ISO 216 A paper sizes are shown in the table below in millimeters and inches (values ​​can be converted to cm by dividing mm by 10). The A series paper size picture on the right provides a visual explanation of how the sizes relate to each other - for example, A5 is half A4 and A2 is half the size of A1.

Sizes of A-size sheets

* - resolution of A format is given for an image density of 300 dpi (pixels per inch).

For paper sizes in centimeters, convert mm to cm by dividing by 10, to convert inches to feet, divide inch by 12.

4A0 and 2A0 - DIN 476 high size formats

There are also paper sizes larger than A0 - these are 4A0 and 2A0. These sizes are not described in the ISO 216 standard, but are commonly used for large paper sizes. The origin of these formats comes from the German DIN 476 standard, on the basis of which ISO 216 was created.

Size A paper size tolerances and errors

ISO 216 allows for errors in the production of A-size paper up to the following values:
• ± 1.5 mm (0.06 in.) For sizes up to 150 mm (5.9 in.)
• ± 2 mm (0.08 in.) For sizes ranging from 150 to 600 mm (5.9 to 23.6 in.)
• ± 3 mm (0.12 in.) For any dimension above 600 mm (23.6 in.)

Format series A characteristics and properties

ISO 216 characterizes a given paper size with the following parameters:
• Length divided by sheet width equals 1.4142
• Each subsequent dimension A (N) is defined as A (N-1) cut in half parallel to its short side.
• The A0 format has an area of ​​1 square meter.
• The standard length and width of each size is rounded to the nearest millimeter.

Note: the last point is there, because the square root of 2 in the aspect ratio does not always give whole numbers.

International implementation and use of sheet format

A-size paper sizes are currently used widely around the world, except in the United States, Canada, and parts of Mexico. A4 has become the standard business letter size in English-speaking countries such as Australia, New Zealand and the United Kingdom, which are accustomed to using the imperial number system everywhere. In Europe, paper sizes were adopted as the formal standard in the mid-20th century, and from there they spread throughout the world.

Sizes of A-size and series paper sheets was last modified: November 2nd, 2016 by admin

Most of the standard printing products are printed in standard formats: A6, A5, A4, A3, A2, DL "euro format" - 99x210 mm (1/3 A4) or in sizes that fit comfortably on the sheet format.

This is understandable, the minimum amount of paper "waste" when printing is beneficial to everyone: manufacturers of printing equipment, paper manufacturers, printing houses and printing centers. Therefore, when developing a layout, this point must be taken into account.

If you offer the printing house to print a non-formatted product, most likely you will have to overpay for paper that ends up in the trash, and at best for recycling. This mainly applies to papers that are intended for digital and offset printing. But, for example, design cardboards and papers have a size in most cases of 700x1000 mm (approximately B1 format 707x1000mm). When printing on such papers, you need to be more careful about the size of the product, since the cost of such materials is orders of magnitude higher.
I will try to describe as briefly but informatively as possible printed sheet format series A, as one of the major in the world. By understanding the difference in size, it will be much easier for you to communicate with print managers.

SRA3 sheet format

Predominantly, digital printing presses have a basic size of printed sheet SRA3- 320x450 mm. The maximum and optimal size of this size will include such products (taking into account the edge under the edge of 2mm per side)

Paper is one of the few materials that has come down to us since ancient times. Today we will talk about paper from the "A" line. You will find out the dimensions of the A0 format in cm, its characteristics. And besides that, you can learn some pretty useful details about paper in general.

Quality

Before choosing the parameters of the workspace (in this case, a paper sheet), you need to decide on its quality. Nowadays, stationery stores offer a wide selection of paper for creating drawings, drawing with paints and pencils, for taking notes, etc. But all of these types can be divided into three categories:

Newspaper material. Cheap and cheerful, but suitable for a huge circulation. It is often used to make children's notebooks and cheap exercise books.

Offset option. She's an office one. The A0 paper size falls into this category, although it is rarely seen in offices.

Coated sheet. The most expensive, often used for high quality products in small quantities.

Format, aspect ratio and more

The size of the A0 sheet format in centimeters is 84.1 * 118.9 centimeters. But we do not live in a perfect world, so any product has an error or inaccuracy. This also applies to A0 in mm. For paper "A", the ISO 216 standard from 1975 is used, which gives manufacturers the opportunity to deviate slightly from strict norms.

For paper size A0, which is in the uppermost range (products over 600 millimeters), an error of three millimeters is allowed.

For drawing, this figure is not critical, and in the case of industrial use, all products are pre-checked. This is especially important when creating a drawing with the size A0 in cm. It is with the size A0 that the concept of "Whatman" is associated, which is often mistakenly applied to the A1 format.

Why is this happening and what is the general format for creating a paper sheet "A"? What are the benefits?

