Frequently Asked Questions

How is BMI calculated?

BMI is calculated by dividing your weight in kilograms by the square of your height in meters (kg/m²). It provides a quick estimate of whether your weight is in a healthy range for your height.

What do the BMI categories mean?

A BMI under 18.5 is considered underweight, 18.5–25 is normal, 25–30 is overweight, and 30 or above is considered obese. These ranges are general guidelines and can vary by individual.

What are the limitations of BMI?

BMI doesn't distinguish between muscle and fat, so athletes or very muscular people may show a higher BMI without excess body fat. Use it as a general guide, not a diagnosis.
