Which size is larger than a4 or a5. Paper formats: international standards. Standard Envelope Sizes
The most common sizes of consumer and specialty paper are A4, A3 and A5. They are used for the following purposes:
- conducting business correspondence;
- preparation of drawings;
- preparation of design and technological documentation, diagrams and diagrams;
- drawing, creating layouts, etc.;
- print.
The principle of sheet size formation
The basis is the AO format, which has an area of 1 m2 and dimensions in cm of 118.9 x 84.1, and from it other basic and additional formats are installed. The remaining paper sizes are obtained by dividing by two. This is established in GOST 21.301-68 and the international standard ISO 216, which are used in Russia and other countries. The principle of formation is shown in Fig. 1:
AO (118.9x84.1) A2 (59.4x42.0) A4 (29.7x21.0) A5 (21.0x14.85) A5 (21.0x14.85) A3 (42.0x 29.7) A1 (84.1x59.4)

Fig. 1 - Formation of the most commonly used paper formats (sizes are indicated in centimeters)
A4 size in centimeters is 29.7 x 21.0. The second most commonly used size is A3 in cm, it has the following data - 29.7 x 42.0.
Types of paper
First of all, depending on the application, all industry-produced formats are divided into the following series:
- A – for documentation;
- B – for printing use;
- C – for envelopes.
Series A includes formats from A0 to A10 with sheet lengths in cm from 118.9 to 3.76 and widths from 84.1 to 2.6 cm.
Series B includes formats from B0 to B10 with sheet lengths in cm from 141.4 to 4.4 and widths from 100.0 to 3.1 cm. This standard is used in Canada and the USA.
The C series includes formats from C0 to C10 with sheet lengths in cm from 129.7 to 4.0 and widths from 97.1 to 2.8 cm.
The most used size for documents is A4 format, measuring 29.7 x 21.0 in centimeters.
Attention! In the age of computerization, the size of an image is judged by the file size in megabytes. The A4 sheet size is 33.2 MB (CMYK 300dpi).
Paper is also divided according to application. There are 10 groups:
- for printing, including self-copying and self-adhesive;
- decorative;
- for writing, drawing, typing and other similar works;
- packaging;
- electrical engineering;
- smoking;
- photosensitive;
- absorbent;
- base paper;
- industrial and technical.
Paper is also distinguished according to the following parameters:
- whiteness;
- density;
- color;
- transparency;
- type of surface (coated, matte, glossy, coated).
A4 size in cm, which is indicated above, is considered office paper, because... Most often used as a consumable material for copiers and printers, for business correspondence, production of catalogues, advertising materials, drawings.
- A1 (594841 mm): Used in professional layout and design;
- A2 (420594 mm.): A professional option for artistic works by masters from different fields of art. Used most often in printing houses for printing banners, by students for diploma and coursework. DPI lovers will also like this format: it is quite extensive and will fit harmoniously into the surroundings;
- A3 (297420 mm.): A4 sheet format increased by 2 times; optimal for professional student work assigned in educational institutions. Paintings, floristry, decorative panels, collages made in given size, look elegant, miniature, are a universal holiday gift
- A4 (210297 mm.): a universal option for creative people, especially children starting to learn to draw. The A4 sheet format is suitable for small sketches with ink, felt-tip pens, pencils, gel pen, as well as for printed materials. Widely and often used in printing houses.
Yes, indeed, these formats are not changing; they have a certain size, which is determined by international standards. This will be the case in Russia and Turkey, for example. Which is very convenient, because we use documents everywhere. They come from the A0 format (there is one). It has an area of one square meter. And everyone else divides it in half and they are already measured. This is the arithmetic.
A0 – 841?1189
A1 – 841x594
A2 – 420x594
A3 – 297x420
A4 – 210x297
Whatman sheet formats are determined according to the published and approved standard: GOST2.301-68
The main sizes of paper sheets produced at all factories in the country are:

Depending on the functional purpose, different kinds formats, sheets of paper can be treated with special components or have a unique structured surface, for example: watercolor paper, perforated paper, decorative colored paper, pastel paper. When working with oil art tools, thicker, moisture-resistant paper is used, most often canvases stretched on a stretcher.
a very convenient thing in this matter)) has already helped out several times))
In accordance with ISO standards, which are international, paper is divided into a number of series (A, B, C). Below is a table with these series, format and sizes.
