How long is a flag football game?

Most flag football games are two 20-minute halves played on a running clock, so the game itself takes 40 minutes. With halftime, timeouts and warm-up, plan for about an hour at the field. The exact length depends on the league and the age group.

Here is how long games last at each level, and why a flag football game is so much shorter than a tackle game.

Flag football game length by league

Youth flag football

NFL FLAG, the largest youth program in the US, sets games at two halves of 15 to 25 minutes, with each local league choosing the length. The clock only stops for injuries, halftime and timeouts, and each team gets one 60-second timeout per half.

In practice most youth leagues choose 20-minute halves. Younger age groups often play shorter halves, and tournaments shorten games further so that several can be played in a day.

Because the clock keeps running, a youth game rarely goes much beyond its scheduled slot. Leagues book fields in one-hour blocks for that reason.

High school flag football

High school games are longer. The National Federation of State High School Associations published its first flag football rulebook in 2025, and it sets games at four 12-minute quarters with a halftime of up to 10 minutes.

States can adapt those rules. Washington, for example, plays two 20-minute halves on a running clock, and some middle school programs play 10-minute quarters. If your daughter plays for her school, the state association's rules are the ones that apply.

Adult flag football

Adult leagues usually play two halves of 20 to 25 minutes on a running clock. Many stop the clock in the last one or two minutes of each half, which is where a 40-minute game picks up extra time. Expect to be done within an hour of kickoff.

Flag football at the Olympics

Flag football makes its Olympic debut at the 2028 Games in Los Angeles. It will be played five-on-five on a 50-yard field under international rules. The detailed tournament rules, including timing, are due to be confirmed closer to the Games.

Why flag football games are shorter than tackle football

A high school tackle game has 48 minutes of playing time and takes two hours or more. A flag game with 40 minutes of playing time takes under an hour. The difference is the clock:

• Running clock. In most flag leagues the clock does not stop for incomplete passes or plays out of bounds.
• Fewer timeouts. One per half is common, compared with three in tackle football.
• No kicking game. Most leagues have no kickoffs or field goals, so there are fewer stoppages.
• Short halftime. Often two to five minutes in youth leagues.

How long should you plan to be at the field?

For a standard youth or adult game, plan about 90 minutes in total:

• 20 to 30 minutes before kickoff for arrival and warm-up
• 45 to 60 minutes for the game
• A few minutes after for handshakes and the team talk

Tournament days are different: teams often play three or four shorter games with breaks in between, so plan for most of the day.

Telling everyone the arrival time, not just the kickoff time, is the simplest way to start with a full team. A flag football team app puts that time, the field and who is coming in one place.
