BMI Calculator
Calculate your Body Mass Index (BMI) in seconds. BMI is a quick height-to-weight screening metric — useful at population scale, but it doesn’t tell you how much of your weight is muscle vs fat.
Calculate your BMI
BMI uses height and weight only (it’s not a body fat % measurement).
Your BMI

Healthy weight range for your height: 125.3–168.6 lb
What does BMI mean?
BMI is calculated from your height and weight. It’s commonly used as a simple screening tool, but it can misclassify people who are very muscular, very lean, or have atypical body composition.
If your goal is physique tracking, BMI is best paired with something that reflects body composition — like tape measurements, a photo-based body fat estimate, or progress photos over time.
