U11 Soccer Rules: 9v9, Build-Out Line, Offside & More

In the United States, U11 soccer is commonly played using the 9v9 game model: nine players per team including the goalkeeper.

That national development framework is a useful baseline, but your league or tournament remains the authority for details such as match duration, substitution procedure, field dimensions and local competition rules.

Quick answer: U11 generally means players in the under-11 age group and commonly uses 9v9 in U.S. youth soccer. Check your state association and league handbook before treating any local detail as universal.

What does U11 mean?

U11 means under 11 within the competition’s age-registration system.

Age-group administration can change and competitions may group players differently, so parents should use the league’s current registration chart rather than guessing from a player’s school grade.

How many players are on the field in U11?

The widely used U.S. Soccer small-sided model places U11 and U12 in 9v9.

That means eight field players plus one goalkeeper. A league may specify the minimum number needed to start or continue.

Why 9v9?

The goal of small-sided soccer is development.

Compared with moving directly from 7v7 to 11v11, 9v9 gives players more touches, more decisions, manageable distances and clearer opportunities to learn width and depth. It bridges small-sided soccer and the full 11v11 game.

U11 field size

U11 fields are smaller than full adult fields.

Exact dimensions vary by local implementation. Use the field markings and competition rules provided by your league.

The development principle is more important than memorizing one number: the field should be large enough to create space but not so large that physical maturity overwhelms technique and decision-making.

Ball size

U11 commonly uses a size 4 ball in U.S. youth competition. Confirm the local competition handbook, especially for indoor or futsal-style events.

How long is a U11 soccer game?

Game duration can vary by competition.

Do not assume the 90-minute adult game applies. Youth leagues use shorter halves appropriate to the age group and scheduling format.

The build-out line

The build-out line is one of the most visible features of U.S. small-sided development soccer.

Its purpose is to create more opportunities for a team to play out from the back instead of having the goalkeeper send every ball long.

When the goalkeeper has the ball in hand or for a goal kick under the applicable small-sided standards, opponents retreat behind the build-out line until the ball is put into play according to the competition’s procedure.

The line also changes where offside can be called under the U.S. Soccer small-sided framework: players are not penalized for offside in the area between halfway and the build-out line.

Coaches should verify the current local implementation because referee instructions may contain operational details.

Offside in U11

U11 9v9 introduces a more advanced offside environment than younger small-sided formats.

The most important coaching lesson is not “stand on the line.” It is learning timing of forward runs, staying connected to the ball, recognizing the defender’s line and curving a run.

Defenders should learn to recover and cover rather than constantly shouting for offside.

Goalkeeper distribution

The small-sided development framework restricts some forms of long goalkeeper distribution, including punts and drop kicks in the relevant age models.

The intention is to encourage players to build possession.

Teach center backs to separate, midfielders to create angles, the goalkeeper to scan, and players to recognize when short play is not available.

Heading

Youth heading policy is a safety rule that needs current local confirmation.

U.S. Soccer and youth organizations have applied age-based heading restrictions and limitations. Because policy can be incorporated differently by member organizations and competitions, link to the current governing-body policy and the user’s local league handbook.

Coaches should never improvise around a safety restriction.

Throw-ins

A throw-in is awarded when the whole ball crosses the touchline.

At U11, many competitions use the standard two-handed technique: face the field, keep part of each foot on or outside the touchline, use both hands and deliver the ball from behind and over the head.

Local leagues may have developmental retake policies for younger groups, so confirm whether U11 uses strict turnover or a teaching retake.

Free kicks and penalties

U11 players encounter direct and indirect free kicks.

An indirect free kick requires the ball to touch another player before a goal can count. The referee signals an indirect free kick with an arm raised.

See What Is an Indirect Free Kick?.

Penalty kicks and penalty-area procedures should follow the local competition’s small-sided markings and rules.

Substitutions

Youth soccer often allows more flexible substitutions than professional competition, but the exact procedure is competition-specific.

Coaches should know when substitutes may enter, whether re-entry is allowed, where substitutions take place and roster limits.

Fouls and cards

The referee can still punish careless, reckless and excessive-force challenges. The developmental environment does not mean dangerous contact is acceptable.

A yellow card is a caution. A red card is a sending-off. Competition rules may have youth-specific consequences after a send-off.

Sliding tackles

Do not claim all U11 soccer universally bans slide tackling. Some leagues restrict it; others apply ordinary foul law.

Check the competition handbook.

Coaches should teach safe defending: arrive under control, stay on feet when possible, angle the attacker away from goal and avoid lunging.

Indoor U11 soccer

Indoor soccer can have very different rules: walls may be in play, player numbers differ, offside may not exist, restarts differ and substitutions may be on the fly.

An indoor rulebook is not a modification you should assume from outdoor U11 soccer.

Coaching priorities at U11

U11 is an ideal age for connecting individual technique to team concepts.

Priority themes include first touch, scanning, receiving with an open body shape, passing under pressure, 1v1 attacking and defending, width and depth, support angles, transition, playing out from the goalkeeper and finishing.

Avoid turning every session into formation rehearsal.

A simple 9v9 formation

A 3-2-3 is easy to understand: three defenders, two central midfielders, two wide forwards and one striker in front of a goalkeeper.

Other shapes can work. The coaching objective is to help players recognize the next problem, not memorize dots on a board.
