Steps to Proper Helmet Fit

Bike Safety • Bike Helmet Check • ABC Quick Check

1) Position:

The helmet should sit level on your head and low on your forehead—one or two finger-widths above your eyebrow.

2) Side straps:

Adjust the slider on both straps to form a “V” shape under, and slightly in front of, the ears. Lock the slider if possible.

3) Chin strap:

The buckle should be centered under your chin. On most helmets, the straps can be pulled from the back of the helmet to lengthen or shorten the chin straps. Now buckle your chin strap. Tighten the strap until it is snug.

Final fit:

  1. Does your helmet fit right? Open your mouth wide…big yawn! The helmet should pull down on the head. If not, refer back to step 3 and tighten the chin strap.
  2. Does your helmet rock back more than two fingers above the eyebrows? If so, unbuckle, shorten the front strap by moving the slider forward.
  3. Buckle, retighten the chin strap, and test again.
  4. Does your helmet rock forward into your eyes? If so, unbuckle, tighten the back strap by moving the slider back toward the ear. Buckle, retighten the chin strap, and test again.
  5. Roll the rubber band down to the buckle. All four straps must go through the rubber band and be close to the buckle to prevent the buckle from slipping.

Other tips:

  • The helmet should fit you NOW: Buy a helmet that fits your head now, not a helmet to “grow into.”
  • When to replace a helmet: Replace any helmet that has been involved in a crash or is damaged.
  • Remember: A helmet can only protect you if you wear it each time you ride!
