Size Chart - Helmets
Measuring your head is simple. Due to varying shapes, heads that are apparently the same size when measured by a tape may not necessarily fit the same size helmet. Other helmet manufacturer's helmet sizes may vary slightly. If you are not sure of your head size, helmet size please measure and contact us if you have questionsHelmet Size Charts below for Arai, Fox and Shoei.

The circumference of the head - should be measured like this:

  1. Place the end of a plastic or cloth tape measure approximately 1" above your eyebrows in front, pull it around the back of the largest part of your head in the back
  2. Pull the end of the tape back to the front and you should see your measurement.
  3. Make sure you have placed the portion of the tape in the back at the largest or widest point at the back of your head to get the largest possible measurement.
  4. Measure 2 or 3 times to make sure you have the largest one - then use measurement to compare with the chart below.  
  5. Head circumference shown below, use cm or inches to determine your head circumference, then match it to the helmet size.  Most adults measure 21 1/2" and up and a lot of adult men's heads measure 23" and up.
