Flag Football Rules

Ten rules decide almost every flag football game. Some are near-universal across leagues and some your commissioner sets himself, and knowing which is which is the difference between coaching the game and arguing about it. The rules below are written for 5v5, the most common format, with the 7v7 differences noted where they matter.

The short answer

Flag football replaces tackling with pulling a flag, and every rulebook builds on the same core: no blocking of any kind, a defensive rusher who must start a set distance off the ball, no-run zones near each end zone, and a down that ends when a flag comes off rather than when a player is touched. In 5v5, the most common format, that is played on a field roughly 30 by 70 yards with a midfield line to gain, four downs to reach it and four more to score. The rules that decide the most games are the no-run zone, the rush distance and flag guarding, and all three vary enough between leagues that you should read your own rulebook before the first practice.

The ten rules that decide games

Near-universal unless noted. Where a rule commonly varies, the card says so, because a page that presents one league’s rulebook as the sport’s is how coaches end up arguing on a Saturday.

Universal

Five a side, everyone eligible

A quarterback and four receivers, with every player eligible to catch. There are no ineligible linemen in 5v5, which is why formations matter more here than in tackle: any of the four can be your primary.

Universal

No blocking, at all

Not on offense, not on defense, not on a screen. A receiver may stand still and let a defender run into him, but moving into a defender to obstruct him is illegal contact. This single rule is why traffic concepts like bunch and mesh work.

Varies by league

The no-run zone

A five-yard zone before each end zone and usually before the midfield line to gain, where the offense must pass. It exists to stop teams simply running a quarterback sneak from the two. Zone size and whether it applies at midfield both vary.

Varies by league

The rush line

Defenders may not rush the quarterback until they start from a set distance off the ball, most commonly seven yards, and a rusher is often declared before the snap. Some leagues require a count instead. Check yours: it changes how much time your quarterback has on every single play.

Universal, most-called

Flag guarding

Using a hand, arm or the ball to keep a defender off your flag. Illegal everywhere and the most frequently called penalty in youth flag. Teach ball-carriers to keep both hands on the ball and turn their hips instead.

Near-universal

The line to gain

Four downs to reach midfield, then four more to score. There are no chains and no measurement crew: midfield is the marker. It makes fourth down far more common than in tackle football, which is why a short-yardage package earns its place.

Universal

A down ends when a flag comes off

Not when the ball-carrier is touched. If a flag falls off on its own, most rulebooks rule the player down at the spot with a one-hand touch. Play to the flag, not the whistle you are used to.

Varies by league

The quarterback cannot run

In most rulebooks the quarterback may not advance the ball himself unless it has first been handed off or pitched and returned. Some adult leagues allow a scramble after a set count. This is the rule most often misunderstood by coaches new to flag.

Varies by league

Laterals and handoffs

Handoffs behind the line are legal almost everywhere. Forward passes past the line and multiple laterals are usually not. Some leagues allow one backward pass per down, so trick plays are worth checking before you install one.

Near-universal

Scoring

Six for a touchdown, then a choice of extra point: usually one point from five yards or two points from ten. Safeties are two. Interception returns for a touchdown score the same six, which is worth telling a young defense out loud.

What your league sets, and why it matters

Four of the ten rules above vary: the no-run zone, the rush distance, whether the quarterback may scramble, and what counts as a legal lateral. Every one of those changes how you call plays, not just how you referee them.

A seven-yard rush and a five-second count are completely different games for a quarterback. A no-run zone at midfield turns fourth and one into a passing down. If you install a playbook without reading these, you will discover them during a game.

Common questions

How many players are on the field in 5v5 flag football?

Five per side, hence the name. Typically a quarterback and four eligible receivers on offense, with all five defenders eligible to rush or cover. Nobody is an ineligible lineman in 5v5, which is the biggest structural difference from tackle football.

Can you run the ball in 5v5 flag football?

Usually yes, except inside the no-run zones. Most 5v5 rulebooks mark a five-yard zone before each end zone and before the midfield line-to-gain where the offense must pass. The quarterback also cannot normally run with the ball unless it has first been handed off or pitched.

What is flag guarding?

Using a hand, arm or the ball to block a defender from reaching your flag. It is illegal in essentially every flag football rulebook and it is the most commonly called penalty in youth games, usually costing the offense five to ten yards from the spot.

How long is a 5v5 flag football game?

Most youth leagues play two halves of 20 to 25 minutes with a running clock, stopping only for timeouts, injuries and the final minute. Your league sets this, so check the local rulebook rather than assuming.

Is blocking allowed in flag football?

No. There is no blocking of any kind in standard flag football, on offense or on defense. Receivers may screen by standing still, but moving into a defender to obstruct him is illegal contact.
