Army Height and Weight Calculator

It is a two-step process, and this is the part most people misunderstand. First comes the screening weight table: if your weight falls at or below the maximum screening weight listed for your height, age and sex, you are compliant and nothing further is required. Only if you exceed that screening weight does the second step apply — a body fat assessment using the circumference tape method. Exceeding the screening weight is therefore not itself a failure. Muscular soldiers routinely exceed it and then pass comfortably on body fat, because the screening table cannot distinguish muscle from fat any better than BMI can. The body fat standard is the actual determinant of compliance.

Under AR 600-9, the limits rise with age, reflecting the natural increase in body fat across adulthood. For men the maximums are 20% for ages 17–20, 22% for 21–27, 24% for 28–39, and 26% for 40 and over. For women they are 30% for ages 17–20, 32% for 21–27, 34% for 28–39, and 36% for 40 and over. The higher female figures reflect essential fat requirements — women carry substantially more essential fat than men for normal physiological function, so applying male standards to women would be both unfair and medically inappropriate. Always confirm the current figures against the latest published regulation, since standards are periodically revised.

The Army circumference method measures the abdomen for men, and the waist and neck for women, alongside height. Measurements are taken directly against the skin, with the tape snug but not compressing tissue, and are read at the end of a normal exhale. For men, the abdominal measurement is taken at the navel. For women, the waist is measured at the narrowest point of the torso. Neck circumference is measured just below the larynx. Each measurement is taken three times and averaged, and readings are recorded to the nearest half inch or centimetre depending on the recording standard in use. Consistency in landmark placement matters enormously — a centimetre of difference in where the tape sits can shift the resulting body fat figure by more than a percentage point.

Because the screening weight table is based on height alone and, like BMI, has no way to distinguish lean mass from fat mass. A soldier who has spent years building muscle can easily weigh 10–15 kg above the screening threshold for their height while carrying well below the permitted body fat percentage. This is precisely why the regulation includes the tape test as a second step rather than treating the weight table as the final word. If you exceed the screening weight, the tape assessment is your route to demonstrating compliance — and for a genuinely muscular soldier, it usually confirms it comfortably.

The circumference method carries a typical error margin of roughly 3–4 percentage points against laboratory reference methods such as DEXA or hydrostatic weighing. It systematically overestimates body fat in some very muscular individuals with thick waists relative to their frame, and can underestimate in others carrying visceral rather than subcutaneous fat. This is a known and accepted trade-off: the method requires only a tape measure, takes minutes, and can be administered consistently across hundreds of thousands of personnel, which no laboratory method could achieve at that scale. For personal tracking, its stability day-to-day is arguably a strength, since circumferences change more slowly and predictably than impedance-based readings.

No. Each branch maintains its own regulation with different screening weight tables, different body fat limits, and in some cases different measurement protocols. The Marine Corps generally applies stricter body fat maximums than the Army, and the Navy uses a slightly different circumference formula. This calculator implements the Army standards under AR 600-9 specifically. If you serve in another branch, use your own branch's current regulation — applying Army figures to a Marine Corps assessment will give you a misleading result.

Yes, as a preparation and tracking tool — but not as a substitute for the official assessment. Your unit's measurement will be taken by trained personnel following the exact protocol in the current regulation, and small differences in tape placement, timing, hydration and even time of day can shift the result. Use this calculator to understand roughly where you stand, to track progress over weeks, and to know whether you are likely to need the tape test at all. If you are close to a limit, give yourself margin rather than relying on being exactly at the line, since measurement variation alone can push a borderline result either way.
