The standard paper formats in most of the world come from the formats defined in 1922 in the DIN 476 standard. The sheet of manufactured paper measures one meter square and the measure of its sides keep a proportion that when divided in half, each of the halves keep the same relationship between their sides as the original sheet. The idea of this format is to try to make the most of the paper. In this way, when one size of paper is required, the manufacturer can cut without fear that the rest will be useless. In this article, we show you what the measurements are for the different paper formats.
