How to Fit a Bike Helmet Fit

Ever wonder what the most important criteria is for finding the right fit for a bike helmet? This quick overview will help ensure you find a helmet that fits so comfortably you’ll actually want to wear it.

Choose a helmet of your size
Helmets typically come in small, medium, and large. The helmet sizes can also correspond to a measurement range (inches and/or centimetres) of different head sizes so you can be sure you’re buying the right size. If you’re not sure about your head size you can wrap a measuring tape around your head about a half inch above your eyebrows. Don’t wrap the tape too tightly as you want the helmet to fit comfortably.

Get the right fit
Now that you have picked out the right size you can get the perfect fit by making minor adjustments to the helmet itself. Almost all helmets have a sizing dial on the back of the helmets internal sizing ring. Put the helmet on your head and tighten dial until the helmet no longer wobbles or slips.

Position the helmet correctly
The helmet should sit level on your head (not tilted back) with the front edge one inch (two fingers) or less above your eyebrows so that your forehead is protected.

Buckle and tighten the chinstrap
The straps should join right under your ear to form a “V”. Adjust the straps around both ears until you have a comfortable fit. There should be just enough room to fit your finger between the strap and your chin. Another test is to open your mouth wide with the straps done up. You should feel the helmet press against the top of your head.

Make sure it’s one you’ll wear
Even if a helmet feels comfortable it’s got to be a helmet you like the looks of. You probably won’t want to wear it otherwise. Finding one that matches your style can seem like a daunting task when they’re are so many different styles, infinite colour options, and an endless number of unique features that differ from one helmet to the next.

    Look for a helmet that matches the shape of your head as well as the size of your head. Abus helmets, in particular, are extremely oval in shape which fits a lot of people poorly. Most other brands are more rounded.

      Good to know. I have a long head and can never get a good helmet fit. Abus might be just the ticket.
