Military Surplus Sizing Guide
Due to the wide variety of surplus clothing we carry, a standardized sizing guide helps customers find the best fit. However, military surplus can vary significantly in fit and cut. This chart serves as a general reference rather than an exact, tailor-level measurement.
Each military has its own sizing system, which is why we’ve created this guide to help you understand how we size our surplus garments.
Jacket & Shirt Sizing
When an official military size chart is unavailable, we measure each jacket or shirt from armpit to armpit (PtP) to estimate its fit. If a measurement falls between sizes, we round it down. For example, a shirt with a 19.75" PtP is categorized as a Small rather than a Medium.
Sizing Chart (Armpit-to-Armpit Measurement)
- 14"-15" PtP = XXS
- 16"-17" PtP = XS
- 18"-19" PtP = Small
- 20"-21" PtP = Medium
- 22"-23" PtP = Large
- 24"-25" PtP = XL
- 26"-27" PtP = XXL
- 28"-29" PtP = 3XL
Pant Sizing
We convert military pants to standard U.S. waist and inseam sizes. If a pair measures between sizes, we round down. For example, a 33" waist is listed as a 32" waist.
How We Measure Pants:
- Waist: Pants are laid flat, and we measure straight across the waistband. This number is doubled to determine the U.S. waist size. (Example: A 16" flat waist measurement equates to a U.S. 32" waist.)
- Inseam: We measure from the crotch seam to the bottom of the cuff. (Example: A measurement of 30" from crotch to cuff is listed as a 30" inseam or 30L.)
