What is the ideal weight for a 15-year-old girl who is 4'9''?
"Ideal" weight and the amount one really should weigh depends on
his or her body shape, physical activity, and overall health. For
example, a person who lifts weights a great deal will weigh more
than someone who does not because of the increased muscle mass.
Thus, that person's weight may be the same as someone who is
inactive. However, we use the term "ideal body weight" in medicine
to refer to a calculation that has to do with the height and sex of
a person. The ideal body weight for a girl who is 4'9" is 96 pounds
As an FYI, the calculation for women is 48.67 + (1.65 -
(inches-60)) Hope this helps! Dr. B.
