Under the NBA rules, a quarter is officially 12 minutes, while the International Basketball Federation (FIBA) uses a 10 minute quarter. NCAA matches follow a two-half format that takes 20 minutes each.
The length of quarters in basketball depends largely on the league being played. In men’s college basketball in the US, 20-minute halves are used instead of quarters. In most high school leagues across the country, quarters are eight minutes in length but may vary slightly in some states.
The quarters of an NBA game are 12 minutes long, and there are also breaks between the first and second quarters and the third and fourth quarters, both consisting of two minutes long. Between the second and third quarter is halftime, which is 15 minutes for regular-season games.
A basketball game organized by International Basketball Federation, consists of 4 quarters (periods) of 10 minutes with 2 minutes gap between each quarter. The allotted time of a NBA game is 48 minutes, split into 4 quarters of 12 minutes but normally it takes a much longer time to finish an NBA game as there are so many interruptions and delays involve in a game.
A quarter in basketball refers to the period of time in one section of a basketball game. A NBA game is split into four, 12 minute periods that are referred to as quarters. The game clock reads how much time is left in every given quarter, starting at 12 and running all the way to zero.
The game lasts for 32 minutes; however, the overall amount of time, including breathers, fouls, and clock pauses, lets the game run for 1 hour and a half. Much as it is in NBA play, there are four quarters in high school hoops while they are a little shorter. Each of the four quarters runs for eight minutes.
The most common game length is four 8-minute quarters. While that may seem like a large amount of time for young basketball players, most leagues run the clock continuously, with the only stoppage being from timeouts and the end of the quarter. There’s also a quick five-minute break after the second quarter for half time.
Taking the foundation of the basketball rules seen in college prior to the birth of the league, the NBA decided that 12 minute quarters was the perfect amount of time for a basketball game to last just over 2 hours. They determined this was the ideal amount of time for a paying spectator to enjoy a professional basketball game.
