Youth Soccer Rules: The Complete Guide
Everything parents and coaches need to know about youth soccer. Small-sided formats, field sizes, game length, build-out lines, heading rules, and age-specific modifications from U6 through U14.
Youth soccer is the most popular youth sport in America, with millions of kids playing every season. But the rules aren't the same as what you see on TV. Youth soccer uses smaller fields, fewer players, shorter games, and a whole set of age-specific modifications designed to help kids develop skills and have fun. If you're a parent or first-time coach, the differences can be confusing.
This guide covers youth soccer rules for every age group from U6 through U14. We'll explain small-sided formats, field sizes, game length, the build-out line, heading restrictions, offsides, substitutions, and everything else you need to know before game day.
For specific field measurements by age group, see our soccer field dimensions guide. And to plan around the season calendar, check out when does soccer season start.
Small-Sided Game Formats
How the game scales by age group.
US Soccer mandates small-sided games for younger players. Instead of jumping straight into 11v11 on a full-size field, kids start with smaller teams on smaller fields and gradually work up. The reasoning is simple: smaller games mean more touches on the ball, more decisions, and more time actually playing instead of standing around waiting for the ball to come your way.
| Age Group | Format | Field Size (approx) | Goal Size |
|---|---|---|---|
| U6 | 3v3 (no GK) | 25 x 15 yards | 4 x 3 ft pugg goals |
| U8 | 4v4 (no GK) | 35 x 25 yards | 4 x 6 ft goals |
| U10 | 7v7 (with GK) | 55 x 35 yards | 6.5 x 18.5 ft goals |
| U12 | 9v9 (with GK) | 70 x 45 yards | 7 x 21 ft goals |
| U14+ | 11v11 (with GK) | 100 x 60 yards | 8 x 24 ft goals (regulation) |
Field sizes can vary by league. For exact measurements including penalty areas and goal box dimensions, check out our soccer field dimensions guide.
Game Length and Structure
How long games last at each age group.
Youth soccer games are shorter than adult games, and many younger age groups use quarters instead of halves to create natural breaks for coaching, hydration, and substitutions.
| Age Group | Game Format | Total Playing Time |
|---|---|---|
| U6 | 4 x 8-minute quarters | 32 minutes |
| U8 | 4 x 10-minute quarters | 40 minutes |
| U10 | 2 x 25-minute halves | 50 minutes |
| U12 | 2 x 30-minute halves | 60 minutes |
| U14 | 2 x 35-minute halves | 70 minutes |
| U16+ | 2 x 40-minute halves | 80 minutes |
Most youth games do not have stoppage time (extra time added for injuries and delays). The clock runs continuously. Half-time breaks are typically 5 to 10 minutes. Some leagues use quarters at U10 and younger to give coaches more planned substitution windows.
The Build-Out Line
Giving goalkeepers space to play the ball on the ground.
The build-out line is one of the most important youth-specific rules in soccer. It applies to U9 through U12 age groups and fundamentally changes how the game restarts from the goalkeeper.
How the Build-Out Line Works
- Location: The build-out line is marked across the width of the field, halfway between the top of the penalty area and the midfield line.
- When it applies: On goal kicks and when the goalkeeper has possession of the ball (after a save or picking up a back pass).
- What happens: The opposing team must retreat behind the build-out line until the ball is put into play. They cannot press the goalkeeper or the defenders in that zone.
- Ball in play: The goalkeeper can play the ball at any time. They don't have to wait for the opponents to retreat. But the opposing team must be retreating.
- Punting: The goalkeeper is NOT allowed to punt (drop-kick) the ball when the build-out line is in effect. They can throw it or play it on the ground. This prevents teams from bypassing the build-out entirely with a long punt.
Why This Rule Exists
Without the build-out line, goalkeepers at young ages would just boot the ball as far as possible, and the other team would press high to steal it. Neither team would develop the habit of playing out of the back. The build-out line creates space for defenders and goalkeepers to pass the ball and start building attacks from their own end. It develops the possession skills that matter at higher levels of soccer.
Heading Restrictions
When players can and can't head the ball.
US Soccer implemented heading restrictions in 2016 as part of its Player Safety Campaign. The research is clear: repeated heading in young players carries concussion risk, and developing brains need protection. Here's how the rule breaks down by age.
U11 and Younger
No heading allowed in games or practice. If a player heads the ball during a game, the opposing team gets an indirect free kick from the spot of the header.
U12 to U13
Heading is introduced in practice only, limited to approximately 30 minutes per week. Heading in games is typically allowed at U13 (check your league). Coaches should teach proper heading technique gradually.
U14 and Older
Full heading is allowed in both games and practice. Players at this age should have been introduced to proper heading technique during the U12-U13 transition period.
This is a US Soccer policy. Some international federations have different age thresholds. If you're coaching in a league affiliated with a different federation, verify their specific heading policy.
Offsides, Referees, and Other Rules
Age-specific rule modifications you need to know.
Offsides
No offsides at U8 and younger. Offsides is introduced at U9 or U10 (varies by league). Once it's in play, the standard FIFA offsides rule applies: a player is offsides if they are closer to the opponent's goal line than both the ball and the second-to-last defender at the moment the ball is played to them.
Referee Format
Small-sided games (U6 to U10) typically use 1 referee on the field. When teams move to 9v9 (U12), a 3-referee system (1 center referee, 2 assistant referees on the sidelines) is introduced. The 3-referee system is standard for all 11v11 games.
