What is "A" Series Formats

A4 is the paper size defined by the ISO 216 standard and is based on the metric system. Its dimensions are 210 × 297 mm, the diagonal is 364 mm. Area of A4 sheet = 1/16 m².

A4 sheet was obtained by sequentially dividing in half a sheet of A0 format, which has an area of exactly 1 m²: A0: 2 = A1, A1: 2 = A2, A2: 2 = A3, A3: 2 = A4. In turn, when dividing an A4 sheet in half, you get two sheets of A5 format, while observing the semblance of a formal sheet and its half, the aspect ratio is 1: √2 (Lichtenberg ratio). Numerically, the dimensions 297 mm and 210 mm are multiples of the numerator and denominator of the rational approximation to the value √2: 99/70 ≈ 1.4142857. The error does not exceed 1/10000, despite the small denominator.

A4 format is very widely used for documentation, drawings, letters, magazines, letterheads, consumables for printers and copiers.

At the beginning of the twentieth century, there were no uniform sizes for business papers and design documentation in Europe at all. Each paper mill produced its own sheet size.

The proportions of the rectangular sheet were also chosen differently. The "golden ratio" 1: 1.618, which the architects and painters of the Renaissance loved so much, turned out to be completely unsuitable for printing and publishing. When folding such a sheet in half, the proportions of the resulting page changed and became inconvenient for work.

Other proportions turned out to be more suitable for practical needs: a leaf, the sides of which belonged as a unit to the square root of two, when folded in half, gave a rectangle with the same ratio. In other words, it was similar to the original one.

Dr. Walter Porstmann, a German engineer, mathematician and theorist of standardization in industry, one of the founders of the German DIN system, proposed to standardize paper sizes based on a sheet with an aspect ratio of 1: 1.4143 and an area of one square meter.

The draft of the German Manufacturing Standards Committee was published on August 18, 1922. The original format was designated A0. The results of folding it in half are A1, A2, and so on, respectively. Thus, A4 size is 1/16 of a large A0 sheet.
