A high school football game consists of four 12-minute quarters, totaling 48 minutes of actual playtime. However, the entire game usually lasts between 2 to 3 hours in real time due to clock stoppages for timeouts, injuries, incomplete passes, and other interruptions. Halftime typically lasts about 20 minutes, sometimes longer for special events. The game's length can vary depending on how many stoppages occur, the pace of play, and additional factors like celebrations and ceremonies.
