Sure, I knew that American systems of measurement sucked. But I didn’t know that our standard paper size sucked until I met A4 almost a year ago.
How is it superior? The ratio of its length to its width is the square root of 2. If you cut this magical paper in half, the resulting size is called A5 and has the same ratio. Do it again and you have A6–same ratio.
Suffice it to say that I loathe the idea of ever going back to US Letter.
