Body mass index (BMI) chart Health Policy team The BMI centile is a simple and reliable indicator of a healthy body weight in childhood. Where severe overweight or underweight is a concern, or where there is a need for monitoring weight over time, BMI can be calculated and plotted on this chart.
It is important also to plot the height and weight separately on the main 2-18 years chart. There is also a BMI centile look-up on the standard 2-18 chart for less complex cases.
