Body Mass Index is a screening tool that estimates body fat based on your height and weight. It is calculated by dividing your weight in kilograms by the square of your height in meters. The resulting number falls into one of four categories: underweight (below 18.5), normal weight (18.5 to 24.9), overweight (25 to 29.9), or obese (30 and above).
This calculator supports both imperial units (feet, inches, pounds) and metric units (centimeters, kilograms), and shows you the healthy weight range for your height. The visual scale gives you an intuitive sense of where your BMI falls relative to the standard categories.
It is important to understand that BMI is a general screening tool with limitations. It does not distinguish between muscle mass and fat mass, so athletic individuals with significant muscle may register as overweight despite having low body fat. It also does not account for age, gender, bone density, or fat distribution. For these reasons, BMI should be used as a starting point for health assessment rather than a definitive diagnosis. Always consult with a healthcare professional for personalized medical advice.
