What This Body Metrics Tracker Does
This free printable tracker turns the math you already know into a weekly habit. Enter your height, current waist, and weight, pick a 4-, 8-, or 12-week period, and you get a US Letter worksheet with one row per week. Each row logs date, weight, waist, waist-to-height ratio (WHtR), a pass ✓ against the 2026 military screen, and your notes. The baseline row is pre-filled with your starting values, and WHtR plus the pass/fail flag update live as you type.
The WHtR reference used here is the real 2026 Department of Defense standard: a waist-to-height ratio below 0.55 passes the initial body-composition screen, uniform across age and sex. BodyStd has the full breakdown on our military body composition standards page, and you can check your own numbers instantly with the military body composition calculator.
2026 WHtR Screen — Reference Table
As of January 1, 2026, the DoD uses waist-to-height ratio instead of the old height-and-weight tables for the initial body-composition screen. You pass the screen when your WHtR is below the threshold for your branch:
| Branch | WHtR Pass Threshold | First-Line Screen? | Governing Instruction |
|---|---|---|---|
| Army | < 0.55 | Yes | Army Directive 2026-13 / AR 600-9 |
| Navy | < 0.55 | Follow-up | MyNavyHR Guide-4 (Body Composition Assessment) |
| Air Force | < 0.55 | Follow-up | DoDI 1308.03 / Air Force Physical Requirements |
| Marine Corps | < 0.52 | Yes | MARADMIN 066/26 / MCO 6110.3 |
| Coast Guard | < 0.55 | Follow-up | Coast Guard Body Composition Standards Program |
Max waist that still passes at WHtR 0.55
| Height | Height (in) | Max waist below 0.55 |
|---|---|---|
| 5 ft 4 in | 64 | 35.2 in |
| 5 ft 6 in | 66 | 36.3 in |
| 5 ft 8 in | 68 | 37.4 in |
| 5 ft 10 in | 70 | 38.5 in |
| 6 ft 0 in | 72 | 39.6 in |
| 6 ft 2 in | 74 | 40.7 in |
Formula: waist ÷ height < 0.55, so max waist = 0.55 × height. Values verified August 11, 2026 against the published DoD / Army standard.
Old Body-Fat Percentages Are Gone
The old maximum body-fat percentage tables (roughly 20–26% for men and 30–36% for women by age) are now historical references only — the 2026 screen is WHtR first. High fitness scores can still earn exemptions: for example, an Army Combat Fitness Test score of 465 or higher (per Army Directive 2025-17) can exempt a soldier from the tape-test follow-up. For the full picture, see our 2026 standards guide.
Why Track Waist and WHtR Instead of Just Weight
Weight alone can stay flat while your body composition changes, and it cannot tell you where fat is stored. Waist circumference tracks abdominal fat — the pattern most strongly linked to cardiometabolic risk — and WHtR normalizes that number for height. Combining a weekly waist log with an optional BMI gives you two independent signals on one sheet of paper. Learn more in our waist-to-height ratio calculator and BMI calculator.
Frequently Asked Questions
What is the waist-to-height ratio (WHtR)?
Waist-to-height ratio (WHtR) is your waist circumference divided by your height, measured in the same units. It is a simple screening metric for abdominal obesity. A WHtR below 0.5 is generally considered healthy, and below 0.55 is the 2026 DoD and Army body-composition screen threshold.
What does the 0.55 WHtR threshold mean?
Effective January 1, 2026, the Department of Defense replaced height-and-weight tables with a waist-to-height ratio screen. Under the DoD-wide and Army standard (Army Directive 2026-13), you pass the initial screen when WHtR is below 0.55 — the same threshold for all ages and sexes. For example, at 5 feet 10 inches tall, 0.55 x 70 inches = 38.5, so your waist must stay under about 38.5 inches to pass.
How do I measure my waist correctly?
Stand relaxed, exhale gently, and wrap a flexible tape measure around your bare abdomen at the level of the navel — not at the narrowest point. Keep the tape snug but not compressing the skin, parallel to the floor, and read the measurement. Measure at the same time of day and in the same spot each week so your tracker shows real trends.
How is WHtR different from BMI?
BMI compares total weight to height and does not distinguish muscle from fat or show where fat is stored. WHtR uses waist circumference directly, so it better reflects abdominal (central) fat, which carries higher cardiometabolic risk. This tracker logs both: WHtR is the primary benchmark, and BMI is shown as an optional secondary metric.
How often should I measure and track?
Once a week is the sweet spot for trend tracking. Measure your waist and weight on the same day and roughly the same time each week, such as every Monday morning. Daily weighing is noisy because of water and food fluctuations, while measuring less than weekly makes it hard to spot a real trend before the habit drifts.
