Pediatric growth charts, measuring standards for height and weight, can be found online at the websites for the Centers for Disease Control and Prevention and the World Health Organization. Both organizations recommend using the WHO growth chart for infants up to age two.
The WHO growth chart is considered superior for infants because it contains a better description of physiological growth during infancy and is based on a higher-quality study of infants for the purpose of creating growth charts. However, the WHO growth chart only goes to age five. The CDC and the WHO use similar methods from age two through five and the CDC chart provides data to age 19.
