About BMI

Body Mass Index (BMI) is a numerical value calculated from your weight and height. It provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.

Note: BMI is not a diagnostic tool. It doesn't measure body fat directly, and it doesn't account for factors like muscle mass, bone density, or overall body composition. Athletes with high muscle mass may have a high BMI without increased health risks.


The BMI Calculator is a simple tool that helps you find your Body Mass Index. BMI shows if your weight is healthy for your height. It helps you understand if you are underweight, normal, overweight, or obese.

What is BMI?

Body Mass Index (BMI) is a number that is calculated using your weight and height. It’s used by doctors and health experts to see if a person has a healthy body weight. A higher BMI can mean too much fat in the body, while a lower BMI might mean not enough fat.

BMI Formula

BMI = Weight (kg) / Height (m)2

If you use pounds and inches:

BMI = (Weight (lbs) / Height (in)2) × 703

BMI Categories

BMI under 18.5: Underweight

BMI 18.5 – 24.9: Normal weight

BMI 25 – 29.9: Overweight

BMI 30 and above: Obese

Why is BMI Important?

BMI gives you a quick idea about your body weight. It can help you take steps to stay fit and avoid problems like heart disease, high blood pressure, or diabetes. However, BMI does not show muscle vs fat, so it’s just a basic guide.
