Arai Helmets Sizing Chart

Arai Helmets Sizing

The recommended way to measure your helmet fitting is to use a cloth (soft) tape measure around your head, just above your eyebrows and ears. Pull the tape measure comfortable, but tight then read the length. Repeat this for good measure to ensure you have the right measurement. Please note: Sizing information is provided by the manufacturer and does not guarantee a perfect fit.
