Kask helmet size chart

The 4 Kask helmets we track cover heads from 50 to 63 cm (19.7 to 24.8 in). A Kask L is not the same as an L from another brand — here are the real numbers.

Which Kask size am I?

Measure your head first (tape or string around the widest part, 1-2 cm above the eyebrows), then read it off the table above — Kask sizing is not the same as the next brand's. Across the range, Kask covers 50 to 63 cm (19.7 to 24.8 in). If your measurement falls outside that, no Kask helmet we track will fit you.

Safety ratings

None of these Kask models has been rated by the Virginia Tech Helmet Lab yet. That is not a safety verdict: it just means the lab has not bought and tested them. Every helmet here still meets its market's legal standard (EN 1078 in Europe, CPSC in the US).
