Army Body Fat Standards (AR 600-9): Complete 2026 Guide

The baseline regulation is AR 600-9, "The Army Body Composition Program," dated 16 July 2019. AR 600-9 itself is still active, but the formulas, age brackets, and measurement protocol it implements have been overwritten by a series of ALARACT messages. The current implementing policy is ALARACT 087/2025, "Notification of Army Body Fat Standard Modifications for the Army Body Composition Program," published 10 September 2025.

ALARACT 087/2025 is the third message in a chain. ALARACT 046/2023 (12 June 2023) was the actual break with the past — it introduced the one-site abdominal tape method and the current Table B-2 age brackets. ALARACT 032/2025 reissued the same guidance in March 2025, and ALARACT 087/2025 brought the policy forward through September 2026 with one substantive tweak: replacing the old ACFT 540-point body-fat exemption with a 465-point AFT exemption tied to the new Army Fitness Test.

Why simplify? The Army's stated rationale, captured in Army Directive 2023-11 and the ALARACT 046/2023 transmittal, was that a single-site abdominal measurement combined with body weight is a better statistical predictor of total body fat for the modern soldier population than the older multi-site approach, while also being faster, easier to standardize, and less prone to measurement error in the field. Multi-site protocols depend on getting every tape placement correct; collapsing the test to one circumference plus a scale weight removes most of the failure modes.

You can read the current regulation directly on Army Publishing Directorate at armypubs.army.mil (ARN44894). Attachment 1, Table B-5 contains the formulas; Table B-2 contains the age-based maximums.

The transition also retired the Hodgdon-Beckett-style multi-site equation that the Army had used for years. Hodgdon-Beckett is a DoD-prescribed circumference method built around logarithms of neck and waist (and, for women, hip) circumferences along with height. The Navy and Marine Corps still use it. The Army no longer does. If you took an Army tape test before June 2023, the measurer wrote down a neck reading and an abdomen reading and fed them through that older equation. After June 2023, the neck measurement is no longer collected at all for body composition purposes — only the abdomen and the soldier's body weight from a calibrated scale.

One thing the 2023 change did not do: it did not adopt a waist-to-height ratio test. Several SEO-bait articles published in early 2026 claim the Army switched to a 0.55 waist-to-height standard. That is incorrect. ALARACT 087/2025 preserves the one-site abdominal circumference formula in force since 2023. The Marine Corps did add a waist-to-height first screen in 2026 (MARADMIN 066/26, ratio ≤ 0.52), and that USMC change is what some of those articles appear to have confused with Army policy. They are different services with different programs.

Under the current Army standard, body fat percentage is computed from exactly two inputs: the soldier's body weight in pounds and the abdominal circumference in inches. There is no neck measurement, no hip measurement, no height term. The formulas come from ALARACT 087/2025 Attachment 1, Table B-5, and the result is rounded to the nearest whole percent.

A natural question: how can a formula with only two variables be accurate? The answer is that this is not a biological model. It is a regression equation derived from a study population whose true body composition was measured by reference methods such as DEXA. Statisticians fit a line through the cloud of measurements, keeping the variables that explained the most variance. For the Army's reference population, abdominal circumference and body weight together capture enough of the signal to make a third or fourth input unhelpful. Adding more sites would marginally improve accuracy at significant cost in measurement variability — the opposite of what the Army wanted.

Notice the male formula weighs the abdomen term much more heavily than the female formula (1.99 vs 1.27) and treats body weight more aggressively (−0.12 vs −0.015). That asymmetry reflects the different body fat distribution patterns the regression had to model. It also explains why a male and a female with identical weight and waist size will get very different percentages.

DEXA, BIA (the InBody 770 in particular), and BOD POD are authorized under ALARACT 087/2025 only as supplemental assessments after a failed tape test. The tape result is the primary determination — the higher-tech methods only enter the picture if a soldier wants a second opinion after failing.

