About BMI Calculator
The BMI Calculator computes your Body Mass Index — a standard screening metric that uses height and weight to categorize whether your weight is in a healthy range. Enter your height and weight (in metric or imperial units), and the calculator shows your BMI value, your BMI category (underweight, normal, overweight, or obese), and the healthy weight range for your height. BMI is a useful screening tool but has known limitations: it doesn't account for muscle mass, bone density, or body composition, so athletes with high muscle mass may get a misleading 'overweight' result. Use BMI as one data point, not as a definitive health assessment. The calculator runs entirely in your browser.
Privacy