One, affordable and proven measurement system. All measurements are carried out in millimeters, so an ordinary client has the opportunity to independently double-check the dimensions of the A0 format in mm if he suspects the wrong size. Millimeters are rather small designations, but you can measure them with a regular ruler, which is in every home.

Calculation of proportions. By multiplying the length of the short side by a factor of 1.4142, you get the long side. And it doesn't matter if the size of Whatman A0 is in centimeters, millimeters or meters. And it doesn't matter if A0, A1 or another "A" sheet - the area changes, but the proportions remain the same.

A ready-made formula for calculating smaller formats based on large ones on their sides. To get the parameters of any sheet A, you need to cut sheet A-1 in half. Make sure that the cutting lines run exactly parallel to the width of the sheet. By the way, if you are too lazy, there is no time and desire, to bother with measurements and calculations - just open the table with paper sizes. It contains not only the size in mm, cm, but also in pixels, and all the data is exactly equal to the standards. Note that plates often indicate inches instead of pixels or cm.

Finally…

The format and dimensional grid of paper is a fairly simple "science", although it has a lot of various pitfalls. The main thing is that you you need to know - this series of paper sheet and its designation... Then you can contact any stationery store or printing house, and they will help you to choose or select the necessary material. In general, whatman paper is an excellent material for creating large posters for support groups, colorful announcements, it will be an excellent tool for creating a large portrait or composition.

size table

Russia, like most European countries, uses the following paper formats: the most common is A, the less popular B and C. Many do not know that besides these European formats, there are others. This is the North American standard and the Japanese standard.

European formats

A-formats

A is the most popular format. It is used in a wide variety of industries. A-series sheets are used by every resident of Russia.

In the Russian Federation, the most popular formats for documents, for creating drawings and diagrams - from A4 to A1.

B series format

B-size paper sizes are larger than A-series sheets. Such media are much less frequently used, and in general, few people know that such a format exists.

This format is much less used. Not everyone knows about its existence, because in many areas of life they often use A-format sheets.

C formats

C-size paper is used for making envelopes. Moreover, these envelopes are designed for A-format sheets.

C-size sheets are used to create A4 envelopes.

So, you know all the varieties of the European series that the international standard ISO 216 includes.

North American Standard Formats

The North American standard is widespread in such countries: USA, Canada, Mexico, Philippines, as well as in several states of South America. Sheet formats are defined by the American National Standards Institute (ANSI). Paper sizes that include the North American standard differ significantly from European sheets.

ANSI A size, also called "Letter" (21.6 x 27.9 cm) is used in North American states as A4 size. The A3 format almost completely corresponds to the ANSI B format or "Ledger", "Tabloid".

Correspondence of sizes:

• ANSI C - A2
• ANSI D - A1
• ANSI E - A0

So, you have an idea of ​​the paper standards of the North American countries.

Japanese standard formats

Japan uses JIS (Japan Industrial Standards) sheets. This standard also includes the A and B series. Japanese A format fully complies with European ISO 216. B-series paper is one and a half times larger than European counterparts.

Japanese B-series formats:

It is clearly shown: sheets of the B format (Japanese standard) are much larger than the European B-series.

So, we talked about all the international standards that are used to define paper sizes. We only note that most often a variety of documents are printed on sheets in A4 format on a printer. This size of print media is most in demand, but others are also needed for less common purposes.

Paper Size - The standardized size of a paper sheet. Different countries have adopted different formats as standard at different times. Currently, two systems dominate: the international standard (A4 and related) and the North American one.

The international standard for paper sizes, ISO 216, is based on the metric system and is based on a paper sheet format that has an area of ​​1 m² (Size A0). All ISO paper sizes have the same aspect ratio equal to the square root of two, which is roughly 1: 1.4142. The standard has been adopted by all countries except the United States and Canada. In Mexico and the Philippines, despite the adoption of an international standard, the American letter format is still widely used.
Consists of three series of formats (with similar sizes for the same numbers):

• A - the base is taken as an area of ​​1 m² for the maximum sheet of the series.
• B - the base is taken as a length of 1 m for the short side of the maximum sheet of the series.
• C - Envelope sizes for Series A sheets (about 9% larger).

The area and dimensions of the B format sides are the geometric mean between the corresponding parameters of the adjacent A formats, and the area and dimensions of the C format sides are the geometric mean between the respective neighboring B and A formats.

The most widely known ISO standard format is A4. In Russia, for technical documentation (drawings, diagrams, texts, diagrams) formats are standardized from A4 to A1 (with folding rules up to A4 for storage). A3 format is the second most used, after A2, the standard newspaper size.

In addition, technical documents use formats with a large aspect ratio, formed by repeatedly applying one of the standard sizes along the long side of the sheet. For example, for Series A, the following additional formats can be generated:
