BMI Calculator

Body mass index (BMI) uses height and weight to work out if a user is a healthy weight, underweight or overweight. This tool calculates a user's body mass index. The formula to calculate this is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in metres squared.

BMI is not a perfect measure of overall health. However, it could be used as a starting point for further discussion with a doctor.

The adult BMI doesn't take into account age, sex or muscular build.

This means that:

Older adults can have a healthy BMI but still have too much fat. Older adults usually have more body fat than younger adults.
Women can have a healthy BMI but still have too much fat. Women tend to have more body fat than men with the same BMI.
Those from Black and Asian backgrounds and certain other ethnic groups are at a greater risk of health conditions such as type 2 diabetes and cardiovascular disease at a lower BMI than White Europeans.
An athletic adult with a lot of muscle may have a high BMI but not be overweight. This is because BMI can’t tell the difference between fat and muscle.
Pregnant women should use their pre-pregnancy weight to work out BMI. Using pregnancy weight may not be accurate.
