</P><P>Rounded to the nearest millimetre, A0 is the format 841 by 1,189 millimetres (33.1 in × 46.8 in).
</P><P>Successive paper sizes in the series A1, A2, A3, and so forth, are defined by halving the preceding paper size across the larger dimension. This also effectively halves the area of each sheet. The most frequently used paper size is A4 measuring 210 by 297 millimetres (8.3 in × 11.7 in).
</P><P>The significant advantage of this system is its scaling: if a sheet with an aspect ratio of <SPAN class="nowrap">√<SPAN style="border-top:1px solid; padding:0 0.1em;">2</SPAN></SPAN> is divided into two equal halves parallel to its shortest sides, then the halves will again have an aspect ratio of <SPAN class="nowrap">√<SPAN style="border-top:1px solid; padding:0 0.1em;">2</SPAN></SPAN>. Folded brochures of any size can be made by using sheets of the next larger size, e.g. A4 sheets are folded to make A5 brochures. The system allows scaling without compromising the <A href="https://en.wikipedia.org/wiki/Aspect_ratio" title="Aspect ratio">aspect ratio</A> from one size to another—as provided by office photocopiers, e.g. enlarging A4 to A3 or reducing A3 to A4. Similarly, two sheets of A4 can be scaled down and fit exactly on one sheet without any cutoff or margins.
</P><P>The behavior of the aspect ratio is easily proven. On a sheet of paper, let <I>a</I> be the long side and <I>b</I> be the short side. Since

<P>Thus folding the paper preserves the aspect ratio.
</P><P><A href="https://en.wikipedia.org/wiki/Paper_density#Basis_weight" title="Paper density">Weights</A> are easy to calculate as well: a standard A4 sheet made from 80 g/m<SUP>2</SUP> paper weighs 5 g (as it is ​<SPAN class="frac nowrap"><SUP>1</SUP>⁄<SUB>16</SUB></SPAN> of an A0 page, measuring 1 m<SUP>2</SUP>), allowing one to easily compute the weight—and associated postage rate—by counting the number of sheets used.
</P><P>The advantages of basing a paper size upon an aspect ratio of <SPAN class="nowrap">√<SPAN style="border-top:1px solid; padding:0 0.1em;">2</SPAN></SPAN> were first noted in 1786 by the <A href="https://en.wikipedia.org/wiki/Germany" title="Germany">German</A> scientist and philosopher <A href="https://en.wikipedia.org/wiki/Georg_Christoph_Lichtenberg" title="Georg Christoph Lichtenberg">Georg Christoph Lichtenberg</A>.<SUP id="cite_ref-3" class="reference"><A href="#cite_note-3">[3]</A></SUP> The formats that became A2, A3, B3, B4 and B5 were developed in France on proposition of the mathematician <A href="https://en.wikipedia.org/wiki/Lazare_Carnot" title="Lazare Carnot">Lazare Carnot</A> and published for judiciary purpose in 1798 during the <A href="https://en.wikipedia.org/wiki/French_Revolution" title="French Revolution">French Revolution</A>.<SUP id="cite_ref-B237_4-0" class="reference"><A href="#cite_note-B237-4">[4]</A></SUP> Early in the 20th 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. Even today, the paper sizes are called "DIN A4" (<SMALL>IPA: </SMALL><SPAN title="Representation in the International Phonetic Alphabet (IPA)" class="IPA"><A href="https://en.wikipedia.org/wiki/Help:IPA/Standard_German" title="Help:IPA/Standard German">[diːn.ʔaː.fiːɐ̯]</A></SPAN>) in everyday use in Germany and Austria.

<P>The C series is defined in <A href="https://en.wikipedia.org/wiki/ISO_269" class="mw-redirect" title="ISO 269">ISO 269</A>, which was withdrawn in 2009 without a replacement, but is still specified in several national standards. It is primarily used for envelopes. The area of C series sheets is the geometric mean of the areas of the <A href="#ISO_A">A</A> and <A href="#ISO_B">B series</A> 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 both A4 and C4 paper fits inside a B4 envelope.
</P><P>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.

