There is no Avrage Weight for any age. Everyone's body is diffrent and your weight has to do with alot of things with your body , esp for a girl, for example : 1. Bone size and densety 2. What you eat 3. Your period And many others . The best thing you can do is go have a chat with your docter. They will be able to tell you if everything is working good and your healthy.
i think your weght is fine if your happy with it, dont let other tell you different -i know you can do a BMI count, http://funadvice.com/r/3js2v63kmq - that measures your body mass index, i think, personally its incurate because it really depends on your body type. (not just a basic height ad weight)
There really isnt average weight or average height everyone grows differently at their own pace. This could be from genetic reasons or natural reasons. I don't understand where they get this average stuff . "The average person eats this''.
I'd say around 115-130lb I'm 5'12 ( and yes, it's six feet ;) lmfaoo) and i weigh 138
i wouldnt say average but anything between 120-135 is usaually about right
between 7 and 10 stone
