How Long Does an American Football Game Last?
Professional and college football games last for 60 minutes, divided into two 30-minute halves and four 15-minute quarters. High school football games last for 48 minutes, divided into two 24-minute halves with four 12-minute quarters. There is one halftime break and shorter breaks after the first and third quarters of the game.
Play stoppages cause football games to last much longer. According to the NFL, the average professional football game stretches over three hours. This is due in part to the NFL's automatic review of each touchdown and turnover as well as an increase in penalties. There has also been an increase in the number of arguments between coaches and referees in addition to inter-player skirmishes after plays.
