Flag football is American football without tackling: a defender ends the play by pulling a flag from the ball carrier’s belt. Children can start at 4 or 5, and most youth games are 5 on 5.
The question “what is flag football” usually comes up in January, when spring sign-up forms come home or a parent volunteers to coach. This Hamco Sports guide answers it for both of you. It covers the sport in plain words, the formats, the age a child can start, what a player needs and how a new team gets going.
What is flag football?
Flag football is a non-contact version of American football. Each player wears a belt with flags hanging at the sides, and pulling one off the ball carrier ends the play. There is no tackling and, in youth leagues, no blocking. The International Federation of American Football (IFAF) governs the sport worldwide (Wikipedia, “Flag football”, checked October 30, 2026), and flag football makes its Olympic debut at the Los Angeles 2028 Games (LA28, checked October 30, 2026).
Your child’s first game will feel familiar if they have watched football. Five rules shape almost every youth game (NFL FLAG, “How to Play Flag Football”, checked October 30, 2026):
- A flag pull ends the play, and the ball is spotted where the ball was when the flag came off.
- The ball carrier may not guard or block their flags.
- The quarterback has a pass clock, 7 seconds in NFL FLAG.
- Only one forward pass is allowed per play, and it must be caught past the line of scrimmage.
- No-run zones near midfield and each end zone mean the offense must pass there.
The full rulebook is in our flag football rules guide, and our guide to flag football positions shows how a play works, spot by spot.
Flag football formats: 5v5, 7v7 and more
Flag football is played in several team sizes. Most youth leagues play 5v5, and the format decides the field and the roster you need. As of October 2026, these are the formats a parent or new coach is most likely to meet:
| Format | Players a side | Field | Who plays it |
|---|---|---|---|
| NFL FLAG 5v5 | 5 | 30 × 70 yd, including two 10-yd end zones | youth leagues, ages 5 to 17 |
| IFAF / Olympic | set by IFAF rules | set by IFAF rules | international and LA 2028 Olympic play |
| 7v7 flag | 7 | 40 × 80 yd (our field guide) | some older youth, high school and adult leagues |
| Larger rec formats | more than 7 | varies by league | some rec and adult leagues |

One name causes confusion. “7v7 football” is also a separate touch passing game, played by high school players in the off-season with no flags and no running plays. Our guide to 7v7 football explains the difference.
What age does flag football start?
Flag football starts as young as 4 or 5: NFL FLAG runs leagues for ages 5 to 17, and some local programs take 4-year-olds. Players are grouped in two-year age divisions, so a 6-year-old plays against 6- and 7-year-olds. Wichita’s NFL FLAG program, for example, runs divisions from ages 4 and 5 up to 16 and 17 (City of Wichita, NFL FLAG Wichita, checked October 30, 2026).
| Stage | Typical ages | What it looks like |
|---|---|---|
| First league | 4 to 7 | flag pulling, catching and the basic rules |
| Youth divisions | 8 to 13 | 5v5 league play with set positions |
| Teen divisions | 14 to 17 | quicker games; some leagues play 7v7 |
| High school | 14 to 18 | girls’ varsity flag in a growing number of states |
| Adults | 18 and up | rec, church and co-ed leagues |
Sources: NFL FLAG; City of Wichita NFL FLAG page; AP, May 2026 (all checked October 30, 2026). Age bands are typical; each league sets its own.
High school flag is growing among girls. In May 2026, New Jersey became the 18th state to sanction girls’ flag football as a varsity sport, and pilot programs run in more states (AP, May 5, 2026). Your state’s high school association can tell you whether your daughter’s school may field a varsity team.
What does a flag football player need?
A flag football player needs very little equipment: a mouthguard, the right shoes, a pair of shorts and a team jersey. In NFL FLAG, the mouthguard is the only protective gear, and metal cleats are not allowed, so molded cleats or sneakers work (NFL FLAG equipment page, checked October 30, 2026).
- Mouthguard: required in NFL FLAG.
- Shoes: sneakers or molded cleats, never metal spikes.
- Shorts: NFL FLAG asks for shorts without pockets.
- Jersey: a numbered team jersey (who supplies it is below).
- Belt and flags: supplied by the league in NFL FLAG.
Who supplies the jersey depends on the league. NFL FLAG says “every player also receives a team jersey upon registration,” along with the belt and flags. Independent rec leagues, schools, churches and tournament teams usually order their own. The full player and team list is in our guide to what to wear for flag football.
How to start a flag football team
Starting a flag football team takes five things: players, a league or tournament, a field slot, a coach and matching jerseys. Five players are on the field in 5v5, and a roster of 8 to 10 gives you substitutes for every game. If you are setting up a whole league, our guide on starting a flag football league covers it step by step.
How Hamco Sports handles a new team’s jerseys:
- No minimum order, so 7 players or 70 is fine.
- Youth and adult sizes cost the same, from $46.99 a player for 1 to 24 jerseys.
- No setup fee. Sublimated names and numbers are included, and tackle twill is $5 per name and $5 per number.
- A league ordering for several teams gets the tier of all its jerseys combined.
- If your team has no logo yet, our designers create one at no extra cost.
Our flag football jerseys page shows the jersey styles, plus the shorts and full uniform sets that go with them.
Frequently asked questions
Is flag football a contact sport?
No. Flag football is a non-contact sport: a flag pull replaces the tackle, and youth leagues don’t allow blocking. A mouthguard is still required in NFL FLAG. The contact rules for each format are in our flag football rules guide.
How many players are on a flag football team?
In NFL FLAG youth leagues, five players from each team are on the field at once, because the game is 5 on 5. Most new coaches carry 8 to 10 players, which covers absences and gives everyone a rest during the game. Some older youth and adult leagues play 7 on 7 and need a bigger roster. Hamco Sports has no minimum order, so any roster size can order jerseys.
Is flag football hard for beginners?
Flag football asks less of a beginner than tackle football: no pads, no tackling and no blocking. A new player needs a mouthguard, shoes and a jersey, and the first skills are catching, running and pulling a flag. Players are grouped in two-year age divisions, so a beginner plays against children of the same age. Plays and positions come later, as they move up through the divisions.
Why is the NFL playing flag football?
The NFL runs its own youth flag program, NFL FLAG, with leagues for ages 5 to 17. Flag football also makes its Olympic debut at the Los Angeles 2028 Games, with a men’s and a women’s tournament (LA28). That Olympic spot is a big reason the sport gets so much attention now.
Can girls play flag football?
Yes. Youth flag football leagues are usually co-ed, so girls and boys play on the same teams. Girls’ varsity flag is now a high school sport in a growing number of states, and New Jersey became the 18th state to sanction it in May 2026 (AP). Our girls’ flag football guide covers teams, rules and seasons.
