Basketball uses a stop clock, so 40 or 48 minutes of playing time does not equal 40 or 48 minutes in the venue. Fouls, free throws, time-outs, substitutions, reviews and quarter breaks extend the event.
The governing rules matter when planning transport, venue hire or recording capacity. Youth leagues can shorten periods further and may use a running clock for parts of the game.

| FIBA | 4 × 10 minutes (40 total) | 5 minutes |
| NCAA men | 2 × 20 minutes (40 total) | 5 minutes |
| NCAA women | 4 × 10 minutes (40 total) | 5 minutes |

How long should you allow in real time?
A senior game commonly occupies roughly 90 minutes to more than two hours, depending on the level, time-out rules, media breaks and number of stoppages. Televised NBA games are usually at the longer end. A close finish with fouls and reviews can add considerable time to the final minute of game clock.
If you are filming, begin with a fully charged phone and enough storage for warm-ups, regulation and possible overtime. Do not size the recording only to the official playing minutes.
What stops the clock?
- An official's whistle for a foul or violation.
- Time-outs and certain substitutions.
- The ball becoming dead under the competition's timing rules.
- Official review or equipment problems.
- The end of each period; overtime is added when the score is tied.

Frequently asked questions
Why does an NBA game last longer than 48 minutes?
The 48 minutes count only live regulation play. Fouls, time-outs, breaks, reviews and other dead-ball periods extend real time.
How long is overtime in basketball?
NBA, FIBA and NCAA overtime periods are five minutes. More periods are played until the tie is broken.
How long is a youth basketball game?
It varies by league and age. Many youth competitions use shorter periods or a running clock.