<P>The α variables are the distinct first terms in the three <A href="https://en.wikipedia.org/wiki/Geometric_progression" title="Geometric progression">geometric progressions</A> of the same <I>common-ratio</I> equal to the square root of two. Each of the three geometric progressions (corresponding to the three <A href="#ISO_A">series A</A>, <A href="#ISO_B">B</A>, <A href="#ISO_C">C</A>) is formed by all possible paper dimensions (length and width) of the series arranged in a decreasing order. This interesting arrangement of dimensions is also very useful - not only it forms a geometric progression with easy to remember formulae, it also has that each consecutive pair of values (like a sliding window of size 2) will automatically correspond to the dimensions of a standard paper format in the series.

<P>The German standard DIN 476 was published on 18 August 1922 and is the original specification of the <A href="#DIN_A">A</A>, <A href="#DIN_B">B</A> and <A href="#DIN_C">C sizes</A>. In 1991, it was split into DIN 476-1 for the A and B formats and 476-2 for the C series. The former has been withdrawn in 2002 in favor of adopting the international standard as DIN EN ISO 216, but part 2 has been retained and was last updated in 2008.
</P><P>The first and the second editions of DIN 476 from 1922 and 1925 also included a D series.

<P>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.
However, ISO 216:2007 notes 2A0 and 4A0 in the table of <I>Main series of trimmed sizes</I> (ISO A series) as well: "The rarely used sizes [2A0 and 4A0] which follow also belong to this series."

<P>The Swedish standard <A href="https://en.wikipedia.org/wiki/Swedish_Standards_Institute" class="mw-redirect" title="Swedish Standards Institute">SIS</A> 01 47 11<SUP id="cite_ref-ss014711_8-0" class="reference"><A href="#cite_note-ss014711-8">[8]</A></SUP> generalized the ISO system of <A href="#ISO_A">A</A>, <A href="#ISO_B">B</A>, and <A href="#ISO_C">C</A> 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 <A href="https://en.wikipedia.org/wiki/Geometric_progression" title="Geometric progression">geometric progression</A>, in which the dimensions grow by a factor <SPAN class="nowrap"><SUP style="margin-right: -0.5em; vertical-align: 0.8em;">16</SUP>√<SPAN style="border-top:1px solid; padding:0 0.1em;">2</SPAN></SPAN> from one size to the next. However, this SIS standard does not define any size between a D format and the next larger A format (called *H in the previous example).
</P><P>Of these additional formats, G5 (169 × 239 mm) and E5 (155 × 220 mm) are popular in Sweden and the Netherlands for printing dissertations,<SUP id="cite_ref-9" class="reference"><A href="#cite_note-9">[9]</A></SUP> but the other formats have not turned out to be particularly useful in practice. They have not been adopted internationally and the Swedish standard has been withdrawn.
</P><P>The Swedish and <A href="#DIN_D">German D series</A> basically contain the same sizes, but are offset by one, i.e. DIN D4 equals SIS D5 and so on.

<P>The Japanese standard <A href="https://en.wikipedia.org/wiki/Japanese_Industrial_Standards" title="Japanese Industrial Standards">JIS P 0138</A> defines two main series of paper sizes. The JIS A-series is identical to the <A href="#ISO_A">ISO A-series</A>, but with slightly different tolerances. The area of B-series paper is 1.5 times that of the corresponding A-paper (instead of the factor <SPAN class="nowrap">√<SPAN style="border-top:1px solid; padding:0 0.1em;">2</SPAN></SPAN> = 1.414... for the <A href="#ISO_B">ISO B-series</A>), 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, <A href="https://en.wikipedia.org/wiki/Taiwan" title="Taiwan">Taiwan</A> and China, and most photocopiers are loaded with at least A4 and either one of A3, B4 and B5 paper.

