How to Use the Baby Growth Chart
Enter age in months, sex, weight and length, then press Estimate Percentiles. The result updates as you type.
How it works
Reference medians and spread come from simplified WHO growth data for ages 0–24 months.
Each measurement becomes a percentile against the reference for that age and sex.
Values are rounded and are a rough guide, not a clinical assessment.
