You can't tell how tall someone is going to grow up to be when you cast them at 11. But being on the short side is usually a plus for child actors. It allows them to play younger than their age for longer. Tom Felton starts getting quite tall and mature looking, like in Goblet of Fire I think he's 17-18 playing 14 and he looks his real age.
