As many Managers, we do not understand why we have build stadiums with 21,000 seats (for example me at my level 2) and there are only 2,500 spectators at each games. It's just limited to the league level...
What is the capacity of the stadium at the different levels?
There is a specific rule on the maximum amount of supporters a Manager can have in a home game. This quantity is limited by the Manager's level and cannot be exceeded, regardless of the stadium's capacity.
Here are the maximum capacities of a stadium according to the level of Manager:
Lvl. 1 - 800
Lvl. 2 - 2,500
Lvl. 3 - 6,000
Lvl. 4 - 11,500
Lvl. 5 - 19,000
Lvl. 6 - 28,000
Lvl. 7 - 40,000
Lvl. 8 - 53,500
Lvl. 9 - 69,000
Lvl. 10 - 86,500
Lvl. 11 - 106,000
Lvl. 12 - 127,500
Lvl. 13 - 151,000
Lvl. 14 - 176,500
