NFHS Flag Football Rules Explained: Format, Field, Penalties & More
Everything you need to know about the NFHS flag football ruleset, including 7-on-7 format, field dimensions, clock rules, and common penalties.
Understanding the NFHS Flag Football Ruleset
The National Federation of State High School Associations (NFHS) published its official flag football rules to create a standardized framework for the rapidly growing sport. These rules govern most sanctioned high school programs in the United States and are designed to prioritize safety, fast-paced play, and accessibility.
Game Format
NFHS flag football is played 7 versus 7 on a rectangular field. Games consist of two halves, each 20 minutes of running clock, with the clock stopping in the final two minutes of each half for incomplete passes, out-of-bounds plays, scores, and timeouts. Each team receives three timeouts per half.
Field Dimensions
The standard NFHS field is 80 yards long and 40 yards wide, with two 10-yard end zones. The field is divided into four 20-yard zones, and teams must gain a first down by crossing into the next zone. There is no traditional 10-yard chain—crossing the zone line resets the downs.
Downs and Possession
The offense has four downs to advance the ball past the next zone line. If the offense fails, possession changes at the spot of the ball. There are no punts in the NFHS format; teams that turn the ball over on downs simply give it to the opponent at that spot.
Flag Mechanics
Each player wears a belt with flags on each hip. A legal flag pull ends the play—the ball is spotted where the runner's feet were when the flag was removed. Defenders may not hold, push, or dive at the ball carrier. Flag guarding by the ball carrier is a penalty.
Common Penalties
- Flag guarding – 5 yards from the spot of the foul, loss of down
- Illegal contact / holding – 10 yards from the line of scrimmage
- Pass interference (offensive or defensive) – 10 yards from the line of scrimmage
- Delay of game – 5 yards
- Illegal forward pass – 5 yards from the spot and loss of down
- Offside – 5 yards
No-Run Zones
Under NFHS rules, no-run zones are marked 5 yards before each zone line and the goal line. When the ball is spotted inside a no-run zone, the offense must execute a pass play—running plays are not permitted. This rule prevents short-yardage power plays and keeps the game pass-oriented.
