Snug, level, and it does not move
The chart gets you to the right size. The fit decides whether the helmet actually protects — and a helmet two sizes too big protects considerably less than a correctly fitted one.
- Sit about an inch above the eyebrows and level — not tipped back, which is how most kids wear it and how it fails on impact.
- It should not rotate when you try to turn it left and right with the head still.
- The chin strap does real work. A loose strap lets the helmet roll forward on a fall. Buckle it, snugly.
- No gaps at the temples. Pads inside the shell take up room — remove them as the head grows rather than buying a bigger helmet.
The youth batting helmet size chart
Measure the head — it is a better predictor than age, and youth heads vary widely at every age.
| Head circumference | Typical age | Helmet size | Liner pads |
|---|---|---|---|
| 19" – 20" | 3–5 | 6⅜ – 6½ | thickest insert |
| 20" – 21" | 5–7 | 6½ – 6⅝ | standard |
| 21" – 22" | 7–9 | 6⅝ – 6¾ | standard |
| 22" – 23" | 9–11 | 6¾ – 7 | standard or thin |
| 23" – 24" | 11–13 | 7 – 7⅛ | thin insert |
| 24" and up | 13+ | 7⅛ – 7¼ | check adult sizing |
Sizes are US hat sizes converted from head circumference. Manufacturers differ slightly — the measurement matters more than the number on the box.
Measuring the head correctly
Two minutes with a soft tape measure removes all the guesswork.
The method
- Run a soft tape measure about an inch above the eyebrows.
- Continue around the widest part of the back of the head.
- Keep it level all the way round — a tape that dips at the back reads small.
- Take it twice. If the two readings differ, measure again.
No tape measure?
- Use a string, mark where it meets, then lay it against a ruler.
- Or use a soft strip of paper the same way.
- Do not use the kid's current hat size — baseball caps run loose and are cut differently.
Ear flaps, face guards, and the dual-flap question
Which flaps a helmet needs is a league decision, not a purchase preference. Check before you buy.
- Two flaps or one: many leagues require an ear flap on the pitcher's side at minimum; some require both.
- Dual-flap helmets can swap sides, which matters if your kid bats left-handed one season and right-handed the next.
- Face guards are required by age in a growing number of leagues — increasingly from 10U down, and sometimes up through 12U.
- Attach only the guard designed for that helmet. Third-party guards can void the certification.
What NOCSAE means, and why it matters
A helmet without a recognised safety certification is a hat with a hard shell.
- Look for the NOCSAE mark on the shell or label — it is the standard youth baseball and softball helmets are tested against.
- Leagues require it. Most publish an approved list; some require a specific certification for certain age groups.
- Check the date. Older helmets may have been tested against an earlier version of the standard.
- Second-hand helmets: acceptable only if you know its history. An unknown helmet has unknown impact history.
The four times a helmet must be replaced, not repaired
Helmets are single-impact items by design. The foam does its job once.
- After any direct hit to the shell — a pitched ball, a bat, a fall onto concrete — even with no visible damage.
- If it is cracked, split, or dented anywhere on the shell or the ear flaps.
- If it no longer fits and the pads cannot take up the difference.
- If the certification label is gone or unreadable — a league may reject it regardless of condition.
Measure an inch above the eyebrows, buy the size that matches the measurement, buckle the chin strap, and replace the helmet the moment it takes a real hit. A correctly fitted certified helmet is the cheapest serious safety purchase you will make all season.
