Body Mass Index (BMI) is a simple numerical measure of body weight relative to height. While it doesn't distinguish between fat and muscle mass, BMI is widely used as an initial screening tool to identify potential weight-related health risks. Use the calculator below to check your BMI instantly.
BMI provides a general indication of whether your weight falls in a healthy range relative to your height. The standard categories are: underweight (below 18.5), normal weight (18.5-24.9), overweight (25-29.9), and obese (30+), with obesity further classified into three classes based on severity.
While BMI is useful as a screening tool, it has important limitations. It doesn't account for muscle mass (a muscular person may have a "high" BMI without excess fat), bone density, age, sex, or where fat is distributed on your body. Waist circumference, body composition analysis, and other clinical measures provide a more complete picture of weight-related health risk.
A BMI of 30 or higher — or 27 or higher with weight-related health conditions — generally qualifies patients for physician-supervised medical weight loss, including GLP-1 medications like semaglutide and tirzepatide. Insurance coverage for weight loss treatment is often tied to BMI thresholds, which is one reason your provider documents this measurement during your evaluation.
