How to Measure for a Helmet
How to Properly Size Your Helmet

Measure the circumference of your head by placing the measuring tape roughly one inch above the eyebrow. Different helmet manufacturers have different sizing, so consult the size chart for the particular helmet that you are purchasing. Also consider how you will wear your hair in your helmet. If you are planning on wearing your hair up inside the helmet, allow room for this when choosing a size. When you receive the helmet, place it on your head without fastening the harness. If applicable, adjust the dial on the back of the helmet. Make sure the brim is resting no more than one inch above your eyebrows. Gently try to move the brim up and down. If your eyebrows move, your helmet fits correctly from front to back. Next, shake your head side to side, to the left and to the right. The helmet should remain in place. If either of these tests result in movement, you will want to drop down a size. If the helmet seems to be "perched" on top of your head, you will want to consider moving up a size.
