List of indoor arenas by capacity


The following is a list of arenas ordered by seating capacity, which is the maximum number of seated spectators the arena can accommodate for a sports event. Only the capacity for indoor sports, such as basketball, ice hockey, and volleyball, are included. Currently all arenas with a capacity of 15,000 or more are included.
Venues are only included if they are designed primarily for sports traditionally held indoors. Venues built for field sports that also host indoor events are not included. Such unincluded venues include:
Some of the above venues have hosted some of the largest crowds in history for indoor sports. The Caesars Superdome, for example, regularly seats more than 70,000 for basketball games. The largest confirmed attendance for a basketball game was at AT&T Stadium for the 2010 [NBA All-Star Game].
By contrast, Saitama Super Arena in the Japanese city of the same name is included because it was built primarily for indoor sports, although it can be configured to host field sports.
