How to Measure for a Helmet

Choosing a helmet size online can be intimidating but between this blog and our return policy, it doesn’t have to be.

How to measure for a helmet: 

Using a flexible tape measure (in cm), begin a finger’s width above the eyebrows, taking the measuring tape through the temples, brushing the tops of the ears and going around the back of the head in the fullest part. Riders, be sure to wear your hair how you’ll wear it with the helmet. If you normally ride with your hair in your helmet but don’t include your ponytail in the measurement, your helmet most likely won’t fit your ponytail in it.

PRO TIP: if you don’t have a flexible tape measure, use a piece of string and then measure it on a yardstick or measuring tape.

Now that you have the measurement, you’re halfway there (don’t worry, we’ll try to make the second half just as easy)! We typically recommend rounding up to the nearest centimeter and then going up a size from there. Our helmets are sized by the circumference of their shell, so if you measure exactly at 55 cm and get a 55 cm helmet, it won’t fit as the shell is 55 cm and doesn’t account for the helmet liner.  To further illustrate this example, if the rider measures at 58.6 cm, then round up to 59 and up one size from there to a size 60 cm helmet. 

Now that you’ve found your helmet size, shop our selection of riding helmets and be sure to visit this blog again once your helmet arrives to check the fit.

How to tell if your EQ3 fits:

Your helmet is here! Thanks for shopping with us! To check the fit of your helmet, place the helmet on without fastening the harness. You should feel an even and snug fit around the circumference of your head. Next, shake your head side to side or ear-to-shoulder, there should be no movement. Lastly, nod or move your head front to back—there should be no motion. 

If there’s movement from side to side but not front to back, remove the liner that came with the helmet and insert the additional liner found in the bag attached to the hang tags; this is plusher on the sides than in the front and back. Try shaking your head side to side again. 

If there’s movement front to back, then we need to go down a size; it’s too big! If the harness of the helmet is hitting the ear lobe or the entire helmet is resting too high on the rider's head, then we should try going up a size. We always recommend wearing the helmet around your house for 15-20 minutes. During this time, you typically will be able to tell if the helmet is a good fit or not. Since the liner is designed to conform to the shape of the rider's head, it should be snug at first. If the helmet is too comfortable or is giving the rider a headache or pinching in certain areas, try the oval liner or keep scrolling for info on how to return your helmet.

How to tell if your Lynx fits:

Woohoo! It’s here, thanks for choosing Trauma Void, we’re excited to have you on our team! To check the fit of your Lynx helmet, place the helmet on without fastening the harness and adjust the dial to a firm, even, fit. Shake your head side to side or ear-to-shoulder, there should be no movement. Lastly, nod or move your head front to back; again, there should be no motion. If the dial is as tight as it can be and there is motion, then we should try going down a size.  If the dial is as large as it gets and the helmet is perched or not sitting down on the head, then try going up a size. Riders should wear their helmet around the house for 15-20 minutes to make sure that this is the best fit for them, (especially if the dial is at either the smallest or largest it can go).  As the liner conforms to the shape of the head, riders will get a pretty good feel of how the helmet will sit.  

What to do if your helmet doesn’t fit:

Earlier we mentioned the importance of wearing your helmet around the house for a little. One of the largest factors in our return policy is that it has the hang tags attached and hasn't been ridden in.  If you aren’t confident in the fit of your helmet, make sure to exchange the helmet before riding in it to be able to take advantage of our return policy. As a company, we understand the importance of a well-fitting helmet, so we’ve made a return policy to support that.
