Helmet Size Measurement

The motorcycle helmet is the most effective and most important safety measure a motorcyclist can invest. There is no other single piece of motorcycle gear which provides more protection, or more return on investment, should the rider go down. This is why most recommend that the motorcycle helmet should not be bought with only the price or appearance in mind. A rider should buy the best fitting, most highly rated helmet he or she can afford.

1. Fit cloth tape measure snugly around widest part of head (as shown in picture) 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.

2. 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.

3. Not too tight: Once you have your new motorcycle helmet in hand, put the helmet on by grasping the chin strap in each hand and pulling it on over your ears until you feel the top portion of the motorcycle helmet touch. Check for the following red flags: A. The motorcycle helmet immediately feels too tight. B. Your head does not touch the top of the motorcycle helmet. C. You can't pull the helmet down over your ears. D. It's painful in any way. If any of these apply, you probably need the next size larger.

4. Not too loose: Once you have found a motorcycle helmet that feels comfortable and snug, you must make sure that it is not too loose. To do this, securely fasten the chin strap, grasp the helmet chin bar or sides firmly with one hand and try to move the helmet from side to side and up and down. If the motorcycle helmet slides on your skin and hair, it is too large. If your scalp and skin want to move with the helmet, the fit is about right.

5. Just Right: One final check. Reach back to the back of the motorcycle helmet and try to rotate the helmet as far down and forward as possible. Then as far backward as possible. If the motorcycle helmet feels as if it might slide off in either direction, the motorcycle helmet is either too big or the chin strap was not securely fastened.

Congratulations! If you passed these tests, you now have a properly fitting helmet that will maximize safety and minimize wind noise as well!