Substitutions
Youth soccer allows unlimited substitutions at most levels. At younger ages (U6 to U10), subs can typically happen at any stoppage. At older ages, substitutions are limited to specific stoppages: goal kicks, after a goal, at halftime, and on your own throw-in (varies by league). Some leagues allow subs on the opponent's throw-in too.
Slide Tackling
Many rec leagues ban slide tackling at all youth ages. Competitive leagues typically allow it starting at U10 or U12. A legal slide tackle must contact the ball first and cannot endanger the opponent. Any reckless or dangerous tackle is a foul, regardless of whether the ball was won.
Goal Kicks
At U9 through U12, goal kicks are subject to the build-out line rule (opponents must retreat). The ball is in play once it's kicked and clearly moves. In younger ages without the build-out line, goal kicks follow standard rules. At U14+, goal kicks follow the full Laws of the Game.
Throw-Ins
Throw-ins follow standard rules at all levels: both feet on the ground, ball delivered from behind and over the head with both hands, facing the field. At younger ages, referees may allow a re-throw if the technique is wrong rather than awarding the throw to the other team.
Playing Time and Sportsmanship
Making sure every kid has a good experience.
Youth soccer, especially at the recreational level, has strong guidelines around equal playing time and conduct. The goal is player development, not winning at all costs.
Equal Playing Time (Rec Leagues)
Most recreational leagues require coaches to give every player at least 50% playing time, and many push for equal playing time across the roster. Some leagues mandate that every player plays at least one half or three quarters. Competitive and travel leagues have more flexibility, but many still enforce minimum playing time rules to ensure development.
No Score Keeping (Youngest Ages)
Many leagues don't keep score at U6 and U8. Some don't even keep standings. The emphasis is on learning basic skills (dribbling, passing, shooting) and having fun. Whether your league keeps score or not, the focus at these ages should be on participation and improvement, not results.
Sportsmanship and Conduct
Most youth soccer leagues have conduct policies for players, coaches, and parents. Yellow and red cards follow FIFA rules: a yellow card is a caution (two yellows in one game equals a red), and a red card means the player is sent off and typically suspended for the next game. Parent and coach misconduct can result in ejection from the facility. Many leagues use a "Good Sportsmanship" policy with escalating consequences.
Position Rotation
At recreational levels, coaches are encouraged to rotate players through different positions so everyone gets experience. Don't put your best athlete at striker every game and your smallest player at goalkeeper every week. Let kids try different positions, especially at U6 through U10, when they're still figuring out what they enjoy.

Frequently Asked Questions
What are the rules for youth soccer?
Youth soccer rules adapt the game to be age-appropriate. Young players (U6 to U8) play small-sided games (3v3 or 4v4) on small fields with shorter halves and no goalkeepers. As kids get older, the field grows, more players are added, and rules like offsides and heading are introduced. US Soccer mandates no heading until U13, uses a build-out line for U9 to U12, and requires small-sided games through U12. The goal is maximum touches on the ball and fun at every age.
What is the build-out line in youth soccer?
The build-out line is a line drawn across the field halfway between the top of the penalty area and the midfield line. It's used in U9 through U12 age groups. When the goalkeeper has the ball (from a save or goal kick), the opposing team must retreat behind the build-out line until the ball is put into play. This gives the goalkeeper's team space to build up play from the back instead of just kicking the ball long. It encourages passing and possession from a young age.
When can kids start heading the ball in soccer?
Under US Soccer's Player Safety Campaign, heading is not allowed in games or practice for players U11 and younger. Limited heading is introduced in practice starting at U12 and U13 (approximately 30 minutes per week). Full heading is allowed starting at U14. If a player heads the ball during a game before the allowed age, the opposing team is awarded an indirect free kick from the spot of the infraction. This policy was implemented to reduce the risk of concussion and head injuries in young players.
How many players are on a youth soccer team?
The number of players on the field depends on the age group. U6 plays 3v3, U8 plays 4v4, U10 plays 7v7, U12 plays 9v9, and U14 and older play 11v11 (full-sided). These numbers reflect US Soccer's recommended formats. Roster sizes are larger to allow for substitutions: a U10 team might carry 10 to 12 players, while a U14 team might carry 15 to 18. The small-sided formats at younger ages give every player more touches and more involvement in the game.
Is there offsides in youth soccer?
Offsides is not enforced in most youth soccer games until U9 or U10, depending on the league. At U8 and younger, where games are 3v3 or 4v4 on small fields, there is no offsides. Introducing offsides too early on small fields would restrict play unnecessarily. Most leagues begin enforcing offsides when teams move to 7v7 or larger formats, which gives players enough field space for the rule to make sense.
How long are youth soccer games?
Game length increases with age. U6 games are typically four 8-minute quarters. U8 games are four 10-minute quarters. U10 games are two 25-minute halves. U12 games are two 30-minute halves. U14 games are two 35-minute halves. U16 and older play two 40-minute halves (approaching the full 45-minute halves used in professional soccer). Some leagues use quarters at younger ages to create natural breaks for coaching and hydration.
Can you slide tackle in youth soccer?
It depends on the league and age group. Many recreational youth leagues prohibit slide tackling at all ages for safety reasons. Competitive and travel leagues typically allow slide tackling starting at U10 or U12, as long as the tackle is made fairly (contacting the ball first, not the player). US Soccer's Laws of the Game don't specifically ban slide tackles, but local leagues often add this restriction at younger ages. If a slide tackle is deemed dangerous or reckless, it's a foul regardless of age or league rules.
