As well please use SIZING CHART here.
In order for a helmet to protect properly and be the most comfortable, it must be sized to your head correctly.
The best way to check sizing is to put the helmet on and see that the helmet feels snug equally all around your head. The helmet should not feel too tight or too loose at any particular point around your head.
If you can’t put it on, at all, then that’s obviously too tight. If you can get it on, but it hurts where it presses against your head, that’s also too tight. If it’s snug all around, too snug to chew gum, that’s about right. Don’t forget about that 15 percent to 20 percent break-in that will occur.
