Answer A 12 year old boy who is 4'9 should weigh 85-90 pounds. I'm 12 and am 4'9 and weigh 76 pounds.
A 9 year old boy who stands 4 feet 8 inches tall should weigh between 85 pounds and 107 pounds. Obesity for this height begins at 133 pounds.
This depends on your height, build and gender.

Not 83! It depends! Are you a nine year old? Or 13 years old? It varies! 9 can be about 60-82lbs 10 can be about 66-85lbs 11 can be about 70-91lbs 12 can be about 80-95lbs 1…3 can be about 85-103lbs Don't really rely your life on this and say "OMG im too heavy!" These are approximations, and estimations, I didn't get this from actual data, its off of knowledge of data (lol). Notice this: Usually someone 4'9" should not weight less than 62lbs or more than 100lbs, varying by age. You can't expect a 13 year old of the same height as a nine year old to be the same weight! The thirteen year old has four extra years of food in him! It's just virtually impossible. :P
