How Long Are WNBA Games?

A WNBA game lasts 40 minutes of playing time, divided into four 10-minute quarters, under the league’s official rules. That makes it eight minutes shorter than an NBA game, which uses four 12-minute quarters for 48 minutes of play.

Of course, “40 minutes of play” and “how long you sit watching” are two different things. Because the clock stops constantly, a WNBA broadcast usually fills about two hours. Here is exactly how the game is structured, why it is shorter than the NBA’s, and how the clock actually runs.

The basic structure: four 10-minute quarters

The WNBA plays four quarters of 10 minutes each, with a halftime break after the second quarter and shorter breaks between the other quarters. Teams change baskets at halftime. Add the four quarters together and you get 40 minutes of regulation basketball.

That 40-minute figure is the number most fans want. It is the actual amount of time the game clock runs during normal play, assuming the game is not tied and does not go to overtime.

Why a WNBA game is shorter than an NBA game

The WNBA and NBA share the same four-quarter framework, but the quarter length is different. This one difference accounts for the entire gap in game length.

Element	WNBA	NBA
Quarters	4	4
Minutes per quarter	10	12
Regulation playing time	40 minutes	48 minutes
Overtime period length	5 minutes	5 minutes
Shot clock	24 seconds	24 seconds
Halftime	After 2nd quarter	After 2nd quarter

Reading across the table, everything matches except the minutes per quarter. The WNBA’s 10-minute quarters put it in line with international basketball under FIBA rules and with U.S. college basketball’s overall playing time, rather than with the NBA’s longer 48-minute game. The shot clock in basketball is the same 24 seconds in both leagues, so the pace of each possession is identical, only the total playing time differs.

Playing time vs. real time

If the clock only ran for 40 minutes, a game would be over in well under an hour. In practice a WNBA game takes roughly two hours of real time, because the game clock is a “stopped clock,” it pauses far more often than it runs.

The clock stops for:

• Fouls and the free throws that follow them
• Timeouts called by coaches, plus mandatory media timeouts
• The ball going out of bounds and other dead-ball situations
• Replay reviews of close calls
• The end of each quarter, with breaks between periods and a longer halftime

All of these stoppages stretch 40 minutes of basketball across about two hours on your screen. A tightly officiated, foul-heavy game with lots of late timeouts runs longer; a clean game with few whistles finishes quicker.

What happens if the game is tied

Regulation is 40 minutes, but a tie does not end in a draw. If the score is level at the final buzzer, the WNBA plays a five-minute overtime period. Whoever leads when that period ends wins. If the teams are still tied after five minutes, they play another five-minute overtime, and they keep going until someone is ahead at the buzzer.

Each overtime adds five minutes of playing time and, with its own stoppages, another chunk of real time. Multiple-overtime games are rare but do happen, and they are among the most dramatic finishes the league produces.

How the WNBA compares to other basketball formats

The 40-minute game is not unusual, it is actually the NBA that is the outlier. FIBA international competitions, including the Olympics and World Cup, use four 10-minute quarters. Most other professional and international leagues around the world follow the same 40-minute standard. So a WNBA game is the same length as an Olympic basketball game, and eight minutes shorter than an NBA game.

If you want a sense of how basketball’s timing choices compare to other sports, our look at how long a soccer game lasts shows a very different model, a running clock rather than a stopped one.

The short version

A WNBA game is 40 minutes of play, four 10-minute quarters, which is eight minutes shorter than the NBA’s 48-minute game. Thanks to the stopped clock, a typical WNBA game takes about two hours in real time, and if the score is tied after regulation, teams play five-minute overtime periods until one side leads at the buzzer.
