Thor Youth Helmet Size Chart

How to Measure: Wrap a soft measuring tape around the widest part of the rider's head, just above the eyebrows and ears. Keep the tape level and comfortably snug, then repeat the measurement and use the larger result.

Fit Note: A youth helmet should fit securely around the crown and cheeks without painful pressure points or excessive movement. Do not intentionally choose a larger helmet to allow room for growth.

The interactive size finder uses head circumference in inches to recommend the appropriate youth helmet size.
