BMI Calculator

Body Mass Index (BMI) is one way to measure your body fat. Based on your height and weight, the BMI calculator below can help you better understand what classification you are in and how you compare to other people with similar height and weight. BMI is only meant to apply to adult men and women and should not be used for children and teens.

BMI and Plastic Surgery

We use BMI as one factor to determine your candidacy for surgery. A stable, healthy weight prior to surgery is important both for your own safety and for the quality of your surgical results.

  • Normal: Your weight is unlikely to be a factor in whether or not you are a candidate for a procedure.
  • Underweight or Overweight: If you are either “Underweight” or “Overweight,” a more personal assessment by one of our board-certified plastic surgeons will help us to determine if you are a candidate or not.
  • Obese: For people in this category, we generally recommend reducing weight before you come in for a consultation.

For people with a BMI of 35 or more the risk of complications during and after surgery increases. At this BMI level, you are more likely to have other conditions that can affect your candidacy for surgery, including heart disease, high blood pressure, diabetes and breathing problems.
