Army Directive 2026-13 made WHtR the only Army Body Composition Program standard, with a passing ratio below 0.55. It rescinded the tape test and its body fat percentages. Official measurements are taken by your unit, with a confirmation measurement if the first one does not meet the standard. This tool is unofficial.

Quick Answer

The Army now uses waist-to-height ratio instead of body fat percentage. Divide your waist by your height in the same units. The standard is a ratio below 0.55. A Soldier who is 5 ft 10 in (70 in) with a 34 inch waist has a WHtR of 0.486, which meets the standard. At 70 inches tall, the waist must be under 38.5 inches.

How This Army Body Fat Calculator Works

Enter your height and waist measurement. The calculator divides waist by height to find your waist-to-height ratio (WHtR), checks it against the Army standard of less than 0.55, and shows the largest waist that passes at your height. A chart lists the limit for common heights.

Quick explanation: the Army replaced the tape test and body fat percentages with one simple ratio.

  • Standard: WHtR must be below 0.55.
  • Enrollment: 0.55 or higher means enrollment in the Army Body Composition Program.
  • No challenges: other body fat methods cannot be used to challenge the WHtR result.

How to Use the Army Body Fat Calculator

  1. Choose inches or centimeters.
  2. Enter your height.
  3. Measure your waist and enter it in the same unit.
  4. Press Calculate.
  5. Read your WHtR, whether it meets the standard and your maximum waist.

Core Formulas

  • WHtR: waist ÷ height (same units)
  • Pass: WHtR < 0.55
  • Largest passing waist: just under 0.55 × height

Key Terms

  • WHtR: waist-to-height ratio, waist divided by height.
  • ABCP: Army Body Composition Program.
  • Army Directive 2026-13: the policy that made WHtR the Army's body composition standard.
  • DA Form 5500: the form where the WHtR result is recorded.
  • Confirmation measurement: a second measurement by a different team if the first one fails.

Worked Example

A Soldier is 6 ft 0 in (72 in) tall with a 40 inch waist.

  • WHtR = 40 ÷ 72 = 0.556
  • 0.556 is 0.55 or higher, so it does not meet the standard
  • The waist must be under 0.55 × 72 = 39.6 inches

Real-Life Examples

  • Before a record measurement: check where you stand and how much margin you have.
  • Setting a goal: at 5 ft 8 in (68 in), the waist must be under 37.4 inches.
  • Tracking progress: measure your waist every few weeks and watch the ratio fall.
  • Leaders: use the chart to explain the limit for different heights.

WHtR vs the Old Tape Test

  • Old method: tape measurements and weight were used to estimate body fat percentage, with limits by age and sex.
  • New method: one ratio, waist ÷ height, with the same limit of below 0.55 for all Soldiers.
  • For civilians: our Body Fat Calculator estimates body fat percentage instead.

What the Directive Changed

  • Only standard: WHtR is the sole Army Body Composition Program measurement.
  • Tables gone: height and weight screening tables are discontinued.
  • Twice a year: all Soldiers are measured at least twice per calendar year.
  • No fitness exemption: no Army Fitness Test score exempts a Soldier from the WHtR standard.

Common Mistakes to Avoid

  • Mixing units. Waist and height must use the same unit.
  • Using the old body fat limits. They were replaced by WHtR.
  • Rounding into a pass. The ratio must be below 0.55, not equal to it.
  • Pulling the tape tight. Measure snugly without squeezing.
  • Relying on a home check. Only official unit measurements count.
