Growth charts for children, including those that demonstrate weight-for-age and weight-for-length percentiles, can be downloaded for free on the Abbott Nutrition and Centers for Disease Control and Prevention websites. These charts are accessed using a program such as Adobe Reader.
For children under the age of 24 months, the CDC and the American Academy of Pediatrics recommend the use of the international growth charts distributed by the World Health Organization, rather than the growth charts that had been previously disseminated by the CDC. Both the CDC and the AAP assert that the WHO international growth charts provide a better model for optimal growth for children in the United States under two years old.
To find growth charts for children older than 24 months, the CDC's website displays charts for children and adolescents up to 20 years old. There are weight charts specifically for girls and for boys, as well as charts for both sexes. There are also weight charts available in Spanish and French, as well as charts for children with special needs. The CDC and the AAP recommend that parents consult with medical practitioners regarding the use of weight and growth charts in determining the health of their children.
