What is the aerage weight for a 12 year old girl?

I'm a 5'5" 12 year old girl and am 105 pounds. I don't know if that's average, but I think it's somewhere around there. Depends on how much you eat, what you eat, and how tall you are.

I'm also a 5'5" 12-year-old girl and I'm 120 pounds. 105 pounds is underweight, but I think it's normal if you're prepubescent. I've practically finished puberty, so yeah.

i'm a 12 yr. old that's 5'5" and i weigh 133 pounds. if you think your over weight, your not.
