BMI is a simple health metric calculated from your height and weight. It estimates body fat and helps identify if you are underweight, at a healthy weight, overweight, or obese. While it's not a direct measure of health or body composition, it's widely used by doctors and recommended by organizations such as the World Health Organization (WHO), NHS, CDC, and others.
Your BMI result will appear alongside a color-coded chart and range guide. The result includes your numerical BMI value, a category (e.g. Healthy weight, Overweight), and for children, a percentile based on age and gender. The ranges are adjusted for different countries and populations.
