To know which size riding helmet you need, you can use the method below.
You can measure your riding helmet size in centimeters by measuring the circumference of your head. Using a measuring tape, measure the circumference of the head just above the eyebrows and over the thickest point of the back of the head.
The circumference in centimeters is the size of the riding helmet you need. For example: the circumference of the head is 55 cm, so you have a helmet size 55. Are you unsure between your 2 sizes? Then it is best to order multiple sizes or choose a helmet that is adjustable, so you can set the cap to the correct size yourself.
Points of attention when fitting a riding helmet:
If you are going to try on a riding helmet, always check whether the helmet shifts when you shake your head. Then loosen the chin strap and lean forward. Will the cap stay on? Then you have the right size and fit cap!
