78-406: A = x × y = 1 {\textstyle a=x\times y=1} square metre, where x {\textstyle x} is the length of the shorter side and y {\textstyle y} is the length of the longer side, for the second equation both in metres. Porstmann also argued that formats for containers of paper, such as envelopes, should be 10% larger than
117-521: A 1798 French law on taxation of publications ( French : Loi sur le timbre (Nº 2136) ) that was based in part on page sizes. Searching for a standard system of paper formats on a scientific basis at the Bridge association ( German : Die Brücke ), as a replacement for the vast variety of other paper formats that had been used before, in order to make paper stocking and document reproduction cheaper and more efficient, in 1911 Wilhelm Ostwald proposed, over
156-453: A hundred years after the 1798 French law, a global standard – a world format ( Weltformat ) – for paper sizes based on the ratio 2 {\textstyle {\sqrt {2}}} , referring to the argument advanced by Lichtenberg's 1786 letter, but linking this to the metric system using 1 centimetre (0.39 in) as the width of the base format. Walter Porstmann [ de ] argued in
195-441: A larger rectangle with the aspect ratio of 2 {\textstyle {\sqrt {2}}} and double the area of each individual sheet. The ISO system of paper sizes exploits these properties of the 2 {\textstyle {\sqrt {2}}} aspect ratio. In each series of sizes (for example, series A), the largest size is numbered 0 (so in this case A0), and each successive size (A1, A2, etc.) has half
234-393: A long article published in 1918, that a firm basis for the system of paper formats, which deal with surfaces, ought not be the length but the area; that is, linking the system of paper formats to the metric system using the square metre rather than the centimetre, constrained by x y = 2 {\textstyle {\tfrac {x}{y}}={\sqrt {2}}} and area
273-510: A page from A4 to A3. Similarly, two sheets of A4 can be scaled down to fit one A4 sheet without excess empty paper. This system also simplifies calculating the weight of paper. Under ISO 536 , paper's grammage is defined as a sheet's mass in grams (g) per area in square metres (unit symbol g/m ; the nonstandard abbreviation "gsm" is also used). One can derive the grammage of other sizes by arithmetic division . A standard A4 sheet made from 80 g/m paper weighs 5 grams (0.18 oz), as it
312-503: A radius of 2.88–3.48 mm (about 1 ⁄ 8 in). This format is also referred to as CR-80 and, for travel documents, TD1 . It is commonly used for payment cards ( ATM cards, credit cards , debit cards , etc.). Today it is also used for driving licences and personal identity cards in many countries, automated fare collection system cards for public transport, in retail loyalty cards, and even crew member certificates (particularly for aircrew ). The ID-2 format
351-651: A size of 25 by 15 millimetres (1 in × 9 ⁄ 16 in), with one corner slightly ( 3 mm or 1 ⁄ 8 in) bevelled. The ID-000 size was first defined by ENV 1375–1, Identification card systems — Intersector integrated circuit(s) card additional formats — Part 1: ID-000 card size and physical characteristics. This size is used for the mini-SIM format, the second-generation format of Subscriber Identity Modules . An "informative" (i.e. non-mandatory) annex describes how an ID-000 sized card may be included in an ID-1 size card for processing (e.g. in an ID-1 reader), but with "relief areas around
390-481: Is 105 by 74 millimetres ( 4 + 1 ⁄ 8 in × 2 + 15 ⁄ 16 in), and travel documents in this format are also referred to as TD2 . This length and width are those of A7 paper. The ID-2 format is used, for example, for visas . It was previously used for the Romanian , Icelandic , German , French and many other identity cards. As of 2024, all European standard identity cards are issued in
429-454: Is 1 ⁄ 16 (four halvings, ignoring rounding) of an A0 page. Thus the weight, and the associated postage rate , can be approximated easily by counting the number of sheets used. ISO 216 and its related standards were first published between 1975 and 1995: Paper in the A series format has an aspect ratio of √ 2 (≈ 1.414, when rounded). A0 is defined so that it has an area of 1 m (11 sq ft ) before rounding to

