Sizing a belt for inside-the-waistband carry

A holster inside the waistband takes up room between you and your trousers, so the belt has to go around more. That is why inside-the-waistband carry, including appendix and small of back, means one size up, on The Marshal and The Sentinel alike. Outside the waistband, or without a holster, there is no need to size up.
Start with your pant size
Use the waist number on the tag of the trousers you wear. If you are buying for someone else, check the size on their pants.
The Marshal
- Take your pant size and subtract 2. Pant 36 is size 34.
- Carrying inside the waistband? Size up one size: add 2.
- If you land on an odd number, round up to the next even size. The nine holes, 1 in apart, leave room to tighten, but a belt that is too short can't be fixed.
The Marshal comes in sizes 32 to 44. Each belt measures 11 in more than its size from the buckle to the tip (size 34 is 45 in), and the holes start 4 in from the tip.
The Sentinel
- Choose the range that holds your pant size: Small is pant 28 to 32, Medium is 32 to 36, Large is 36 to 40, and X-Large is 40 to 44.
- On an edge (32, 36 or 40), choose the larger size. The ratchet's 1/4 in steps take up the difference.
- Carrying inside the waistband? Start from the smaller size whose range holds your pant size (on an edge, that is the smaller of the two), then size up one: Small to Medium, Medium to Large, Large to X-Large. Pant 32 is Medium, 36 is Large and 40 is X-Large. X-Large is the largest size, so it has no size up: if you wear X-Large, The Sentinel doesn't come in your size for inside-the-waistband carry.
Let the fit finder check it
The fit finder applies these rules for both belts and tells you if a size isn't available right now. Not sure? Exchanges are easy, and you have 30 days.
