Army Waist-to-Height Ratio
Military Body Fat Calculator
Calculate your current Army body composition status using the 2026 Waist-to-Height Ratio standard.
The Army replaced the old height/weight screening and circumference-based body-fat tape test with WHtR in July 2026.
2026 Army WHtR calculator
Military Body Composition Calculator
Enter waist circumference and height, then click Calculate. The Army standard is a recorded waist-to-height ratio below, but not equal to, 0.550.
Your WHtR, Army standard status, and distance from the 0.55 threshold will appear here.
New Army standard
2026 Army Body Composition Standard
In July 2026, the Army adopted Waist-to-Height Ratio (WHtR) as the sole authorized body composition assessment. The compliance benchmark is less than 0.55; exactly 0.550 does not meet the standard.
Army policy records the value to three decimal places by disregarding digits after the third decimal rather than rounding them. That means .549 passes and .550 fails.
The recorded three-decimal WHtR must remain below 0.550.
Soldiers are screened at least twice per calendar year under the current policy.
The current policy records WHtR on DA Form 5500 and in ATIS.
Simple ratio
How the Military Body Fat Calculator Works
The current Army calculation is straightforward: WHtR = waist circumference ÷ height. Both measurements must use the same unit.
Measurement accuracy
How to Measure Your Waist Correctly
For Army WHtR screening, waist circumference is measured at the navel / belly button level. Use a consistent horizontal measurement and avoid estimating from clothing size or a belt measurement.
An official Army screening follows Army measurement procedures and may include a same-duty-day confirmation measurement by a different team if the initial result does not meet the standard.
Standing height
How to Measure Your Height
Use standing height without shoes. For Imperial input, enter feet and remaining inches; the calculator converts them to total inches before dividing waist by height. Metric users can enter both measurements directly in centimeters.

Understanding Your WHtR Result
A recorded WHtR below 0.550 meets the Army body composition standard. A recorded value of 0.550 or greater does not meet the standard and requires the Army's confirmation process during official screening.
The calculator also shows how far your raw ratio is below or above 0.55 and the waist measurement equal to 55% of your height. That contextual information is for planning only; official measurement and administrative action are controlled by Army policy.
Old vs. current
Military Body Fat Calculator vs. Traditional Body Fat Percentage
The page keeps the familiar “Military Body Fat Calculator” name because that is what many users search, but the Army no longer uses the traditional tape-test body fat percentage as its current body composition assessment.
Height/weight screening, circumference-based tape methodology, and supplemental body-fat assessments are no longer the authorized current standard.
One waist measurement at the navel divided by height, with a universal compliance threshold below 0.550.
July 2026 change
Important 2026 Army Policy Update
Army Directive 2026-13 replaced the previous body composition screening framework with WHtR. The Army's July 7, 2026 announcement describes the change as immediate and states that all Soldiers will undergo WHtR assessment twice per calendar year.
The current policy also rescinds the former AFT-based body-composition exemption: a Soldier's AFT score does not exempt them from meeting the WHtR standard.
Additional questions
Military Body Fat Calculator FAQ
Does a WHtR of exactly 0.55 pass?
No. The Army standard is less than, but not equal to, 0.55. A recorded 0.550 does not meet the standard.
Can I use centimeters instead of inches?
Yes for this calculator. WHtR is unitless as long as waist and height use the same unit. The official Army record uses inches.
Does passing the AFT exempt me from the body composition standard?
No. Army Directive 2026-13 rescinded the prior AFT-based exemption.
What form is used to record the Army WHtR?
The current policy records WHtR on DA Form 5500 and in the Army Training Information System. DA Form 5501 is no longer used.
Does the new Army WHtR standard apply across Army components?
The current policy describes WHtR as the Army body composition assessment for Soldiers, with some differences in medical-exam procedures among Regular Army, AGR, National Guard, and Reserve personnel.
Is this calculator an official Army measurement?
No. It is an independent informational calculator. An official result requires Army measurement procedures and authorized recording.