#1732852798330468-602: Is an international standard for paper sizes , used around the world except in North America and parts of Latin America. The standard defines the " A ", " B " and " C " series of paper sizes, which includes the A4 , the most commonly available paper size worldwide. Two supplementary standards, ISO 217 and ISO 269 , define related paper sizes; the ISO 269 " C " series is commonly listed alongside
507-521: Is an international standard that defines the physical characteristics for identification cards . The characteristics specified include: The standard includes test methods for resistance to heat. The standard defines four card sizes: ID-1, ID-2, ID-3 and ID-000. All card sizes have a thickness of 760 ± 80 μm , i.e. minimum 0.68 millimetres (0.027 in) and maximum 0.84 millimetres (0.033 in). The standard defines both metric and imperial measurements, noting that: Numeric values in
546-1147: Is based on B0 with width of 1 metre (3 ft 3 in), C0 is 917 by 1,297 millimetres (36.1 in × 51.1 in), and D0 771 by 1,090 millimetres (30.4 in × 42.9 in). Series C is the basis for envelope formats. The DIN paper-format concept was soon introduced as a national standard in many other countries, for example, Belgium (1924), Netherlands (1925), Norway (1926), Switzerland (1929), Sweden (1930), Soviet Union (1934), Hungary (1938), Italy (1939), Finland (1942), Uruguay (1942), Argentina (1943), Brazil (1943), Spain (1947), Austria (1948), Romania (1949), Japan (1951), Denmark (1953), Czechoslovakia (1953), Israel (1954), Portugal (1954), Yugoslavia (1956), India (1957), Poland (1957), United Kingdom (1959), Venezuela (1962), New Zealand (1963), Iceland (1964), Mexico (1965), South Africa (1966), France (1967), Peru (1967), Turkey (1967), Chile (1968), Greece (1970), Zimbabwe (1970), Singapore (1970), Bangladesh (1972), Thailand (1973), Barbados (1973), Australia (1974), Ecuador (1974), Colombia (1975) and Kuwait (1975). It finally became both an international standard ( ISO 216) as well as
585-422: Is defined in the standard as follows: "A subsidiary series of sizes is obtained by placing the geometrical means between adjacent sizes of the A series in sequence." The use of the geometric mean makes each step in size: B0, A0, B1, A1, B2 ... smaller than the previous one by the same factor. As with the A series, the lengths of the B series have the ratio √ 2 , and folding one in half (and rounding down to
624-457: Is folded in half so that it is A5 in size, it will fit into a C5 envelope (which will be the same size as a C4 envelope folded in half). Any C n paper can be defined as C n = S × L , where (measuring in metres) Therefore The tolerances specified in the standard are: These are related to comparison between series A, B and C. The ISO 216 formats are organized around the ratio 1: √ 2 ; two sheets next to each other together have
663-539: Is its scaling. Rectangular paper with an aspect ratio of 2 {\textstyle {\sqrt {2}}} has the unique property that, when cut or folded in half midway between its longer sides, each half has the same 2 {\textstyle {\sqrt {2}}} aspect ratio as the whole sheet before it was divided. Equivalently, if one lays two same-sized sheets of paper with an aspect ratio of 2 {\textstyle {\sqrt {2}}} side by side along their longer side, they form
702-448: Is no size half-way between B n and A( n − 1) : A4, C4, B4, "D4", A3, ...; there is such a D-series in the Swedish extensions to the system. The lengths of ISO C series paper are therefore √ 2 ≈ 1.09 times those of A-series paper. The C series formats are used mainly for envelopes . An unfolded A4 page will fit into a C4 envelope. Due to same width to height ratio, if an A4 page
741-430: Is the size A4, which is 210 mm × 297 mm (8.27 in × 11.7 in) and thus almost exactly 1 ⁄ 16 square metre (0.0625 m ; 96.8752 sq in) in area. For comparison, the letter paper size commonly used in North America ( 8 + 1 ⁄ 2 in × 11 in; 216 mm × 279 mm) is about 6 mm ( 0.24 in ) wider and 18 mm ( 0.71 in ) shorter than A4. Then,
