Your Guide to ski helmet sizing

Why Ski Helmet Sizing is Vital

Proper ski helmet sizing isn’t just about comfort. A well-fitted helmet can make the difference between a minor inconvenience and a serious injury. When you’re zooming down slopes at high speeds, even a small object or a sudden fall can lead to significant impacts. In such situations, a helmet that’s too large might slide off, while one that’s too small could restrict blood flow or fail to provide full coverage. Hence, proper sizing is not just a preference—it’s a necessity.

At Zerokay, we understand that comfort, safety, and style are essential for an unparalleled skiing experience. That’s why we have crafted this how to measure helmet size guide to ensure you find the perfect fit for your helmet and goggles, optimizing your ski helmet sizing.

How to Measure Your Head for a Zerokay Helmet?

  1. Get a Flexible Tape Measure: A cloth or flexible plastic tape measure is ideal for this ski helmet sizing task. If you don’t have one, you can use a string or a cord, which you can then measure against a flat ruler.
  1. Measure Your Head: Position the tape measure just above your ears and about 1 inch (2.5 cm) above your eyebrows. This is usually the widest part of the head. Wrap the tape measure evenly around your head, ensuring it covers the largest portion of the back of your head. Remember not to pull the tape too tight; it should sit comfortably.
  1. Check the Measurement: with your head measured in accordance with ski helmet sizing, pinpoint the spot where the tape measure comes full circle, look at the number where the tape measure meets the end. This is your head circumference. If you used a string, measure its length with a ruler.
  1. Repeat for Accuracy: for the best ski helmet sizing, it’s crucial to repeat the measurement process a couple of times.
  2. Considering ski helmet sizing: simply compare your head circumference to our size chart. If your measurement is between two sizes, opt for the larger size for maximum comfort.
