Frequently Asked Questions
What is the Body Adiposity Index?
BAI estimates body fat percentage using only hip circumference and height, without needing to step on a scale. It was developed as an alternative to BMI for estimating body fat directly.
How accurate is BAI compared to BMI?
BAI can be more informative than BMI for some people since it targets body fat specifically rather than total weight, but like BMI it does not account for age-specific changes in body composition and should be used as one data point among several.
Does BAI work the same for men and women?
The BAI formula itself is the same for both sexes, but healthy body fat percentage ranges differ between men and women, which is why this calculator asks for your sex.
What is a healthy BAI result?
General healthy body fat ranges are roughly 6-24% for men and 13-31% for women, though the exact healthy range shifts with age. This calculator gives a general category based on those standard ranges.
