What Is BMI (Body Mass Index)?

BMI is a simple calculation using height and weight. While it's a quick screening tool, BMI has significant limitations: it doesn't distinguish between muscle and fat, so muscular individuals may be classified as overweight or obese.

BMI Limitations: Why It's Not Perfect

BMI cannot tell the difference between muscle mass and fat mass. A bodybuilder with 8% body fat may have a BMI of 28 (overweight). For a more accurate health assessment, use our body fat percentage calculator alongside BMI.

BMI Calculator FAQ

Is BMI accurate?

BMI is a screening tool, not a diagnostic tool. It's accurate for sedentary individuals but misleading for muscular people. Combine with body fat percentage for better assessment.

What is a healthy BMI?

A BMI between 18.5 and 24.9 is considered healthy for most adults. However, this range may not apply to athletes, elderly, or certain ethnic groups.
