Child growth chart
Add your child's weight, height and head size and see where they sit on the WHO growth curves, from birth to 19. Not medical advice: discuss it with your child's paediatrician or health centre.

On the WHO curves
Reading the chart
The 50th percentile is the middle. A child on the 85th percentile for weight is heavier than about 85 in 100 children of the same age and sex. Anywhere between the 3rd and 97th lines is the usual range.
One measurement says little. What doctors watch is the line over time: most children roughly follow one curve. Crossing curves up or down, or a flat line, is worth asking about.
Weigh in light clothes, no shoes or nappy if you can. Under 2 years, length is measured lying down; from 2, height is measured standing. Lying length is about 0.7 cm more, and the page adjusts for it.
Birth to 5: the WHO Child Growth Standards, built from healthy, breastfed children in Brazil, Ghana, India, Norway, Oman and the USA. From 5 to 19: the WHO 2007 growth reference. For children 5 to 19, WHO counts a BMI more than 1 SD above the median as overweight and more than 2 SD as obesity.
These curves are for children born at full term. If your baby was premature, or has a condition that affects growth, ask the doctor how to read the chart.
In July 2024 the Ministry of Health and Prevention ran a workshop with WHO to train healthcare workers in applying WHO's child growth standards. Your child's own health record and doctor are the reference that counts.
This chart is for understanding, not diagnosis. Discuss your child's growth with your child's paediatrician or health centre, and go sooner if your child is unwell, not feeding or eating, or losing weight.

LMS values taken from WHO's own anthro and anthroplus software packages (github.com/WorldHealthOrganization) and checked against the WHO percentile tables on who.int (for example: boys' weight at 12 months, median 9.6479 kg, 3rd–97th 7.8–11.8 kg; girls' height at 48 months, median 102.7312 cm; girls' BMI at 10 years 6 months, median 16.9136). Z-scores use the WHO LMS formula, with WHO's adjustment beyond ±3 SD for weight and BMI, and the 0.7 cm length/height adjustment. WHO fact sheet "Obesity and overweight" (cut-offs for 5 to 19 years).
