Track this over time in GrowSenseOne point is a snapshot — the app follows the whole curve.

How it works. The WHO publishes height-for-age as five percentile bands (3rd / 15th / 50th / 85th / 97th). This tool interpolates those bands to your child's exact age, places their height between them, and converts to a percentile — the same method the GrowSense app uses. Under 5 needs a different WHO standard; ask your pediatrician. Worried about a low or dropping curve? Read is my child too short?

Educational only — not a diagnosis. A single percentile is a snapshot, not a verdict; healthy children sit at every percentile, and the trend over time matters far more than one point. If your child's height is very low, very high, or crossing downward through the bands, see a pediatrician.
