Plotting Your Child's Weight-to-Age Percentile
To plot your child's weight-to-age percentile, find the age of your child on the bottom of the chart and look to the left to locate their body weight. Once you locate their weight and age, locate the corresponding shaded color on the bottom of the chart to determine your child's percentile.

A child is defined as "overweight" if their weight-to-age percentile is greater than 95 percent. A child is defined as "at risk for overweight" if their weight-to-age percentile is greater than 85 percent and less than 95 percent.