<P>A popular size for books, dubbed AB, combines the shorter edges of A4 and B4. Another two with an aspect ratio approximating <A href="https://en.wikipedia.org/wiki/16:9" class="mw-redirect" title="16:9">16:9</A> are 20% narrower variants of A6 and B6, respectively, the latter resulting from cutting B1 into <SPAN class="nowrap"><SPAN data-sort-value="40 !">4 × 10</SPAN></SPAN> sheets (thus "B40").
</P><P>There are also a number of traditional paper sizes, which are now used mostly by printers. The most common of these old series are the Shiroku-ban and the Kiku paper sizes.

<P>The Chinese standard GB/T 148–1997,<SUP id="cite_ref-11" class="reference"><A href="#cite_note-11">[11]</A></SUP> which replaced GB 148–1989, documents the standard ISO series, A and B, but adds a custom D series. This Chinese format originates from the <A href="https://en.wikipedia.org/wiki/Republic_of_China_(1912%E2%80%931949)" title="Republic of China (1912–1949)">Republic of China (1912–1949)</A>. The D series is not identical to the Swedish D series. It does not strictly follow the same principles as ISO paper sizes: The aspect ratio is only very roughly <SPAN class="nowrap">√<SPAN style="border-top:1px solid; padding:0 0.1em;">2</SPAN></SPAN>. The short side of a size is always 4 mm longer than the long side of the next smaller size. The long side of a size is always exactly – i.e. without further rounding – twice as long as the short side of the next smaller size.

<P>The first standard of paper size in the Soviet Union was OST 303 in 1926. Six years later, it was replaced by OST 5115 which generally followed DIN 476 principles, but used Cyrillic lowercase letters instead of Latin uppercase, had the second row shifted so that б<SUB>0</SUB> (B0) roughly corresponded to B1 and, more importantly, had slightly different sizes:<SUP id="cite_ref-12" class="reference"><A href="#cite_note-12">[12]</A></SUP>

<P>The general adaptation of ISO 216 in the Soviet Union, which replaced OST 5115, was GOST 9327. In its 1960 version, it lists formats down to A13, B12 and C8 and also specifies ½, ¼ and ⅛ prefixes for halving the shorter side (repeatedly) for stripe formats, e.g. ½A4 = 105 mm × 297 mm.

<P>A standard for technical drawings from 1960, GOST 3450,<SUP id="cite_ref-13" class="reference"><A href="#cite_note-13">[13]</A></SUP> introduces alternative numeric format designations to deal with very high or very wide sheets.
These 2-digit codes are based upon A4 = "11": The first digit is the factor the longer side (297 mm) is multiplied by and the second digit is the one for the shorter side (210 mm), so "24" is 2×297 mm × 4×210 mm = 594 mm × 840 mm.

The new designations were not purely numeric, but consisted of the ISO label followed by an 'x', or possibly the multiplication sign '×', and the factor, e.g. DIN 2A0 = GOST A0×2, but DIN 4A0 ≠ GOST A0×4, also listed are: A0×3, A1×3, A1×4, A2×3–A2×5, A3×3–A3×7, A4×3–A4×9. The formats ...×1 and ...×2 usually would be aliases for existing formats.

<P>ISO 5457 specifies drawing paper sizes with a trimmed size equal to the A series sizes from A4 upward. The untrimmed sizes are 3 to 4 cm larger and rounded to the nearest centimeter. A0 through A3 are used in landscape orientation, while A4 is used in portrait orientation. Designations for preprinted drawing paper include the base sizes and a suffix, either <I>T</I> for trimmed or <I>U</I> for untrimmed sheets.
</P><P>The withdrawn standard ISO 2784 did specify sizes of continuous, fan-fold forms based upon whole inches as was common for paper in continuous lengths in automatic data processing (ADP) equipment. Specifically, 12 inches (304.8 mm) were considered an untrimmed variant of the A4 height of 297 mm.

