How To Measure Your Head Size

  1. To determine where you fall on SHOEI's sizing chart (as a starting point for proper helmet fit), pass a soft, flexible tape measure horizontally around your head at a height of approximately one inch (2.5cm) above your eyebrows (the largest measurement around your forehead).
  2. Select the helmet size that is closest to your head measurement from the sizing guidelines above. If your head measurement falls between two helmet sizes, first try on the smaller of the two helmets.


No helmet can protect the wearer against all unforeseeable high- and low-speed impacts. However, to help maximize head protection, the helmet must fit properly, and the retention system must be securely fastened under the chin. Failure to ride with a proper fitting helmet and securely fastened chinstrap is dangerous, as the helmet could come off during an accident, resulting in severe head trauma or death.

To determine the proper helmet fit and learn how to safely secure your chinstrap retention system, we recommend viewing SHOEI's "Helmet Fit" video at, or consult with an authorized SHOEI dealer today. Proper fit is important not only for comfort, but for safety, as well.
