Bike Helmet Size
Bicycle helmet shell dimensions?
I am designing a bike helmet shell, can anyone tell me what the dimensions of just the shell are of a child to adolescent sized helmet? Thank you!!!
Smallest sized helmet generally available is 48 cm (18.9 ")
There were smaller helmets around but most manufacturers steer away from these. The skull bones of a child less than this size may not have sutured together.
An adolescent can have a fully grown head
Larger sizes of 63 cm (24.8") are common. Some people need an even larger helmet.
Rough guide width 0.8 times length. Depth 0.4 times length
