - additional information

Typically convention centers are large buildings suitable for accommodating several thousand people for such events as conventions, trade shows, meetings, lectures and concerts, among other things. As of August 2016, McCormick Place in Chicago, Illinois was the largest convention center in the United States. At 2.6 million square feet, McCormick Place was half a million square feet bigger than the second largest center, Orange County Convention Center in Orlando, Florida.

In 2015, there were 255 convention centers in the U.S., covering just short of 75 million square feet. With a total of 22 establishments, California was the state with the largest number of convention centers, followed by Florida and Nevada. Florida, however, did not have largest amount of convention center space, this accolade went to Nevada, which had 6.15 million square feet of convention space as of June 2015. This is perhaps unsurprising as its most populous city, Las Vegas, is one of the leading cities for conventions, meetings and business in the U.S. In 2015, more than 21 thousand conventions were held in Las Vegas.

On a global scale, America’s largest convention center placed ninth. The largest convention center worldwide in 2015 was the Hannover Messegelände, or Hanover Fairground, at approximately five million square feet. The third largest center, also in Germany, was the Frankfurt Main Exhibition Grounds.
