BMI is a general screening tool and doesn't account for muscle mass, bone density or body composition. It isn't a diagnosis — talk to a healthcare provider for personalized advice.

How this calculator works

Body Mass Index divides your weight in kilograms by the square of your height in metres (BMI = weight ÷ height²). It's the same formula doctors and public health bodies like the WHO use for population-level screening, which is why it's the most widely quoted weight metric even though it can't distinguish muscle from fat.

Your healthy weight range above is simply the weight span that keeps your BMI between 18.5 and 24.9 at your current height — useful as a rough target, but athletes and very muscular people often read "overweight" on BMI despite having low body fat.
