How much should I weigh?
I'm 15. 5'9 & I weigh 170
I'm male and the same height but I weigh 150 lbs. This does not mean you are overweight though, I have a friend who is the same size but has more mussle and he is built bigger, he weights 175 lbs.
Female: 120-160Male: 120- 180 However, it all depends. You could be a skinny girl, but have a heavier weight because of muscle. And if you are a guy, you could have a heavier build.
Not that much.
Bone structure plays a part, too.
