About this calculator

The Army tape test estimates body fat from height and circumference measurements in inches. Maximum allowed body fat depends on age and sex, ranging from 20% to 26% for men and 30% to 36% for women.

Formula

Men: %BF = 86.010·log₁₀(waist−neck) − 70.041·log₁₀(height) + 36.76 Women: %BF = 163.205·log₁₀(waist+hip−neck) − 97.684·log₁₀(height) − 78.387 (inches)
