Flag football looks simple from the sideline. You snap the ball, throw it, and pull a flag instead of tackling. Then you actually start coaching a team or stepping onto the field, and you realize the flag football rules change depending on whether you are playing NFL Flag, i9 Sports, USA Football 7v7, a recreational adult league, or the Olympic format coming to Los Angeles in 2028.
This guide pulls every version of the flag football rules into one place. You get the universal rules first, then the specific variations for 5v5, 7v7, NFL Flag, i9, youth, and Olympic play. By the end you will know the field dimensions, the pass clock, the no-run zones, what counts as a dead ball, what gets you a 5-yard penalty versus a 10-yard penalty, and the exact differences between formats so you can switch leagues without getting confused on game day.
If your team also needs flag football uniforms before the season starts, we cover that at the end of the guide.
The Core Flag Football Rules
If you only have 30 seconds, here is what every flag football player needs to know:
- No tackling, no blocking with extended arms, no diving at the flag.
- The play ends when a defender pulls one flag from the ball carrier’s belt.
- The quarterback has 7 seconds to throw the ball in most formats.
- Teams get 4 downs to reach midfield, then 4 more downs to score.
- Touchdowns are worth 6 points. Extra points are 1 from the 5-yard line or 2 from the 10-yard line.
- Flag guarding (using your hand or arm to block a flag pull) is a penalty.
- Most leagues have “no-run zones” within 5 yards of midfield and 5 yards of the end zone.
The rest of this article explains how those rules change across formats and fills in every specific detail you will actually need to coach, play, or officiate a game.
What is Flag Football?
Flag football is a non-contact version of American football. Instead of tackling the ball carrier, defenders end the play by removing one of two flags attached to a belt around the runner’s waist. The flags hang on each hip in most formats. Some recreational leagues use a third flag in the back.
The sport grew from a backyard variation into an organized national activity, and in October 2023 the International Olympic Committee added flag football to the 2028 Los Angeles Summer Olympics program. That decision pulled millions of new players into the sport and pushed flag football rules toward more global standardization.
The Universal Rules That Apply Everywhere
Before you pick a format, learn these. Every flag football league enforces these flag football rules with only minor wording differences.
No Contact
Tackling, blocking with extended arms, screening with the body, diving at a flag, and stiff-arming a defender are all penalties. Incidental contact during a flag pull is allowed because reaching for the belt sometimes brushes the runner. Deliberate contact is not.
Flag Guarding
The ball carrier cannot use a hand, arm, elbow, or the ball itself to keep a defender from pulling a flag. This includes lowering the shoulder, swinging an elbow, or covering the flag with the football. Penalty is usually 5 to 10 yards from the spot of the foul.
Forward Passes Only
Each play allows one forward pass, and it must be thrown from behind the line of scrimmage. Backward passes, laterals, and pitches behind the line are unlimited. Once the ball crosses the line, no more forward passes are legal.
Fumbles
Most flag football leagues treat any ball that hits the ground as a dead ball at the spot of the drop. There are no live fumbles. This rule speeds up the game and reduces pile-ups.
Substitutions
Teams can substitute freely between plays. Players cannot enter the field while the ball is live.
Flag Football Field Dimensions
Field size depends on the format and the age group, but these are the standards:
| Format | Length | Width | End Zones |
| NFL Flag (5v5) | 70 yards | 30 yards | 10 yards each |
| USA Football 7v7 | 80 yards | 40 yards | 10 yards each |
| Adult Recreational 8v8 | 80 yards | 40 yards | 10 yards each |
| Olympic / IFAF (5v5) | 50 meters (about 55 yards) | 25 meters (about 27 yards) | 8 meters each |
| Pre-K and Kindergarten | 50 yards | 20 yards | 7 to 10 yards |
The field is divided in half by a midfield line that doubles as the line to gain for a first down. Each half of the field has a no-run zone within 5 yards of midfield and within 5 yards of the end zone.
Equipment Rules
Players need a flag belt with two flags, a mouthguard in most youth leagues, and athletic shoes. Metal cleats are banned across every major league. Soft rubber or molded cleats are allowed.
The flags themselves must be a contrasting color to the team’s shorts or pants.
If your flags are blue, you cannot wear blue bottoms. Most rulebooks require flags to be at least 2 inches wide and 14 inches long. The belt has to use a quick-release clip so it pops free if a defender grabs the belt instead of the flag.
Jewelry, hats with brims, and hard casts are not allowed. Soft-shell helmets and protective eyewear are permitted in most formats, and some 7v7 adult leagues require them.
