Charles Owen helmets size chart

A properly fitted helmet is essential to riding safely. Our quick fitting tips and size conversion chart will help you get the correct sizing. We’ll also share a video to show what happens during a professional hat fitting, and lastly touch on advice for buying a kids helmet.

Charles Owen’s helmet range caters for every head shape. If one helmet model doesn’t feel quite right, try a Round Fit version or another model.

How to size your head for a riding helmet

Using a soft fabric measuring tape, wrap it around the widest part of your head (over your hair).

It should follow a line about ^3/4 inch above your eyebrows, just above the ear line and around the bump at the back of your head.

Take the measurement in centimetres (cm) and repeat a couple of times for the most accurate sizing.

Unlike most other helmet brands which rely on adjustable or broad size ranges (small/medium/large), Charles Owen sizing is very specific because that ensures the safest and most comfortable fit.
