Read the percentile curves and exact-day values. Optionally enter a measurement with its unit and, for length/height, how it was taken.

Export a selected-day CSV or the daily table. Download the original WHO data, transformation and GPL license, or keep a JSON project backup.
Before you start
Where is my project saved?
Projects are saved in this browser for this site account. Download a JSON backup before changing devices or clearing browser storage.
What does this reference show?
The WHO Child Growth Standards distribution by age and sex. This app does not diagnose a child, assign a clinical label or apply a prematurity correction. A health professional can assess a series of reliable measurements in context.
Why does length change to height?
WHO uses recumbent length through day 730 and standing height from day 731. When your measurement type differs, the comparison adds or subtracts 0.7 cm and shows the adjustment explicitly.
Does it need an AI service?
No. The reference data, chart and calculations run locally in the browser. The data source is the pinned WHO anthro v1.1.0 release, not a live feed.
Can I resume later?
Reopen the saved project on this browser and account, or restore its JSON backup. Keep backups in a place you trust because they include your supplied material.
