A properly fitted ski racing helmet is essential for comfort, safety, and performance. A helmet that is too loose can shift during a run and reduce protection, while one that is too tight can create pressure points and discomfort. Measuring your head correctly and checking the fit will help ensure your helmet performs as designed.
Measure around your head approximately one inch above your eyebrows and around the widest part of the back of your head.
How to Measure for a Ski Racing Helmet
Wrap a flexible measuring tape around your head approximately one inch above your eyebrows, passing over the widest part of the back of your head. Record the measurement in either inches or centimeters and compare it to the helmet manufacturer's sizing chart.
If your measurement falls between two sizes, choose the larger size. Helmets should fit snugly without creating painful pressure points.

Helmet Fit Check
A properly fitted ski racing helmet should sit level on your head and remain secure during aggressive skiing. Perform these checks before using your helmet on the mountain.
- The helmet should sit square on your head and not tilt forward or backward.
- Cheek pads should make light contact without creating uncomfortable pressure.
- There should be no noticeable gaps around your temples, forehead, or the back of your head.
- Fasten the chin strap securely and gently shake your head side to side and up and down. The helmet should move with your head without shifting independently.
- With the chin strap fastened, try to roll the helmet forward off your head. If it rolls off easily, the helmet is too large.
- Wear the helmet for several minutes and check for pressure points or soreness. If discomfort develops, try a different size or another brand, as helmet shapes vary.
Common Helmet Fit Mistakes
- Choosing a helmet that is too large because it feels more comfortable initially.
- Tilting the helmet too far back, exposing the forehead.
- Leaving gaps between the helmet and the sides of the head.
- Failing to tighten or properly adjust the chin strap.
- Selecting a helmet based only on age instead of actual head measurements.
Race Place Fit Notes
- Always measure your head before purchasing a new helmet.
- Helmet fit varies between brands and even between different models from the same manufacturer.
- A snug fit improves comfort, stability, and protection while skiing.
- If you plan to wear a balaclava or thin liner, wear it while trying on your helmet.
- For racing, verify that your helmet complies with the certification requirements for your league or governing body.
