The American Body Composition Calculator for Individuals

The American Body Composition Calculator (ABCC) uses information about your height, weight and other body measurements along with age, race and sex to determine how much of your body is fat. Below you can provide as few as 5 or as many as 14 factors. Generally, the more information you provide, the more accurate the calculated results will be.

For individuals interested in obtaining the highest degree of accuracy, proper body measurement techniques are detailed in the National Health and Nutrition Examination Survey’s Anthropometry And Physical Activity Monitor Procedures Manual.

Percent body fat can be calculated for large research samples by accessing the American Body Composition Calculator for Researchers on the ABCC homepage.

Note: The body composition calculator is not accurate for individuals who are less than 8 years of age, are less than 3’6” or more than 6’5” tall, weigh less than 42 or more than 300 pounds, are pregnant, have had sex reassignment hormone therapy, or have had an amputation other than fingers or toes.
