Helmet size by age
A typical 2 year old's head is 48 cm around, a 5 year old's 51 cm, an 8 year old's 52.5 cm and a 12 year old's 54.5 cm. Measure 1 in above the eyebrows and buy by the helmet's own fit range.
A helmet that is one size off does not protect the way it should, and kids' heads change quickly. Start from the typical head circumference at your child's age below, then measure the actual head and buy by the helmet's own stated fit range, which matters more than the age on the box.