<P>A transitional size called <B>PA4</B> (210 mm × 280 mm or 8.27 in × 11.02 in), sometimes dubbed <B>L4</B>, was proposed for inclusion into the ISO 216 standard in 1975. It has the height of Canadian P4 paper (215 mm × 280 mm, about ​<SPAN class="frac nowrap">8<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>2</SUB></SPAN> in × 11 in) and the width of international A4 paper (210 mm × 297 mm or 8.27 in × 11.69 in), i.e. it uses the smaller value among the two for each side. The table shows how this format can be generalized into an entire format series.
</P><P>The PA formats did not end up in ISO 216, because the committee decided that the set of standardized paper formats should be kept to the minimum necessary.<SUP class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<I><A href="https://en.wikipedia.org/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><SPAN title="This claim needs references to reliable sources. (December 2016)">citation needed</SPAN></A></I>]</SUP> However, PA4 remains of practical use today. In <A href="https://en.wikipedia.org/wiki/Landscape_format" class="mw-redirect" title="Landscape format">landscape</A> orientation, it has the same 4:3 aspect ratio as the displays of traditional TV sets, some <A href="https://en.wikipedia.org/wiki/Computer_displays" class="mw-redirect" title="Computer displays">computer displays</A> (e.g. <A href="https://en.wikipedia.org/wiki/IPad" title="IPad">iPad</A>) and <A href="https://en.wikipedia.org/wiki/Data_projector" class="mw-redirect" title="Data projector">data projectors</A>. PA4, with appropriate <A href="https://en.wikipedia.org/wiki/Margin_(typography)" title="Margin (typography)">margins</A>, is therefore a good choice as the format of presentation slides.
</P><P>As a compromise between the two most popular paper sizes globally, PA4 is used today by many international <A href="https://en.wikipedia.org/wiki/Magazine" title="Magazine">magazines</A>, because it can be printed easily on equipment designed for either A4 or US Letter. That means it is not as much a paper size than a page format. Apple, for instance, requires this format for digital music album booklets.<SUP id="cite_ref-15" class="reference"><A href="#cite_note-15">[15]</A></SUP>
</P><P>The size 210 mm × 280 mm was documented in the Canadian standard CAN2-200.2-M79 "Common Image Area for Paper Sizes P4 and A4".<SUP id="cite_ref-16" class="reference"><A href="#cite_note-16">[16]</A></SUP>

<P>A non-standard F4 paper size is common in Southeast Asia. It is a transitional size with the shorter side from ISO A4 (210 mm, ​<SPAN class="frac nowrap">8<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>4</SUB></SPAN> inch) and the longer side from British Foolscap (13 inch, 330 mm) and is sometimes known as <I>(metric) foolscap</I> or <I>folio</I> as well. It is exactly ​<SPAN class="frac nowrap"><SUP>1</SUP>⁄<SUB>9</SUB></SPAN>, i.e. 33 mm, longer than A4 or, conversely, A4 is exactly 90% the height of F4.
</P><P>In Indonesia and the Philippines, "F4" paper is slightly broader: 215 × 330 mm, i.e. basically <A href="#Foolscap">Foolscap</A> 8.5 × 13 in. In Indonesia it is sometimes called <I>folio</I>, while in Philippines it is sometimes also called <I>long bond</I>.
</P><P>A sheet of F4 can be cut from a sheet of SRA4 with very little wastage. The size is also smaller than its <A href="#Swedish_extensions">Swedish equivalent</A> SIS F4 at 239 mm × 338 mm.

<P>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.
</P><P>British architects and industrial designers once used a size called "Antiquarian", 31 in × 53 in (787 mm × 1,346 mm), as listed <A href="#Traditional_inch-based_paper_sizes">above</A>, but given in the <I>New Metric Handbook</I> (Tutt &#x000026; Adler 1981) as 813 mm × 1,372 mm (32 in × 54 in) for board size. This is a little larger than ISO A0, 841 mm × 1189 mm. So for a short time, a size called <B>A0a</B> of 1,000 mm × 1,370 mm (39.4 in × 53.9 in) was used in Britain, which is actually just a slightly shorter version of ISO B0 at 1414 mm.

