What changed in 2026: DoD body composition overhaul
On January 1, 2026, the Department of Defense replaced traditional height-and-weight tables
with Waist-to-Height Ratio (WHtR) as the primary body composition screening
method across all five U.S. military branches. The change was directed by a December 18, 2025
memorandum titled “Additional Guidance on Military Fitness Standards.”
The universal DoD standard is a WHtR of less than 0.55. To calculate it, simply divide your
waist circumference (in inches) by your height (in inches). A 5’10” person (70
inches) must keep their waist under 38.5 inches. For the Marine Corps, the standard is stricter
— under 0.52 per MARADMIN 066/26, meaning that same 70-inch person needs a waist under
36.4 inches.
Key change: Service members now undergo body composition assessments
twice per year, not once. Failing WHtR does not mean automatic failure — you
proceed to a body fat percentage calculation as a second step.
Army body fat tape test: how the formula works
When an Army soldier exceeds the WHtR 0.55 screening, they move to the one-site
abdominal circumference tape test under Army Directive 2023-11. This replaced the old
multi-site tape test that measured neck, waist, and hips for men.
The Army formula for males is: BF% = (86.010 × log10(waist − neck))
− (70.041 × log10(height)) + 36.76. For females: BF% = (163.205
× log10(waist + hip − neck)) − (97.684 × log10(height)) −
78.387. All measurements in inches.
A soldier who fails the tape test can request a supplemental body fat assessment using DXA
scanning, the InBody 770 bioelectrical impedance device, or the Bod Pod. Passing any
supplemental test overrides a failed tape result. Soldiers scoring 465 or higher on the AFT
with at least 80 points in every event are deemed in compliance with the body fat standard,
which exempts them from the tape assessment — not from the weigh-in. Height and weight
screening still happens and is still recorded on DA Form 5500 or DA Form 5501; what the
exemption removes is the circumference tape measurement for a soldier over the screening
weight. It runs until the next record test and no longer than 8 months for Regular Army and
AGR soldiers, or 12 months for National Guard and Army Reserve. Miss that window and the tape
assessment and flagging actions apply again. Score your AFT to see whether
that applies to you.
Navy Body Composition Assessment (BCA) 2026
The Navy updated its Physical Readiness Program guidance in December 2025 under OPNAVINST
6110.1L. The new BCA is a two-step process: Step 1 is the sex-neutral WHtR screen
(≤ 0.5499). Step 2 is a body fat percentage calculation for anyone over 0.55.
The Navy also added an absolute waist ceiling: men must be under 39 inches and women under
35.5 inches regardless of height. Maximum body fat is 26% for males and 36% for females. The
Navy body fat estimate uses waist, height, and weight measurements. The fitness half of the
Navy assessment is on the Navy PRT calculator.
Marine Corps standards: strictest in the DoD
The Marine Corps set a stricter WHtR standard of < 0.52 under MARADMIN
066/26. Marines who exceed 0.52 proceed to body fat testing using the multi-site tape method or
BIA (bioelectrical impedance analysis). Maximum allowable body fat is 18% for males and 26% for
females — the tightest limits in the DoD.
MARADMIN 066/26 also moved the Marine Corps to a sex-neutral PFT standard for combat arms
MOSs, requiring all Marines in those roles to meet the male scoring standard regardless of sex
beginning January 1, 2026. That change is scored on the
Marine PFT calculator.
Understanding VO2 max and military fitness
VO2 max measures how much oxygen your body can use during maximum effort exercise. It is
expressed in milliliters of oxygen per kilogram of body weight per minute (ml/kg/min). Higher
is better. The Cooper 12-minute run test — developed by Dr. Kenneth Cooper for the U.S.
Air Force in 1968 — is one of the most reliable field estimates and is still used by
military and law enforcement agencies worldwide.
For a 2-mile run, you can estimate VO2 max using validated military formulas. A soldier
running 14:30 has an estimated VO2 max of about 50 ml/kg/min. Running 16:00 puts you around 44
ml/kg/min. Elite special operations candidates typically need 55+. VO2 max naturally declines
about 1% per year after age 25, so the earlier you build it, the longer you retain it.

Body composition is only half the picture. Your actual test scores — deadlifts,
push-ups, sprint-drag-carry, plank, and 2-mile run — determine your Army AFT category.
Use the main military PT calculator to check your scores across all 5 branches
side by side with 2026 official standards, or read the
AFT standards and the
AFT scoring chart first.

Body composition and the fitness test are assessed separately, and only one of them has a

Frequently asked questions
What is the 2026 military waist-to-height ratio (WHtR) standard?
As of January 1, 2026, the DoD replaced height-and-weight tables with
WHtR as the primary body composition screen for all 5 branches. The universal standard is a
WHtR under 0.55 (waist circumference divided by height). The Marine Corps uses a stricter
0.52 standard per MARADMIN 066/26.

How is Army body fat percentage calculated in 2026?
The Army uses a one-site tape test measuring abdominal circumference at
the belly button, along with body weight, per Army Directive 2023-11. This replaced the old
multi-site neck/waist/hip method. Soldiers who fail the WHtR screen proceed to the tape test
as a second step.

What are the maximum body fat percentages for each military branch?
DoD sets a floor: males may not be required below 18% and females below
26%. Army maximums range 20–26% for males and 30–36% for females depending on
age. Marine Corps standards are the strictest. Branch-specific maximums are available in the
body fat calculator above.

Can a high AFT score exempt me from the body fat test?
From the tape test, yes — from the weigh-in, no. Under Army
Directive 2025-17, soldiers who score 465 or higher on the AFT with a minimum of 80 points on
every individual event are deemed in compliance with the Army body fat standard, and no
alternative events are permitted. You still complete height and weight screening and it is
still recorded on DA Form 5500 or DA Form 5501; what you skip is the circumference tape
assessment if you are over the screening weight. The exemption lasts until your next record
test and no longer than 8 months for Regular Army and AGR, or 12 months for National Guard
and Army Reserve — fail to re-validate inside that window and you are subject to the
body fat assessment and to flagging again.

What is a good VO2 max for military service?
For military service, men should target a VO2 max of 45+ ml/kg/min and
women 38+ ml/kg/min to be competitive on fitness tests. Elite combat units typically require
50+ for males. VO2 max can be estimated from your 2-mile run time using the calculator
above.
This is a training benchmark, not a service standard. No U.S. service records a VO2 max score. · Verified 27 JUL 2026
