There is an additional paper size, 8 in × 10 1⁄2 in (200 mm × 270 mm), which has been given the name of government letter by the IEEE Printer Working Group (PWG). [17] It was commissioned by Herbert Hoover, when he was Secretary of Commerce, to be used for U.S. government forms, ostensibly to allow discounts on the purchase of paper for schools, but more likely because of the standard use of cutting books (after cover) and paper from standard paper to create consistency and allow for “bleed” printing. Later, as photocopiers proliferated, citizens wanted to make photocopies of forms, but machines generally did not have paper of this size in their containers. So Ronald Reagan asked the U.S. government to switch to the regular letter format, which is both half an inch longer and wider. [19] The old size of government is still commonly used in spiral-bound notebooks, children`s writings, etc., due to the reduction of current letter measurements. In 1975, so many countries used the German system that it was established as an ISO standard as well as the official United Nations document format. In 1977, A4 was the standard letter format in 88 out of 148 countries.
Today, the standard has been adopted by every country in the world, with the exception of the United States and Canada. In Mexico, Costa Rica, Colombia, Venezuela, Chile and the Philippines, the American letter format is still used despite the official adoption of the ISO standard. Among other things, DIN 5008 (formerly DIN 676) prescribes two variants, A and B, for the position of the address field on the first page of a business letter and the corresponding folding of sheet A4, so that the only visible part of the main content is the subject line. “Blocks of letters” are 8 1⁄2 in × 11 inches (220 mm × 280 mm), while the term “legal stamp” is often used by laymen to refer to stamps of various sizes, including those of 8 1⁄2 in × 14 inches (220 mm × 360 mm). Stenographers use 6-inch × 9-inch (150 mm × 230 mm) “stenographers”. This paper does not yet exist in Indonesia, a type of paper that is legally used in America. The size is close to the F4 paper size until sometimes the printer settings use this paper size. The legal paper size is 21.6 x 35.6 cm or 8.5 x 14 inches. Most industry standards express grain direction last when specifying dimensions (i.e., 17 × 11 inches are short-grain paper and 11 × 17 inches are long-grain paper), although grain orientation may be explicitly specified with an underscore (11 × 17 is short-grained) or the letter “M” for “machine” (11M × 17 is short-grained). Grain is important because paper cracks when folded over grain: for example, if a sheet needs to be folded 17 × 11 inches to divide the sheet into two halves of 8.5 × 11, the grain will be along the 11-inch side.
[30] Paper intended to be introduced into a machine that folds paper around the rolls, such as a printing press, photocopier or typewriter, must first be fed with the edge of the grain so that the axis of the rolls runs along the particle size. The first standard for paper size in the Soviet Union was OST 303 in 1926. Six years later, it was replaced by OST 5115, which generally followed the principles of DIN 476 but used lowercase Cyrillic letters instead of uppercase Latin letters, moved the second row so that б0 (B0) was approximately equal to B1 and, more importantly, had slightly different sizes: [12] Extension of American standards, halving of letter size, 5 1⁄2 in × 8 1⁄2 in (140 mm × 220 mm), meets the needs of many applications. It is variously known as a statement, stationery, memo, half-letter, half-A (of ANSI sizes) or simply half-size. Like the similar-sized ISO A5, it is used for everything from writing personal letters to official aeronautical charts. Organizers, notepads, and journals also often use this paper size. Thus, 3-ring backrests are also available in this size. Brochures of this size are created using landscape word processing tools in two columns on stationery, which are then cut or folded into the final format. Series B is widely used in the printing industry to describe both paper and press sizes, including digital presses. B3 paper is used to print two American letters or A4 pages side by side with the imposition. four pages would be printed on B2, eight on B1, etc.
The C series is defined in ISO 269, which was withdrawn in 2009 without replacement, but is still specified in several national standards. It is mainly used for envelopes. The area of the C series sheets is the geometric mean of the areas of the A and B series sheets with the same number; For example, 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.
