If you’re not sure what size children’s helmet your little one needs, never fear – measuring for a helmet is very easy and only takes a few minutes. Use a soft tape measure (like a dressmaker measuring tape) and measure the circumference of your child’s head (do this around the eyebrows as this is typically the thickest part of their head). All our helmets come in a centimetre range so you will be sure to find a kids helmet that will suit your child’s size.