The single-site test only works if the single site is taken correctly. ALARACT 087/2025 sections B-2 through B-5 lay out the protocol in detail. The most important rules:

• Uniform: Army PT shorts and T-shirt, stocking feet. No girdles, compression garments, or shapewear.
• Tape: Non-stretch fiberglass tape, ¼ to ½ inch wide. A trained measurer takes the reading; a recorder/witness writes it down. Cloth tailor's tape is not authorized.
• Site: The abdominal circumference is taken at the navel. Not at the natural waist, not at the iliac crest, not at the smallest point of the torso. The navel is the landmark, period.
• Posture: Soldier stands relaxed with arms at the sides and feet together. Not flexed. Not sucked in. The measurement is taken at the end of a normal exhalation — not after a forced exhalation and not while holding the breath.
• Tape position: The tape is held parallel to the floor, against the skin (not over clothing), snug but not compressing the soft tissue.
• Three readings: Take three measurements. If the three closest readings agree within one inch of each other, average them. If not, take additional measurements. The final value is rounded down to the nearest half inch.
• Body weight: Recorded on an official calibrated scale, in the same uniform as the tape test, to the nearest pound.
• Edge cases: If the umbilicus is obscured (for example by scar tissue), the measurer marks the approximate location with a sharpie before taping. If there is no umbilicus at all, the mark goes two inches above the anterior superior iliac spine.

The "exhale normally, do not flex, do not suck in" rule matters more than most soldiers realize. Sucking in shrinks the measurement — and because the male formula multiplies the abdomen term by 1.99, every inch you erase takes nearly two percentage points off your result. That sounds like an advantage until you remember that the measurer is supposed to catch it, flag it, and either retake or report. Honest measurement is the only sustainable path.

Maximum allowable body fat percentages come from ALARACT 087/2025 Attachment 1, Table B-2. The brackets differ between male and female soldiers and step up at different ages than the Navy or Marine Corps schedules. The "40 and older" bracket has no upper age bound in the regulation.

A 19-year-old male soldier needs to be at or below 20% body fat; two years later the standard relaxes by two points. Female standards run ten percentage points higher across every bracket, reflecting the larger essential-fat baseline that women carry. The brackets do not interpolate — the day a soldier turns 21, the male maximum jumps from 20% to 22%.

The Army's bracket structure is worth comparing against the other services. The Navy uses brackets at 17–21, 22–29, 30–39, and 40+, starting at 22% for males rather than 20%. The Marine Corps uses 17–25, 26–35, 36–45, and 46+ and starts even lower at 18% for males. So the Army is stricter than the Navy at the youngest ages (20% vs 22%), looser than the Marine Corps across the board (the USMC ceiling at age 46+ is 21%, well under the Army's 26% ceiling), and uses age cuts that don't line up with either neighbor. There is no DoD-wide harmonization here — each service publishes its own table on its own schedule.

The female Army brackets follow the same shape as the male ones but with a flat ten-point offset at every age. That offset is a regulatory choice rather than a derivation from the formula coefficients themselves. The formulas produce raw percentages; the Table B-2 numbers are the policy thresholds those raw percentages get compared against.

A common misconception is that the body fat test is part of the Army Combat Fitness Test (now transitioning to the Army Fitness Test). It is not. The Army Body Composition Program and the ACFT are governed by separate regulations, scored separately, and enforced separately. A soldier can max the ACFT and still fail the tape test, and a soldier can pass the tape test and still fail the ACFT. The two programs are independent.

The reason this confuses people is that the ACFT and ABCP both measure something the Army calls "fitness" in plain English. But they measure different things: the ACFT measures performance across six events, while ABCP measures body composition against age- and sex-normed thresholds. The Army keeps them separate because each catches problems the other misses. A soldier who passes the ACFT through pure power but carries excess subcutaneous fat is still flagged by ABCP, and a lean soldier who can't run a 2-mile event is still flagged by the ACFT.

