Body Mass Index (BMI)

Body Mass Index (BMI) Calculator

The Body Mass Index (BMI) is a measure of body fat based on your height and weight and determines your weight category (see chart below). It is also used as a tool to determine if you are a candidate for weight loss surgery. Use the BMI calculator below:


Weight category BMI kg/m2 
Underweight <18.5
Normal 18.5-24.9
Overweight 25-29.9
Obesity 30-34.9
Severe Obesity 35-39.9
Morbid Obesity >=40
Super Obesity >=50

According to the National Institute of Health, you can be a surgical candidate if you have a BMI of 35 kg/m2 with at least one co-morbidity or BMI 40 kg/m2.
