Flag Football Rules: The Complete Guide
Everything coaches, parents, and players need to know about flag football. From basic rules and field dimensions to positions, plays, and penalties.
Flag football is one of the fastest-growing sports in America. It's the entry point for millions of kids, a sanctioned high school sport in more than 20 states, and it'll make its Olympic debut at the 2028 LA Games. Whether you're coaching your first season, organizing a rec league, or just trying to understand what your kid is playing, this guide covers everything you need to know about flag football rules.
We'll walk through the basics of how the game works, break down flag football field dimensions for different formats, explain every flag football position, and cover popular plays for both 5-on-5 and 7-on-7. We'll also compare NFL FLAG rules to typical rec league rules so you know exactly what applies to your situation.

How to Play Flag Football
The basics of the game, explained simply.
Flag football follows the same basic idea as tackle football. Two teams compete to move the ball down the field and into the opposing team's end zone. The difference? No tackling. Instead of bringing the ball carrier to the ground, defenders pull one of the flags attached to their belt. Once a flag is pulled, the play is dead.
Each team gets a set number of downs (usually four) to cross midfield or score. If the offense doesn't advance past midfield in those downs, the other team takes over. If they do cross midfield, they get a new set of downs to score.
Games are typically played in two halves with a running clock. Most youth and rec games run 20 to 25 minutes per half. There's no kickoff in most flag football formats. Instead, the game starts with the ball at the offensive team's 5-yard line.
Key Differences from Tackle Football
- No contact: No tackling, no blocking below the waist, no stiff-arming
- Flag pulling: The play ends when a defender pulls a flag, not when the ball carrier is down
- Smaller teams: 5-on-5 or 7-on-7 instead of 11-on-11
- Shorter fields: 25 to 40 yards wide, 50 to 80 yards long
- No kickoffs or punts: Possessions start from a set yard line
- Running clock: Faster-paced games with fewer stoppages
Flag Football Field Dimensions
Standard field sizes for every format.
Flag football fields are smaller than a standard tackle football field (which is 53 1/3 yards wide by 100 yards long). The exact dimensions depend on the format and age group you're playing in.
| Format | Width | Length | End Zones |
|---|---|---|---|
| 5-on-5 (NFL FLAG) | 25 yards | 70 yards total | 10 yards each |
| 7-on-7 (Standard) | 30 to 40 yards | 80 yards total | 10 yards each |
| Youth (Ages 5 to 7) | 20 yards | 50 yards total | 7 yards each |
| Youth (Ages 8 to 10) | 25 yards | 60 yards total | 10 yards each |
| High School | 30 to 40 yards | 80 yards total | 10 yards each |
Most fields also include no-run zones, typically marked 5 yards before each end zone and sometimes at midfield. Inside these zones, the offense must throw a pass. No handoffs or direct runs are allowed.
How Scoring Works
Touchdowns, extra points, safeties, and more.
Scoring in flag football is similar to tackle football but with some tweaks that reward risk-taking and keep games close.
Touchdown
Carry or catch the ball in the opponent's end zone. Same as tackle football.
Extra Point
After a TD, teams choose: 1 point from the 5-yard line, or 2 points from the 10-yard line. No kicking.
Safety
If a ball carrier's flag is pulled in their own end zone, the defense scores 2 points and gets the ball.
Defensive TD
If a defender intercepts a pass and returns it to the end zone, they score a touchdown.
Some leagues award bonus points for longer extra-point attempts (2 points from the 12-yard line, for example). Others keep it simple with just the 1-point and 2-point options. Check your league's scoring rules before the season starts.
Flag Football Positions
Every position on offense and defense, broken down by format.
Offensive Positions
Quarterback (QB)
The leader of the offense. Receives the snap from center, reads the defense, and either passes the ball or runs it (when rules allow). In flag football, the QB has a huge role because most plays are pass-based. A strong-armed, quick-thinking QB can dominate a game.
