Measure your head around the largest part. This is typically right above your ears.
Hold the tape measure slightly above one ear and bring the tape measure all the way around the circumference of your head to the other ear. Do this two or three times to make sure you have the exact measurement. Hold the measuring tape evenly.
Make a note of the measurement and try on helmets in that size. Typically, a head circumference of 22 inches would need a size 7 in a motorcycle helmet. But not all heads are shaped the same. Try on the helmet and wear it around the store for a few minutes to make sure it is the right helmet for your head.
Try on helmets from different brands. Some brands may fit the shape of your head better than others, according to the webbikeworld.com website.
Buckle the helmet while you are walking around and giving the helmet a trial run. Be sure the helmet doesn't bounce around and that the chin strap does not chafe your face and can be tightened to ensure a snug, but not too tight, fit.
