How Youth Soccer Rules Differ from the Pros

Novice parents will start to notice the youth‑specific tweaks to the normal (pro/FIFA) game: field size/players, substitutions and playing time, offsides/build‑out, heading, goal kicks and keeper rules, and safety/fouls.

Field size, team size, and game length

Younger ages play on smaller fields with fewer players (3v3, 4v4, 7v7, 9v9) before progressing to full 11v11 around age 13.
Game length is shorter for younger kids (often 2 x 20–30 minutes) and increases toward older ages, but still may be slightly shorter than adult 45‑minute halves.

These are big differences from pro/international games, which are always 11v11 on full‑size fields with 45‑minute halves.

Substitutions and

playing time

Youth leagues usually allow unlimited substitutions, typically on stoppages such as throw‑ins, goal kicks, or kick‑offs, instead of the strict 3–5‑sub limits seen in professional play.
Many recreational leagues have a “minimum playing time” expectation (often around 50% of the game) so every child plays, which does not exist in pro soccer.
Competitive travel/club teams may be closer to adult rules on subs and do not guarantee equal playing time.

Offside and build‑out lines

Very young formats (3v3, 4v4, sometimes 7v7) often do not use offside at all, even though it exists in the adult game.
In mid‑age small‑sided games (commonly 7v7 or 9v9), many leagues add a “build‑out line”:
- On goal kicks or when the keeper has the ball, opponents must retreat behind this line to let the team play out from the back.
- Offside may only be called between the build‑out line and the goal line, not in the entire half as in pro games.
By full‑sided 11v11, offside is usually the standard FIFA version that parents see on TV.

Heading and safety‑driven changes

A key surprise for parents: in the U.S., players 10 and under are not allowed to head the ball in games or practices; deliberate headers result in an indirect free kick.
Many leagues limit or strongly discourage heading at 11–12 as well, ramping up only at 13+; heading is fully allowed for adults and in international play.[10][2]
Youth rules also strongly emphasize safety on contact: charges, slide tackles from behind, and shoulder challenges are often called more tightly than in pro matches.

Goalkeepers, goal kicks, and pass‑back

Youngest age groups may play with no goalkeeper at all; a keeper is added as kids get older.
In small‑sided ages, keepers often cannot punt or drop‑kick the ball; they must roll or pass it out on the ground to encourage building from the back, unlike pros who can punt long.
The classic “back‑pass rule” still applies once there are keepers: a keeper may not pick up a deliberate kick from a teammate’s foot (restart is an indirect free kick), same as in the adult game.
Goal kicks for younger ages are often retaken if not done correctly and opposing players must stand farther away, which is more forgiving than in professional matches.

Free kicks, penalties,

and restarts

Youth games use the same idea of direct vs indirect free kicks, but younger ages sometimes treat all fouls as indirect to avoid scary close‑range shots.
Walls are usually set closer (e.g., 5–8 yards instead of the adult 10 yards) on small fields.
Some small‑sided formats have no penalty kicks at all; fouls in the penalty area may restart with an indirect free kick from outside the goal box, unlike the penalty‑spot shots seen in older age groups and pro games.

Cards, discipline, and general culture

Referees at younger ages often avoid yellow/red cards, choosing to explain and manage behavior instead, even though the card system is the same as in adult rules.
Many leagues have sportsmanship and “silent sideline” expectations for parents and coaches that go well beyond anything codified in professional or international soccer.
