Helmet sizing

Measure carefully around the head above the ears. Compare the measurement in centimetres with the size chart. Do not guess the size; the helmet must fit closely and securely.

How to measure your head for an Arai helmet.

1. Use a soft measuring tape.

2. Place the tape around the head about 2.5 cm above the eyebrows, just above the ears and around the widest part at the back of the head. Keep it close, but not tight.

3. Compare the measurement with the size chart.

If you are between sizes, choose the smaller size for a close fit. Contact us if you need help.
