About this result
Army Directive 2026-13. Enter already recorded height and average waist measurements from the prescribed procedure. The final ratio truncates to three decimals; it does not round to nearest.
This arithmetic estimate is not an official assessment. Confirmation measurements, exemptions and personnel decisions are outside its scope. WHtR is a ratio, not a body-fat percentage.
How it works
Equal ratios, different measurements
A recorded waist of 32 inches at 64 inches tall and 35 inches at 70 inches tall both give 0.500. The ratio compares proportions; it does not mean the two people have identical body composition.
Selecting the correct Army assessment method
This calculator separates the stated current waist-to-height method from the historical one-site estimate. Select the mode that matches the policy and purpose you are checking before entering measurements. Historical and current outputs should not be compared as if they were the same assessment. Read the source and applicability notes; the calculator does not issue an official fitness or administrative determination.
2026 Army waist-to-height ratio: formula and assumptions
Recorded ratio = truncate(average waist / height, 3 decimals).
Uses recorded measurements under Army Directive 2026-13. A ratio below 0.550 meets the stated numerical threshold. It does not replace the official measurement or confirmation procedure.
Historical 2023 one-site estimate: formula and assumptions
Male: −26.97 − 0.12 × weight(lb) + 1.99 × abdomen(in). Female: −9.15 − 0.015 × weight(lb) + 1.27 × abdomen(in).
Historical 2023 equation, superseded for Army assessment by the 2026 waist-to-height policy. It estimates body-fat percentage and does not determine current compliance.
Worked example
Using the 2026 Army waist-to-height ratio example:
- Recorded height (in)
- 70
- Recorded average waist (in)
- 35
Recorded ratio = truncate(average waist / height, 3 decimals).
Example result
Recorded waist-to-height ratio: 0.500
Untruncated ratio: 0.5
2026 stated threshold: Below 0.550
- Army Directive 2026-13. Enter already recorded height and average waist measurements from the prescribed procedure. The final ratio truncates to three decimals; it does not round to nearest.
- This arithmetic estimate is not an official assessment. Confirmation measurements, exemptions and personnel decisions are outside its scope. WHtR is a ratio, not a body-fat percentage.
These are illustrative inputs. Change the values to explore a different scenario.
What to keep in mind
The current 2026 mode uses recorded waist-to-height measurements. The 2023 body-fat equation is retained as a historical estimate. Neither output certifies military eligibility.

Common questions
Is waist-to-height ratio a body-fat percentage?
No. The ratio divides recorded waist circumference by recorded height. The 2026 Army method truncates it to three decimals and compares it with 0.550. The older one-site equation estimates body-fat percentage and is shown separately as historical.
Does this result count as an official assessment?
No. It calculates from your recorded inputs. Official measurement, confirmation, exemption and administrative procedures require the applicable Army guidance.
