This is how to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible measuring tape.
It is important that the measuring tape runs at the widest part of the head – only then will you get an accurate result.
Place the measuring tape about 1–2 cm above your eyebrows at the front and run it along the sides above your ears.
At the back, the measuring tape should run over the largest point at the back of the head (not too low in the neck). The tape can run slightly diagonally – what matters is that it fits snugly around the largest circumference points of the head.
Make sure the measuring tape fits snugly but does not pinch. It’s best to measure 2–3 times to achieve the most accurate result. You can then compare the measured value in centimeters (cm) with our size chart.
Tips for an accurate result
- Lay hair flat (e.g., do not measure with a voluminous hairstyle)
- Run the measuring tape horizontally or along the largest circumference
- Do not measure too loosely
- For values between two sizes:
→ usually choose the larger size (depending on helmet model/fit)
Important for fit
The right helmet should fit snugly without causing uncomfortable pressure points.
A new helmet may feel a bit tighter at first, as the inner padding will adjust slightly over time.
