Bell Helmet sizing chart and information
A properly fitted helmet is critical for your comfort and protection. A helmet that is too large or too small will not deliver the appropriate protection.

Measuring your head for helmet fitting
Using a seamstress tape, measure the circumference of your head approximately one inch above the eyebrows and at a point on the back of the head that yields the largest possible measurement. Take several measurements to insure accuracy. If you need assistance or advice on helmet sizing please call us at 800-866-4631 and we'll be happy to help.
