Youth Soccer Ball Size Chart | Pick The Right Ball Fast

A youth soccer ball size chart takes about ten seconds to read, but picking the wrong size is a mistake that follows a young player onto the field. A ball that’s too big makes trapping and passing harder; one that’s too small teaches the wrong touch. The good news is the sizing system is simple, and once you know the player’s age, the right ball is usually one row down on the chart.

One thing to settle before you shop: your league’s rules outrank every retail chart. US Youth Soccer and AYSO both publish their own size requirements, and those are the sizes that are legal on their fields. The age ranges below are the standard consumer guidance, not a universal regulation.

The Youth Soccer Ball Size Chart By Age

Five sizes cover virtually every youth player, from toddlers doing first touches to high schoolers playing on full pitches. The table below shows the standard youth soccer ball size chart for U.S. players, with circumference and weight ranges pulled from Nike’s size-fit guide.

Weight in grams is just as useful when you’re comparing balls side by side: Size 3 runs about 300–320 g, Size 4 about 350–390 g, and Size 5 about 410–450 g. The jump between sizes 4 and 5 is the biggest, and it’s why the age cutoff between those two rows is where most parents get it wrong.

Nike frames their chart slightly differently for consumer shopping — Size 3 for under 8, Size 4 for 8–12, and Size 5 for 13+ — which lands close to the table above but treats the Size 3 band as wider. For a U.S. audience, that variance is normal: the age bands shift a year depending on whether the source is a retailer or a league.

What The Major Youth Leagues Actually Require

League rules are the final word on ball size, and they don’t always match the retail chart. U.S. youth soccer standards cluster around the same core: U6–U8 uses Size 3, U9–U12 uses Size 4, and U13+ uses Size 5. Those bands repeat across governing bodies with minor differences in how the older groups are split.

US Youth Soccer’s Rule 303 directs U6–U8 to Size 3, U10–U12 to Size 4, and U13–U19 to Size 5. AYSO’s division chart matches that shape at the edges: Schoolyard Soccer, 6U and 8U play Size 3; 10U and 12U play Size 4; 14U, 16U and 18U play Size 5.

The practical takeaway is to check your child’s specific division before you buy, because the overlap zone between sizes 4 and 5 (roughly ages 11–13) is where league rules and retail charts disagree most often. If your league hasn’t published a size, the age-based table above is a safe default.

How To Pick The Right Soccer Ball Size

Nike’s size-fit flow comes down to three steps: identify the player’s age group, match it to the charted circumference, and pick the size listed for that band. The circumference matters more than the age if the player is unusually tall or small for their year.

Three mistakes tend to trip parents up:

• Buying Size 5 too early. A full-size ball is heavier and harder to control for a 10-year-old, which slows their touch development.
• Ignoring league rules. If your division mandates Size 4, that’s the only ball that’s legal on match day.
• Using a Size 1 for matches. Size 1 balls are mainly for freestyle and foot-skills work, not standard youth games.
