Determining your head shape will help you choose a size that will fit comfortably. There are three primary helmet shapes:

Long Oval - this shape is much longer front to back than it is wide from side to side.

Intermediate Oval - this shape is slightly longer front to back than it is wide from side to side. It is the most common shape, especially among American helmet brands. This is also the most common head shape in North America.

Round Oval - this shape is almost equal front to back as it is side to side.

Understanding your head shape helps you ensure you choose a helmet that will provide you enough space and flexibility. Quin Helmets come in two shapes - intermediate oval and round oval. See the chart at the end of this page.


Quin Helmets are designed for a safe, snug fit and run small in comparison with many other brands. Every Quin Helmet also comes with additional padding that helps you customize your fit. If you are between sizes, choose the size larger rather than the size smaller. The additional padding will help provide a good fit, while ensuring the helmet is not too small for you. The Quin team will be more than happy to assist you with sizing and can provide you a detailed size recommendation and fit comparison. For expert sizing support, please reach out at