<P>The most common paper sizes used for commercial and industrial printing in Colombia are based upon a size referred to as <I>pliego</I> that is ISO B1 (707 mm × 1000 mm) cut to full decimetres. Smaller sizes are derived by halving as usual and just get a vulgar fraction prefix: <I>​<SPAN class="frac nowrap"><SUP>1</SUP>⁄<SUB>2</SUB></SPAN> pliego</I> and <I>​<SPAN class="frac nowrap"><SUP>1</SUP>⁄<SUB>4</SUB></SPAN> pliego</I>.

<P>The United States, Canada, and the Philippines<SUP id="cite_ref-CLDR_1-1" class="reference"><A href="#cite_note-CLDR-1">[1]</A></SUP> primarily use a different system of paper sizes from the rest of the world. The current standard sizes are unique to those countries, although due to the size of the North American market and proliferation of both software and printing hardware from the region, other parts of the world have become increasingly familiar with these sizes (though not necessarily the paper itself).

<P><I>Letter, Legal</I> and <I>Ledger/Tabloid</I> are by far the most commonly used of these for everyday activities, and the only ones included in <A href="https://en.wikipedia.org/wiki/Cascading_Style_Sheets" title="Cascading Style Sheets">Cascading Style Sheets</A> (CSS).
</P><P>The origins of the exact dimensions of Letter size paper 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."<SUP id="cite_ref-US_19-0" class="reference"><A href="#cite_note-US-19">[19]</A></SUP> However, this does not explain the width or aspect ratio.
</P><P>Outside of North America, Letter size may also be known as "American Quarto".<SUP id="cite_ref-20" class="reference"><A href="#cite_note-20">[20]</A></SUP> If one accepts some trimming, the size is indeed one quarter of the old Imperial paper size known as Demy, <SPAN class="frac nowrap">17<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>2</SUB></SPAN> in × <SPAN class="frac nowrap">22<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>2</SUB></SPAN> in (444 mm × 572 mm).<SUP id="cite_ref-21" class="reference"><A href="#cite_note-21">[21]</A></SUP> Printer manufacturers, however, recognize inch-based <I>Quarto</I> as 10.83 in (275 mm) long.<SUP id="cite_ref-PWG_17-1" class="reference"><A href="#cite_note-PWG-17">[17]</A></SUP>

<P>US paper sizes are currently standard in the United States and are the most commonly used formats at least in the Philippines, most of <A href="https://en.wikipedia.org/wiki/Mesoamerica" title="Mesoamerica">Mesoamerica</A><SUP id="cite_ref-22" class="reference"><A href="#cite_note-22">[22]</A></SUP> and Chile. The latter use US Letter, but their Legal size is one inch shorter than its US equivalent.<SUP id="cite_ref-23" class="reference"><A href="#cite_note-23">[23]</A></SUP>
</P><P>Mexico and Colombia, for instance, have adopted the ISO standard, but US 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 <I>Carta</I> (Letter), <I>Oficio</I> (Government-Legal) and <I>Doble carta</I> (Ledger/Tabloid) being nearly universal. 
Printer manufacturers, however, recognize <I>Oficio</I> as 13.4 in (340 mm) long.<SUP id="cite_ref-PWG_17-2" class="reference"><A href="#cite_note-PWG-17">[17]</A></SUP>

