Healthy weight

Being a healthy weight is essential to good health. It helps you move around easily, take part in everyday social activities and helps prevent illnesses. 

What is a healthy weight?

For adults

A Body Mass Index (BMI) is used to test whether you are a health weight. This calculate your weight divided by your height. 

This table shows the BMI levels.

Age group Weight
Less than 18.5 Underweight
Between 18.5 and 24.9 Healthy weight
Between 25 and 29.9 Overweight
Between 30 and 39.9 Obese
Over 40 Very obese

You can use the NHS Choices Health Weight Calculator to measure your BMI.

For children

For children the calculation is more complicated, their BMI needs to be compared to other information about how they grow at different ages. 

There is a national programme to measure children's weight in schools.
