Alexander Stadium had 18,000 permanent seats before its optional expansion for major events during Birmingham 2026.
The stadium’s redevelopment created two permanent stands with a combined seating capacity of 18,000. Organisers could add temporary capacity for major events, giving the venue a larger configuration when required. The permanent figure describes the built-in seating rather than the maximum event arrangement.
This distinction matters because stadium capacities are often reported in more than one way. A venue can have a permanent everyday capacity and a higher temporary capacity for a championship, concert or other major event.
Alexander Stadium’s redevelopment took place between 2019 and 2022. It supported the athletics programme at the 2022 Commonwealth Games and later prepared the venue for the 2026 European Athletics Championships.