<P>There is an additional paper size, 8 in × <SPAN class="frac nowrap">10<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>2</SUB></SPAN> in (200 mm × 270 mm), to which the name <I>Government-Letter</I> was given by the <A href="https://en.wikipedia.org/wiki/IEEE" class="mw-redirect" title="IEEE">IEEE</A> <A href="https://en.wikipedia.org/wiki/Printer_Working_Group" title="Printer Working Group">Printer Working Group</A> (PWG).<SUP id="cite_ref-PWG_17-3" class="reference"><A href="#cite_note-PWG-17">[17]</A></SUP> It was prescribed by <A href="https://en.wikipedia.org/wiki/Herbert_Hoover" title="Herbert Hoover">Herbert Hoover</A> when he was <A href="https://en.wikipedia.org/wiki/Secretary_of_Commerce" class="mw-redirect" title="Secretary of Commerce">Secretary of Commerce</A> to be used for US government forms, apparently to enable discounts from the purchase of paper for schools, but more likely due to the standard use of trimming books (after binding) and paper from the standard letter size paper to produce consistency and allow "bleed" printing. 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. <A href="https://en.wikipedia.org/wiki/Ronald_Reagan" title="Ronald Reagan">Ronald Reagan</A> therefore had the US government switch to regular Letter size, which is both half an inch longer and wider.<SUP id="cite_ref-US_19-1" class="reference"><A href="#cite_note-US-19">[19]</A></SUP> The former government size is still commonly used in spiral-bound <A href="https://en.wikipedia.org/wiki/Notebook" title="Notebook">notebooks</A>, for children's writing and the like, a result of trimming from the current Letter dimensions.
</P><P>By extension of the American standards, the halved Letter size, <SPAN class="frac nowrap">5<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>2</SUB></SPAN> in × <SPAN class="frac nowrap">8<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>2</SUB></SPAN> in (140 mm × 220 mm), meets the needs of many applications. It is variably known as <I>Statement</I>, <I>Stationery</I>, <I>Memo</I>, <I>Half Letter</I>, <I>Half A</I> (from ANSI sizes) or simply <I>Half Size</I>. Like the similar-sized ISO A5, it is used for everything from personal letter writing to official aeronautical maps. Organizers, notepads, and diaries also often use this size of paper; thus 3-ring binders are also available in this size. Booklets of this size are created using word processing tools with landscape printing in two columns on letter paper which are then cut or folded into the final size.
</P><P>Curiously, a foot-long sheet with the common width of Letter and (Government) Legal, i.e. <SPAN class="frac nowrap">8<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>2</SUB></SPAN> in × 12 in (220 mm × 300 mm), would have an aspect ratio very close to the square root of two as used by international paper sizes and would actually almost exactly match <A href="https://en.wikipedia.org/wiki/ISO_217" title="ISO 217">ISO RA4</A> (215 mm × 305 mm). This size is sometimes known as <I>European Fanfold</I>.<SUP id="cite_ref-PWG_17-4" class="reference"><A href="#cite_note-PWG-17">[17]</A></SUP>

<P>In 1996, the <A href="https://en.wikipedia.org/wiki/American_National_Standards_Institute" title="American National Standards Institute">American National Standards Institute</A> adopted <A href="https://en.wikipedia.org/wiki/ANSI/ASME_Y14.1" title="ANSI/ASME Y14.1">ANSI/ASME Y14.1</A> which defined a regular series of paper sizes based upon the <I>de facto</I> standard <SPAN class="frac nowrap">8<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>2</SUB></SPAN> in × 11 in (220 mm × 280 mm) Letter size which it assigned "ANSI A", intended for technical drawings, hence sometimes labeled "Engineering". 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 and therefore also includes Ledger/Tabloid<SUP id="cite_ref-PPD_18-1" class="reference"><A href="#cite_note-PPD-18">[18]</A></SUP> as "ANSI B". Unlike the ISO standard, however, the arbitrary base sides forces this series to have two alternating aspect ratios. For example, ANSI A is less elongated than A4, while ANSI B is more elongated than A3.
</P><P>The Canadian standard CAN2 9.60-M76 and its successor CAN/CGSB 9.60-94 "Paper Sizes for Correspondence" specified paper sizes P1 through P6, which are the ANSI paper sizes rounded to the nearest 5 mm.<SUP id="cite_ref-24" class="reference"><A href="#cite_note-24">[24]</A></SUP> All custom Canadian paper size standards were withdrawn in 2012 and  the respective ISO standards took their places.<SUP id="cite_ref-CAN_25-0" class="reference"><A href="#cite_note-CAN-25">[25]</A></SUP>
</P><P>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.