As can be seen from the table, A series paper is mainly used for documents. To prepare documents in Russia, A4 paper is used.
Series B paper is typically used for printing products. And C series paper is used for envelopes.
Format A1 - 841cm by 594cm - this is the largest format, the so-called drawing paper, format A2 - 420cm by 594cm - this is a sheet of exactly half of whatman paper cut across, format A3 - 297cm by 420cm - this is again A2 format cut across, but A4 format – 210cm by 297cm is the most common paper format on which everything is usually printed and photocopied.
I used to get confused all the time, although I only use the A4 format; I need other formats to select passports or picture frames. Thanks to this drawing, everything became clear. I’m no longer confused. I hope it’s useful to you too.
The size of the A series formats (established by the International Standard for Paper Sizes, ISO 216, based on the metric system of measures, based on the format of a paper sheet having an area of 1 m - size A0).
format size: width x length (mm)
For technical documents, formats with a large aspect ratio are used, which are formed by repeatedly applying one of the standard formats along the long side of the sheet. For example, for Series A the following additional formats can be created.
I first encountered paper formats at the institute. Only then did I find out that the format called
A1 has a size of 841 by 594 millimeters,
A2 has a size of 420 by 594 millimeters,
A3 has a size of 297 by 594 millimeters,
but the most popular format, which is now in the office, in the store, and in the university, is A4. Its format measures 210 by 297 millimeters.
The largest format is A0 (841 mm by 1189 mm.)
Then - A2. A2 will have a size of 420 mm. by 594 mm.
After that it will be A3 format. A3 format has a size of 297 mm by 420 mm.
The smallest format is A4. And we see format 4 almost every day and use it during photocopiers.
A4 has a size of 210 mm by 297 mm.
I think my answer helped you.
Wish you luck.
A1, A2, A3, A4 are international formats indicating paper sizes.
The A1 format measures 841 millimeters by 594 millimeters;
A2 format measures 420 millimeters by 594 millimeters;
A3 format measures 297 millimeters by 594 millimeters;
The A4 format has a size of 210 millimeters by 297 millimeters (the most common format).

History of A4 sheet
Millions of office workers around the world process tons of paperwork every day. They use paper for copying, printing, faxing and preparing major contracts. All these documents are reproduced in different languages and have very different values. But they have one general characteristics– they are printed on paper of the same format.
All over the world, three generally accepted paper formats are now used, which are marked with Latin letters– A, B, C. Formats B and C are more suitable for creating envelopes, posters, calendars and posters. But paper size marked A is used in our lives every day, especially A4 format.
How did this happen and why? Is the appearance of a leaf of this size an accident, or is there some kind of pattern underlying it?
Of course, this is not an accident. Dimensions of this format papers in all its gradations from A1 to A10 are subject to a mathematical formula. According to the metric system of measures, a sheet of paper with an area of exactly 1 square meter is taken as a basis. or sheet A0. Next, the formula comes into force according to which the sides of the sheet are in relation to each other, like “1 to the root of 2.” This is simply an ideal formula, because further all the sizes of this format are exactly two times smaller than the previous one, but at the same time the proportions are preserved.
The need for paper of this particular format arose in the first decades of the twentieth century. This is due to the development of printing and printing. Previously, paper with the size of the so-called “golden ratio” was successfully used all over the world. It also had certain proportions, but only based on a mathematical formula derived by Pythagoras. This was relevant for the era when such dimensions were widely used by architects and painters. It embodied all the harmony and symmetry of the world around us. Its task was to attract attention to certain visual centers. But when it became necessary to fold a sheet of this format in half, it turned out to be inconvenient, and the pages looked ugly.
For the first time, it was the German engineer-mathematician, Doctor of Science Walter Porstmann who proposed standardizing paper sizes. It was German practicality and love of precision that formed the basis for the standardization of paper sizes, which is now widespread internationally. And so, since 1922, the A0 format became known to the world, which has dimensions equal to 841x1189 mm. All subsequent sizes are obtained by reducing the larger side by half and so on up to the A10 format, which has parameters of 26x37 mm.
