Batting helmet size chart: how to measure your kid's head and match it to a shell

Helmets are sold by hat size, kids' heads are measured in inches, and the makers each cut their shells differently. The measuring method, the conversion table, every youth shell range we could find on a maker's page, the wobble test, and one helmet per size band.

How to measure

Rawlings' instruction, printed on its helmet pages: “For helmet size, measure the circumference of the head just above the ears and refer to the chart.” Use a soft sewing tape (or a string and a ruler), keep it level across the forehead about an inch above the eyebrows and just above the ears, snug but not tight, and read the inches to the nearest eighth. Measure twice; a kid moves.

23 1/2 in7 1/2
24 in7 5/8

Hat size is circumference in inches divided by pi, rounded to the nearest eighth; the same arithmetic as Rawlings' own table (which pairs, for example, 21 1/2–22 in with 6 7/8–7).

Hat-size ranges quoted from the Rawlings helmet size tables (on the CoolFlo Max page) and the Easton Z50 and Pro Max spec pages. Circumference columns are our conversion. The RX2 is sold as Junior and Senior; Rawlings' page does not print the range, so use the Mach/Velo Junior and Senior rows as the guide and check the fit.

The fit test

  1. Helmet on level, brim about an inch above the eyebrows.
  2. Ear holes over the ears.
  3. Kid shakes his head hard: the helmet should move with the head, not slide on it.
  4. Kid bends forward and looks at his feet: it should not fall off.
  5. Two fingers should not fit between the padding and the forehead.

Rawlings sells fit kits (extra pads) for the Mach and RX2 lines and the Mach Fit has a flex system that adjusts to the head; those are the answers for a kid between shells.

Typical size by age

Typical, not a rule; measure. Tee ball kids (4–6) usually land in the T-Ball shell (6 1/4–6 7/8). Seven- to nine-year-olds typically measure 6 1/2 to 7 (Youth or Small/Medium). Ten- to twelve-year-olds 6 7/8 to 7 1/4 (Junior, S/M or M/L). Thirteen and fourteen 7 to 7 1/2 (Senior or M/L). The full ranked helmets by age are on best youth batting helmets.

How we picked these

Researched, certification-checked and sized for the age

Every pick on this page earns its place the same way: the certification is checked against the governing bodies' rules and the maker's stated stamp, so the gear is legal for the division it is bought for; sizing comes from the makers' own age, height and hand charts; the published specs (drop, barrel, construction, closure, cleat type) are read from the maker's page; and the patterns in verified buyer reviews sharpen the “best for” line on each card. Every figure links to where it came from, with the date.

Scores are editorial judgments built from that documented research, applied with the same weights to every product in a category, so the ranking is comparable top to bottom. Commissions never set a score or decide a pick. The rubric and its weights are published.

Questions parents ask

Frequently asked

How do you measure a head for a batting helmet?
Soft tape around the head just above the ears and eyebrows, level, snug. Read the inches; divide by 3.14 for hat size.
What size batting helmet for a 7-year-old?
Most 7-year-olds measure 20 3/8–22 in, hat size 6 1/2–7: Rawlings' Youth CoolFlo shell or Easton's Z50 Small/Medium. Measure to be sure.
What size batting helmet for a 10-year-old?
Typically 21 1/2–22 3/4 in, hat size 6 7/8–7 1/4: Rawlings Junior (to 7 1/8) or Senior, Easton Z50 S/M or M/L depending on the exact number.
Is a batting helmet supposed to be tight?
Snug: it moves with the head, not on it, with no room for two fingers between the pad and the forehead. Padding compresses over a season, so start snug.
What is the difference between a junior and senior batting helmet?
Shell size. Rawlings' Junior is 6 3/8–7 1/8 and Senior 6 7/8–7 5/8 on the Mach and Velo; they overlap at 6 7/8–7 1/8, where you pick by the fit test.
