Do you mean how does the nail get wider in proportion to the rest of the finger? The nail bed is alive, it contains cells that produce keratin for the nail, just like hair growth from a follicle. The nail bed grows with the finger just like any other body part, and so as it gets larger, the nail it produces does too.
