About this tool
Body Mass Index is a simple screening measure that uses height and weight to estimate whether a person is underweight, normal weight, overweight, or obese. It is useful for tracking general trends, though it does not directly measure body fat or account for muscle mass.
BMI is most meaningful when tracked over time. Pair it with a healthy diet, regular movement, and medical advice for a complete picture.
