<P> Games are played in four quarters of 10 ( FIBA ) or 12 minutes ( NBA ) . College men 's games use two 20 - minute halves , college women 's games use 10 - minute quarters , and United States high school varsity games use 8 minute quarters . 15 minutes are allowed for a half - time break under FIBA , NBA , and NCAA rules and 10 minutes in United States high schools . Overtime periods are five minutes in length except for high school , which is four minutes in length . Teams exchange baskets for the second half . The time allowed is actual playing time ; the clock is stopped while the play is not active . Therefore , games generally take much longer to complete than the allotted game time , typically about two hours . </P>
