Mystic Has High Quality Stamp Mounts For Every US Stamp!

Mystic sells pre-cut mounts for every US postage stamp. That’s 407 different sizes of pre-cut mounts that make it extra easy for you to collect. Like many collectors, I have a hard time cutting mounts straight. Now you don’t have to cut mounts for US postage stamps, and many foreign stamps too. Mystic’s pre-cut stamp mounts save you lots of time and effort.

How to Find the Right Mount Size for Your Stamp

Stamp mounts are sold according to size in millimeters. The first number is the horizontal measurement, or width, across the mount. The second number is the vertical measurement, or height, of the mount. Example: A 45 x 30 mount measures 45 mm wide by 30 mm high.

Mystic Stamp Company Stamp Mounts Sizing Guide

If you don’t know the Scott number, you may enter the measurement of your stamp in millimeters – width first, then height. If your stamp falls between two sizes, select the larger mount. Sizes for water-activated stamps are generally 5 mm larger than the stamp in both directions. See how to measure your stamps at

Please Note: The mount size for self-adhesive stamps is generally 6-7mm larger in each direction because their backing makes them thicker.

Once you have your mounts, you’ll need to insert your stamps. Click here to learn how to use stamp mounts and hinges.
