Comparison of the most common paper sizes.
Comparison of the most common paper sizes.

There have been many standard sizes of paper at different times and in different countries, but today there are two widespread systems in use: the international standard (A4 and its siblings) and the North American sizes. Paper is thin material mainly used for writing upon printing upon or packaging

The international paper size standard, ISO 216, is based on the German DIN 476 standard for paper sizes. A series Paper in the A series format has a 1\sqrt{2} aspect ratio although this is rounded to the nearest millimetre Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe.

ISO paper sizes are all based on a single aspect ratio of the square root of two, or approximately 1:1. The aspect ratio of an Image is its width divided by its height The square root of 2, also known as Pythagoras' Constant, often denoted by \sqrt{2}   or   √2 4142. The advantages of basing a paper size upon this ratio were already noted in 1786 by the German scientist Georg Lichtenberg (in a letter to Johann Beckmann): if a sheet with aspect ratio √2 is horizontally divided into two equal halves, then the halves will again have aspect ratio √2. Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe. Georg Christoph Lichtenberg ( 1 July 1742 – 24 February 1799) was a German Scientist, Satirist and In the beginning of the twentieth century, Dr Walter Porstmann turned Lichtenberg's idea into a proper system of different paper sizes. Porstmann's system was introduced as a DIN standard (DIN 476) in Germany in 1922, replacing a vast variety of other paper formats. Deutsches Institut für Normung eV ( DIN; in English, the German Institute for Standardization) is the German national organization for Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe. Even today the paper sizes are called "DIN A4" in everyday use in Germany.

The DIN 476 standard spread quickly to other countries, and before the outbreak of World War II it had been adopted by the following countries:

During the war it was adopted by Uruguay (1942), Argentina (1943) and Brazil (1943); and directly afterwards the standard continued to spread to other countries:

By 1975 so many countries were using the German system that it was established as an ISO standard, as well as the official United Nations document format.

The largest standard size, A0, has an area of 1 m². M^2 redirects here For other uses see M². CM2 redirects here The length of the long side of the sheet in metres is the 4th root of 2—approximately 1. 189 metres. The short side is the reciprocal of this number, approximately 0. In Mathematics, a multiplicative inverse for a number x, denoted by 1&frasl x or x &minus1 is a number which 841 metres. A1 is formed by cutting a piece of A0 into two equal area rectangles. Because of the choice of lengths, the aspect ratio is the same for A1 as for A0 (as it is for A2, A3, etc). This particular measurement system was chosen to allow folding of one standard size into another, which cannot be accomplished with traditional paper sizes.

Brochures are made by using material at the next size up i. e. material at A3 is folded to make A4 brochures. Similarly, material at A4 is folded to make A5 brochures. A series Paper in the A series format has a 1\sqrt{2} aspect ratio although this is rounded to the nearest millimetre

It also allows scaling without loss of image from one size to another. Thus an A4 page can be enlarged to A3 and retain the exact proportions of the original document. Office photocopiers in countries that use ISO 216 paper often have one tray filled with A4 and another filled with A3. A simple method is usually provided (e. g. one button press) to enlarge A4 to A3 or reduce A3 to A4. This also allows two sheets of A4 (or any other size) to be scaled down and fit exactly 1 sheet without any cutoff or margins.

There is also a much less common B series. The area of B series sheets is the geometric mean of successive A series sheets. The geometric mean in Mathematics, is a type of Mean or Average, which indicates the central tendency or typical value of a set of numbers So, B1 is between A0 and A1 in size, with an area of 0. 71 m² (\sqrt{0.5}). As a result, B0 has one side 1-metre long, and other sizes in the B series have one side that is a half, quarter or eighth of a metre. 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 envelopes and passports. An envelope is a Packaging product usually made of flat planar material such as Paper or cardboard and designed to contain a flat object which in a postal-service A passport is a document issued by a national government which certifies for the purpose of international travel the identity and nationality of its holder

The C series is used only for envelopes and is defined in ISO 269. 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 B4 slightly larger than C4. The practical usage of this is that a letter written on A4 paper fits inside a C4 envelope, and a C4 envelope fits inside a B4 envelope.

The scalability also means that less paper (and hence money) is wasted by printing companies.

