A single measurement is just one data point — your child's doctor looks at growth over time, not one percentile. This tool doesn't adjust for premature birth and isn't a substitute for professional medical advice.
Percentiles are calculated using the official WHO Child Growth Standards (birth to 24 months) and CDC Growth Charts (2 to 20 years).
