No. I am a twelve year old boy, and I am only 5'5, and I weigh 87 pounds, so no that is not fat at all.

A 12 year old boy will lose his puppy fat as he gets older. As boys grow, they tend to lean out, develop muscle and burn off the fat easier.
It has to be 29 or 30 or you will be too fat
Girls

30-75
