Find Your Perfect Fit
Choosing the right size is one of the most important parts of buying a motorcycle helmet. Use the guide below to measure your head and compare your measurement with the appropriate Hedon size chart.
How to Measure Your Head
Measure around the widest part of your head, approximately 2cm above your eyebrows, passing just above your ears and around the back of your head.
Use a soft tape measure and record the measurement in centimetres.
If you're between sizes or unsure which helmet is right for you, we're always happy to help.
Understanding Head Shape
Your head shape can affect how a helmet fits, even when the circumference measurement is correct.
Hedon helmet models suit slightly different head shapes, so use the illustration below alongside the individual size charts.
