Another consideration is stock drop, the distance from the bore line to the comb of the stock. A shorter person has a shorter neck than a tall person. A full size stock has much more drop than a shorter person needs thus their jaw is against the stock and not their cheek. Too much drop is not conducive to comfortable accurate shooting because your head isn't stable and you get slapped in the jaw when you pull the trigger. Stock drop also effects sight acquisition, with too much drop your head jiggles and you'll nod up and down.
Teach them right the first time with a gun that fits and they will enjoy shooting more, be more accurate, receive less recoil, will be less likely to develop a flinch (hard to correct later) and be more confident and successful.
If you can't get a youth stock to fit that rifle, get a rifle that fits the kid.
