This calculator is designed to give the body Mass Index rating, including the BMI notation as given by The Panel on Energy, Obesity, and body Weight Standards published by American Journal of Clinical Nutrition. It is broken down into age groups of youth: Less than 35 and 35 and over.
(A second calculator is provided for metric data entry.) Your metric weight and height will also be calculated. Click "Calculate".

Enter your height in feet and inches. If you are exactly 5 feet or 6 feet tall, put a "0" in the inches box. The results can be calculated incorrectly if you leave the inches box empty. Enter your weight. Enter your age, in years; then click "Calculate" for the results. The BMI and associated notations are displayed. An X in either the below 35 age group or 35 and above age group indicates that is YOUR notation. An X in the below 35 group indicates that your BMI is figured on the national Youth Scale (Under 17). There is a lot of latitude in the Youth Scale, depending on frame size. If a young person is at or near adult height and stature but is only 16 or less, PUT in the age as 17.
