The International Organization for Standardization (ISO) first introduced the A series of paper sizes in 1975. This system aimed to standardize paper sizes globally, making it easier for businesses to exchange documents and for individuals to use the same paper size for various purposes. A4 is part of the A series and has become the most commonly used paper size in the world.

How A4 Paper Got Its Dimensions

A4 paper is based on a mathematical formula devised by Georg Christoph Lichtenberg in the 18th century. The formula states that the ratio of the length of the longer side to the shorter side should be equal to the square root of two. When applied to paper sizes, this ratio creates a progressive increase in width and length as you go up the scale. For example, A3 paper is twice the size of A4, while A2 is twice the size of A3 and so on.
