Frequently asked questions
What is BMI?
BMI stands for Body Mass Index. It's a simple calculation using your weight and height that estimates body fat and helps categorize underweight, normal weight, overweight, and obesity.
How is BMI calculated?
BMI is calculated by dividing your weight in kilograms by your height in meters squared. The formula is kg/m². For pounds and inches, use 703 × (lb / in²).
What is a healthy BMI?
For most adults, a BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or higher is obesity.
What Is Body Mass Index (BMI)?
BMI is a simple, inexpensive screening tool that uses your weight and height to estimate body fat. While it doesn't measure body fat directly, studies show it correlates moderately with direct measures. Healthcare providers use it to quickly identify potential weight issues and to assess your risk for conditions like heart disease, diabetes, and high blood pressure.

Understanding Your BMI Results
Your BMI result offers a general snapshot of your body composition. A normal BMI range is associated with lower risk of chronic disease. If your result falls outside the healthy range, consider speaking with a doctor or registered dietitian. Remember that age, muscle mass, and bone density can affect the accuracy of BMI.