Center
Snaps the ball to the QB. After the snap, the center can run a route as an eligible receiver. In 5-on-5, this is a critical position because you need every player on the field running routes.
Wide Receivers (WR)
The primary pass catchers. In 5-on-5, you'll typically have two to three receivers on the field. In 7-on-7, you can spread out with four or five. Speed and route-running ability matter more than size in flag football.
Running Back (RB)
Used mainly in 7-on-7 formats. Lines up behind the QB and can take handoffs, run routes out of the backfield, or serve as a safety valve on broken plays. Not every flag football offense uses a dedicated RB.
Defensive Positions
Rusher
The player who rushes the QB after the snap. In most leagues, only one player can rush, and they must line up at least 7 yards from the line of scrimmage. The rusher's job is to pressure the QB into a bad throw or pull the flag before they can pass.
Cornerbacks (CB)
Cover the outside receivers. Cornerbacks play man-to-man coverage and are responsible for pulling the flag if their receiver catches the ball. Quick feet and the ability to read routes are essential at this position.
Safety
Lines up deeper than the cornerbacks and provides help over the top. In zone defenses, the safety reads the QB's eyes and covers whichever receiver enters their zone. In 5-on-5, the safety often doubles as a second cornerback.
Common Formations and Plays
Basic offensive setups for 5-on-5 and 7-on-7 flag football.
5-on-5 Flag Football Plays
With only five players on the field, every player runs a route (except the QB). Here are three formations that work at every level.
Trips Right / Trips Left
Three receivers line up on one side of the center, creating a numbers advantage. The outside receiver runs a deep route, the middle receiver runs a crossing route, and the slot receiver runs a quick out. The center sneaks out to the weak side as a safety valve.
Stack Formation
Two receivers line up directly behind each other on one side. At the snap, they split in different directions, creating a natural pick. The front receiver runs a quick slant while the back receiver runs a deep corner route. Hard to defend in man coverage.
Spread
Two receivers on each side of the center, spaced wide. This stretches the defense horizontally and opens up the middle of the field. Great for teams with a QB who can throw accurately to either side.
7-on-7 Flag Football Plays
Seven-on-seven gives you more options and lets you build more complex play designs. Here are three staple formations.
Doubles
Two receivers on each side with an RB in the backfield. This balanced look keeps the defense honest and opens up both the run and pass game. The RB can take a handoff, swing out to the flat, or stay in to block the rusher.
Empty Set
All five receivers spread out with no RB behind the QB. This gives the QB five route options and makes it very difficult for the defense to cover everyone. The tradeoff: no one to block the rusher, so the QB needs to get the ball out fast.
Bunch Right / Bunch Left
Three receivers cluster together on one side. At the snap, they run crossing routes in different directions, creating confusion for defenders. Works especially well in the no-run zone when you need a short passing play near the goal line.
NFL FLAG vs Rec League Rules
The key differences between organized and casual flag football.
NFL FLAG is the largest flag football program in the country, with over 1,600 leagues across all 50 states. Their rules are standardized and widely used as the baseline for youth flag football. But plenty of rec leagues, church leagues, and intramural programs run their own variations.
| Rule | NFL FLAG | Typical Rec League |
|---|---|---|
| Format | 5-on-5 only | 5-on-5 or 7-on-7 |
| Field Size | 25 x 70 yards | Varies (often 30 x 80) |
| No-Run Zones | 5 yards from each end zone + midfield | Varies or none |
| QB Running | Only if a defender rushes | Rules vary widely |
| Rushing | 1 rusher, 7-yard buffer | 1 to 2 rushers, buffer varies |
| Flags | 3-flag belt required | 2 or 3-flag belts |
| Game Length | Two 20-minute halves | Two 15 to 25 minute halves |
The best advice for coaches and parents: get a copy of your league's specific rulebook before the season starts. Even if your league follows NFL FLAG rules, there might be local modifications for age groups, field availability, or safety.
