Flag Football Rules

Adult flag football rules — 7v7/5v5 formats, no-run zones, flag pulls, passing rules, and scoring for rec leagues per NIRSA and NFL FLAG standards.

Based on NIRSA / NFL FLAG rules 10 rules Official baseline

Players

7v7 (also 5v5, 4v4)

Game length

2 × 20 min running clock

Field

80 × 40 yds (7v7)

Scoring

TD 6, PAT 1/2, Safety 2

Field & Equipment 1

Flags & Cleats

Sonic-pop or triple-flag belts; no metal cleats

Players wear league-standard flag belts (shirts tucked, flags on hips). Metal cleats are prohibited; shorts must be pocketless.

Players & Teams 1

Co-ed Play Rules

"Gender play" requirements common (e.g., every 3rd down)

Co-ed leagues commonly require a woman to be a primary operative player within every set of downs (e.g., one "closed" play in three), with bonus-point female TDs in some formats.

Game Format 2

Game Format

2 × 20 min running; stop clock final 2 min

Two 20-minute halves with a running clock; the final two minutes of each half use NFHS-style clock stops. Each team gets ~3 timeouts per game.

Overtime

Alternating possessions from the 10 (typ.)

Playoff overtime typically gives each team one possession from the 10-yard line, repeating until decided (2-pt tries forced from round 3).

Gameplay 4

Downs & Lines to Gain

4 downs to reach each 20-yd zone line

Teams have four downs to cross the next zone line (fields are split into 20-yard zones). Failing turns the ball over on downs; most leagues allow a punt declaration on 4th.

Flag Pulls & Guarding

Play dead when flag is pulled; no flag guarding

The ball is dead where the flag is pulled. Runners may not stiff-arm, swat hands, or shield flags — flag guarding is a 10-yard penalty from the spot.

No-Run Zones

5 yds before each zone line & goal line

Within five yards of a first-down line or goal line the offense must pass — no designed runs — preventing power plays at the stripe.

NFL FLAG (5v5)

Passing & Rushing the QB

QB can’t run past LOS (5v5); rush from 7 yds off

In 5v5, the quarterback may not run the ball across the line of scrimmage, and defenders rushing the passer must start seven yards off the line. 7v7 leagues vary — check the rule set.

Scoring 1

Scoring

TD 6; PAT 1 (5 yd) or 2 (10 yd); safety 2

Touchdowns are worth six. After a TD, teams choose a 1-point try from the 5-yard line or 2-point try from the 10. Defensive returns on tries score 2.

Conduct & Safety 1

No Contact

No blocking with contact, no tackling — flags only

Defenders make the "tackle" by pulling a flag. Screen blocking (no hands/arms extended) only; contact fouls yield 10-yard penalties.

Your league may vary

These are the recreational baselines. Leagues on UnderDraft publish their own rule sets — players see exactly which variations apply before every game, and referees enforce them from the sideline.
