About Baby Weight Percentile

This tool calculates your baby's weight and height percentiles using WHO (World Health Organization) growth charts for ages 0–24 months. Percentiles show how your baby's measurements compare to a reference population of healthy children of the same age and sex. A result at the 50th percentile means your baby is exactly at the median. Values between the 15th and 85th percentile are generally considered within the normal range, though your pediatrician is always the best judge of healthy growth for your individual child. Growth trends over time matter far more than any single measurement.
