I think a 4 foot 7 inch 12 year old girl should weigh 70 to 80 pounds. I honestly think the answer above this is wrong, they should way 87lbs (pounds).

A normal 5 foot 2 inch girl should weigh between 100 and 135 lbs. If you have never weighed over 85 lbs during your 13 years, then you probably are not anorexic, you are just small for your age. If you are concerned, you should speak to your pediatrician about your weight.

you should weigh 130. there is a standard rule, that for the first 5 feet, a person should weigh 100 lbs, and then for every inch after that, add another 5 lbs. hope this helps!

Well, I am 12 years old and 4 foot 11 and I weigh 92 pounds, I'm pretty average in my town so if you weigh less or a little more than that you should be good

I am now 14 and I am 5'7 and I weigh 11stone 10lbs so a 13-year -old 5'7 girl should weigh pretty much the same but I am not a healthy weight girl so it depends

130 lbs, no less then 128. That's what my doctor says. If you are 75 lbs you are seriously under weight. That's how much a 3rd grader should weigh. And they're still in the 4ft zone.

A girl who weighs 5 foot 2 should weigh around 130 pounds. It altogether depends on the frame of the girl, and how slender she wants to be; 105 is about right for a petite girl.

well im 5'5 and i weigh 134 pounds and i have done many bmi caculators and my bmi is 22.3 which is perfect weight so you should weigh around 130- 140 :)
