Formula & method US Army Tape Test Logarithmic Formulas
Male %BF = 86.010 × log10(Waist − Neck) − 70.041 × log10(Height) + 36.76
Female %BF = 163.205 × log10(Waist + Hip − Neck) − 97.429 × log10(Height) − 78.387 (in inches).
Example Male, height 69 in, neck 15 in, waist 32 in → %BF ≈ 15.2% (Passes for age 25).
Key insights The US Army Body Composition Program (AR 600-9) uses circumference measurements to estimate body fat. Maximum allowable body fat standards for males: 20% (17–20 yrs), 22% (21–27 yrs), 24% (28–39 yrs), 26% (40+ yrs). Maximum allowable body fat standards for females: 30% (17–20 yrs), 32% (21–27 yrs), 34% (28–39 yrs), 36% (40+ yrs).