<P>Other, informal, larger sizes continuing the alphabetic series illustrated above exist, but they are not part of the series <I>per se</I>, because they do not exhibit the same aspect ratios. For example, Engineering F size is 28 in × 40 in or 711 mm × 1,016 mm with ca. 1.4286:1; it is commonly required for <A href="https://en.wikipedia.org/wiki/Naval_Facilities_Engineering_Command" title="Naval Facilities Engineering Command">NAVFAC</A> drawings, but is generally less commonly used. Engineering G size is <SPAN class="frac nowrap">22<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>2</SUB></SPAN> in (572 mm) high, but it is a roll format with a variable width up to 90 in (2.3 m) in increments of <SPAN class="frac nowrap">8<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>2</SUB></SPAN> in (216 mm). Engineering H through N sizes are also roll formats.
</P><P>Such huge sheets were at one time used for full-scale layouts of aircraft parts, automotive parts, wiring harnesses and the like, but are slowly being phased out, due to widespread use of <A href="https://en.wikipedia.org/wiki/Computer-aided_design" title="Computer-aided design">computer-aided design</A> (CAD) and <A href="https://en.wikipedia.org/wiki/Computer-aided_manufacturing" title="Computer-aided manufacturing">computer-aided manufacturing</A> (CAM). Some visual arts fields also continue to use these paper formats for large-scale printouts, such as for displaying digitally painted character renderings at life-size as references for makeup artists and costume designers, or to provide an immersive landscape reference.

<P>In addition to the system as listed above, there is a corresponding series of paper sizes used for <A href="https://en.wikipedia.org/wiki/Architecture" title="Architecture">architectural</A> purposes defined in  the same standard, ANSI/ASME Y14.1, which is usually abbreviated "Arch". This series also shares the property that bisecting each size produces two of the size below, with alternating aspect ratios. 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.
</P><P>The size Arch E1 has a different aspect ratio because it derives from adding 6 inches to each side of Arch D or subtracting the same amount from Arch E. Printer manufacturer recognize it as <I>wide format</I>.<SUP id="cite_ref-PWG_17-5" class="reference"><A href="#cite_note-PWG-17">[17]</A></SUP> An intermediate size between Arch C and D with a long side of 30 inches (760 mm) does not exist.

Often there is a pad of <A href="https://en.wikipedia.org/wiki/Paperboard" title="Paperboard">cardboard</A> (also known as paperboard or greyboard) at the bottom of the stack. Such a tablet serves as a portable writing surface, and the sheets often have lines printed on them, usually in <A href="https://en.wikipedia.org/wiki/Non-photo_blue" title="Non-photo blue">non-repro blue</A>, 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 "<A href="https://en.wikipedia.org/wiki/Post-It" class="mw-redirect" title="Post-It">Post-It</A>" or "Stick-Em" and available in various sizes, serve as a sort of tablet.

<P>This implies that all postcards have an aspect ratio in the range from 20∶17 = 1.18 to 12∶7 = 1.71, but the machinable aspect ratio is further restricted to a minimum of 1.30.
The only ISO 216 size in the US post card range is A6.
The theoretical maximum aspect ratio for enveloped letters is 23∶7 = 3.29, but is explicitly limited to 2.50.

Grain is important because paper will crack if folded across the grain: for example, if a sheet 17 × 11 inches is to be folded to divide the sheet into two 8.5 × 11 halves, then the grain will be along the 11-inch side.<SUP id="cite_ref-xerox-grain_30-0" class="reference"><A href="#cite_note-xerox-grain-30">[30]</A></SUP> Paper intended to be fed into a machine that will bend the paper around rollers, such as a <A href="https://en.wikipedia.org/wiki/Printing_press" title="Printing press">printing press</A>, <A href="https://en.wikipedia.org/wiki/Photocopier" title="Photocopier">photocopier</A> or <A href="https://en.wikipedia.org/wiki/Typewriter" title="Typewriter">typewriter</A>, should be fed grain edge first so that the axis of the rollers is along the grain.

<P>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 × ​<SPAN class="frac nowrap">6<SPAN class="visualhide"> </SPAN><SUP>1</SUP>⁄<SUB>4</SUB></SPAN> inches. Royal sizes were used for posters and billboards.
