The results are given in percentiles. Percentiles are numbers that help show a child's growth compared to other children of the same age. If your childs height is at the 75th percentile, this means that he is as tall or taller than 75 percent of children his age. It also means that 25 percent of the children his age are taller. These numbers represent the latest growth chart data from the National Center for Health Statistics.

This tool is intended to give you a general idea about how your child is growing. It is not a substitute for having a physician monitor your child's growth during regular checkups. Keep in mind that kids grow at their own pace and that there is a wide range of healthy sizes. If your child was born prematurely and had a very low birth weight, this tool will not accurately reflect his growth. Please talk to your child's doctor if you have any questions or concerns about your child's size.
