Ski Helmet Measuring Guide
Before you pick up your next ski helmet or ski helmets for the kids, you need to make sure it’ll fit! You need to make a quick measurement and in this Ski Helmet Measuring and Sizing Guide we’ll show you a couple of tests which you can do to make sure it will fit perfectly.
How to Measure Your Head

When you’re taking your measurement, use a soft measuring tape if you have one to hand and make sure you measure from just above your eyebrows round just above your ears and make sure you measure round the back of the largest part of your head.
Ski Helmet Size Guide
Then you need to take your head measurement and see which size you need based on the manufacturer’s sizings. We’ve included a table below which should give you a rough idea for your helmet and kids helmets but do make sure you check the manufacturer’s guide as these can differ.
Adult Helmet Size | Head Size (In) | Head Size (Cm) |
---|---|---|
Small | 20.5" - 21.75" | 52cm - 55.5cm |
Medium | 21.75" - 23" | 55.5cm - 59cm |
Large | 23" - 24.5" | 59cm - 62.5cm |
XL | 24.5" | 62.5cm+ |
Childrens Helmet Size | Head Size (In) | Head Size (Cm) |
---|---|---|
Small | 19" - 20.5" | 48.5cm - 52cm |
Medium | 20.5" - 21.75" | 52cm - 55.5cm |
Large | 21.65" - 23" | 55.5cm - 59cm |
Do take a little bit longer when fitting your children’s helmet as you’ll need to make sure you get a nice snug fit but also make sure that it’s comfortable for them for a full days skiing. There are a few different adjustment methods on helmets these days including adjustment dials, in-form fit systems, additional foam pads which you’ll be able to consult the specific manufacturer’s guidance on to use. We’ve included a few tests below however which you can do to make sure you’ve got the right fit.
- Roll test: Once you’ve got your ski helmet on, dialed in your adjustable fit, get your chin strap done up and fastened and then do a ‘roll test’. Grab your ski helmet with both hands and try to roll it over your head in every direction. You may get some slight movement in your helmet but you should then feel your helmet kick in and grab your head so that you cannot move your ski helmet without your head moving too.
- Run test: More one to check that your chilren’s helmet is fitting nice and snug – get them to do what they do best, run around! This will produce similar movements to when they’re skiing and you should be able to tell if its a good fit.
Fitting Goggles and Sunglasses
You should also bear in mind your ski goggles when you’re fitting your ski helmet. Some good brands of ski helmet sell ski helmet and goggle combos which you know will fit perfectly together as they’re designed to leave a minimal gap between your ski helmet and your goggles (no chilly foreheads).
Otherwise, if you already have goggles then make sure you take a brief glance at their size and make sure they’ll fit neatly with your ski helmet.
If you prefer sunglasses (or wear glasses) then do look at the helmet specifications as some ski helmets (and goggles for that matter) are designed specifically for you to be able to use your sunglasses/glasses comfortably.
