Baseball Helmet Size Chart | Measure Once, Fit Right

There’s no universal baseball helmet size chart. A youth large from Rawlings may fit differently than an EvoShield medium, because each manufacturer builds helmets around its own headforms. The reliable route to a correct fit starts with one measurement and ends with the brand’s own chart for the exact model you want. The generic US ranges below help you narrow the field, but they’re a starting point, not a verdict.

How To Measure For A Baseball Helmet

Wrap a flexible tape measure around the head, positioned just above the ears and across the middle of the forehead. That horizontal line is the widest part of the skull, and it’s the circumference every manufacturer bases its sizing on. Keep the tape snug but not tight, and record the measurement in inches.

Two things to avoid: measuring high on the crown gives a too-large number, and measuring across the forehead alone misses the width that actually determines fit. Write down the number, then check it against the chart for the specific helmet model.

When you try the helmet on, the fit check is simple. The shell should sit about 1 inch above the eyebrows, stay firmly in place when you shake your head, and the ear holes should line up with your ear openings.

Generic US Baseball Helmet Size Ranges

Retailers like DICK’s Sporting Goods publish a general guide, but they’re the first to note it’s only a starting point and manufacturer charts should be checked first. These ranges show where most players land:

Notice the overlap between categories. A 22-inch head sits at the top of youth and the bottom of adult, which is exactly why the generic chart can’t be the final word. The brand chart resolves that ambiguity for the specific model.

Brand-Specific Sizing Charts

Rawlings keeps a helmet sizing chart on its site that lists both general ranges and model-specific adjustments. Their basics: the Junior range covers 6 3/8″–7 1/8″ hat sizes, and the Senior range spans 6 7/8″–7 5/8″. Rawlings explicitly says to measure the head circumference just above the ears and match it to the chart for the specific helmet, because adjustable ranges differ by model.

EvoShield’s XVT 2.0 batting helmet chart works the same way, with four overlapping ranges to account for the adjustable fit system:

The overlap between EvoShield’s S–M and M–L ranges isn’t an error. It gives you room to choose based on head shape and how the adjustable liner sits, so try both sizes in the overlapping zone if you can.

Safety Standards Behind Helmet Sizing

Batter helmets sold today must meet NOCSAE’s ND022-21m24 standard. The organization that sets the rules also notes a quirk in testing: helmets of a given model smaller than 6 5/8 may not fit the smallest NOCSAE test headform, and in that case, testing of that size is waived if the other sizes in the model have passed. That’s worth knowing if you’re buying for a young player with a smaller head — the tiny sizes get less direct verification.

Two more notes from NOCSAE: recertified helmets fall under standard ND026-24, effective March 3, 2025, and catchers’ helmets are governed by their own separate standards. Don’t assume a batter helmet sizing chart applies to a catcher’s mask.

FAQs

Should I buy a baseball helmet a size up for a kid to grow into?

Manufacturers recommend against it. A helmet that’s loose won’t stay properly positioned during impact, which defeats the protection it’s designed to provide. Buy the correct current size and replace it when the player outgrows it; that’s the safe approach.

What if my head measurement falls between two helmet sizes?

Try both sizes and pick based on how the liner fits your head shape. In the overlapping zone, one will usually feel noticeably more secure. The helmet should sit about an inch above the eyebrows and stay firmly in place when you move your head.

How do I know if my helmet meets current safety standards?

Check for the NOCSAE seal and the standard number marked on the inside of the shell. New batter helmets should carry ND022-21m24, and recertified helmets should meet ND026-24, which took effect March 3, 2025.
