How many players are on a basketball team?
On the Court
In a standard basketball game, each team fields five players on the court: typically two guards, two forwards, and one center, though modern positions are more fluid. The game is played 5-on-5.
This is true for the NBA, WNBA, NCAA, FIBA, and most other organized leagues. Variations like 3-on-3 basketball exist (e.g., in the Olympics), but the traditional game is 5-on-5.
Roster Size
While only five play at once, teams have larger rosters. In the NBA, teams can have up to 15 players under standard contracts, with a maximum of 13 active for a game (though this can vary with two-way contracts).
In the WNBA, rosters are typically 12 players. In college, NCAA Division I teams can have up to 15 players on scholarship, but only five on the court. FIBA rules allow up to 12 players on a roster for international competitions.
Substitutions
Substitutions are unlimited in basketball, but they can only occur during dead balls (when the clock is stopped). Players can enter and leave the game multiple times.
A team must have at least five players to start a game. If a team has fewer than five due to fouls or injuries, they may have to forfeit or play short-handed, depending on the league's rules.
Common mistakes
- Confusing roster size with on-court players—only five play at a time.
- Thinking all leagues have the same roster limits—they vary (NBA 15, WNBA 12, FIBA 12).
- Believing a team can play with fewer than five without penalty—most leagues require five to continue.
