Saturday, 9 a.m. A dozen first-graders in oversized jerseys and flag belts line up on a field the size of a backyard. Half of them run the wrong way on the first play, and everybody cheers anyway. A few years later the same parents are asking harder questions: is my kid ready for tackle? How much hitting happens in practice? What about concussions and the August heat? This page answers them. Here is youth football in plain words: the ages and formats, flag vs tackle, the contact limits and heat rules that good programs follow, concussion laws, parents’ most common questions, and the basics of college recruiting.

For an overview of the sport at every level, start at our football hub.

Ages and formats: from flag to 11-player tackle

USA Football, the sport’s national governing body, lays out a step-by-step path in its Football Development Model: flag football first, then a smaller tackle game, then the full 11-player game. Big programs follow a similar path. Pop Warner, for ages 5 to 16, offers flag, Rookie Tackle and 11-player tackle.

Format	Who plays	What it looks like
Flag football	NFL FLAG: ages 4 to 17	5v5 on a 70 × 30-yard field, no tackling, blocking or diving; a mouthguard is the only protective gear
Rookie Tackle (USA Football)	A bridge between flag and full tackle	6 to 8 players a side on a field about 40 × 35 yards, no three-point stance, no special teams, everyone learns every position
Youth 11-player tackle	USA Football’s youth guidelines cover about ages 6 to 14	Full pads, age and often weight limits set by each league
High school	Grades 9-12	NFHS rules; 11-player, plus 6-, 8- and 9-player football at small schools and girls flag football in a growing number of states

Flag is the biggest door into the sport: NFL FLAG says it serves more than 830,000 athletes in 2,000+ leagues. The full rules for each format are on our football rules page, and the organizations behind them on football leagues and associations.

Flag vs tackle: what the research says

The clearest numbers come from CDC researchers who put sensors on youth players aged 6 to 14. Tackle players took about 15 times more head impacts than flag players in practices and games, and 23 times more high-magnitude ones. Over a season, the median tackle player had 378 head impacts; the median flag player had 8. The researchers concluded that flag or non-contact football may be a safer option for players under 14 to reduce head impacts and concussion risk.

The American Academy of Pediatrics (AAP) doesn’t set a national starting age for tackling. Its 2015 policy statement asks for zero tolerance of illegal, head-first hits, more non-tackling leagues for kids who want to play without tackling, and athletic trainers on the sidelines. It also notes a trade-off: kids who learn to tackle later may meet it when they’re bigger and stronger. So the choice is a family one; the checklist below can help.

Practice contact limits: what good programs follow

USA Football’s 2021 recommendations for youth tackle football, built on guidelines endorsed by the American College of Sports Medicine, the American Medical Society for Sports Medicine and the National Athletic Trainers’ Association, are a good yardstick for any league:

• Full contact (contact at competitive speed, whether or not players go to the ground): no more than 30 minutes on any day, 75 minutes a week in preseason and 60 minutes a week once games begin.
• No full contact on back-to-back days, including the day after a game.
• One full-contact game or live scrimmage a week, at most.
• Banned drills: Oklahoma, Bull in the Ring (King of the Circle), straight-ahead board drills and pod drills with no run or pass read.
• Two-point stance for all players in flag and modified tackle, and encouraged for offensive players in older youth tackle, because three- and four-point stances bring more head impacts.

USA Football also teaches five levels of contact: Air (no contact), Bags, Control (a set winner, players stay up), Thud (full speed to the moment of contact, players stay up) and Live Action (the only level where players go to the ground). Pop Warner limits contact to 25% of practice time, dropped kickoffs for its youngest divisions in 2016 and removed the three-point stance for players about 10 and under in 2019. In high school, an NFHS task force recommended in 2014 that full contact be limited to two or three practices and 60 to 90 minutes a week, and most states adopted limits of their own.

Coach training. USA Football’s youth coach certification, which grew out of its Heads Up Football program and is accredited by the U.S. Center for Coaching Excellence, covers tackling and blocking technique, concussion recognition, heat and hydration, and sudden cardiac issues. Many leagues require it every year for every coach on the field. Ask yours.

Heat acclimatization: the first two weeks

From 1982 to 2022, 63 of the 67 exertional heat stroke deaths in US secondary school sports were in football, and August was the peak month. Most heat deaths happen in the first days of practice, when players do too much, too soon, in too much gear. That’s why the rules phase it in:

• High school (NATA guidelines): a 14-day period. Days 1-5: one practice a day, no more than 3 hours. Helmets only on days 1-2; helmets and shoulder pads on days 3-5, when football players may start hitting sleds and dummies. Full pads and full contact no earlier than day 6, and from then on a double-practice day must be followed by a single-practice or rest day. NATA strongly recommends an athletic trainer on site.
• Youth tackle (USA Football): a 10-14 day period. Days 1-2: no more than 90 minutes, helmets only, no player-to-player contact. Days 3-4: up to two hours in helmets and shoulder pads, no full contact. Full pads and full-contact drills can start on days 5-6. No two-a-days ever, and kids should be able to drink at any time.

