Wrap the flexible measuring tape around your head. You should position it just above your eyebrows.
Make sure the measuring tape lays flat against your head but doesn't pinch. It should be level all the way around.
◦Doing this on your own is a challenge. Ask a friend or family member for help, or use a mirror to help you level the tape.
◦If you're measuring your head circumference on your own, cross the ends of the tape on the front of your head to make reading the measurement easier.
Read the measurement off the tape. Take several measurements. The largest measurement you take is the measurement to go by.
Write down this measurement so that you will remember it when it comes to choosing a helmet.
