As of October 2026, and how capacity is counted. An arena here is an indoor venue built for court or ice sports and concerts. Domed football and baseball stadiums such as the Caesars Superdome or Tokyo Dome are left to the stadium list, and so is Paris La Défense Arena, a roofed rugby stadium.^[26] Capacity depends on the setup, so the main ranking column is the largest figure the venue, its operator or a primary reference publishes for a standard layout, usually the concert or event setup with a standing floor where one is offered. The next column shows the seated capacity for the venue’s main sport where one is published. Record crowds and temporary arrangements are not used. Rows tied on capacity share a rank. The list stops at 14 because the figures below about 21,500 get too thin and contradictory to rank with confidence.^[26]

Softer figures, and who is not here. The KJC King Dome’s 75,000 and the Philippine Arena’s 55,000 are owner or press figures with no independent audit, and both buildings are religious-group projects that also host concerts and sport.^[1][2][3] Saitama’s 37,000 is the venue’s own “up to” stadium-layout figure; Wikipedia gives 36,500.^[5][6] The United Center, SKA Arena, Sinan Erdem Dome and Arena CDMX figures rest on Wikipedia or press rather than a current venue page.^{[12][17][18][19]} Left out: the Bell Centre in Montréal, listed at 20,962 for hockey (an older 22,114 basketball figure is out of date) and 15,000–19,200 for concerts;^[27] the Palacio de los Deportes in Mexico City, quoted anywhere from 17,800 to 26,000;^[29] Mineirinho in Belo Horizonte, shown as 25,000 on some lists but about 20,000 in Minas Gerais government material;^[28] and Rupp Arena, cut from 23,500 to about 20,500 in a 2019 renovation.^[22] Greensboro Coliseum was left out because sources split between 22,000 and 23,500.
