How to measure your head


Use a soft tape measure to measure the circumference (around your head) an inch (2.54cm) above your eyebrows. Keep the tape level from back to front.


If you don’t have a measuring tape, use a piece of string, then lay the piece of string out on a table and measure the length with a ruler.


If the helmet is a gift and you cannot measure the head, measure the inside of a current helmet they wear.


Use the chart to convert to hat size.
