About Growth Percentiles
Growth percentiles compare your baby's measurements to other babies of the same age and gender. A 50th percentile means your baby is average, while 75th percentile means they're larger than 75% of babies their age.
Important: Percentiles are just one tool. Your baby's individual growth pattern, family genetics, and overall health are more important than any single measurement.
This calculator uses WHO Child Growth Standards, which are based on healthy, breastfed babies from diverse populations worldwide.
Understanding Baby Growth Percentiles
What Do Percentiles Mean?
A percentile tells you what percentage of babies are smaller than your baby. Our calculator uses WHO Child Growth Standards, based on healthy, breastfed babies from diverse populations worldwide.
Percentile Examples
- • 50th percentile: Average-sized (half smaller, half larger)
- • 75th percentile: Larger than 75% of babies
- • 25th percentile: Smaller than 75% of babies
- • 10th-90th percentile: Normal healthy range
Important Considerations
- • Individual growth patterns vary significantly
- • Genetics play a major role in your baby's size
- • Growth trends over time matter more than single measurements
- • Babies often cross percentile lines naturally
When to Consult Your Pediatrician
- • Consistently below 3rd or above 97th percentile
- • Sudden changes in growth pattern
- • Very different weight and height percentiles
- • Any concerns about feeding or development