On very hot days, programs should add breaks or move practice to cooler hours (USA Football suggests before 10 a.m. or after 6 p.m.). Call 911 for confusion, collapse or a seizure; for exertional heat stroke, NATA recommends rapid cold-water immersion on site by trained staff. Our football game-day page covers fluids and electrolytes.

Concussion laws: what every parent should know

In 2006, Zackery Lystedt returned to a middle school football game after a concussion and suffered a brain injury. Washington’s Lystedt Law followed in 2009, and by 2014 every state had a youth concussion law built on the same three parts: education before the season, removal from play when a concussion is suspected, and clearance by a health care professional before returning. Details vary by state, so ask your league or school for its policy.

The CDC’s HEADS UP advice is simple: when in doubt, sit them out. Watch for a child who seems dazed, confused or slow to respond, or who complains of headache, dizziness, nausea, blurry vision or sensitivity to light or noise. Keep them out for the rest of the day and until a health care provider clears them; return to play happens in steps. Call 911 for danger signs like a worsening headache, repeated vomiting, seizures or unusual drowsiness. Football has the highest concussion rate of 20 high school sports in one national study, so this matters. Our football injuries page goes deeper.

A parents’ checklist before tackle football

• Are all coaches certified (for example, USA Football’s youth coach certification), and is a coach trained in concussion and heat response at every practice?
• What are the contact limits, and does the league use the levels of contact?
• Is there a heat-acclimatization plan, water at all times, and an athletic trainer or medical person at games?
• Are helmets certified to the NOCSAE standard and fitted by someone trained to do it?
• Does your child have a mouth guard? NFHS rules require one in high school, and NFL FLAG requires one in flag.
• Has your child had a preseason physical? AAOS recommends one.

Recruiting basics: from high school to college football

• Register with the NCAA Eligibility Center if you’re aiming for Division I or II. Division I needs 16 approved core courses and at least a 2.3 core-course GPA, with 10 of those courses (7 in English, math or science) done before senior year. Division II also needs 16 core courses, with a 2.2 GPA. Work with your school counselor early.
• Contact rules: in Division I football, college programs can’t send recruiting materials, texts or emails before September 1 of a player’s junior year. Other dates (calls, visits, signing) differ by division and change often, so check the current NCAA recruiting calendar.
• Think beyond FBS. There are 128 FCS, 160 Division II, 244 Division III and 96 NAIA football teams, plus junior colleges. Division III gives no athletic scholarships, but most of its athletes get academic or need-based aid.
• Girls: women’s flag football is a varsity sport in the NAIA and an NCAA emerging sport since January 2026.

What helps most: grades, game film and short, personal emails to coaches at schools that fit you. The strength and speed side is on our football training page, and some players track their sprint work with a GPS vest (see our GPS trackers for team sports guide).

The right gear for young players

Three things every young player can use: a mouth guard that fits, a ball sized for small hands, and a flag set for backyard games. The Shock Doctor Gel Max comes in youth and adult sizes, with a liner that molds to the teeth and a detachable helmet strap. The Wilson NFL Super Grip in junior size is made for ages 9-12, Wilson says. And the Franklin Sports 10-player flag set has belts that fit kids and adults up to a 46-inch waist. Prices change often. These are what we saw at a major retailer in October 2026.

Pads, helmets and cleats are on our football gear page. For tired legs after a tournament day, see our recovery shoes guide, and for another sport’s take on kids and safety, see youth soccer.

Youth football questions from parents

What age should kids start tackle football?

There’s no single national age. NFL FLAG starts at 4, USA Football’s tackle guidelines cover about ages 6 to 14, and the AAP leaves the decision to families while asking for more non-tackling options. CDC research found tackle players aged 6 to 14 took about 15 times more head impacts than flag players, which is why many families wait.

Is flag football safe?

It’s much lower in head impacts: a median of 8 per season in the CDC study, against 378 in tackle. Sprains and bumps still happen, so warm-ups, mouthguards and trained coaches still matter.

How much hitting should there be in youth practice?

USA Football recommends no more than 30 minutes of full contact a day, 75 minutes a week in preseason and 60 minutes a week in season, never on back-to-back days. If your program hits more than that, ask why.

What should I do if I think my child has a concussion?

Take them out of play right away and keep them out for the rest of the day. Have a health care provider check them, and only return to sport, step by step, after the provider clears them. Call 911 for danger signs like a worsening headache, repeated vomiting or a seizure.

When can college coaches contact my child?

In Division I football, recruiting materials, texts and emails can start on September 1 of junior year. Coaches can still watch your child play before that, and the rules differ in Division II, Division III, the NAIA and junior colleges, so check the current NCAA calendar.

Can girls play football?

Yes. Girls flag football is a high school sport in a growing number of states, with 68,847 players in 2024-25, and a college sport in the NAIA and NCAA. In 2024-25, 4,837 girls also played on 11-player high school teams.
