How to choose your Bell helmet size

How do I know my Bell helmet size?

Step 1: Measure your head

Use a measuring tape to measure around your head one inch above your eyebrows. Or use a string to measure and then lay it out and measure the length of the string. Take several measurements to make sure you have the largest one.

Step 2: Choose your size

If your measurement is in between sizes, round up to the next largest one. If you use a balaclava or head sock, always measure and fit the helmet with it on. Use the chart to convert the measurement to your helmet size.

Step 3: Try on your Helmet

Fit the helmet model you would like to purchase. The helmet should have a snug-but-comfortable fit. When the helmet slides down on the head with no resistance, the helmet may be too large. When it doesn’t slide down over the head at all it is too small. When you feel some resistance at first, you might be reluctant to pull down, however, if it is just snug when pulling down, continue to pull the helmet on.

Most people will select a too-large helmet if left to make their own choice. A snug-fitting helmet is what you need. Helmets that are too large may not function as intended and in extreme cases may come off during an accident.

Step 4: Fit your motorcycle helmet

A helmet that feels snug:

  • should be worn low on the brow
  • Your eyes must be near the center of the eye opening
  • The helmet touches the top of the head with firm pressure all around – tight pressure points. 

Step 5: Buckle the Chin Strap

This strap should hold the helmet in place without discomfort, make sure the chin strap is snug against the throat.
