Our Growth Percentile Calculator is a general educational tool only; it is not the last word on how your child is growing. This calculator is not a substitute for having a physician monitor your child's growth during regularly scheduled examinations. If you have any questions about your child's growth patterns, please ask your child's doctor.

These percentiles were compiled using the latest growth chart data from the National Center for Health Statistics, U.S. Public Health Service (released in November 2000). The numbers are based on five health surveys done in the United States between 1963 and 1994. The data takes into account the combined growth patterns of babies from all races and ethnicities and those who have been breast- and formula-fed.