German extensions

The German standard DIN 476 was published in 1922 and is the original specification of the A and B sizes. Deutsches Institut für Normung eV ( DIN; in English, the German Institute for Standardization) is the German national organization for It differs in two details from its international successor:

DIN 476 provides an extension to formats larger than A0, denoted by a prefix factor. In particular, it lists the two formats 2A0, which is twice the area of A0, and 4A0, which is four times A0:

4A0 1682 × 2378 66. 2 × 93. 6

DIN 476 also specifies slightly tighter tolerances:

Swedish extensions

The Swedish standard SIS 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 geometric progression, in which the dimensions grow by a factor 21/8 from one size to the next. In Mathematics, a geometric progression, also known as a geometric sequence, is a Sequence of Numbers where each term after the first is found 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 (169x239 mm) and E5 (155x220 mm) are popular in Sweden for printing dissertations [1], but the other formats have not turned out to be particularly useful in practice and they have not caught on internationally.

Japanese B-series variant

The JIS defines two main series of paper sizes. This article is about Japanese Industrial Standards in general see JIS encoding for the character encoding used in representing the Japanese language for computer software The JIS A-series is identical to the ISO A-series, but with slightly different tolerances. The area of B-series paper is 1. 5 times that of the corresponding A-paper, so the length ratio is approximately 1. 22 times the length of the corresponding A-series paper. The aspect ratio of the paper is the same as for A-series paper. Both A- and B-series paper is widely available in Japan and most photocopiers are loaded with at least A4 and B4 paper.

There are also a number of traditional paper sizes, which are now used mostly only by printers. The most common of these old series are the Shiroku-ban and the Kiku paper sizes.

North American paper sizes

Loose sizes

Current standard sizes of U. S. paper are a subset of the traditional sizes referred to below. "Letter", "legal", "ledger", and "tabloid" are by far the most commonly used of these for everyday activities. The origin of the exact dimensions of "letter" size paper (8½ in × 11 in, 215. 9 mm × 279. 4 mm) are lost in tradition and not well documented. The American Forest and Paper Association argues that the dimension originates from the days of manual paper making, and that the 11 inch length of the page is about a quarter of "the average maximum stretch of an experienced vatman's arms. "[1] However, this does not explain the width or aspect ratio.

There is an additional paper size, to which the name "government-letter" was given by the IEEE Printer Working Group: the 8 in × 10½ in (203. The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is an international Non-profit, professional organization The Printer Working Group charter is to develop standards that make printers operating systems and applications work better 2 mm × 266. 7 mm) paper that is used in the United States for children's writing. It was prescribed by Herbert Hoover when he was Secretary of Commerce to be used for U. Herbert Clark Hoover (August 10 1874 &ndash October 20 1964 was the thirty-first President of the United States (1929–1933 The United States Secretary of Commerce is the head of the United States Department of Commerce concerned with business and industry the Department states its mission to S. government forms, apparently to enable discounts from the purchase of paper for schools. In later years, as photocopy machines proliferated, citizens wanted to make photocopies of the forms, but the machines did not generally have this size paper in their bins. Ronald Reagan therefore had the U. S. government switch to regular letter size (8½ in × 11 in). The 8 in × 10½ in size is still commonly used in spiral-bound notebooks and the like. A notebook (also notepad, writing pad, drawing pad, legal pad, etc

An alternative explanation in the past for the difference between "government size" (as government-letter size was referred to at the time) and letter size paper was that the slightly smaller sheet used less paper, and therefore saved the government money in both paper and filing space. However, when Reagan prescribed the change to letter size, it was commonly stated that U. S. paper manufacturers had standardized their production lines for letter size, and were meeting government orders by trimming ½" each from two sides of letter-size stock; thus the government was allegedly paying more for its smaller paper size before Reagan abolished it. The different paper size also reportedly restricted the government's ability to take advantage of modular office furniture designs, common in the 1980s, whose cabinets were designed for letter size paper.

U. S. paper sizes are currently standard in the United States and the Philippines. The latter uses U. S. "letter", but the Philippine "legal" size is 8½ in × 13 in (215. 9 mm × 330. 2 mm). ISO sizes are available, but not widely used, in both the U. S. and the Philippines.

