How Many Quarters in Basketball?
Quick answer: 4 quarters in an NBA game. Keep reading for the full breakdown.
An NBA basketball game consists of 4 quarters, each lasting 12 minutes of game clock time. The total regulation playing time is 48 minutes, though the actual elapsed time from tip-off to final buzzer averages about 2 hours and 15 minutes due to timeouts, fouls, halftime and commercial breaks.
College basketball (NCAA) uses a different format: 2 halves of 20 minutes each (40 minutes total). FIBA international rules split the game into 4 quarters of 10 minutes each (40 minutes total). High school basketball uses 4 quarters of 8 minutes each (32 minutes total). The NBA stands alone among major basketball organizations in using 12-minute quarters.
Overtime periods in the NBA last 5 minutes. There is no limit to the number of overtime periods, and games occasionally go to double, triple or even quadruple overtime. The longest NBA game in history was a 1951 contest between Indianapolis and Rochester that required 6 overtime periods.

| WNBA | 4 quarters | 10 min | 40 min | 5 min |
| NCAA | 2 halves | 20 min | 40 min | 5 min |

⏱️ Why Games Take So Long
A 48-minute NBA game takes over 2 hours because of mandatory TV timeouts (4 per quarter), team timeouts (7 per team per game), free throws (average 44 per game combined), referee reviews and halftime (20 minutes). The stop-start nature of basketball means roughly 60% of the broadcast is non-playing time, which is why the NBA has experimented with reducing timeouts and shortening breaks to improve pace of play.
