1. Fit cloth tape measure snugly around widest part of head approximately 1" above the eyebrow, just above the ears and at the point on the back of your head that will give you the largest measurement for your motorcycle helmet size (see illustration).

2. Find your head size in the correct chart above, then order the corresponding helmet size per the motorcycle helmet product sizing.

3. Safety dictates that if your head size falls between two of the motorcycle helmet head size ranges listed, order the smaller motorcyle helmet size as a motorcycle helmet must fit snugly.

*If you don't have a tape measure, you can use a piece of string. Wrap the string around your forehead about where you want the helmet liner to rest. Then use a ruler or yard stick to measure the string!
