How Many Quarters Are in a Basketball Game? NBA, NCAA, and FIBA Compared
Basketball game timing can look simple on the surface—but every major organization structures its periods differently. From the NBA’s four-quarter format to NCAA’s half-versus-quarter debate and FIBA’s international standards, these differences affect gameplay, pacing, and strategy. Here’s a complete comparison to understand how each league runs its games.

Whether you're watching the NBA, NCAA college games, or international FIBA competitions, the number of quarters—or even the presence of quarters—can vary significantly. This guide breaks down how many quarters each organization uses, how long those periods last, and why the game structure matters for players, coaches, and fans.

NBA Game Format
Number of Quarters in the NBA
An NBA game is divided into four quarters, each forming one segment of regulation play.
Quarter Length and Break Durations
● Each quarter lasts 12 minutes, making regulation time a total of 48 minutes.
● Short breaks occur between the 1st–2nd and 3rd–4th quarters, typically around 130 seconds.
Halftime Regulations
Halftime follows the second quarter and lasts 15 minutes, allowing teams to rest and coaches to adjust game plans.
Overtime Length and Rules
If the score is tied after four quarters:
● Overtime lasts 5 minutes.
● Teams receive additional timeouts according to league rules.
● Overtime periods repeat until a winner is determined.
NCAA Game Format
Men’s College Basketball (Two-Half Structure)
Unlike most leagues, NCAA men’s basketball uses halves instead of quarters:
● Two halves of 20 minutes each.
● Total regulation time: 40 minutes.
Women’s College Basketball (Four-Quarter Structure)
NCAA women’s basketball follows a four-quarter format, similar to international play:
● Four quarters of 10 minutes each.
Media Timeouts and Broadcast Requirements
NCAA games include structured media timeouts:
● Occur around the first dead ball after the 16-, 12-, 8-, and 4-minute marks in each half (men) or quarter (women).
● Timeouts ensure consistent broadcast opportunities and break rhythm more frequently than in the NBA or FIBA.
