Match the body and scale to the player rather than the age: fractional sizes exist for a reason, and a smaller-bodied full-size guitar — like a small dreadnought with a cutaway — often fits a growing teenager better than a fractional one.
The two dimensions that matter
Scale length, which decides how far apart the frets are, and body depth, which decides whether the arm can comfortably reach over.
Why depth is underrated
A child can often reach the frets of a full-size guitar and still cannot hold the body comfortably. Slim-line and small-dreadnought models solve exactly that, and Rocktile publishes the reduced depth for its WSD-5C.
The test that settles it
Sitting down, the strumming arm should rest over the body without the shoulder lifting. If the shoulder lifts, the body is too deep.
The questions players ask
Nylon or steel for a child?
Nylon is much kinder on fingertips, but a classical neck is wider, which small hands find harder. Body size usually matters more than string material.
Will they grow out of it?
Fractional guitars, yes, within a couple of years. That is the argument for a smaller full-size instrument where the child is close to being able to hold one.
