What Is the Biggest NBA Arena?

United Center, the home of the Chicago Bulls (the fourth-winningest NBA franchise in history), is the biggest NBA arena in the 2023-24 season as it houses a capacity of 20,917. It’s one of four arenas in the league which can accommodate over 20,000 fans.

The other three arenas with 20,000-plus seats are the Wells Fargo Center in Philadelphia, Capital One Arena in Washington and Little Caesars Arena in Detroit. Nine arenas can accommodate 19,000-plus fans and the other 16 arenas have a capacity between 18,000-plus and 16,000-plus.

The newest NBA arena will open in 2024, as the Los Angeles Clippers will have a new home, Intuit Dome. This marks the separation from its city rival, the Los Angeles Lakers, with whom they have shared the home floor since joining the league. Intuit Dome will have an estimated capacity of 18,000.

18,790 is the average capacity of all 29 NBA arenas.
