Soccer Ball Size by Age: The Complete Guide

Choosing the right soccer ball size by age matters more than you'd think: a ball that's too big or too heavy hurts a child's technique and can even cause injury. The rule is simple — size 3 for the little ones, size 4 for kids, size 5 for teens and adults. This guide gives you the full size chart, the FIFA standards and the benchmarks to choose without second-guessing.

At Soccer Sport Fitness, we've been advising players, coaches and parents for years. This guide is based on official federation recommendations and our in-store experience.

What size soccer ball by age?

Soccer ball size is chosen first by the player's age and category. Using the right size helps a child develop technique, control the ball and play safely. You can shop by size in our soccer balls collection.

• Size 3 — ages 3 to 7 (U8 and under): the introduction ball and the youth ball of choice, lighter and smaller, perfect for first kicks.
• Size 4 — ages 8 to 12 (U9 to U12): the junior ball for kids and pre-teens; it's also the size used in futsal.
• Size 5 — ages 13 and up (U13, U15 and older): the official match ball, for teens and the adult ball.

These categories follow federation standards. In Canada, most youth leagues apply these sizes by age group — check your child's league rules if you're unsure.

My child is between two age groups

Is your child 7 or 8 and stuck between a size 3 and a size 4? As a rule, stay with the smaller ball: lighter, it makes it easier to develop technique and control. A junior ball that's too big pushes a child to “boot” the ball rather than master it. Make an exception, though, if their league already requires the larger size — league rules always win. When in doubt, we'll help you in store.

Here are the official specifications (circumference and weight) for the three standard sizes:

What are the FIFA standards for soccer balls?

An official or certified ball meets FIFA standards. There are three certification levels, from most accessible to most demanding:

• FIFA Basic — the certified entry level, for training and recreational play.
• FIFA Quality — a reliable ball for amateur competition and the league ball.
• FIFA Quality Pro — the highest standard, reserved for top-level match balls.

To earn these certifications, a FIFA ball must pass a series of lab tests:

• Circumference — meeting the official measurements (68-70 cm for a size 5).
• Weight — staying within the regulation range (410-450 g in size 5).
• Sphericity (shape) — staying perfectly round, even after thousands of strikes.
• Rebound — a consistent bounce from one area of the ball to another.
• Water absorption — not getting heavier in the rain.
• Pressure loss — holding its inflation pressure over time.

In short: the higher the certification, the straighter the ball flies and the better it keeps its shape. For a competition or league ball, aim for at least FIFA Quality; for training, a FIFA Basic (or a good training ball) is plenty.

Sizes 1 and 2 and special balls

Beyond the three playing sizes, you'll come across other formats:

• Size 1 (mini ball): a small display and skills ball, also popular as a souvenir. Great for working on your touch at home. See our mini soccer balls.
• Size 2: a technical training ball, mostly used for control and juggling.
• Futsal ball: usually a size 4 with reduced bounce, built for indoor play on hard surfaces. See our futsal balls.

Match ball or training ball?

At the same size, not all balls are equal. The match ball has a more refined build (often thermally bonded) for a steady flight and a premium touch — ideal on match days. The training ball, more durable and affordable, handles daily repetition. The major ball brands — Select, adidas, Nike, Puma, Molten, Umbro — all offer FIFA-certified models. In our shop, Select is a reference, from training ball to match ball.

Caring for and replacing your soccer ball

How to measure a soccer ball

Size corresponds to circumference: measure around the ball with a soft tape at its widest point. A size 5 is 68-70 cm, a size 4 about 63.5-66 cm and a size 3 about 58-61 cm.

When to replace a worn ball

Replace your ball when it shows these signs: it deforms or is no longer perfectly round, it loses pressure too fast, its seams open up, or its surface is peeling and slippery. An outdoor ball takes far more abrasion on asphalt or turf than an indoor ball — ideally keep one for each use.
