Before you rely on this
Not a medical assessment. A single measurement means far less than the trend across visits: a child steady on the 10th percentile is usually growing well, while crossing bands may matter more. Home measurements are less precise than clinic ones, and premature babies are assessed on corrected age. Your doctor or polyclinic interprets growth, using the charts in your Child Health Booklet on HealthHub. Reference: WHO child growth standards, tables checked .

What does the 50th percentile mean?
Half of children in the WHO reference group of the same age and sex measure less, and half measure more. Any percentile can be healthy; the trend over time matters most.
Why use the WHO standards?
They are the international standards for birth to 5 years. The charts in the Child Health Booklet (December 2025 edition) are Singapore charts from a 2000 National Healthcare Group Polyclinics study. So a percentile here can differ a little from the one your clinic plots.
