How Big Should a Helmet Be?

Published in Helmet Safety 2 mins read

A helmet should be snug but not uncomfortably tight, sitting level on your head with the front edge no more than one inch above your eyebrows to protect your forehead.

Here's a more detailed breakdown of how to determine the right helmet size:

Key Fit Considerations:

  • Snugness: The helmet should fit snugly all the way around your head. You shouldn't be able to easily rock it back and forth or side to side.

  • Level Positioning: The helmet should sit level on your head, not tilted back. Tilting it back exposes your forehead, defeating the purpose of the helmet.

  • Forehead Coverage: The front edge of the helmet should be about one inch or less above your eyebrows. This ensures proper forehead protection in case of a fall.

  • Adjustability: Most helmets come with adjustable straps and internal fitting systems. Use these to fine-tune the fit for optimal comfort and security.

How to Measure Your Head:

  1. Use a flexible measuring tape to measure the circumference of your head, just above your eyebrows.
  2. Compare your measurement to the helmet manufacturer's sizing chart. Sizing can vary between brands, so always check the specific chart for the helmet you're considering.

What to Look For When Trying On a Helmet:

  • No Pressure Points: The helmet shouldn't create any uncomfortable pressure points on your head.
  • Chin Strap: The chin strap should be snug but not too tight. You should be able to fit one or two fingers between the strap and your chin.
  • Movement Test: Once the helmet is adjusted, try shaking your head vigorously. The helmet should stay in place and not shift excessively.

Why Proper Fit Matters:

A properly fitting helmet is crucial for safety. A helmet that is too loose or too tight will not protect you effectively in the event of a crash.
