Calculate Your Body Mass Index (BMI)
BMI is a widely-used screening tool that estimates body fat based on your height and weight. Enter your measurements to calculate your BMI instantly.
BMI Categories
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5 to 24.9
- Overweight: BMI 25.0 to 29.9
- Obese: BMI 30.0 and above
BMI Formula
BMI = weight (kg) / height (m)². For example, a person weighing 75 kg and standing 175 cm tall has a BMI of 24.5, which falls in the normal weight range.
Limitations of BMI
BMI does not distinguish between muscle and fat mass. Athletes with high muscle mass may have elevated BMI despite low body fat. Consider using additional measurements like waist circumference or body fat percentage for a more complete picture.