780-601: The silver ratio . An adjunct to the ISO paper sizes, particularly the A series, are the technical drawing line widths specified in ISO 128 . For example, line type A ("Continuous - thick", used for "visible outlines") has a standard thickness of 0.7 mm on an A0-sized sheet, 0.5 mm on an A1 sheet, and 0.35 mm on A2, A3, or A4. The matching technical pen widths are 0.13, 0.18, 0.25, 0.35, 0.5, 0.7, 1.0, 1.40, and 2.0 mm, as specified in ISO 9175-1 . Colour codes are assigned to each size to facilitate easy recognition by
819-413: The A and B sizes. All ISO 216, ISO 217 and ISO 269 paper sizes (except some envelopes) have the same aspect ratio , √ 2 :1 , within rounding to millimetres . This ratio has the unique property that when cut or folded in half widthways, the halves also have the same aspect ratio. Each ISO paper size is one half of the area of the next larger size in the same series. The oldest known mention of

#1732852798330858-501: The ID-1 format. ID-2 was previously also used for driving licences (including Finnish, Swedish and Icelandic) before those changed to the ID-1 format. The ID-3 format is 125 by 88 millimetres ( 4 + 15 ⁄ 16 in × 3 + 7 ⁄ 16 in), and travel documents in this format are also referred to as TD3 . This length and width are those of B7 paper. This format is commonly used for passport booklets . ID-000 specifies
897-497: The ISO 216 paper format, Mexico, Panama, Peru, Colombia, the Philippines, and Chile also use mostly U.S. paper sizes. Rectangular sheets of paper with the ratio 1: √ 2 are popular in paper folding , such as origami , where they are sometimes called "A4 rectangles" or "silver rectangles". In other contexts, the term "silver rectangle" can also refer to a rectangle in the proportion 1:(1 + √ 2 ), known as
936-489: The ISO standard) can be defined as B n = S × L , where (measuring in metres) Therefore The C series formats are geometric means between the B series and A series formats with the same number (e.g. C2 is the geometric mean between B2 and A2). The width to height ratio of C series formats is √ 2 as in the A and B series. A, B, and C series of paper fit together as part of a geometric progression , with ratio of successive side lengths of √ 2 , though there
975-545: The SI and/or Imperial measurement system [...] may have been rounded off and therefore are consistent with, but not exactly equal to, each other. Either system may be used, but the two should not be intermixed or reconverted. The original design was made using the Imperial measurement system. The ID-1 format specifies a size of 85.60 by 53.98 millimetres ( 3 + 3 ⁄ 8 in × 2 + 1 ⁄ 8 in) and rounded corners with
1014-573: The advantages of basing a paper size on an aspect ratio of 2 {\textstyle {\sqrt {2}}} is found in a letter written on 25 October 1786 by the German scientist Georg Christoph Lichtenberg to Johann Beckmann , both at the University of Göttingen . Early variants of the formats that would become ISO paper sizes A2, A3, B3, B4, and B5 then evolved in France, where they were listed in
1053-498: The always preferred formats and basis for the other series. All measures are rounded to the nearest millimetre. A0 has a surface area of 1 square metre (11 sq ft) up to a rounding error , with a width of 841 millimetres (33.1 in) and height of 1,189 millimetres (46.8 in), so an actual area of 0.999949 square metres (10.76336 sq ft); A4 is recommended as standard paper size for business, administrative and government correspondence; and A6 for postcards. Series B
1092-414: The area of the preceding sheet and can be cut by halving the length of the preceding size sheet. The new measurement is rounded down to the nearest millimetre. A folded brochure can be made by using a sheet of the next larger size (for example, an A4 sheet is folded in half to make a brochure with size A5 pages). An office photocopier or printer can be designed to reduce a page from A4 to A5 or to enlarge
