The biggest and smallest NBA arenas
The United Center in Chicago, home of the Chicago Bulls, is the largest NBA arena by listed basketball capacity, at 20,917 seats. The smallest is the Smoothie King Center in New Orleans, home of the Pelicans, at 16,867. Every other arena in the league falls between those two figures, and most sit between 17,500 and 19,500.
Unlike the NFL, where two pairs of teams share stadiums, each of the 30 NBA teams has its own home arena. The newest is Intuit Dome in Inglewood, California, which the LA Clippers opened in August 2024. The oldest in use is Madison Square Garden, which opened in 1968 and was rebuilt inside its original structure from 2010 to 2013.

Why capacity figures disagree
Published capacities for the same arena can differ by a few hundred seats, and both numbers can be correct.
- Basketball vs. hockey: arenas that host both sports seat more for basketball, because the court is smaller than a rink and courtside rows fit closer. Scotiabank Arena lists 19,800 for basketball and about 18,800 for hockey.
- Standing room and premium changes: teams add or remove courtside rows, lofts and standing areas between seasons, so the official figure moves.
- Different sources, different dates: a team media guide, the arena's own site and Wikipedia may be updated at different times. The Good Seats Intuit Dome page lists 18,300 for basketball, while Wikipedia's league list shows 18,000.
For a sold-out game, the practical difference is small. What matters to a ticket buyer is how the seats are arranged: how many rows are in the lower bowl, how steep the upper level is, and how far the top row sits from the court.
Arenas on the way
As of November 2026, Wikipedia lists one NBA arena under construction and several proposed. A new arena for the Oklahoma City Thunder is being built with a planned 2028 opening. New buildings have been proposed for the Philadelphia 76ers in South Philadelphia, the Dallas Mavericks and the San Antonio Spurs, with target dates from 2030 to 2032. Capacities for those buildings had not been set. Plans like these change, so check the team's announcements for current status.
What arena size means when you buy tickets
A larger arena does not automatically mean easier tickets. Demand depends on the team, the opponent and the night of the week, and a 17,000-seat arena with a contender can be harder to get into than a 20,000-seat arena with a rebuilding team. Size mostly changes the shape of the upper level. Bigger buildings tend to add rows or a third tier, which pushes the top seats farther from the court.
The best basketball seats follow the same pattern in every arena: sideline sections in the lower bowl a few rows up, then the corners, then the center of the upper level. The Best Seats at a Basketball Game explains how to choose, and What Is Lower Bowl Seating? covers how levels are named.
