How to read this chart

Range and measurements

WHO · Birth–24 months. Weight in kilograms and length in centimeters, with separate curves for boys and girls.

This page displays the first 24 months of the WHO standard.

What a percentile means

P50 is the median: approximately half of the reference group has a smaller measurement and half has a larger one. P10 means approximately 10% has a smaller measurement at the same age and sex.

Add a measurement

Browse the curves without entering data. To add your point, select the sex, open “Add measurements,” and enter the dates and measurements. The red point represents the measurement; use the controls to switch between weight and height or length.

Source and interpretation

A single percentile is not a diagnosis or a growth target. Interpret measurements alongside growth over time and clinical context.
