Body Mass Index - Calculate your BMI

The body mass index determines the degree of your body weight. The guidelines are set up to determine if you're under weight, fit, overweight, or obese.

Calculate Your BMI

  • Multiply your weight (in pounds) times 704
  • Divide that by your height in inches
  • Divide that number by your height in inches again

Example:

  • You're 5'4" (62 inches) and weigh 160 pounds
  • 160 x 704 = 11264
  • 11264 divided by 62 = 1816.77
  • 1816.77 divided by 62 = 29.30
  • he BMI would be 29.30

Find your results:

  • 18.5 and under - Under weight, extremely active or still growing
  • 19 - 24.9 = Fit
  • 25 - 29.9 = Overweight
  • 30 + = Obese

Underweight is considered to be under a healthy weight. Most consider individuals under 18.5 to be underweight - although some authorities use a higher value of 20. It is important to note that the BMI is a statistical estimate and some individuals classified as underweight may be perfectly healthy.

Overweight is defined as weighing more than is normal, necessary, or allowed, especially having more body weight than is considered normal or healthy for one's age or build.

Obese is defined as well above ones normal weight. A person has traditionally been considered to be obese if they are more than 20 percent over their ideal weight.

The body mass index is very useful to doctors in determining relative weight to height and measures your total body fat. The BMI is an accurate measurement of body fat with the exception of people that are very muscular or have lost a lot of muscle.

You should consult your doctor before starting a weight loss program.