ALARACT 087/2025 does provide one bridge between the two programs: a soldier scoring 465 or higher on the Army Fitness Test (with a minimum of 80 points in each event) is deemed body composition compliant regardless of the tape test result. This replaces the older ACFT 540-point exemption. The exemption only applies to soldiers who actually meet the score threshold — everyone else is held to the Table B-2 numbers.

The performance exemption deserves a closer look, because it is the part of the policy soldiers most often misunderstand. Hitting 465 on the AFT is not trivial — it requires consistently strong performance across every event, not just stacking points in one or two. The "80 in each event" floor is what prevents a soldier from gaming the exemption with a single dominant event score. In practice the exemption rewards soldiers who are objectively performing at a high level, on the theory that someone capable of that AFT score is functionally fit regardless of what the tape says. It is not a loophole; it is an alternative pathway to compliance.

For soldiers below the exemption threshold, the tape test is the determination. There is no partial credit, no curve, and no appeal based on muscle mass — if you measure over your bracket maximum, you are over. The Army acknowledges that the formula can mislabel highly muscular soldiers as over-fat, which is part of why the AFT exemption exists in the first place.

Failing the tape test is not a one-day event. It triggers entry into the Army Body Composition Program, a structured timeline intended to give the soldier a real chance to come back into standard before any administrative action is considered.

In broad terms, the process begins with an initial screening flag that restricts certain favorable personnel actions — promotions, awards, attendance at professional development schools — while the soldier is enrolled. The soldier is given a window of several months to lose body fat at a sustainable rate. During that window the soldier is reassessed periodically, typically monthly, and is expected to show measurable progress at each checkpoint.

The Army's expected weight loss rate is conservative — roughly one to two percent of body weight per week is the commonly accepted ceiling for healthy fat loss. Progress that beats this is welcome, but the program is structured around the conservative number to avoid pushing soldiers into crash dieting. Nutrition counseling and command-supported PT are part of the program.

A soldier who reaches standard during the program is removed from ABCP enrollment and the flag is lifted. A soldier who fails to make satisfactory progress, or who enters and exits ABCP repeatedly, is at risk of administrative separation under AR 600-9 procedures. The separation pathway is not automatic and not immediate — it requires command action and is documented through the soldier's chain of command, not by the program itself. Soldiers who feel they are being processed unfairly should consult their unit's legal assistance office rather than rely on barracks rumor about specific timelines or paperwork.

One important nuance: medical conditions that affect body composition (thyroid disorders, certain medications, post-pregnancy recovery) can be grounds for temporary exemption if documented through proper medical channels. The program contemplates these cases — soldiers in this situation should work with their PCM and chain of command early rather than waiting until after a failed tape.

The cultural shift the 2023 change brought is also worth flagging. Under the old multi-site method, the result felt opaque to many soldiers — neck and waist numbers fed into a logarithmic formula whose output was hard to predict from the inputs. The new one-site method is much easier to mental-math. Add an inch to your abdomen reading and a male soldier's predicted body fat goes up by almost exactly two percentage points; lose five pounds and it drops by 0.6 points. Soldiers can now look at the formula, look at their own numbers, and form a clear picture of what would have to change to come into standard. That transparency was an explicit goal of the 2023 revision.

To check your numbers against the current Army standard, use the dedicated Army body fat calculator. It implements the ALARACT 087/2025 one-site abdominal formula exactly as published — no rounding shortcuts, no smoothed age curves, no shortcuts on the Table B-2 thresholds. Enter your age, sex, body weight in pounds, and abdominal circumference at the navel. The result tells you both your computed body fat percentage and whether it falls inside your age bracket's maximum.

The calculator is the right tool for spot checks before a weigh-in, for tracking progress while enrolled in ABCP, or for recruits who want to know what they need to look like before they ship. It is not a substitute for the official tape test — your unit's measurer is the only authority for your record — but the math is identical.
