BMI Calculator
Your Body Mass Index is a quick way to check whether your weight is in a healthy range for your height. It is not perfect — it does not account for muscle mass or body composition — but it is a useful starting point for most people.

About BMI
BMI is calculated by dividing your weight in kilograms by the square of your height in metres. While it is a helpful screening tool used by the NHS, it does not distinguish between muscle and fat. Athletes may have a high BMI while being perfectly healthy.
For a more complete picture, consider measuring your waist circumference or body fat percentage alongside BMI.
