Whats the avaergae weight for a 5 foot 2 ,15 year girl??

Can estimate by...: An estimate of an average woman's weight can be done by starting with 100 pounds for the first 5 feet of height, plus 5 pounds for each additional inch. Thus, 100 + 10 = 110 pounds in this case. However, women and girls come in a whole range of body types. A 5'2" teen girl can be slim and 90 pounds, or larger build and be 120 pounds.
