It’s important to know that each brand skateboard helmet size varies from one another; therefore, it would be best to measure your head and then refer to the sizing chart to get one fits you best. To measure your head size, wrap a tape measure horizontally around your forehead. Select the helmet that is the closest fit to that size. A helmet should fit snug on your head. If it moves while wearing, it is too large. If it is painful to wear, it is too small. If your measurements fall right in between 2 sizes, it would be best to select the larger size. Your helmet should fit snug without feeling overly tight.
