How it works

BMI is calculated by dividing your weight in kilograms by your height in meters squared. It is a simple screening tool to classify underweight, normal weight, overweight and obesity.

How to interpret the results

A BMI between 18.5 and 24.9 is usually considered “normal”. Values below 18.5 suggest underweight; between 25 and 29.9 suggest overweight; 30 or above indicate obesity. BMI does not account for muscle mass or body composition.
