Calculate your Body Mass Index (BMI)
Body Mass Index, or BMI, is a measurement of body fat based on height and weight.
It can be calculated using pounds and inches: BMI = (weight in pounds x 703) / (height in inches x height in inches).
Or you can use the calculator below:
| BMI | Classification | Health Risk |
| Under 18.5 | Underweight | Minimal |
| 18.5 - 24.9 | Normal Weight | Minimal |
| 25 - 29.9 | Overweight | Increased |
| 30 - 34.9 | Obese | High |
| 35 - 39.9 | Severely Obese | Very High |
| 40 and over | Morbidly Obese | Extremely High |
If you have a BMI of 40 or greater, or a BMI of 35-39.9 and also have an obesity related medical condition such as diabetes, high blood pressure, or sleep apnea, you may be a candidate for weight loss surgery.
