A school-age child who falls below the 5th percentile for height is considered to be of "short stature," a clinical term meaning he's shorter than 95 percent of kids his age and gender. On the other hand, a child who's in the 95th percentile is taller than all but a few of her peers.
Average height is anywhere between the 40th and 60th percentiles. Short stature is also a statistical term, generally referring to people who are shorter than 95 percent of those their age with the same sex.

Most doctors won't prescribe GH to kids who are not hormone deficient, but new research suggests it could add up to two inches to a healthy child's final height. The growth comes at a high price, however.
