110lbs
the average height of a 13 year old girl according to wiki answers is annything between 5ft 0in and 5ft 4in
110-130 im 5ft 4in and 15 years old and i weigh 125lbs but im a highly competitive dancer so im pretty much all muscle with a small frame but im on the higher end because muscle weighs more then fat.
All I know is if you are 5ft 7" and 19 years old your ideal body weight for an average build is 135lbs so im sure 5ft 8" is just a little more mabey 140ish ?