In Canada, U. Country to "Dominion of Canada" or "Canadian Federation" or anything else please read the Talk Page S. paper sizes are a de facto standard. The government, however, uses a combination of ISO paper sizes, and CAN 2-9. 60M "Paper Sizes for Correspondence" specifies P1 through P6 paper sizes, which are the U. S. paper sizes rounded to the nearest 5 mm. [3]

Mexico has adopted the ISO standard, but U. The United Mexican States ( or commonly Mexico (ˈmɛksɪkoʊ () is a federal constitutional Republic in North America. S. "letter" format is still the system in use throughout the country. It is virtually impossible to encounter ISO standard papers in day-to-day uses, with "Carta 216 mm × 279 mm" (letter), "Oficio 216 mm × 340 mm" (legal) and "Doble carta" (ledger/tabloid) being nearly universal. U. S. sizes are also widespread and in common use in Colombia [2].

ANSI paper sizes

A size chart illustrating the ANSI sizes.
A size chart illustrating the ANSI sizes.

In 1995, the American National Standards Institute adopted ANSI/ASME Y14. 1 which defined a regular series of paper sizes based upon the de facto standard 8½ in × 11 in "letter" size which it assigned "ANSI A". This series also includes "ledger"/"tabloid" as "ANSI B". This series is somewhat similar to the ISO standard in that cutting a sheet in half would produce two sheets of the next smaller size. Unlike the ISO standard, however, the arbitrary aspect ratio forces this series to have two alternating aspect ratios. The ANSI series is shown below.

With care, documents can be prepared so that the text and images fit on either ANSI or their equivalent ISO sheets at 1:1 reproduction scale.

Other, larger sizes continuing the alphabetic series illustrated above exist, but it should be noted that they are not part of the series per se, because they do not exhibit the same aspect ratios. For example, Engineering F size (28 in × 40 in, 711. 2 mm × 1016. 0 mm) also exists, but is rarely encountered, as are G, H, … N size drawings. G size is 22½ in (571. 5 mm) high, but variable width up to 90 in (2286 mm) in increments of 8½ in, i. e. , roll format. H and larger letter sizes are also roll formats. Such sheets were at one time used for full-scale layouts of aircraft parts, wiring harnesses and the like, but today are generally not needed, due to widespread use of computer-aided design (CAD) and computer-aided manufacturing (CAM). Computer-aided manufacturing ( CAM) is the use of computer-based software tools that assist engineers and machinists in manufacturing or prototyping product components

Architectural sizes

In addition to the ANSI system as listed above, there is a corresponding series of paper sizes used for architectural purposes. The term architecture (from Greek αρχιτεκτονικήarchitektoniki) can be used to mean a process a profession or documentation This series also shares the property that bisecting each size produces two of the size below. It may be preferred by North American architects because the aspect ratios (4:3 and 3:2) are ratios of small integers, unlike their ANSI (or ISO) counterparts. Furthermore, the aspect ratio 4:3 matches the traditional aspect ratio for computer displays. The architectural series, usually abbreviated "Arch", is shown below:

Tablet sizes

The sizes listed above are for paper sold loosely in reams. A notebook (also notepad, writing pad, drawing pad, legal pad, etc Various measures of Paper quantity have been and are in use; Writing paper measurements 25 sheets = 1 quire 500 sheets = 20 quires = 1 ream 1000 sheets = There are many sizes of tablets of paper, that is, sheets of paper kept from flying around by being bound at one edge, usually by a strip of plastic or hardened PVA adhesive. Polyvinyl acetate ( PVA or PVAc) is a Rubbery Synthetic polymer. Often there is a pad of cardboard (also known as chipboard or greyboard) at the bottom of the stack. Paperboard is a Paper -like material usually over ten mils (0 Such a tablet serves as a portable writing surface, and the sheets often have lines printed on them, usually in blue, to make writing in a line easier. An older means of binding is to have the sheets stapled to the cardboard along the top of the tablet; there is a line of perforated holes across every page just below the top edge from which any page may be torn off. Lastly, a pad of sheets each weakly stuck with adhesive to the sheet below, trademarked as "Post-It" or "Stick-Em" and available in various sizes, serve as a sort of tablet.

"Letter pads" are of course 8½ by 11 inches, while the term "legal pad" is often used by laymen to refer to pads of various sizes including those of 8½ by 14 inches. There are "steno pads" (used by stenographers) of 6 by 9 inches.

