Average wheight for a 13-14 year old?!

Completely depends on your height. I'm 16 and 5'9" (guy). I weigh 151, but have a muscular build. I know girls who are 5'1" 105 lbs. and look completely normal, I also know girls who are 5'4" 125 and look completely normal. It depends on how tall you are and how you carry your weight. This being said, I know that's not the kind of answer you want so:
If you are 4'9"-5'3" - I would say you are anywhere in the normal to slightly no range. Don't worry, it is by no means overweight.
5'3" + - you are probably a little too skinny (I know, "too skinny?????") My recommendation would be to take up running. Even though it is cardio, when your body weight is that low, cardio can actually help you gain a few HEALTHY pounds in muscle (probably 2-8) while burning fat.

my 12 year old son whos on the wrestling team is 92lbs and isnt the smallest on the team.. youre probably a bit over.. Dont thumb me down because i told the truth.. You people that just want to be "nice" are not helping, This person deserves the correct answer. You are all adding to the obesity rate..

You're underweight, but it can depend on your height. And why does everyone use pounds? What happened to stones, which are easier to figure out?

@ John - Your kid is really underweight, especially since he is a boy. Learn your facts, then come back.

enter you weight, enter your height, and hit calculate!

@ Leila
You're right! I use stones! It's far simpler.


Anyway, Leila's right; you are underweight, but not dramatically. Of course, if you're fairly short then it's perfectly normal.

Check it against your height

it depends on your height, but i'd say 95-125 is normal.
