Growth Percentiles (Estimated)
Based on CDC 2000 growth reference data. Percentiles are approximated using a polynomial fit to CDC median and SD tables. For clinical assessment, consult a pediatrician.
Understanding Growth Percentiles
A percentile tells you how a child compares to others of the same age and sex. A child at the 50th percentile for height is taller than 50% of children the same age. Percentiles between the 5th and 95th are generally considered within the normal range. A single measurement is less informative than a trend over time — consistent growth along any percentile curve is healthy.