1131-457: The drafter. Like the paper sizes, these pen widths increase by a factor of √ 2 , so that particular pens can be used on particular sizes of paper, and then the next smaller or larger size can be used to continue the drawing after it has been reduced or enlarged, respectively. The earlier DIN 6775 standard upon which ISO 9175-1 is based also specified a term and symbol for easy identification of pens and drawing templates compatible with
1170-422: The nearest 1 millimetre (0.039 in). Successive paper sizes in the series (A1, A2, A3, etc.) are defined by halving the area of the preceding paper size and rounding down, so that the long side of A( n + 1) is the same length as the short side of A n . Hence, each next size is nearly exactly half the area of the prior size. So, an A1 page can fit two A2 pages inside the same area. The most used of this series
1209-555: The nearest millimetre) gives the next in the series. The shorter side of B0 is exactly 1 metre. There is also an incompatible Japanese B series which the JIS defines to have 1.5 times the area of the corresponding JIS A series (which is identical to the ISO A series). Thus, the lengths of JIS B series paper are √ 1.5 ≈ 1.22 times those of A-series paper. By comparison, the lengths of ISO B series paper are √ 2 ≈ 1.19 times those of A-series paper. Any B n paper (according to

1248-457: The official United Nations document format in 1975, and it is today used in almost all countries in the world, with the exception of several countries in the Americas. In 1977, a large German car manufacturer performed a study of the paper formats found in their incoming mail and concluded that out of 148 examined countries, 88 already used the A series formats. The main advantage of this system
1287-632: The paper format itself. In 1921, after a long discussion and another intervention by Porstmann, the Standardisation Committee of German Industry ( Normenausschuß der deutschen Industrie , or NADI in short), which is the German Institute for Standardisation ( Deutsches Institut für Normung , or DIN in short) today, published German standard DI Norm 476 the specification of four series of paper formats with ratio 2 {\textstyle {\sqrt {2}}} , with series A as
1326-532: The perimeter of the ID-000 size card to allow it to be removed from the ID-1 size card without punching tools". An ID-1 size card containing an ID-000 size card is denoted as ID-1/000 . This was the common design of SIMs when mini-SIMs were common, usually being issued as standard SIMs, i.e. in ID-1 format, with a removable ID-000 section that, when removed, was a mini-SIM. The standard specifies requirements for such physical characteristics as: ISO 216 ISO 216
1365-403: The same as that of a rectangle half its size, y / x /2 , which means that x / y = y / x /2 , which reduces to x / y = √ 2 ; in other words, an aspect ratio of 1: √ 2 . Any A n paper can be defined as A n = S × L , where (measuring in metres) Therefore The B series
1404-464: The same ratio, sideways. In scaled photocopying, for example, two A4 sheets reduced to A5 size fit exactly onto one A4 sheet, and an A4 sheet in magnified size onto an A3 sheet; in each case, there is neither waste nor want. The principal countries not generally using the ISO paper sizes are the United States and Canada, which use North American paper sizes . Although they have also officially adopted

1482-432: The size of A5 paper is half of A4, i.e. 148 mm × 210 mm ( 5.8 in × 8.3 in ). The geometric rationale for using the square root of 2 is to maintain the aspect ratio of each subsequent rectangle after cutting or folding an A-series sheet in half, perpendicular to the larger side. Given a rectangle with a longer side, x , and a shorter side, y , ensuring that its aspect ratio, x / y , will be
1521-489: The standard, called Micronorm , which may still be found on some technical drafting equipment. DIN 476 provides for formats larger than A0, denoted by a prefix factor. In particular, it lists the formats 2A0 and 4A0, which are twice and four times the size of A0 respectively: While not formally defined, ISO 216:2007 notes them in the table of Main series of trimmed sizes (ISO A series) as well: "The rarely used sizes [2A0 and 4A0] which follow also belong to this series." 2A0
