What should a 13 year old girls body mass index be?

Answer 1

They should weigh 100-130lbs if they are 5 feet-5 foot 8.
There is no specific weight for a 13-year-old girl (or a person of any age). Weight is related to height and body compositionrather than age. For more information about weight in relation to height, and to see charts showing the distribution of weights and heights of children at various stages, please see the page link, further down this page, listed under Related Questions. Alternatively, please feel free to ask the question again and include more detail.

I'm 13 year old girl and I weigh 150 I'm 5,5 am I over weight

Based on BMI calculation, a 5'5 person at 150 lbs has a BMI of 25.0, which is borderline overweight. Losing just a few pounds (5-10) will put you safely in the normal weight category. I hope this helps.
It depends on your height. Here below is a link you can go to to check your bmi. (body mass index.) It can tell you if you're normal, under, or overweight. http://pediatrics.about.com/cs/usefultools/l/bl_bmi_calc.htm

Answer 3

* I'm a 5' 2" 13-year-old girl and I weigh about 90 pounds, but people come in all sizes. I think I'm underweight.

* It depends on the size and height of each person. If you are concerned about your weight arrange an appointment with a doctor or school nurse. * There is no 'average' weight for a 13-year-old girl because weight is related to height and body composition, rather than age.
