Proper Fitting for a Riding Helmet



Any experienced rider will tell you that riding accidents and falls are not a matter of if, but when. A proper fitting helmet is one of the most important pieces of riding gear you can own. The protection that a helmet provides can literally save your life, but in order to do so effectively, it’s vital that the helmet is fitted and worn properly. This guide will help you select the right helmet and size and ensure that you are wearing it correctly in case of an incident.

Don’t guess your size

The best way to determine the right helmet size is to use a tailor’s measuring tape and measure around your head above your ears and just above your eyebrows. Use the chart below to select the right size helmet.

A correctly fitting helmet

For maximum protection, your helmet should fit firmly but comfortably. If the helmet is too loose, it will move around on your head while riding. If it’s too tight, it will be uncomfortable. When you try on a helmet for fitting, wear your hair the way it will be worn when you’re riding. Wear the helmet level on your head, with the front edge riding just above your eyebrows. The visor’s brim should be about an inch (two finger widths) from your eyebrow. Once in place, the helmet should remain stable and not roll forward or backward on your head and there should be no noticeable pressure points. Many helmets come with removable padded inserts that can help perfect the fit of the helmet. If you can deeply bow your head with the retention system unbuckled and the helmet does not feel that its about to fall off, you have a good fit. Never purchase an oversized helmet to “grow into”. It is just not worth the risk of serious injury.

The retention system

Now that you have the right helmet size, make sure you read the instructions on proper use of the helmet’s retention system. The retention strap should fit snugly under your jaw without causing discomfort. Properly fitted, you should only be able to fit two fingers between the strap and your chin. With proper fitting helmet with a properly adjusted retention system the helmet should not move significantly if you try to roll it off of your head.
