BMI Calculator

A Body Mass Index Calculator is a good indicator of healthy or unhealthy weight. A low BMI indicates you are underweight, while a high BMI means you may be overweight or obese. See the reference below to see your relative position.

Your Weight:
Your Height:


If your BMI is less than 19, you are underweight
if your BMI is between 19 and 25, your BMI is desirable
if your BMI is between 26 and 29, you are prone to health risks
If your BMI is between 30 and 40, you are obese
If your BMI is over 40, you are extremely obese

Your BMI is a measurement of your body weight based on your height and weight. Although your BMI does not actually "measure" your percentage of body fat, it is a useful tool to estimate a healthy body weight based on your height. Due to its ease of measurement and calculation, it is the most widely used diagnostic indicator to identify a person's optimal weight depending on his height. Your BMI "number" will inform you if you are underweight, of normal weight, overweight, or obese. However, due to the wide variety of body types, the distribution of muscle and bone mass, etc., it is not appropriate to use this as the only or final indication for diagnosis.
