How to measure
Use a soft tape measure starting at your forehead about one inch above your eyebrows, wrapping across the largest portion of the back of your head. Match that measurement to the chart. No soft tape? Wrap a string the same way, then measure it flat with a ruler.

One official FLY chart covers all moto/MX and street helmets (the brand publishes separate MOTO and STREET chart images, but they are identical). Snow and bicycle helmets use their own charts. cm ranges are official; inch ranges converted from cm (FLY publishes a ruler-style chart, not an inch table).
