Question: how much should you weight at 12 years old?
Answer: The CDC also reports that a 12-year-old girl's weight is usually between 68 and 135 pounds, and the 50th percentile weight for girls is 92 pounds. If your child is in the 50th percentile for weight, it means that out of 100 children their age, 50 may weigh more than they do and the other 50 may weigh less.
