Helmet Sizing Guide

If you're looking for a new helmet, follow these steps to make sure you get the correct size...

STEP 1: MEASURE YOUR HEAD

  • Wrap a soft tape measure around your head, just above the eyebrows, keeping the tape level from front to back
  • If you don't have a soft tape measure, use a piece of string and then lay the string out on a table. Use a ruler to measure the total length
  • If the helmet is a gift, and you don't want to (or can't) measure the head, then measure the inside of his/her current helmet or a baseball hat they wear frequently


STEP 2: CONVERT TO CENTIMETERS

Our helmet sizing tables are in centimeters. Use the table below to convert from either inches or hat size.

STEP 3: CHECK THE HELMET'S SIZE CHART

Helmet sizing is unique for each helmet model, even different helmets from the same manufacturer. It's important to confirm correct sizing for the exact helmet you're going to buy.

On each helmet's product page, there is a Tab called "Sizes". Using your head size from above, figure out the correct helmet size for you and then add the helmet to your shopping cart.
