I am working toward an installation of about a dozen photographs, 20"x30" each. With mats, the whole assembly will measure 32"x40". So, I ordered frames 32"x40". They came with foam cores and acrylic glazing. Each piece measured exactly 32"x40". The acrylic and foam core fits snugly into the frame, of course. Delightful!
I also ordered mat board in size 32"x40". Unfortunately, the actual size turns out to be 30.05"x40.125". In order to fit the mats into the frames, I have to try to force them in, potentially damaging the frames or the mats, or both. I can live with the extra 3/64" on the short side, but the extra 1/8" on the long side is driving me nuts. I find myself trimming off the extra 1/8". With my modest tools and even more modest skills, this usually means expending a considerable amount of energy and producing a ragged edge.
Why do companies (the mats come from a very reputable company) insist on giving us such a "bonus?" I understand that 2" x 4" lumber isn't really 2" x 4', but I believe there's some rationale for that. (I've probably heard the story, but it doesn't stick with me.) Everyone accepts that and has learned to live with it. But why is 32" x 40" actually 30.05" x 40.125"?
I often buy my foam cores separately from my frames. I buy them 32" x 40" (nominal), since I can get a half dozen 11" x 14" cores from one sheet more inexpensively than purchasing six individual foam cores pre-cut to 11" x 14". I've noticed a discrepancy before, but attributed it to my lazy measuring habits. Besides there's scrap on both sides, so it never really mattered.
Why is this?

The reason is because, in most of the world they do everything in metric and their products in the US are stated as close as they can in inches.
