To find your approximate size use a soft tape measure. Start at your forehead approximately one inch above your eyebrows and across the largest portion of the back of your head. Cross reference this measurement on the helmet size chart to determine the approximate size.
If you do not have a soft measuring tape, use a string or phone charging cord in the same way. Then lay it down and measure with a ruler.
