How Long Does a Basketball Game Last?

If you’re wondering about the how long a basketball games lasts, the simple answer is that the length depends on the type of game. However, probably the most viewed games are the NBA. These games take place in four quarters of 12 minutes each so the entire game is 48 minutes.

In general, there is not one standard time frame for the basketball games. Depending on the level including high school and professional basketball, the game length can vary. Additionally, since the overtime is a possibility, the game may last longer than the standard period of time.

How long does NBA Basketball Games last?


Like mentioned previously, an NBA game has a standard game time of 48 minutes. However, halftime gives both teams a 15 minute break time to allow some rest time in the middle of the game. Each overtime period in the NBA will last five minutes.

While the actual game time is 48 minutes, you should be prepared to stay for a longer period of time if viewing a game. The average amount of time for the NBA lasts about 2-3 hours. This will include not only the time playing but also timeouts, replay reviews, halftime breaks, and other stoppages. The average basketball game lasts about two and a half hours from the beginning to end of the game.

College Basketball Games Length

Although some players go from college to the NBA, the rules of the game are not the same. NCAA men’s games are only divided into halves. Both halves last 20 minutes long for a total game time of 40 minutes.

Just like the NBA, the overtime periods are five minutes long. The NCAA women’s college games follow a slightly different timeframe though. Their total game time is also 40 minutes but they play in four ten-minute quarters. This is the same as the WNBA. Regardless of the way that the time is split up, both games usually are about two hours in length.

High-School Basketball Game Length

This is an area where there is not one standard time. The game is split into quarters and most teams will play eight-minute quarters. However, there may be some variations in each state.

Generally speaking, the game tends to get longer and played for longer periods of time as players advance from high school to professional teams. This is likely due to increased stamina of the players over time. Audience interest will also probably increase for college and professional teams over the lower levels.

The Shot Clock and Basketball

Although there are standard times set for quarters and halves in basketball, this does not mean that the teams don’t still have other effects on the game. One of the biggest changes that affected the length of the average basketball game was the shot clock.

In 1954, Syracuse National owner and general manager decided to implement a 24-second clock. Tired of games that were low action, the result of this change was that the games became faster and higher-scoring. Based on their results, the NBA decided to officially adopt the shot clock for the following season.

Some ardent fans said that the shot clock revolutionized the game. It certainly changed the pace of basketball as players were forced to play more rapidly and avoid holding onto the ball for an extended period of time. This led to more points scored and also increased attendance at the games. Regardless of the effects, this was a hugely favourable move.

The shot clock is simply a timing mechanism used to speed up the game. Each team must attempt to shoot the ball before the shot clock expires. If they fail to do this, then they’ll lose possession of their ball. In the NBA, they use a 24-second clock. It will reset to 14 seconds after a player has an offensive rebound or a free throw that hits the rim.

The NCAA uses only a 30-second clock for both the men and women’s matches. They had began with a 45-second clock in the 1980s but reduced it to 35 minutes before finally setting to 30 seconds.

Timeouts in Basketball

As anyone who has ever been to a game probably knows, the timeouts won’t increase the length of the actual game play but can significantly add to the length of the games. The game clock is known for being stopped frequently in the NBA. In response to this, the league has tried to reduce how many timeouts any team can call during the game. During the 2017-2018 season, the NBA only allowed seven timeouts to be called during a game. Every team is also only allowed to have two outs in the final three minutes. This is a change from the previous rule which allowed for three outs in the last two minutes.

A timeout will only last 75 seconds so teams have to work rapidly during this period. The NBA previously had 100-second timeouts and even would have 20 second timeouts before changing their rules. Since the 20-second timeouts usually led to periods that were closer to 60 minutes, they changed their process.

The NCAA follows a slightly different process. They allow for three 30-second timeouts for each game. Two of these can be completed in the second half. Additionally, teams will have one 60-second timeout which they can call at any time in the game. Similarly, high school games use a similar process as colleges.

Longer Basketball Games

Although understanding the general time frames provides a good idea of how long to expect, the question of how long does a basketball game last also depends on the score. One game that was played in 1951 between the Indianapolis Olympians and the Rochester Royals lasted for 78 minutes. The teams battled it out over six overtimes. The Olympians eventually won but the victory took much longer than desired.

In general, basketball games are a fun activity that take place in less than hour although the actual game will be 2-3 hours in general. Teams have changed the rules over time to encourage fast games with active and motivated players. Viewers can see these changes at the average game today.
