About this app

Your weight doesn't tell the whole story. Body fat percentage is what actually matters for your health, fitness, and performance — and most body fat calculator apps only give you one rough estimate.

Body Fat Calculator gives you 9 research-based formulas to calculate body fat percentage from a tape measure or skinfold caliper — including Bozeera calipers. Cross-reference results from multiple methods to get the most complete picture of your body composition.

THREE FREE BODY FAT METHODS
* YMCA body fat formula — quick estimate using weight and waist
* Modified YMCA — improved body fat percentage accuracy with additional measurements
* U.S. Navy body fat method — the same formula used by the military to assess fitness

SIX PRO+ BODY FAT FORMULAS
* Jackson & Pollock 3-Site, 4-Site, and 7-Site — the industry standard for skinfold body fat testing
* Durnin & Womersley — a widely used skinfold method from exercise science research
* Covert Bailey — comprehensive body composition method using circumference measurements
* Parrillo 9-Site — the most detailed skinfold method, designed for bodybuilders and athletes

Every formula is implemented from its published source, and every one has a documented margin of error (±3–7% depending on method and measurement technique). The Jackson & Pollock and Durnin & Womersley methods come from peer-reviewed research; the U.S. Navy method from Naval Health Research Center technical reports; the YMCA methods from standard fitness-testing manuals; and Parrillo and Covert Bailey from published fitness books.
