How Big Is a U12 Soccer Goal? | Youth 9v9 Dimensions

A U12 soccer goal is typically 7 feet tall by 21 feet wide at the maximum, sized for 9v9 play.

If you’re sizing a goal for a U12 player, the range you’ll see most often comes from U.S. Youth Soccer: no larger than 7 feet high by 21 feet wide, with a recommended size of 6.5 by 18.5 feet. These dimensions exist because U12 is the bridge between small-sided games and the full 11v11 field, and the goal needs to match the players’ physical scale.

The Official U.S. Youth Soccer Guidance

U.S. Youth Soccer’s Player Development Initiatives document, published in 2017, sets the standard for U11/U12 age bands. The document states that goals should be no larger than 7 feet in height by 21 feet in width for this age group, which plays 9v9 soccer on a smaller field than the adult version.

The same document goes further, recommending 6.5 feet by 18.5 feet as the ideal size “based on players’ age and ability.” That’s the number most leagues and clubs aim for when they have the choice, even though the larger 7×21 is technically allowed.

Here’s the key distinction to remember:

• 7′ H x 21′ W — the maximum permitted size
• 6.5′ H x 18.5′ W — the recommended size for most U12 players

Both fit within the U.S. Youth Soccer framework, and neither matches the adult goal you see on TV.

How U12 Goals Compare to Full-Size Goals

Full-size adult goals are 8 feet high by 24 feet wide, used for 11v11 play from U13 upward. The difference matters more than the few extra inches suggest — a 24-foot-wide goal is roughly 14% wider than the U12 maximum, and the extra height changes how young goalkeepers cover the frame.

Regulation adult dimensions are measured between the inside of the posts and under the crossbar. IFAB’s laws of the game specify 7.32 meters (8 yards) between posts and 2.44 meters (8 feet) to the underside of the crossbar. Youth goals follow the same inside-edge measurement convention.

When the Size Can Vary

U.S. Youth Soccer’s guidance is exactly that — guidance. Individual leagues, tournaments, and local organizations can set their own standards, and some do. Before you buy or build, confirm the required size with the league your child plays in, since a goal that’s too large for the division may not pass inspection on game day.

Common Mistakes to Avoid

The most frequent error is assuming U12 uses a full-size 24 x 8 goal. It doesn’t — that size belongs to 11v11 play from U13 up. The second mistake is mixing up maximum and recommended dimensions, which leads to buying a 7 x 21 goal when the league expected 6.5 x 18.5. Always read the league’s rulebook before spending money.

Measuring matters too. Youth goals are measured the same way as adult ones: from the inside of one post to the inside of the other, and from the ground to the underside of the crossbar. A goal that looks close but is off by a few inches can still be out of compliance.