How a Flag Football Game Starts
There is no kickoff. Every game starts with a coin toss. The visiting team calls heads or tails. The winner of the toss chooses to start on offense or defense, and the loser picks which end of the field to defend. The team that starts on offense begins from their own 5-yard line in NFL Flag rules. Other formats start from the 10-yard line or even at midfield.
After a touchdown, the team that just scored kicks off in tackle football. In flag football, the team that was scored on simply takes possession from their own 5-yard line and starts the next drive. This keeps the game moving and removes the special teams element entirely.
Downs and Distance
The down system in flag football is simpler than tackle. The offense gets 4 plays to cross midfield. If they cross midfield, they get 4 more plays to score. If they fail to cross midfield in the first 4 downs, the other team takes over at the spot of the ball.
Some recreational leagues allow punts on 4th down. Most NFL Flag and youth leagues do not. The team simply turns the ball over on downs at the spot of the last play.
The 7-Second Pass Clock
This is the rule that separates flag football rules from every other version of the sport. The quarterback has 7 seconds from the snap to release a forward pass. The referee starts a count out loud or watches a clock on the field.
If the quarterback does not throw within 7 seconds, the play is dead, the down counts, and the ball goes back to the line of scrimmage. The pass clock stops once the ball is handed off, pitched, or laterally behind the line. After that, the play continues until a flag is pulled or another dead ball trigger happens.
The clock is what forces fast decisions and keeps the offense from holding the ball for hidden runs. It also means quarterbacks who hold the ball too long get punished even without a sack.
No-Run Zones
The no-run zone is a 5-yard area before midfield and a 5-yard area before each end zone. When the line of scrimmage is inside one of these zones, the offense cannot run the ball. Every play has to be a forward pass.
The zones exist to prevent power-running and quarterback sneaks near the goal line. Without them, a strong team could just push the ball forward one yard at a time using the quarterback.
The no-run rule makes the offense throw and gives the defense a real chance to make a stop.
If a run play happens inside a no-run zone, the play is dead, the down is consumed, and most leagues add a 5-yard penalty.
Rushing the Quarterback
The defense is allowed to send one rusher to pressure the quarterback, but with conditions. The rusher has to start at least 7 yards behind the line of scrimmage. The referee marks this rush line with a cone or a verbal cue.
In some leagues the rusher has to raise a hand to identify themselves before the snap. Crossing the rush line before the ball is snapped is a penalty for offsides. Sending more than one rusher is illegal under most flag football rules unless the offense crosses the line of scrimmage with a run, at which point the rest of the defense can pursue.
Once the quarterback hands the ball off, the rush rules end and any defender can chase the ball carrier.
What Ends a Play (Dead Ball)
A play is dead when any of these happen:
- A flag is pulled from the ball carrier
- A flag falls off on its own (the runner is down at that spot)
- The ball carrier steps out of bounds
- The ball carrier’s knee, elbow, or any body part except the hand or foot touches the ground
- A pass is incomplete
- The ball hits the ground after a snap, fumble, or drop
- A touchdown, safety, or extra point is scored
- The 7-second pass clock expires
- The game clock expires
If a flag falls off before the runner has the ball, that player is ruled down by a one-hand touch the moment they catch the ball.
Scoring in Flag Football
| Score | Points |
| Touchdown | 6 |
| Extra point from 5-yard line (pass only) | 1 |
| Extra point from 10-yard line (run or pass) | 2 |
| Defensive return on extra point | 2 |
| Safety | 2 |
| Defensive touchdown (interception or fumble return) | 6 |
A safety happens when the ball carrier is downed in their own end zone. After a safety, the team that gave it up has to give the ball back to the other team at midfield.
Common Penalties and Yardage
| Penalty | Yards | Notes |
| Offsides | 5 | Replay the down |
| False start | 5 | Replay the down |
| Illegal motion | 5 | Replay the down |
| Holding | 5 | From the spot of the foul |
| Flag guarding | 5 to 10 | From the spot of the foul |
| Illegal contact | 5 to 10 | Defensive automatic first down |
| Pass interference | Spot foul | Offense gets the ball at the foul spot |
| Illegal flag pull (before catch) | 5 | Automatic first down |
| Roughing the passer | 5 to 10 | Replay or first down |
| Unsportsmanlike conduct | 10 to 15 | Possible ejection |
| Illegal rush (rusher across line early) | 5 | Replay the down |
Penalties are usually assessed from the line of scrimmage unless they are spot fouls. Defensive penalties on the last play of a half cannot end the game unless the offense declines.