Of course, in countries where the ISO sizes are standard, most notebooks and tablets are sized to ISO specifications (for example, most newsagents in Australia stock A4 and A3 tablets).

Traditional inch-based paper sizes

Traditionally, a number of different sizes were defined for large sheets of paper, and paper sizes were defined by the sheet name and the number of times it had been folded. Thus a full sheet of "royal" paper was 25 × 20 inches, and "royal octavo" was this size folded three times, so as to make eight sheets, and was thus 10 by 6¼ inches.

Imperial sizes were used in the United Kingdom and its territories. Some of the base sizes were as follows:

Traditional sizes for writing paper in the United Kingdom [3], :

Name in × in
Quarto 10 × 8
Imperial 9 × 7
Kings 8 × 6½
Dukes 7 × 5½

The common divisions and their abbreviations include:

Name Abbr. Folds Leaves Pages
Folio fo, f 1 2 4
Quarto 4to 2 4 8
Sexto, sixmo 6to, 6mo 3 6 12
Octavo 8vo 3 8 16
Duodecimo, twelvemo 12mo 4 12 24
Sextodecimo, sixteenmo 16mo 4 16 32

Foolscap folio is often referred to simply as 'folio' or 'foolscap'. Foolscap folio (commonly contracted to foolscap or folio) is Paper cut to the size of 8½ × 13½ Inches (216 × 343 mm Similarly, 'quarto' is more correctly 'copy draught quarto'.

Many of these sizes were only used for making books (see bookbinding), and would never have been offered for ordinary stationery purposes. A Book is a set or collection of written printed illustrated or blank sheets made of Paper, Parchment, or other material usually fastened together Bookbinding is the process of physically assembling a Book from a number of folded or unfolded sheets of Paper or other material

Transitional paper sizes

PA series

PA4-based series
Name mm × mm Ratio
PA0 840 × 1120 3:4
PA1 560 × 840 2:3
PA2 420 × 560 3:4
PA3 280 × 420 2:3
PA4 210 × 280 3:4
PA5 140 × 210 2:3
PA6 105 × 140 3:4
PA7 70 × 105 2:3
PA8 52 × 70 ≈3:4
PA9 35 × 52 ≈2:3
PA10 26 × 35 ≈3:4

A transitional size called PA4 (210 mm × 280 mm, 8¼ in × 11 in) was proposed for inclusion into the ISO 216 standard in 1975. It has the height of Canadian P4 paper (215 mm × 280 mm, about 8½ in × 11 in) and the width of international A4 paper (210 mm × 297 mm). The table to the right shows how this format can be generalized into an entire format series.

The PA formats did not end up in ISO 216, because the committee felt that the set of standardized paper formats should be kept to the minimum necessary. However, PA4 remains of practical use today. In landscape orientation, it has the same 4:3 aspect ratio as the displays of traditional TV sets, most computers and data projectors. Landscape comprises the visible features of an area of land including physical elements such as Landforms living elements of flora and fauna abstract elements such as lighting A visual display unit, often called simply a monitor or display, is a piece of Electrical equipment which displays images generated from the Video A video projector takes a Video signal and projects the corresponding image on a Projection screen using a lens system PA4 is therefore a good choice as the format of computer presentation slides. At the same time, PA4 is the largest format that fits on both A4 and U. S. /Canadian "Letter" paper without resizing.

PA4 is used today by many international magazines, because it can be printed easily on equipment designed for either A4 or U. Magazines, periodicals or serials are Publications generally published on a regular schedule containing a variety of articles, generally S. "Letter".

Antiquarian

Although the movement is towards the international standard metric paper sizes, on the way there from the traditional ones there has been at least one new size just a little larger than that used internationally. British architects and industrial designers once used a size called "Antiquarian" as listed above, but given in the New Metric Handbook (Tutt & Adler 1981) as 813 mm × 1372 mm. This is a little larger than the A0 size. So for a short time, a size called A0a (1000 mm × 1370 mm) was used in Britain.

F4

F4 (210 mm × 330 mm) is common in Southeast Asia and Australia, and is sometimes called "foolscap". F4 is a Paper format of size 210 mm x 330 mm Although metric based on the A4 paper size, and named to suggest that it is part of the official ISO It has the same width as A4, but is longer.
