15 Biggest Indoor Arenas in the World by Capacity

Philippine Arena is the biggest indoor arena in the world. Its builder lists 51,000 seats and a 55,000 maximum configuration, more than twice the capacity of the next conventional arena in the ranking.

That answer depends on using “arena” carefully. A roofed 70,000-seat football stadium is indoors, but it is not an arena in the same architectural category. An unfinished building is not yet a usable arena. This list therefore ranks existing, purpose-built indoor arena venues by maximum seated capacity.

World’s largest indoor arenas ranked

Capacities are configuration-dependent. The figures below are the largest documented seated arena setup, not a promise that every basketball, hockey or concert event can sell that many seats.

Rank	Arena	City	Country	Max seated capacity	Opened
1	Philippine Arena	Bulacan	Philippines	Up to 55,000	2014
2	Mineirinho	Belo Horizonte	Brazil	About 25,000	1980
3=	GMO Arena Saitama	Saitama	Japan	22,500 arena mode	2000
3=	SKA Arena	St. Petersburg	Russia	About 22,500	2023

Ties reflect the precision available. Calling one 22,500-seat venue larger because a source adds a few temporary chairs would create a false distinction.

1. Philippine Arena: up to 55,000

Philippine Arena sits in Ciudad de Victoria, north of Manila. Hanwha, its design-build contractor, reports 51,000 permanent seats and a maximum capacity of 55,000. Guinness lists 51,929 for the record it certified when the building opened.

The bowl is one-sided, with a stage and focal area at one end rather than seats wrapping evenly around a center court. That design suits worship gatherings, concerts and large ceremonies while still allowing basketball and other sports. The roof covers nearly 36,000 square metres without internal columns blocking views.

Its scale creates a category of its own. The gap between Philippine Arena and Mineirinho is roughly 30,000 seats—larger than almost every arena below them.

2. Mineirinho: about 25,000

Mineirinho stands beside the Mineirão football stadium in Belo Horizonte. The indoor venue has hosted volleyball, futsal, basketball and concerts, with arena directories commonly listing about 25,000.

Configuration and renovation history make its figure less clean than Philippine Arena’s. It remains useful as the second entry under a broad maximum-capacity method, but event-specific plans may be lower. Readers buying tickets should use the promoter’s seating chart rather than a building maximum.

3. GMO Arena Saitama: 22,500 in arena mode

The venue long known as Saitama Super Arena uses a 15,000-ton movable block to change its interior volume. Its official main-arena layouts hold roughly 19,000 to 22,500 for indoor sports and about 22,000 for a centre-stage concert.

It can expand into a “stadium mode” holding up to 37,000 for concerts and trade shows. This ranking uses 22,500 because that is its arena configuration; using 37,000 would compare a transformed stadium floor with conventional arena bowls.

There is also a current-status caveat. The venue closed on 13 January 2026 for major renovation expected to last up to 18 months. The building still exists in the capacity ranking but is not hosting main-arena events during that closure.

4. SKA Arena: about 22,500

SKA Arena opened in St. Petersburg in 2023 as a modern ice-hockey venue. Its hockey configuration is generally listed around 21,500, with larger seated arrangements reaching roughly 22,500. Venue scale and player compensation are separate comparisons; see the current highest-paid NHL players for the 2026-27 cap-hit ranking.

That difference illustrates a recurring problem: an ice rink removes floor seats, while a concert or fighting-sport setup can add them. The table uses the maximum documented seated arena arrangement, not hockey-only capacity.

5. Arena Ciudad de México: 22,300

Mexico’s national cultural venue database lists Arena CDMX at 22,300. The building opened in 2012 with 126 suites, a large exterior LED facade and a column-free oval bowl.

At that figure it is the largest purpose-built arena in North America under this method, just ahead of Bell Centre and KFC Yum! Center. It hosts concerts, basketball, combat sports and family shows rather than relying on one permanent major-league tenant.

6-10. The 21,000-to-22,114 group

Five venues are separated by only 436 seats:

• Bell Centre can reach 22,114 and is the largest NHL home by its highest arena setup. Hockey seating is lower because the rink and sightlines consume floor space.
• KFC Yum! Center lists 22,090 for basketball and is the University of Louisville’s downtown home.
• Greensboro Coliseum can approach 22,000 in its largest setup and remains unusually large for a building opened in 1959.
• Dean Smith Center seats 21,750 for North Carolina basketball, one of the largest fixed college-basketball crowds.
• Food City Center in Knoxville lists 21,678 and is another college venue larger than every NBA building.

The concentration of US college arenas near the top is not accidental. Campus basketball can fill buildings that host 15 to 20 home dates without the premium-space tradeoffs common in newer professional venues.

11-15. Manchester and the large North American arenas

AO Arena in Manchester anchors the next group at about 21,000. United Center follows at 20,917 for basketball, making it the largest NBA arena by listed basketball seats.

Amerant Bank Arena, Tacoma Dome, Benchmark International Arena and Canadian Tire Centre fill out the list. Tacoma is architecturally different—a cable-supported wooden dome with flexible floor layouts—while the others are conventional professional ice-hockey and event bowls.

At this end of the table, capacity changes by event. A stage can close thousands of seats behind it; a centre-stage show can reopen those sections and add floor chairs.

Why the KJC King Dome is not number one

The KJC King Dome in Davao has been publicized with a planned capacity of 75,000. If it opens at that size and meets the same enclosed-arena definition, it would pass Philippine Arena by 20,000.

As of August 2026, it remains an unfinished project without an operating capacity. Ranking a rendering and target alongside buildings that have passed occupancy and hosted crowds would mislead readers. This page will add it only after opening and confirmation of its usable seated configuration.

Arena, dome and indoor stadium are not synonyms

Arenas normally wrap steep seating around a court, rink or performance floor. Indoor stadiums enclose a full football, rugby or baseball field. The distinction matters because venues such as Caesars Superdome, AT&T Stadium and Paris La Défense Arena can seat far more than 55,000 in some layouts.

Building type	Typical floor	Example	Included here?
Indoor arena	Court, rink, concert floor	Philippine Arena	Yes
Convertible arena/stadium	Movable arena blocks	GMO Arena Saitama	Arena mode only
Roofed field stadium	Full football/rugby field	Caesars Superdome	No
Unfinished arena	Planned but not operational	KJC King Dome	No
