Flag Football Rules Explained: 5v5, 7v7 and Olympic Format

Flag football is American football without tackling. A defender stops the ball carrier by pulling a flag from the runner’s belt. In common non-contact rulebooks, players also cannot block, screen or tackle, so the game is built around space, quick passing, legal handoffs and clean flag pulls.

The rules below match the common NFL FLAG and USA Football style, but local leagues can change details. Before a tournament or school season, check the organizer’s sheet for player count, field size, quarterback running, rush distance, no-run zones and scoring.

How a flag football game starts

Most youth and rec games begin with a possession, not a traditional tackle-football kickoff. The offense starts at a set spot and has a limited number of downs to advance. In many 5v5 formats, the offense gets four plays to cross midfield. If it succeeds, it gets four more plays to score.

That structure keeps the game moving and removes high-contact kickoff returns. It also explains why midfield matters so much. The line-to-gain is not just a random stripe. It decides whether the offense keeps the ball.

Pulling the flag ends the play

A legal flag pull is the basic defensive tackle in flag football. The defender reaches for one of the flags on the ball carrier’s belt and removes it cleanly. Once the flag is pulled, the play ends at that spot.

A defender should not grab clothing, hold the runner, shove, trip or make body contact to force a stop. If a flag falls off by itself, if the runner steps out of bounds, or if the ball carrier goes down, the rulebook will define where the play is dead. The NFL Play Football glossary is useful here because it lists common dead-ball situations in plain language.

Blocking and screening are not allowed in non-contact flag

USA Football describes flag football as a non-contact game with no linemen or blocking. That changes nearly everything. The center snaps the ball and becomes a receiver. Receivers run routes, not picks. Teammates near the ball carrier must avoid obstructing defenders.

This is the rule beginners break without meaning to. In tackle football, helping the runner by getting in a defender’s way is normal. In flag football, that can become illegal screening or blocking. Teach players to clear space after the catch, not escort the runner like a blocker.

Can the quarterback run?

In common NFL FLAG-style 5v5 rules, the player who receives the snap cannot simply run across the line of scrimmage. The quarterback can pass, hand off or pitch the ball backward. After a legal handoff or backward pass, another player may run when the play is not inside a no-run zone.

This rule balances the game. Without tackling or normal pass rush, a fast quarterback would be too hard to stop if every play could become a keeper. Some 7v7, adult or local leagues allow more quarterback movement, which is why the rule sheet matters before you design the offense.

The 7-second passing rule

In NFL FLAG’s public rules, the quarterback has seven seconds from receiving the snap to release the ball. If the quarterback still has the ball after the count, the play is dead. NFL FLAG also notes that once a backward handoff, pass or lateral happens, the seven-second rule no longer applies in that same way.

For coaches, this rule is the playbook filter. Long-developing routes are risky unless the defense gives the quarterback time. Quick outs, hitches, slants, mesh routes, screens and center releases usually fit youth flag better than slow double moves.

The 7-yard rush rule

Many youth flag formats use a seven-yard rush line. A legal rusher starts from that distance behind the line of scrimmage and, in NFL FLAG’s public rules, identifies by raising a hand until the snap. Once the ball is handed off or pitched backward, other defenders may be able to cross the line depending on the rulebook.

The rusher still cannot crash into the passer. Good rushing is controlled speed: close the space, break down, get hands ready and pull the flag if the quarterback becomes a legal runner.

No-run zones

No-run zones are areas where the offense must use a pass play. NFL FLAG’s public glossary describes no-run zones before each goal line and at midfield. USA Football’s current public rules language emphasizes the five-yard area before each end zone. Because those details can differ, field setup and play calling should follow the specific rulebook.

No-run zones exist to reduce contact in tight spaces. Near the goal line, a simple power run would tempt players to lower shoulders, block or crowd the ball carrier. A required pass play spreads the field and keeps the game closer to its non-contact purpose.

Flag guarding and other common penalties

Flag guarding is one of the easiest calls to understand and one of the hardest habits for new runners to break. The ball carrier cannot protect the flag with a hand, arm, ball or body move that blocks the defender’s reach.

Common penalties include:

• flag guarding
• illegal contact
• illegal blocking or screening
• illegal rush
• offside or false start
• delay of game or holding the ball past the pass clock
• unsportsmanlike conduct

The exact yardage depends on the league. Teach the concept first: make people miss with space and cuts, not by shielding the flag.

5v5, 7v7 and Olympic flag football

5v5 is the best-known modern format because NFL FLAG centers much of its youth game there and the Olympic debut at LA28 is planned as 5v5. The NFL’s LA28 announcement says the Olympic competition will use five players on the field and 10-player rosters.

7v7 is also common, especially when organizers want more players involved or want a format closer to a full passing game. USA Football separates 5v5 and 7v7 rulebook options, and NFHS has its own high-school flag football rules track. Those formats can look similar on TV or from the sideline, but the rulebook details may not match.

What equipment do players need?

A basic flag football player needs a football, a flag belt, flags, athletic clothes and shoes suitable for the surface. Most non-contact leagues do not require pads. Some school or adult leagues restrict pockets, jewelry, metal cleats or certain headgear because those items can interfere with flag pulls or safety.

For a team, add cones, a field diagram, spare flags, a pump, first-aid supplies and a printed rule sheet. If you are setting up the field yourself, confirm the layout before practice with our flag football field dimensions guide.
