First trimester growth charts are used to track progress during childhood and adolescence.
The rate of your child's growth is a crucial sign of how healthy they are. The UK-WHO growth charts let medical practitioners chart and gauge your child's development starting at birth. For further information, read about these below and download our factsheets.

An adult height predictor, a mid parental height comparator, a BMI centile lookup, and advice on the onset and progression of puberty are all included.
