About BMI Calculator
Body Mass Index (BMI) is a simple screening number that relates your weight to your height. Enter your measurements in either metric (cm / kg) or imperial (ft / in / lb) and the calculator instantly shows your BMI, the category it falls into, and the weight range considered healthy for your height.
BMI is widely used by clinicians as a quick first indicator, but it does not distinguish muscle from fat and does not account for age, sex, or body composition. Athletes and very muscular people often read as "overweight" despite low body fat. Treat the result as a starting point, not a diagnosis. Everything runs in your browser — nothing is uploaded.
⚠ Disclaimer: BMI is a general screening tool, not a medical diagnosis. It does not measure body fat directly and may be misleading for athletes, pregnant people, children, and the elderly. Consult a qualified healthcare professional for advice about your health and weight.
