I don't know much about the average height of Olympic gymnasts, but I happen to have found the listed heights of 80% of the female gymnasts at the 2004 games; they averaged 60 inches tall. That is pretty small: roughly the 5th percentile for growth.I thought I had read somewhere that the average height of an Olympic gymnast was about 4'10". I don't worry about the growth thing. My pediatrician said my dd will most likely be about 5'8". . . .
