Comparison of some paper and photographic paper sizes close to the A4 size. Many size standards conventions have existed at different times and in different countries.

Today, the A and B series of, which includes the commonly used A4 size, are the international standard used by almost every country. However, in many countries in as well as in the, the North American series of paper sizes such as ' is more prevalent. Paper sizes affect writing paper,, cards, and some printed documents. The international standard for envelopes is the C series of. • Spain (1947) • Austria (1948) • (1948) • (1949) • Japan (1951) • Denmark (1953) • (now and ) (1953) • Israel (1954) • (1954) • (now,,,,, and ) (1956) • India (1957) • (1957) • United Kingdom (1959) • (1959) • (1962) • New Zealand (1963) • (1964) • Mexico (1965) • (1966) • France (1967) • (1967) • (1967) • (1968) • Greece (1970) • (now ) (1970) • (1970) • (1972) • (1973) • (1973) • Australia (1974) • (1974) • (1975) • (1975) By 1975, so many countries were using the German system that it was established as an standard, as well as the official document format. By 1977, A4 was the standard letter format in 88 of 148 countries.

Today the standard has been adopted by all countries in the world except the United States and Canada. In Mexico,,,,, and the, the format is still in common use, despite their official adoption of the ISO standard. B series [ ]. A size chart illustrating the ISO B series. In addition to the A series, there is a less common B series.

The area of B series sheets is the of successive A series sheets. So, B1 is between A0 and A1 in size, with an area of 0.707 m 2 (​ 1⁄ √ 2 m 2).

As a result, B0 is 1 metre wide, and other sizes in the B series are a half, a quarter or further fractions of a metre wide. While less common in office use, it is used for a variety of special situations. Many posters use B-series paper or a close approximation, such as 50 cm × 70 cm; B5 is a relatively common choice for books. The B series is also used for and. The B-series is widely used in the industry to describe both paper sizes and sizes, including. B3 paper is used to print two US letter or A4 pages side by side using; four pages would be printed on B2, eight on B1, etc. C series [ ].

A size chart illustrating the ISO C series. The C series is usually used for envelopes and is defined in. The area of C series sheets is the geometric mean of the areas of the A and B series sheets of the same number; for instance, the area of a C4 sheet is the geometric mean of the areas of an A4 sheet and a B4 sheet. This means that C4 is slightly larger than A4, and slightly smaller than B4.

The practical usage of this is that a letter written on A4 paper fits inside a C4 envelope, and C4 paper fits inside a B4 envelope. Some envelope formats with mixed sides from adjacent sizes (and thus an approximate aspect ratio of 2:1) are also defined in national adaptations of the ISO standard, e.g. DIN C6/C5 is 114 mm × 229 mm where the common side to C5 and C6 is 162 mm. Siemens Wincc Software more. Comparison of ISO 216 and Swedish standard SIS 014711 paper sizes between A4 and A3 sizes. The Swedish standard SS 014711 generalized the ISO system of A, B, and C formats by adding D, E, F, and G formats to it. Its D format sits between a B format and the next larger A format (just like C sits between A and the next larger B).

The remaining formats fit in between all these formats, such that the sequence of formats A4, E4, C4, G4, B4, F4, D4, H4, A3 is a, in which the dimensions grow by a factor 16√ 2 from one size to the next. However, the SIS 014711 standard does not define any size between a D format and the next larger A format (called H in the previous example). Of these additional formats, G5 (169 × 239 mm) and E5 (155 × 220 mm) are popular in Sweden and the Netherlands for printing dissertations, but the other formats have not turned out to be particularly useful in practice and they have not been adopted internationally. The Swedish and German D series basically contain the same sizes, but are offset by one, i.e. DIN D4 equals SIS D5 and so on.
