Baby growth charts for girls and boys
WHO weight, height and head circumference charts from birth to 5 years, with percentile tables by month in metric and imperial.
Why WHO growth charts?
The WHO Child Growth Standards describe how healthy children grow when they are breastfed, cared for well and not exposed to smoking. They were built from children in Brazil, Ghana, India, Norway, Oman and the United States, and are used for under-fives by most health services, including the UK and, for children under 2, the US CDC.
What a percentile means
A percentile compares your child with 100 healthy children of the same age and sex. On the 40th percentile, 40 measure less and 60 measure more. Every line between the 3rd and the 97th is normal. Read our guide to baby growth percentiles.
