What is Body Mass Index?
Body Mass Index (BMI) is a sophisticated yet simple tool that uses height and weight to estimate body fat. It stands as the global standard screening tool for weight-related health risks, providing a rapid assessment of your physical stature relative to health benchmarks.
The Clinical Formula
BMI = weight (kg) / height (m)²
For those using imperial measurements, the formula is:703 × weight (lbs) / height (in)²
Common Questions
How accurate is BMI as a health measure?
While BMI is a useful screening tool, it has limitations. It doesn't distinguish between muscle and fat. Athletes with high muscle mass may have a high BMI despite having low body fat. It's best used alongside other health indicators.
Does BMI apply to everyone?
The standard BMI categories are designed for adults age 18 and older. For children and adolescents, BMI is interpreted differently using age and sex-specific growth charts.
Why does my BMI category matter?
Research shows that people in the overweight and obese categories may be at higher risk for certain health conditions, including heart disease, type 2 diabetes, and high blood pressure.
