About how tall should you be at age 12, about in 7th grade. And how about weight?

There is no definite answer to how tall one should be for their age. This answer will vary from person to person, from gender to gender and from age. One can talk to their doctor to find out the exact height that is approximate for their age and gender. A 12 year old girl who is 5 feet tall should weigh between 80 and 110 pounds. Of course some girls will weigh more and some will weigh less, it does not mean that they are fat or too skinny. A 12 year old boy who is also 5 feet tall should weigh between 75 and 100 pounds. These are the weights that would place the child in the 50 percentile of all children their age.
