Go-Kart Helmet Size Chart: The Ultimate Guide

When it comes to buying a go-kart racing helmet, it’s imperative that you get the right size. On the one hand, if your karting helmet is too loose, it can fall off during a race and it can also potentially dislodge during impact. On the other hand, if your go-kart helmet is too tight, you’re going to feel uncomfortable, which can lead you to become distracted from your race.

It’s therefore extremely important to ensure that your go-kart helmet has the perfect fit for your head. Getting the perfect size for your go-kart racing helmet isn’t always easy. The important thing that you need to do is to ensure that you read the manufacturer’s measurements carefully and match this with your own head dimensions.

I’ve created an extensive list of helmet size charts that will give you an idea of each manufacturer’s dimensions. It features the go-kart helmet size chart list for each manufacturer. Please use these helmet size charts only for reference and check exact dimensions on the manufacturer’s website. This is a live list, and I will keep adding more over time.
