Giro Helmet Sizing
Giro Kids and Junior Helmet Size Guide
How to measure your child's head size
To find the circumference of your child's head, place a tape measure in the centre of their forehead, wrap it around above their ears and around the back of their head. If there's a slight difference between two different sizes, always go for the tighter size.
Giro cycling helmets are adjustable so will fit a range of head sizes. Once you know the circumference of your head, select an appropriate helmet size. For example, if your child's measurement is 47cm then a size Extra small - Scamp (45-49cm) or an Extra Small - Dime (47-52cm) will fit them.
