How to Measure Your Head

Follow these simple steps to find your perfect helmet size:

  1. 1 Use a flexible measuring tape or a piece of string that you can measure later.
  2. 2 Wrap the tape around your head about 1 inch above your eyebrows and ears.
  3. 3 Make sure the tape is level and snug, but not too tight.
  4. 4 Note the measurement where the tape meets and compare it to the size chart above.
  5. 5 If you're between sizes, we recommend choosing the larger size for comfort.

Motorcycle Helmet FAQ

Everything you need to know about choosing and fitting your helmet

Measure around your head just above your eyebrows and ears using a flexible tape. Match your measurement to the brand's sizing chart for the best fit.
Your helmet should fit snugly without being painful. It shouldn't move when you shake your head, but it shouldn't press too hard on any spot.
Yes. The interior padding compresses slightly with use, so a new helmet should feel comfortably snug at first.
No. A helmet that's too loose won't protect you properly in an accident and can shift while riding.
Look for helmets labeled "glasses-friendly." They have extra space and channels in the padding to comfortably fit eyewear.
Helmets should typically be replaced every 5 years or after any impact, even if there's no visible damage.
No. Each manufacturer has unique size and shape standards. Always refer to the brand's sizing guide before buying.
These are different safety standards. DOT is the U.S. minimum requirement, ECE is used internationally, and SNELL helmets undergo additional independent testing.
