How to use this tool?
This calculator estimates your baby's weight, height, and head circumference percentiles based on WHO growth standards. Here's how to use it:
- Select Gender – Choose "Male" or "Female" from the dropdown.
- Enter Age – Input your baby's age in months (0 to 60). Use decimals for partial months (e.g., 6.5).
- Enter Measurements – Provide the following in metric units:
- Weight in kilograms (kg)
- Length/Height in centimeters (cm)
- Head circumference in centimeters (cm)
- Click "Calculate Percentiles" – Results will appear below showing each measurement's percentile and a descriptive comment (e.g., "Normal", "Low").
Understanding the results: A percentile shows how your baby compares to others of the same age and gender. For example, a weight at the 60th percentile means your baby weighs more than 60% of healthy babies. The comment indicates if the measurement is within typical ranges.
Note: This calculator uses simplified reference data for demonstration. For clinical decisions, consult your pediatrician.