Russia, like most European countries, uses the following paper formats: the most common is A, the less popular are B and C. Many do not know that in addition to these European formats there are others. This is North American standard and Japanese standard.
European formats
A-formats
A is the most popular format. It is used in a variety of industries. A-series sheets are used by every resident of Russia.
Size | A0 | A1 | A2 | A3 | A4 | A5 | A6 | A7 | A8 | A9 | A10 |
mm | 841×1189 | 594×841 | 420×594 | 297×420 | 210×297 | 148×210 | 105×148 | 74×105 | 52×74 | 37×52 | 26×37 |

In the Russian Federation, the most popular formats for documents, for creating drawings and diagrams are from A4 to A1.
Series B format
B-format paper sizes are larger than A-series sheets. Such media are used much less often, and in general, few people know that such a format exists.
Size | B0 | B1 | B2 | B3 | B4 | B5 | B6 | B7 | B8 | B9 | B10 |
mm | 1000×1414 | 707×1000 | 500×707 | 353×500 | 250×353 | 176×250 | 125×176 | 88×125 | 62×88 | 44×62 | 31×44 |
inches | 39.37 × 55.67 | 27.83 × 39.37 | 19.69 × 27.83 | 13.90 × 19.69 | 9.84 × 13.90 | 6.93 × 9.84 | 4.92 × 6.93 | 3.46 × 4.92 | 2.44 × 3.46 | 1.73 × 2.44 | 1.22 × 1.73 |
This format is used much less. Not everyone knows about its existence, because in many areas of life A-format sheets are more often used.
C formats
C-size paper is intended for making envelopes. Moreover, these envelopes are designed for A-format sheets.
Size | C0 | C1 | C2 | C3 | C4 | C5 | C6 | C7 | C8 | C9 | C10 |
mm | 917×1297 | 648×917 | 458×648 | 324×458 | 229×324 | 162×229 | 114×162 | 81×114 | 57×81 | 40×57 | 28×40 |
inches | 36.10 × 51.06 | 25.51 × 36.10 | 18.03 × 25.51 | 12.76 × 18.03 | 9.02 × 12.76 | 6.38 × 9.02 | 4.49 × 6.38 | 3.19 × 4.49 | 2.24 × 3.19 | 1.57 × 2.24 | 1.10 × 1.57 |
C size sheets are used to create envelopes for A4 paper.
So, you know all the varieties of European series that the international standard ISO 216 includes.
North American Standard Formats
The North American standard is common in the following countries: USA, Canada, Mexico, Philippines, as well as in several countries in South America. Sheet formats are determined by the American National Standards Institute (ANSI). The paper formats that the North American standard includes differ significantly from European sheets.
Popular name | ANSI classification | in mm | in inches | Aspect Ratio | Similar ISO format |
Letter | ANSI A | 216×279 | 8.5×11 | 1: 1,2941 | A4 (210 × 297) |
Legal | 216×356 | 8.5×14 | 1: 1,6471 | ||
Ledger or Tabloid | ANSI B | 432×279 | 17×11 | 1: 1,5455 | A3 (297 × 420) |
ANSI C | 432×559 | 17×22 | 1: 1,2941 | A2 (420 × 594) | |
ANSI D | 559×864 | 22×34 | 1: 1,5455 | A1 (594 × 841) | |
ANSI E | 864×1118 | 34×44 | 1: 1,2941 | A0 (841 × 1189) |
ANSI size A, also called “Letter” (21.6 by 27.9 cm), is used in North American countries as size A4. The A3 format almost completely corresponds to the ANSI B or “Ledger”, “Tabloid” format.
Size Compliance:
- ANSI C - A2
- ANSI D - A1
- ANSI E - A0
So, you have an idea about the paper standards of North American countries.
Japanese standard formats
Japan uses JIS (Japan Industrial Standards) sheets. This standard also includes the A and B series. The Japanese A format fully complies with the European ISO 216. B-series paper is one and a half times larger than its European counterparts.
