I was watching a youtube video from Mystic on how to measure stamps for mounts.
The statement goes -
"Mounts are measured in millimeters. If you are not familiar with the metric system, a millimeter is a tenth of a centimeter"
Duh!
Now they do overlay a millimeter scale to an inch scale but the comment should have been like there are 25.4 millimeters per inch.
I know it is early but the video just seems inaccurate. It should simply say measure the stamp and then get one with that height (or add a mmm or two for thicker or self-adhesives). They discuss adding 5mm to all stamps height and referring to the overall mount size (not the pocket for the stamp itself).
There's an easier way, 1 mm is a bit bigger than 1/32, so if you me sure your stamps in 32 nds of an inch you'll already have the added room for the stamp, naturally the smaller the stamp the tighter the fit but since we are talking stamps, not astronomically speaking dimensions, you'll have a perfect fit.
...or you can view/print out the free Scott Mount Sizing Guide, put your stamp over the outlines, find the best fit (don't go small as too small a mount will warp the stamp) and you'll know what size mount to use.
I cut this one out of the back of a Kenmore catalog and laminated it. Makes a useful tool when determining mount sizes, or even sizing frames when creating custom pages.
