What is the average weight for a 5' 4 13-year-old girl?

* The average weight for a girl who just turned 13 in America who are 64 inches tall is somewhere around 115-125 pounds. * A girl who is exactly 13 in America who is 64 inches tall is at the 75th percentile for height; this would correspond to a weight of around 115 pounds. Not everyone is at the same percentile for height and weight, however, so it's more important to stay on the same growth "curve" that you have been on. * For more information about weight in relation to height and body composition, and how to work this out, please see the page link, further down this page, listed under "Related Questions." ----
