International paper size standard

Columns A, B, and C 216 CERTIFICATEOf the finished dimensions of the paper defined byInternational standard.GermanyIndustrial standards DIN It is based on 476 and is used all over the world.The finished size is the size of the finished paper such as a notebook or copy paper.

For row A, the original size is "A0", the one that is halved on the long side is called "A1", and the one that is halved from A1 is called "A2". By halving the sides, the aspect ratio (Silver rectangle) Is the same (that is,similar) Is designed to be.However, since the standard size is rounded down when a fraction less than 1 mm appears, if the size is increased by simply doubling the short side by back calculation, an error will occur in the standard size value.In Japan, "A1" is sometimes called "A all" and "A0" is sometimes called "A times".

Column A

Column B

The side length of B0 is.

The size of column B is geometrically divided between column A and column A, which is one smaller.In other words, all adjacent area ratios of B1: A0: B0: A1: ...≒ 1.414, side length ratio≒ 1.189.This is because the area ratio of A0: A1: A2:… in column A is 2, and the side length ratio isIt is consistent with the idea that has become.It has the advantage that the magnification of A4 → B4 and the magnification of B5 → A4 are the same 1.189 times when making a copy.

BnThe rounded size (long side) of the size is obtained by the following formula.The short side isnCan be obtained by increasing.Is the floor function.

In some countries such as Japan, it is not the above column B, butJIS B columnIs commonly used.The international standard B column and JIS B column have the same name but different dimensions, so care must be taken not to confuse them.

Column C

269 CERTIFICATEIn column C, column C is standardized. Column C divides the geometric progression between column B (ISO) and column A.In other words, the adjacent area ratio of B0: C0: A0 is≒ 1.189, side length ratio≒ 1.091.

Column C is mainly used for envelopes. The C4 size (same as the Japanese square No. 20) is one size larger than the A4, so you can insert the A4 as it is without folding it. When sending A4 folds, select C5 size (same as Japanese square No. 6).

RA and SRA columns

The RA and SRA columns are international standards for base paper dimensions defined by.What is the base paper size? When printing, the edges of the paper are gripped by the claws of the machine, or when cutting.DragonflyWith the necessary margin added to, it is slightly larger than the finished size. The RA and SRA columns correspond to the A columns with the same number.

Column D is geometrically divided between column B and column A, which is one larger, and the area ratio of D1: B0: C0: A0: D0: B1:… isWill be. The area ratio of D0: F0: B0: G0: C0: E0: A0 is the area ratio of E column, F column, and G column., Side length ratio≈1.044 (there is no standard for geometric progression between A0 and D1).

JIS (Japan)

Japan OfJIS P 0138 "Paper processing finish dimensions"1951With the standard established in1929ToMinistry of Commerce Japanese standardIt is based on the "Paper Finishing Dimensions" announced as No. 92.It should be noted that1940"Paper finish dimensions"Extraordinary Japanese standardIt was also enacted as No. 138, and JIS P 0138 inherits this number from the standard number.

Column A is defined as "ISO-A series" and column B is defined as "JIS-B series". Column A is exactly the same as ISO, but column B is a local standard with different dimensions from ISO and is not compatible with international standards. Most of JIS B columnsJapan-Chugoku-TaiwanIt is used only in the three areas of.Edo PeriodIs the official paper ofMino paperIt is derived from the Mino format, which was determined based on.

The area of ​​JIS B0 is 1.5m2That is, the side length isIs.This is 0% larger than the original B3.

The long side of column B is that of column AdiagonalEqual to, and the short side equals the diagonal of column A, which is one less.

The similarity ratio of ISO columns B and A is≒ 1.189, while the size of JIS B column is A column≒ 1.225 times, A column is one smaller than JIS B column≒ 1.155 times.

The photo printing paper is 508 mm x 610 mm (20)inIt is often cut out from the base paper of × 24 in).Therefore, the number of divisions such as XNUMX-cut and XNUMX-cut is added to the name.In English, it is written in inches.It is different from the canvas size in art.

In recent years, with the spread of photo printers, photographic printer paper of a size based on this has been made, but A and B sizes are often used for compatibility with business applications.In addition, the Nobi size peculiar to this field so that the 35: 2 dimensional ratio of a traditional camera (3mm film digital SLR) can be output without trimming (cutting) as much as possible while making the best use of the output width of A / B size. Paper is also used.

  • International format --Approximately standard dimensions.Region andNewspaper companyThere are differences depending on.Globally, there is an initiative called "Web cut down" to redesign the paper layout so that it can be printed on narrow roll paper, which is cheaper than before, with the aim of reducing the size of the paper and issuing costs. Some newspapers are advancing, and even in the broad sheet format, the left and right dimensions are as narrow as the tabloid format.
