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!!!
Answer
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

I use mainly my Giro Atmos but the new Lonos is the thing to buy, take a look:

EDIT: Actually McG - Bell and Giro are not made by the same people!
It is true however, that Bell bought Giro making it a wholly owned subsidiary.
