How to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible tape measure.
It is important that the tape measure runs around the widest part of the head – only then will you get a correct result.
Place the tape measure at the front, about 1–2 cm above the eyebrows, and run it along the sides above the ears. At the back, the tape must run over the largest part of the back of the head.
Make sure the tape sits snugly but does not dig in. Measure 2–3 times for the most accurate result, then compare the value in centimetres (cm) with our size chart.
Tips for an accurate result
- Keep hair flat
- Keep the tape horizontal, along the largest circumference
- Do not measure too loosely
- For values between two sizes: usually choose the larger size
Important note on fit
The right helmet should fit firmly without uncomfortable pressure points. A new helmet may feel a little tighter at first, as the inner lining adapts slightly over time.
