Choosing the right soccer ball size matters for player development. This guide explains the difference between size 4 and size 5 balls, which age groups use each, and how to order the right size in bulk.
If you're a coach ordering team balls, a club manager setting up for a new season, or a parent buying for your child's team, choosing between a size 4 and size 5 soccer ball matters more than most people realise.
Using the wrong ball size affects player development, ball control, and match fairness. Here's everything you need to know.
Size 4 vs Size 5 Soccer Ball: Key Differences
| Specification | Size 4 | Size 5 |
|---|---|---|
| Circumference | 63.5–66 cm (25–26 in) | 68–70 cm (27–28 in) |
| Weight | 350–390 grams | 410–450 grams |
| Pressure | 0.6–1.1 bar (8.7–15.9 PSI) | 0.6–1.1 bar (8.7–15.9 PSI) |
| Age Group | U8 to U12 (ages 8–12) | U13 and above (age 13+) |
| Standard Used | Youth football | Adult / professional football |
Which Age Group Uses a Size 4 Soccer Ball?
A size 4 soccer ball is the official match ball for youth football from under-8s through to under-12s. FIFA, UEFA, and most national associations mandate size 4 balls for these age groups.
The smaller circumference and lighter weight are important for younger players because:
- Children have smaller feet — a size 4 allows better first-touch control
- Lower weight reduces injury risk from heading
- Easier to kick accurately — develops proper technique before moving to the full-size ball
When to Use a Size 5 Soccer Ball
A size 5 soccer ball is the official match ball for all adult football — from U13s upward through professional level. The FIFA World Cup, Champions League, Premier League and every senior competition uses size 5.
At U12–U13 transition, coaches typically introduce the size 5 to prepare players for senior football. Some academies begin this transition at U11 to accelerate development.
What About Size 3 and Size 1?
For completeness:
- Size 3: Under-8s and younger. Also used for futsal in some associations.
- Size 2: Skills training ball. Used for footwork drills regardless of age.
- Size 1: Mini ball — promotional and keepsake only.
Buying Balls in Bulk for Your Team
Most youth clubs need 12–20 balls per team per season — training balls, match balls, and warm-up balls. Here's what to consider when placing a bulk order:
Construction Type
- Match balls: Hand-stitched or thermobonded. Higher quality, used for official matches. Size 4 match balls: typically $18–$35 each in bulk.
- Training balls: Machine-stitched, PVC outer. Durable for daily training use. Size 4 training balls: typically $8–$15 each in bulk.
Custom Club Balls
Many clubs now order custom-branded balls with their club crest, colours, and season year. This works for both size 4 (youth) and size 5 (senior) balls. Custom sublimation printing adds approximately $2–$5 per ball on orders over 50 pieces.