Japanese standard B-series formats:
JIS series B | Shirokuban (四六判) | Kikuban (菊判) | |||||
Format | size, mm | Format | Japanese Name | size, mm | Format | Japanese Name | size, mm |
B0 | 1030×1456 | ||||||
B1 | 728×1030 | full sheet | 四六全判 | 788×1091 | full sheet | 菊全判 | 636×939 |
B2 | 515×728 | 1/2 | 四六半切 | 545×788 | 1/2 | 菊半切 | 469×636 |
B3 | 364×515 | 1/4 | 四六4切 | 394×545 | 1/4 | 菊4切 | 318×469 |
B4 | 257×364 | 1/8 | 四六8切 | 272×394 | 1/8 | 菊8切 | 234×318 |
B5 | 182×257 | 1/16 | 四六16切 | 197×272 | 1/16 | 菊16切 | 159×234 |
B6 | 128×182 | ||||||
B7 | 91×128 |
It is clearly shown: sheets of format B (Japanese standard) are much larger than the European B-series.
So, we talked about all the international standards that are used to determine paper sizes. Let us only note that most often the printer prints various documents on sheets in A4 format. This media size is the most popular, but others are also needed for less common purposes.
Popular formats. Dimensions in cm, mm, inches. Size table.
Summary tables with the sizes of sheets of paper in popular formats A, B, C in millimeters, centimeters and inches are presented on the pages:
General background information and technical features Paper sizes are listed below.
Formats A, B, C
IN modern world Three popular paper size formats are A, B, C (ISO 216 standard). The dimensions of sheets of these formats are taken into account in the manufacture of writing paper, paper for printers and faxes, envelopes, etc. Each format has a range of paper sheet sizes from 0 to 10 (standard sizes): A0-A10, B0-B10, C0-C10. Type size 0 specifies the largest sheet sizes, type size 10 is the smallest, that is, A1 is smaller than A0. If we compare the corresponding standard sizes of these formats with each other, then sheets of format A are the smallest, C - medium, B - largest. The dimensions for format C are obtained as the geometric mean of A and B, that is, the square root of the multiplication of dimensions A × B. Format C was created from the consideration that sheets of format A (document) fit into sheets of format C (envelope). Total: A0-A10< C0-C10 < B0-B10.
The aspect ratio of the sheet of each format with a certain degree of error is expressed as: 1: 1.4142. Each subsequent standard size of a sheet of paper within one format is half the size of the previous one: the height of the subsequent standard size is equal to the width of the previous one, the width of the next one is ½ the height of the previous one. For example, A5 is A4 folded in half, since [height of A5 = width of A4] and [width of A5 = ½ height of A4]. Thus, knowing the size of a sheet of any standard size, you can calculate the sizes of others without resorting to tables.
In accordance with the standard, the largest sheet is in B0 format (1000 × 1414 mm), the smallest sheet is in A10 format (26 × 37 mm), which is comparable to the size of a modern stamp. The most common format in everyday life is A4.
Errors
ISO 216 defines the permissible errors in paper dimensions during production:
- ±1.5 mm (0.06 inch) for sheets with sides not exceeding 150 mm (5.9 inch)
- ±2 mm (0.08 inch) for sheets with sides from 150 to 600 mm (5.9 to 23.6 inch)
- ±3 mm (0.12 in) for sheets with sides greater than 600 mm (23.6 in)
Other formats
In addition to formats A, B, C, there are paper formats 2A0, 4A0, A3+, RA, SRA, C7/6, DL and others.
Formats 2A0 and 4A0 are not described in the ISO 216 standard, but are in the DIN 476 standard (Germany). Formats 2A0 and 4A0 define sheets larger than A0. The table shows the dimensions.
The A3+ format is known, the dimensions of which are not described in the ISO 216 standard. The format is often used in printing. Its dimensions are 329 × 483 mm or 12.9 × 19 inches. The aspect ratio is 1:1.468, which is different from the standard 1:1.4142
There are rarely used formats, we list them: A2 Extra, A3 Extra, A3 Super, Super A3, A4 Extra, A4 Super, Super A4, A4 Long, F4, SO B5 Extra, A5 Extra and others.
In industry and printing, the following formats are used: RA (0-4), SRA (0-4), C7/6, DL.
