Just like any other helmet purchase, measuring the head circumference is required.

• the size small helmet fits kids with a head circumference of 48-56cm.
• The size medium fits those with a head circumference of 56-59cm. There is also a fit adjustment dial to make sure it's snug!

You can measure head circumference (just above their eyebrows) with a flexible measuring tape or use a piece of string and then measure it with a ruler.
