“Globalization starts with getting the details right. Inconsistent use of SI units and international standard paper sizes is today the primary cause for U.S. businesses failing to meet the expectations of the global economy… In the ISO paper size system, all pages have a height-to-width ratio of square root of two (1:1.4142). This aspect ratio is especially convenient for a paper size. If you put two pages with this aspect ratio next to each other, or equivalently cut one parallel to its shorter side into two equal pieces, then the resulting page will have again the same width/height ratio.”
