Helmet Measurement, Sizing & Fit Guide

Proper Motorcycle Helmet Fitment

Helmet Sizing Chart

Find your helmet size by comparing your head measurement to our sizing chart. Sizes vary slightly between brands, so be sure to check the measurements for the specific helmet brand you are interested in.

Helmet Measuring Tips

  1. For an accurate head measurement, wrap the measuring tape horizontally around your head about 1" above your eyebrows.
  2. Your helmet should fit snugly. Keep the measuring tape comfortably tight in order to achieve the best results.
  3. For precise results, measure two or three times. If you get different measurements, take the largest one.
  4. If your head measurement falls between two different sizes on the helmet sizing chart, choose the smaller helmet size.

How to Choose the Right Helmet

Helmet Safety Ratings

Of the variety of helmet safety standards out there, the three most common you'll find are DOT, ECE 22.05 and Snell.

  • All helmets sold by J&P Cycles are DOT approved. A DOT rating means the helmet has met U.S. Department of Transportation standards for on-road use.
  • A ECE 22.05 rating means the helmet has met the United Nations Economic Commission for Europe's standards, which is required by over 50 countries. Check a helmet's description to see if it is ECE 22.05 approved.
  • A Snell rating means the helmet has met the private, not-for-profit Snell Memorial Foundation's standards. Check a helmet's description to see if it is Snell approved.
