NBA: 12–15 active players per game, with unlimited substitutions.
College: Typically 10–13 scholarship players; substitutions allowed during stoppages.
International: FIBA allows 12-player rosters with 5 active substitutions per game.

Coaches strategically rotate players to manage fatigue and match up against opponents.
