A college football game is officially 60 minutes long, divided into four 15-minute quarters, which is the same as an NFL game. However, due to clock stoppages, timeouts, halftime, and other events, the actual duration of a college football game typically lasts about 3 hours and 20 to 3 hours and 30 minutes on average. This can vary depending on factors such as overtime, weather delays, or the pace of the game. Halftime in college football is usually 20 minutes, which is longer than the NFL halftime period. Recent rule changes have slightly shortened the game duration by adjusting when the game clock stops, especially around first downs and out-of-bounds plays.
