What is a growth percentile?
A growth percentile tells you how your baby's weight or height compares to other babies of the same age and sex. If your baby is at the 60th percentile for weight, it means they weigh more than 60% of babies their age — and less than 40%. Any percentile between the 3rd and 97th is considered normal.
WHO vs. CDC growth charts
This calculator uses WHO (World Health Organization) growth standards, which describe how healthy, breastfed children grow under optimal conditions. The WHO charts are recommended by the American Academy of Pediatrics for children under 2 years and are used globally including in India.
When to see a doctor
Consult your pediatrician if: your baby is below the 3rd percentile, your baby has dropped more than 2 major percentile lines (e.g., from 50th to 10th) over several months, or you notice any sudden change in your baby's growth pattern. One low measurement is rarely cause for alarm — trends over time matter most.
Limitations of this tool
This calculator provides estimates based on WHO reference data and is for informational purposes only. For accurate assessments, measurements should be taken by a healthcare professional. Premature babies may need age-corrected percentiles.