5v5 Flag Football Rules
The 5v5 format is the most common version played in the United States. Every player on offense is an eligible receiver. The center snaps the ball and immediately becomes a route runner.
Standard 5v5 rules:
- 5 players on the field per team
- Field is 70 yards long and 30 yards wide with two 10-yard end zones
- 4 downs to reach midfield, 4 downs to score
- 7-second pass clock
- One designated rusher from at least 7 yards behind the line
- No-run zones in effect
- Two halves of 20 minutes each with a running clock
- Each team gets two timeouts per half
- Overtime starts at the 5-yard line, each team gets one possession to score
5v5 is the format the IOC chose for the 2028 Olympics. It is fast, it spreads the field, and it favors quarterbacks who can read coverage and receivers who can separate.
7v7 Flag Football Rules
7v7 is the format used by competitive adult leagues and high school showcases. The extra players allow more complex offensive formations and stronger defensive coverage.
Key 7v7 rules:
- 7 players on the field per team
- Field is 80 yards long and 40 yards wide with two 10-yard end zones
- 4 downs to reach midfield, 4 downs to score
- 7-second pass clock
- One blitzer permitted from 7 yards behind the line
- Some 7v7 adult leagues allow open-arm blocking above the waist
- Two halves of 20 to 25 minutes each
- College and adult 7v7 events sometimes require soft-shell helmets
The 7v7 game looks closer to traditional football. Defenses can run zone coverage, blitz packages, and disguise looks because they have more bodies. The format is the proving ground for athletes who want to play 5v5 at the international level.
NFL Flag Football Rules
NFL Flag is the largest organized youth flag football program in the world, with over 700,000 boys and girls playing in leagues across the country. Their rulebook is the standard most other youth leagues borrow from.
Specific NFL Flag rules:
- 5 on 5 format with 5 to 10 players per team total
- Field is 30 yards wide and 70 yards long with two 10-yard end zones
- Two halves of 20 minutes with a continuous clock
- Clock stops only in the last 2 minutes of the second half
- Each team gets one 60-second timeout per half
- 7-second pass clock with no intentional grounding
- One rusher per play from a 7-yard rush line
- No fumbles. The ball is dead when it hits the ground
- No-run zones 5 yards before midfield and 5 yards before each end zone
- Touchdowns 6 points, 1-point conversion from the 5, 2-point conversion from the 10
- Interceptions on 1-point conversions can be returned for 2 points
- Mercy rule: if a team is up by 25 points in the second half, the game ends
The NFL Flag rulebook also covers grade-based modifications for ages 5 to 6, 7 to 8, 9 to 10, 11 to 12, and 13 to 14, with smaller fields and shorter halves for younger divisions.
i9 Sports Flag Football Rules
i9 Sports runs one of the largest youth flag football programs outside of NFL Flag, with a heavy focus on player development for ages 3 to 14. The i9 ruleset prioritizes participation and learning over competition.
Core i9 flag football rules:
- 5 on 5 format for most age groups, 4 on 4 for ages 3 to 5
- Field size scales by age. The smallest fields are 30 yards by 15 yards
- 4 downs to score on a shorter field with no midfield first down
- No score is announced for ages 3 to 5
- 7-second pass clock for ages 7 and up
- No rushing the quarterback in the youngest divisions
- Coaches are allowed on the field during plays in the 3 to 5 age group
- Every player must play at least half the game (mandatory participation rule)
- No pulling flags from a player without the ball
The i9 system is built so that a 4-year-old who has never touched a football can show up and play in the first practice. The rules get stricter and more competitive as players move up through the age divisions.
Youth Flag Football Rules
Youth flag football covers any league for players under age 14, and the rules adjust for safety and skill level. Most youth leagues, including NFL Flag and i9, share these features:
- Smaller fields than adult leagues
- Shorter halves, usually 18 to 24 minutes total game time
- Mandatory mouthguards
- No defensive linemen or pre-snap rushers in the youngest divisions
- Mandatory minimum playing time per child
- Coaches allowed on the field for play-calling in the youngest age groups
- Strict no-contact enforcement, with quick whistles for incidental shoves
- Modified scoring in some leagues to reward effort and not just touchdowns
If you are coaching a youth team, the most important rule to teach first is flag guarding. Kids instinctively cover their flags with their hands when chased. Breaking that habit early saves a lot of penalties later.
Olympic Flag Football Rules
The 2028 Los Angeles Olympics will use the IFAF (International Federation of American Football) flag football rulebook for the gold medal tournament. The format is 5 on 5 and the rules are designed to look clean on television and travel across countries that do not have a deep American football culture.
