Home > Helmets > Arai Helmets > Arai Helmet Size Chart BEFORE ORDERING: Measurement Measuring the head is a starting point for the entire sizing procedure. Due to varying shapes, heads that are apparently the same size when measured by a tape may not necessarily fit the same size helmet.The circumference of the head should be measured at a point approximately one inch above the eyebrows in front and at a point in the back of the head that results in the largest possible measurement. Take several measurements to make sure you have the largest one. This is the size to compare on our charts. NOTE: If you have facial hair (beard) or an unusually thick head of hair, you may want to consider ordering 1 size up from what is shown on the sizing charts...especially if you are near the top of your size range.
