CDC Height for Age Percentiles for Boys (2 - 20 years)
Calculate Z-score and percentile
About
This tool is based on data from the Centeres for Disease Control (CDC) Growth Charts released in 2000. The CDC growth charts are recommended for use in clinical practice and research to assess size and growth in U.S. infants, children, and adolescents.
In some cases, including consideration of pharmacotherapy, more stringent definitions of short or tall stature are used, with thresholds of <3rd percentile or <1st percentile for short stature, and >97th or >99th percentile for tall stature.
At the extremes (>97th percentile or <3rd percentile), small differences in percentiles represent clinically important differences in BMI. At these extremes, the z-score is a more precise reflection of how far the measurement deviates from the mean, and is a useful tool for tracking changes.
