Seating capacity at Capital One Arena changes depending on the event you’re going to see. For Washington Capitals hockey games, the official capacity is around 18,506 fans, which creates a pretty energetic environment on game nights. For Wizards basketball games, that number goes up to about 20,356 people, making it one of the bigger NBA arenas. Concerts and touring shows often set up floor seating and special arrangements that push capacity even higher, typically near 20,000 or more depending on how the stage is placed. The arena’s layout and bowl design allow it to adapt to different event types, so you get a good view whether it’s sports or a show. Suites and club areas also add extra viewing options for fans who want a premium experience. Regardless of the event, it’s built to feel packed with energy and excitement all around you inside the venue.
