Marine Corps waist-to-height ratio calculator
Check whether your waist size meets the Marine Corps standard for your height. This Marine Corps waist-to-height ratio calculator shows your ratio, the maximum waist size for your height, and what your result means.
Enter your height and two waist measurements in inches or centimeters. The calculator takes care of the rounding and uses the lower waist reading, so you don’t need to work out the numbers yourself.
A ratio of 0.52 or lower meets the waist-to-height standard. A higher result means a follow-up body-fat check is needed; it does not automatically place you in the Body Composition Program.
How to check your Marine Corps waist-to-height ratio
- Choose inches or centimeters.
- Enter your height.
- Enter two waist measurements taken at your belly button (navel).
- Select Calculate to see whether your measurements meet the standard and the maximum waist size for your height.
Want to try it first? Select Use example, then replace those values with your own measurements. For an official assessment, use the measurements taken by your evaluator.
How to take and enter your measurements
Follow the current Marine Corps evaluation procedure and your evaluator’s instructions. Place the tape at your belly button (navel), keep it level all the way around, and hold it snug against your body without pressing into the skin. Take and enter both waist readings.
If you enter centimeters, the calculator converts them to inches first. It then rounds height and each waist reading down to the next half inch. For example, 70.8 inches is recorded as 70.5 inches. The lower of your two recorded waist readings is used, and the official height table covers 53 through 84 inches.
What does your waist-to-height ratio mean?
Your waist-to-height ratio (WHtR) compares your waist size with your height: divide waist by height, using the same units. For the Marine Corps check, the calculator first rounds the measurements down to the nearest half inch and uses the lower waist reading.
0.52 or lower meets the standard. The rule is the same for men and women. A higher result means you need a follow-up body-fat check. You’ll also see your maximum waist size, which makes the result easier to put into context.
A quick waist-to-height ratio example
| Recorded height | Recorded waist | Waist-to-height ratio | What it means |
|---|---|---|---|
| 70 in | 36 in | 0.5143 | Meets the standard |
| 75 in | 39 in | 0.5200 | Meets the standard at the limit |
| 70 in | 36.5 in | 0.5214 | Follow-up body-fat check |
At 75 inches and 39 inches, the ratio is exactly 0.5200, so it passes. At 70 inches and 36.5 inches, the ratio is 0.5214, so a follow-up body-fat check is needed.
What is the maximum waist size for your height?
Find your height below to see the largest waist measurement that meets the Marine Corps standard. The official table covers heights from 53 to 84 inches in half-inch steps. Use your measurements after rounding down, as shown in your calculator result.

What happens next and official Marine Corps sources
If your ratio is above 0.52, your next step is a body-fat evaluation through your command. This calculator cannot tell you your body-fat percentage or replace that official assessment. High fitness-test scores can affect your body-fat allowance, but they do not remove the waist-to-height check.
For the full policy, read MARADMIN 066/26, MARADMIN 073/26, MCBul 6110 W/Admin CH-1, MARADMIN 358/26, and the Human Performance Branch standards page.

Marine Corps waist-to-height ratio FAQs
Does a ratio of exactly 0.52 pass?
Yes. A ratio of exactly 0.52 meets the current Marine Corps standard for both men and women. MARADMIN 073/26 confirms that 0.52 is included.
How should I measure my waist?
Place the tape at your belly button (navel), keep it level, and hold it snug without pressing into your skin. Follow your evaluator’s instructions and enter both waist readings.
Why does the calculator ask for two waist readings?
The calculator rounds each reading down to the next half inch, then uses the lower recorded waist. Enter both readings so it can follow that process.
What if my ratio is higher than 0.52?
A higher result means you should follow up with a body-fat check. It does not automatically place you in the Body Composition Program.
Can my PFT or CFT score waive this check?
No. Physical Fitness Test (PFT) and Combat Fitness Test (CFT) scores can affect the body-fat limit that applies after a higher waist-to-height result, but they do not remove the waist check.
