Size Chart — Equestro Helmets

Equestro helmets are sized by head circumference in centimetres. Follow the guide below to find your perfect size.

How to Measure Your Head

Using a soft fabric tape measure, wrap it around the widest part of your head — approximately 2 cm above your eyebrows, level across your forehead, just above the tops of your ears, and around the fullest part at the back of your head. Keep the tape snug but not tight. Measure in centimetres and repeat 2-3 times to confirm.

Tip: If you don't have a soft tape measure, wrap a piece of string around your head following the same path, mark where it meets, and measure the string against a ruler.

Equestro Helmet Size Chart

Size XS S M L XL
Head Circumference 52–53 cm 54–55 cm 56–57 cm 58–59 cm 60–61 cm
Not all Equestro helmets are available in every size. Most models come in S, M, and L. Selected styles (Azael and Azael Stone ranges) also offer XS and XL for riders at either end of the size range. Check the size options on each product page.

How Equestro Sizes Compare to Other Brands

If you already own a riding helmet from another brand, use this comparison to find your Equestro equivalent:

Head (cm) Equestro Charles Owen KEP Italia GPA / Samshield
52–53 XS 6 3/8 – 6 1/2 52–53 (M shell) 6 1/2
54–55 S 6 5/8 – 6 3/4 54–55 (M shell) 6 5/8 – 6 3/4
56–57 M 6 7/8 – 7 56–57 (M shell) 6 7/8 – 7
58–59 L 7 1/8 – 7 1/4 58–59 (L shell) 7 1/8 – 7 1/4
60–61 XL 7 3/8 – 7 1/2 60–61 (L shell) 7 3/8 – 7 1/2
Note: Charles Owen and GPA use individual cm sizing rather than S/M/L ranges. The sizes above show the nearest equivalents. KEP Italia uses two shell sizes (M and L) with adjustable inner padding. Brand sizing can vary between models — always measure your head rather than relying solely on a size from another brand.

Between Two Sizes?

If your measurement falls right on the boundary between two sizes (e.g. exactly 55 cm, between S and M):

  • Size up — a slightly roomier helmet can be fine-tuned with the rear adjustment wheel. A helmet that's too small cannot be made larger.
  • All Equestro helmets feature a rear rowel adjustment system that lets you tighten the fit by up to ~1 cm, so sizing up gives you room to dial in the perfect fit.
  • The inner padding is removable and washable. Over time, padding compresses slightly, so a snug-but-comfortable fit on day one is ideal.

How Should It Fit?

  • The helmet should sit level on your head, with the front edge approximately 2–3 cm above your eyebrows.
  • It should feel snug but not tight — no pressure points, but no movement when you shake your head.
  • The chin strap should allow one finger's width between the strap and your chin when fastened.
  • If the helmet rocks forward/backward or side to side, try the next size down or adjust the rear wheel.
