How Body Fat is Measured

BMI and Body Fat Calculator

BMI shows body weight relative to height but does not distinguish between muscle and fat. Combining BMI with fat estimates gives a clearer picture.

Tape Measurements

Measuring waist, hips, and neck with a tape can estimate body fat. This method is common in Army Body Fat Calculators and athlete assessments.

Skinfold Calipers

Calipers measure the thickness of skinfolds at specific points on the body. Reliable for tracking when performed correctly.

Bioelectrical Impedance & Smart Scales

Smart scales and devices send a safe current through the body to estimate fat versus lean mass.

Military & Specialized Standards

The Army Body Fat Calculator uses standardized formulas to assess body composition for fitness and eligibility.
