Army Body Fat Calculator 2026: Waist-to-Height Ratio Check
The Army no longer scores body fat for the Army Body Composition Program (ABCP): Army Directive 2026-13 made the waist-to-height ratio (WHtR) the only authorized standard (army.mil reports that it replaced the tape test) and says, "The use of height and weight screening tables is discontinued." So this page checks your ratio against the directive's 0.55 rule instead of estimating body fat. See also the Army height and weight standards page and the AFT calculator.

Army WHtR calculator
Your measurements
The starting numbers are an example, not a goal. Replace them with your measurements. Use up to 3 decimals.
Waist-to-height ratio and the 0.55 standard
Waist ÷ height
0.5143
Meets the standard (under 0.55)
Exact quotient: 0.51428571. The result compares this exact quotient with 0.55; the 4-decimal figure above is for display only.
At a height of 70 inches, 0.55 × height = 38.5 inches. The waist must be under 38.5 inches; a waist of exactly 38.5 inches does not meet the standard. The largest waist in tenths of an inch that is still under is 38.4 inches.
Your waist of 36 inches is 2.5 inches under 38.5 inches.
Army Directive 2026-13 and army.mil do not state a rounding rule or a tape-reading increment. This calculator never rounds before deciding, and your unit's official measurement decides.
What the directive says about the tape test and body fat
Army Directive 2026-13 says:
“The WHtR is adopted as the sole measurement for all Soldiers.”
“The use of height and weight screening tables is discontinued.”
“No secondary or supplemental body composition methods (such as the circumference-based tape test or other body fat assessments) are authorized for the purpose of challenging the results of the WHtR.”
army.mil, in an article by Army Public Affairs dated July 7, 2026, reported:
“The Army has replaced the long-standing height and weight tables, circumference-based tape test, and supplemental body fat assessments with the waist-to-height ratio (WHtR) health assessment tool.”
The standard and how this calculator decides
“The standard is a WHtR of less than and not equal to 0.55.”
The calculator divides your waist by your height and compares that exact quotient with 0.55. Less than 0.55 meets the standard; exactly 0.55 or more does not. It never rounds the ratio before deciding. It shows the ratio to 4 decimals for display only, and shows the exact quotient beside it.
Army Directive 2026-13 and the army.mil article do not state a rounding rule or a tape-reading increment, so this page compares the exact ratio with 0.55 and never rounds before deciding. Your unit's official measurement decides.
The calculator also shows 0.55 × your height, the largest waist that stays under 0.55, and how far your waist is from it. That is FedRateCalc arithmetic from the 0.55 rule. The height table lists it for 58 to 80 inches.
Worked example
A height of 70 inches and a waist of 36 inches give 36 ÷ 70 = 0.51428571, shown as 0.5143. That is under 0.55, so it meets the standard. At 70 inches, 0.55 × 70 = 38.5 inches, so this waist is 2.5 inches under it.
At the same height, a 38.5 inch waist gives exactly 0.5500 and does not meet the standard, because the directive's standard is "less than and not equal to 0.55". A 38.49 inch waist gives 0.54985714, shown as 0.5499, and meets it.
How the Army says the waist is measured
“The implementation of this assessment measures a Soldier's waistline at the navel (belly button) and divides that measurement by their height in inches, which produces the ratio for record.”
The directive and the article do not describe the tape position beyond that, and they give no increment for reading the tape. Your unit's official measurement decides.
If a ratio is 0.55 or greater
“If it is determined that the Soldier’s initial WHtR does not meet the standard, a confirmation measurement will be conducted on the same duty day by a team other than the one that took the initial set of measurements. This must occur before any actions are taken by the commander.”
“A Soldier with a WHtR of 0.55 or greater will be flagged and enrolled in the ABCP.”
“Units may initiate separation actions for a Soldier flagged due to failure of ABCP but no Soldier will be separated until an 180-day assessment is completed by HQDA and further guidance is disseminated.”
Army Directive 2026-13 also covers how often the ratio is measured:
“All Soldiers will have their WHtR measured at least twice per calendar year.”
The AFT and the waist-to-height ratio
“No AFT score exempts a Soldier from meeting the WHtR standard.”
“To ensure the WHtR does not interfere with Soldier performance on the Army Fitness Test (AFT) or Combat Field Test (CFT), commanders and supervisors will allow a minimum of 7 days between the AFT/CFT and WHtR. Commanders may deviate from this standard to meet urgent operational needs.”

Frequently asked questions
Does the Army still use the tape test?
Army Directive 2026-13 says: "No secondary or supplemental body composition methods (such as the circumference-based tape test or other body fat assessments) are authorized for the purpose of challenging the results of the WHtR." army.mil, July 7, 2026: "The Army has replaced the long-standing height and weight tables, circumference-based tape test, and supplemental body fat assessments with the waist-to-height ratio (WHtR) health assessment tool." The ABCP standard in the directive is the waist-to-height ratio, not a body fat percentage.
What is the Army waist-to-height standard?
Army Directive 2026-13 says: "The standard is a WHtR of less than and not equal to 0.55." At a height of 70 inches, 0.55 x 70 = 38.5, so a 38.5 inch waist is exactly 0.55 and does not meet the standard, while 38.49 inches is under it. That arithmetic is FedRateCalc's, not the directive's.
How is the Army WHtR measured?
army.mil says: "The implementation of this assessment measures a Soldier's waistline at the navel (belly button) and divides that measurement by their height in inches, which produces the ratio for record." Army Directive 2026-13 and the army.mil article do not state a rounding rule or a tape-reading increment, so this page compares the exact ratio with 0.55 and never rounds before deciding. Your unit's official measurement decides.
Does a high AFT score exempt you from the WHtR standard?
Army Directive 2026-13 says: "No AFT score exempts a Soldier from meeting the WHtR standard." It also says: "To ensure the WHtR does not interfere with Soldier performance on the Army Fitness Test (AFT) or Combat Field Test (CFT), commanders and supervisors will allow a minimum of 7 days between the AFT/CFT and WHtR. Commanders may deviate from this standard to meet urgent operational needs."
What happens if you do not meet the Army WHtR standard?
Army Directive 2026-13 says: "If it is determined that the Soldier’s initial WHtR does not meet the standard, a confirmation measurement will be conducted on the same duty day by a team other than the one that took the initial set of measurements. This must occur before any actions are taken by the commander." It also says: "A Soldier with a WHtR of 0.55 or greater will be flagged and enrolled in the ABCP." On separation, it says: "Units may initiate separation actions for a Soldier flagged due to failure of ABCP but no Soldier will be separated until an 180-day assessment is completed by HQDA and further guidance is disseminated."
How often does the Army measure the WHtR?
Army Directive 2026-13 says: "All Soldiers will have their WHtR measured at least twice per calendar year." It also says: "Commanders may, at any time, direct a Soldier to undergo a WHtR assessment if they are concerned that the Soldier does not meet the WHtR standard."
