Calculating your Body Mass Index, or BMI, is one way to gauge your weight. This BMI calculator is based on a standard formula that returns a ratio of your height to your weight. This whole number between 1 and 100 can be compared general ranges health professionals use when they determine whether a patient is obese.
This formula does not consider the relative proportions of bone, muscle, and fat in your body. It doesn’t tell you what your body fat percentage is. If you are older or have lost muscle, the formula may underestimate body fat levels. If you are lean with toned muscles and strong bones, your BMI may be high. So fit athletes may be classified as overweight or even obese even though they are healthy. For those of us with higher amounts of body fat, this calculator can be used as a tool in weight management goals.
Use your BMI number to determine which of the BMI categories you fall into:
Normal Weight: 18.5 – 25
Overweight: 25 – 30
