Ever wonder how to measure your head before buying a motorcycle helmet? Well, the first thing you need is a tape measure.

In order to get the best fit, measure the largest circumference of your head or the distance from the center of your forehead above your eyebrows and ½”-inch above your ears around and around the back of your head. Make sure to double-check your measurement before moving on.

If your head measures 23½ inches for example, you’d fit into a size large Fuel helmet (size chart). A quick note: If your head size falls between two listed sizes, always choose the bigger helmet.

Now that you have your helmet size, you’re ready to go shopping. Here are a few tips:

Firmly grasp the chin straps and fabric that they are attached to and slide the helmet on your head from front to back. Keep in mind that a helmet should not go on easily.

The helmet should fit squarely on your head. It may feel a bit too tight until it is placed in the correct position. A new helmet should fit as tightly as you can possibly wear comfortably for maximum protection.

Next, fasten the chin straps. The helmet should press snugly on your cheeks.

There are three tests you can conduct to determine if you’ve found the perfect helmet. First, run your pinky finger between your head and the helmet liner by the forehead. There should be no gaps or open spaces.

Secondly, with your arms and shoulders braced in place, move your head from side to side. Your cheeks should feel the pressure, but the helmet should not move or shift.

Finally, with your arms and shoulders again braced in place, move your head up and down. Your cheeks should feel the pressure, but the helmet should not move or shift.

A helmet is the most important piece of protective gear you can wear while riding a motorcycle, according to the Motorcycle Safety Foundation.

“Helmet use,” they write, “is not a ‘cure-all’ for motorcyclist safety, but in a crash, a helmet can help protect your brain, your face, and your life.”
