What is the average weight of a 14-year-old?

According to the Centers for Disease Control and Prevention's growth charts, a 14-year-old boy's average weight is 113 pounds, while that of a 14-year-old girl is 109 pounds. However, it is more important that a child show steady growth rather than focus on a certain number, according to Babycenter.

Weight charts for children are a good tool to give a general picture of how kids are growing and developing physically. The national averages for children of the same age serve to determine if a child is following a healthy pattern of growth and not to measure whether that child is too fat or too thin, states Babycenter.