Common Flag Football Penalties
Know the rules so your team doesn't lose yards.
Flag football has fewer penalties than tackle football, but the ones that exist can swing a game. Here are the most common calls you'll see.
Flag Guarding (10 yards)
Using your arm, hand, or the ball to prevent a defender from pulling your flag. This includes swatting at a defender's hand or lowering your shoulder. It's the most common penalty in youth flag football.
Offsides (5 yards)
Lining up past the line of scrimmage before the snap. For rushers, this means starting inside the 7-yard buffer zone.
Pass Interference (10 yards + automatic first down)
Making contact with a receiver before the ball arrives. This includes grabbing, pushing, or bumping a receiver while they're running a route.
Illegal Contact (10 yards)
Any contact beyond what's allowed. Blocking, pushing off, tripping, or holding another player. Remember: flag football is a non-contact sport.
Delay of Game (5 yards)
Not snapping the ball before the play clock expires. Most leagues give the offense 25 to 30 seconds to snap the ball after the referee marks it ready for play.
Illegal Forward Pass (5 yards + loss of down)
Throwing a forward pass from beyond the line of scrimmage, or throwing a second forward pass on the same play. Only one forward pass per play is allowed.

Frequently Asked Questions
What are the basic rules of flag football?
Flag football is a non-contact sport where defenders pull a flag from the ball carrier's belt instead of tackling. Teams advance the ball by passing and running, and score by crossing the opponent's goal line. Most games use 5-on-5 or 7-on-7 formats, with shorter fields and shorter game times than tackle football. There's no blocking below the waist, no diving for flags, and the play ends the moment a flag is pulled.
How big is a flag football field?
Flag football field dimensions depend on the format. A standard 5-on-5 field is 25 yards wide by 70 yards long (including two 10-yard end zones). A 7-on-7 field is typically 30 to 40 yards wide by 80 yards long (including end zones). Youth fields are often scaled down further based on age group, sometimes as small as 20 yards wide by 50 yards long.
How many players are on a flag football team?
Most flag football leagues play 5-on-5 or 7-on-7. NFL FLAG, the largest youth program in the country, uses a 5-on-5 format. Many recreational and high school leagues play 7-on-7. Rosters typically carry 10 to 14 players to allow substitutions, though the exact roster size varies by league.
Can you run the ball in flag football?
Yes, but with some restrictions. In most leagues, the quarterback cannot run the ball unless a defender rushes. Some leagues allow direct handoffs and runs from scrimmage, while others require a pass before a player can advance. NFL FLAG rules allow the QB to run once a defender crosses the line of scrimmage. Always check your league's specific rules on QB runs and handoffs.
What is the no-run zone in flag football?
The no-run zone is a 5-yard area just before each end zone and at midfield in some league formats. When the offense is inside the no-run zone, they must throw a pass. No handoffs, no QB sneaks, no direct runs. The no-run zone forces teams to use passing plays near the goal line, which keeps the game competitive and reduces congestion near the end zone.
What's the difference between NFL FLAG and rec league rules?
NFL FLAG uses standardized 5-on-5 rules, 25x70-yard fields, and specific rules like no-run zones at the 5-yard line and midfield. Rec leagues vary widely. Some play 7-on-7, some allow blocking, some have different field sizes, and some allow the QB to run freely. NFL FLAG also requires specific equipment (flag belts with three flags) and has detailed penalty rules. Rec leagues tend to be more relaxed with fewer formal penalties.
What penalties exist in flag football?
Common flag football penalties include offsides (lining up past the line of scrimmage), pass interference (contact with a receiver before the ball arrives), illegal contact (pushing, holding, or blocking), flag guarding (using your hand or body to prevent a defender from pulling your flag), and delay of game (not snapping the ball before the play clock expires). Most penalties result in a 5-yard or 10-yard gain or loss.