Olympic flag football specifics:
- 5 on 5 format
- Field is 50 meters long by 25 meters wide with 8-meter end zones
- Two halves of 20 minutes with a stopped clock in the last 2 minutes
- 7-second pass clock
- 4 downs to reach midfield, 4 downs to score
- One rusher from 7 yards behind the line
- No fumbles, no kickoffs, no punts
- Touchdowns 6 points, 1-point conversion from 5 yards out, 2-point conversion from 10 yards out
- Tiebreaker is a sudden-death overtime starting at the 5-yard line
USA Football is the national governing body that selects the United States Olympic flag football teams. Tryouts and qualification events run through 2027, and the final rosters lock in early 2028.
Flag Football Rules for Beginners
If you are completely new to the sport, this is your starter checklist. Memorize these and you will not get lost on your first day.
- Two flags hang on your belt, one on each hip. When a defender pulls one, you are down at that spot.
- Do not cover your flags with your hands or the ball. That is flag guarding and it is a penalty.
- The quarterback has 7 seconds to throw. After 7 seconds the play is dead.
- You get 4 plays to cross midfield. If you cross it, you get 4 more plays to score the touchdown.
- There are no kickoffs and usually no punts. The ball just changes possession after a turnover or score.
- Touchdown is 6 points. Extra point is 1 from the 5-yard line or 2 from the 10-yard line.
- The ball carrier cannot leave their feet to dive forward, but they can leap to catch a pass.
- There is no contact. No tackling, no blocking with arms, no diving at a flag.
- Inside 5 yards of midfield or the end zone, you have to throw. No running plays in the no-run zone.
- Every player on offense can catch a pass, including the center after they snap the ball.
That is the entire game in 10 lines. The advanced rules above just refine these basics for specific formats.
Frequently Asked Questions
Is flag football a contact sport?
No. Flag football is officially a non-contact sport. Incidental contact during flag pulls and route running is allowed, but tackling, blocking, and intentional contact are penalties.
How long is a flag football game?
Most adult and competitive games run 40 to 50 minutes total in two halves. Youth games run 20 to 40 minutes total depending on age group.
Can the quarterback run in flag football?
Flag football rules vary by format. In most NFL Flag and youth formats, the quarterback cannot cross the line of scrimmage as a runner. In adult 7v7 leagues, the quarterback can run after a defender crosses the line of scrimmage on a rush. Always check your specific league rule.
What is the 7-second rule in flag football?
The quarterback has 7 seconds from the snap to release a forward pass. If they hold the ball longer, the play is dead and the down counts. The clock resets if the ball is handed off behind the line.
Are there fumbles in flag football?
Almost no league counts live fumbles. The ball is dead the moment it hits the ground, and possession stays with the team that had the ball when it was dropped, unless the ball was lost going forward.
How many players are on a flag football team?
The game is played 5 on 5 in NFL Flag, i9, and Olympic formats. The 7v7 format uses 7 players, and some adult recreational leagues play 8v8.
Is blocking allowed in flag football?
Flag football rules prohibit blocking in most formats. Some adult 7v7 leagues allow open-arm blocking above the waist with no contact to the head or below the hips. Youth leagues never allow blocking.
What happens if my flag falls off?
You are considered down at the spot the flag fell off. If you catch the ball without a flag on your belt, you are down immediately when you touch the ball with one hand from a defender.
Can you play flag football in the rain?
Yes. Most leagues play through light rain. Games are usually called only for lightning, severe weather, or unsafe field conditions.
What size football is used in flag football?
NFL Flag uses a junior-size football for ages 9 to 11, an intermediate or youth size for ages 12 to 14, and an official size for adult and high school leagues. i9 Sports uses a peewee size for the youngest divisions.
Final Thoughts
Flag football rules look complicated when you read every variation back to back, but the format you actually play decides which rules matter for you. If you are coaching NFL Flag, the NFL Flag rulebook is the only one that counts.
If you are running an adult 7v7 squad, learn the IFAF rules so you are ready when the Olympic talent pipeline opens up. And if you want to take it further and organize your own league from scratch, our guide on how to start a flag football league walks through field permits, registration, scheduling, and budgeting.
The sport is in the middle of the biggest growth period in its history. The rules will keep tightening into one global standard over the next few years as the 2028 Olympics get closer. The 7-second pass clock, the no-run zone, the 5-on-5 format, and the no-contact rule are all here to stay.
