About the Army Body Fat Calculator

The tape test estimates body fat percentage using simple circumference measurements, similar to methods used by military fitness assessments.

Formula Used

Men: BF% = 495 / (1.0324 - 0.19077×log10(waist-neck) + 0.15456×log10(height)) - 450 Women: BF% = 495 / (1.29579 - 0.35004×log10(waist+hip-neck) + 0.22100×log10(height)) - 450

How It Works

This calculator applies the standard circumference-based formula using neck, waist, height, and (for women) hip measurements to estimate body fat percentage.

Step by Step

  1. Measure neck and waist circumference in centimetres (add hip for women).
  2. Enter your height along with these measurements.
  3. The tape-test formula converts these into an estimated body fat percentage.

Worked Example

Example: A man, 175 cm tall, neck 37 cm, waist 82 cm:

BF% = 495 / (1.0324 - 0.19077×log10(82-37) + 0.15456×log10(175)) - 450 ≈ 14.9%

Frequently Asked Questions

How is this different from the Navy method?

It uses the same underlying circumference formula that the US Navy method is based on, commonly referenced for military-style tape tests.

How should I measure my neck?

Measure just below the larynx (Adam's apple), keeping the tape level and snug but not tight.

Is this test used for official military fitness standards?

This calculator gives an estimate for personal reference; official assessments follow specific service regulations and measurement protocols.
