The Only Motorcycle Helmet Size Guide You Will Ever Needed
A perfectly fit motorcycle helmet can make all the differences between a fun experience and a tragic time. But choosing one that fits is no easy task. That's why we took it upon ourselves to show you how to measure your helmet size and some of the US brand helmet charts for your reference.
1. How to measure helmet size
What is a fitting helmet?
A fitting helmet should be one that is a little tight when you first try it on but not uncomfortably tight. Other than that:
- Cheek pads: You should be able to feel the cheek pads pressing against your cheeks, there should not be any gaps and no room to get your fingers in
- Forehead: Snug fitting with no room to get your fingers in
- Back of helmet: Should be snug up to the back of the skull
- Eyes: Your eyes should be in a central position in the visor area, if the helmet is nearer your eyebrows it is too big, if it is too high on the forehead it is too small.
- Twist and rotate: The helmet should have minimal rotation when twisted
- Back and forth: Finally try pushing the helmet back and forth, it should not come off or expose any part of the head. Again you are looking for minimal movement.
Measuring head's circumference
The deciding factor when it comes to choosing a helmet is the size of your head. Here's how you do it.
1. Use a tape measure and wrap it around the widest point on your head.
2. Make sure the measure is above the eyebrows and ears.
3. For most people, the tape would be right around the forehead and around the back of the head.
That is the circumference of your head and it will be used to decide the size of your helmet.
