Paper size is 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 formats, ISO 216, is based on the metric system and is based on a sheet of paper having an area of 1 m² (Size A0). All ISO paper sizes have the same aspect ratio, which is the square root of two, which is approximately 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 - an area of 1 m² for the maximum sheet of the series is taken as the base.
- B - the length of 1 m for the short side of the maximum sheet of the series is taken as the base.
- C - envelope formats for sheets of series A (the sizes are approximately 9% larger).
The area and dimensions of the sides of format B are the geometric mean between the corresponding parameters of adjacent formats A, and the area and dimensions of the sides of format C are the geometric mean between the corresponding adjacent formats B and A.
The most widely known ISO standard format is A4. In Russia, formats from A4 to A1 are standardized for technical documentation (drawings, diagrams, texts, diagrams) (with rules for folding to A4 for storage). A3 format is the second most commonly used standard newspaper size, after A2.
In addition, technical documents use formats with a large aspect ratio, formed by repeatedly applying one of the standard formats along the long side of the sheet. For example, for series A you can create the following additional formats:
| A0 841x1189 mm |
A0x2 1682x1189 mm |
A0x3 2523x1189 mm |
A0x4 3364x1189 mm |
A0x5 4204x1189 mm |
A0x6 5045x1189 mm |
| A1 594x841 mm |
A1x3 1784x841 mm |
A1x4 2378x841 mm |
A1x5 2973x841 mm |
A1x6 3568x841 mm |
|
| A2 420x594 mm |

First of all, it should be noted that a paper size is a standardized size of a sheet of paper. Today, in different regions and countries of the world, there are several systems using completely different formats. However, only two dominate positions, namely: international, using the A4 standard and related formats, and North American.
The international system of standards, using paper format A3, A4, etc., is usually based on the metric system of measures. It comes from the sheet format, which has an area of 1 square meter - size A0. The height and length of such paper in the standard version are 1189 and 841 mm. respectively, and in inches this value is 46.8 and 33.1, respectively.
The international standard ISO 216, which has become widespread in many countries around the world these days, includes three series of formats. One of them is series A, the other two are B and C. The latter consists of envelope formats designed for sheets belonging to series A - the sizes in this case are approximately 7-8.5 percent larger. Next, you can familiarize yourself with the sizes of paper in several formats, in particular, you will find out the A3 size:
- So, if you have a question like “how much is a1 format?”, then you should say that the size of paper of this format in mm is 841 × 594, and in inches – 33.1 × 23.4.
- The height and length of the A2 format are 594 and 420 mm, respectively. To convert these values into more familiar centimeters, they need to be divided by 10.
- A3 paper size is 420x297 mm. This value translated into centimeters is equal to 4.2 × 2.97 cm. If we convert it into pixels for an image density of 300 dpi, then the A3 size will be equal to 4961 × 3508 pixels.
- The A4 format, which is widely used, has a height of 297 and a length of 210 mm. Half of an A4 sheet is equal to an A5 sheet, the size of which is 210x148. To verify this, it is enough to obtain the area of both sheets and compare it with each other: in the first case it is equal to 62370 mm2, and in the second – 31080 mm2. Next, divide the first value by the second and get an approximate ratio of 2 to 1, i.e. One A4 sheet can accommodate two A5 sheets.
- It should also be added that users often wonder what the 10x15 paper format is called. This sheet size is closest to the A6 format, the height of which is 148 mm and the length is 105 mm. – if you round both data values, you get approximately 10x15 cm. This type of paper is ideal for printing photographs that will later be stored in a photo album.
- If you are interested in formats related to the B series, for example, B2 paper size, then such a sheet has dimensions of 500x707 mm, which, in turn, is approximately 20 percent larger than an A2 sheet.
Whatman paper is also called Whatman paper (from English Whatman paper). This is paper with a weak texture, with surface sizing, due to which it has a high density. It wears off and ages very little, and therefore has a presentable appearance for quite a long time. The main, but not the only, area of application is drawing with pencils or watercolors.
History of creation
This miracle paper was first made in the 1750s in England by James Whatman, who was a paper manufacturer. He introduced into widespread use a new form for the production of paper, thanks to which sheets were obtained without traces of the grid, as was the case before. James called his creation “wove paper”. However, in our language, a completely different name has taken root - sheets of size from A1 and smaller began to be called Whatman paper, in honor of the inventor. But this is fundamentally wrong, since it is the technology by which the sheet of paper was made, and not its size.Spreading
Whatman paper very quickly found its admirers in the world of watercolor artists. At one time Gainsborough loved her very much.In Russia, this type of paper became widespread in the second half of the 19th century. It was used for printing engravings and lithographs. It was also used for drawing various drawings, which were made with pencils, watercolors or ink.
What sizes does Whatman paper come in?
Paper made using Whatman technology is called Ah. Its dimensions are determined according to international standards, making it the same size in all countries.The size of this paper format is based on a sheet called A0. It has an area equal to one square meter. The formats of the remaining sheets are obtained by dividing it in half with perfect accuracy.
A size paper sizes:
1. Size A0 – 841x1189 mm. This is a sheet, it is called Whatman paper in drawing.
2. Size A1 – 594x841 mm. This size was achieved by dividing an A0 sheet in half minus 1 mm, which is needed for the cut.
3. Size A2 – 420x594 mm. Traditional newspapers have taken this format as the basis for their pages.
4. Size A3 – 297x420mm. Format preferred by tabloid newspapers.
5. Size A4 – 210x297 mm. This is the most basic paper size that is used everywhere - in offices, for documents, for printers, etc.
6. Size A5 – 148x210 mm. This size is used mainly for small brochures and other handouts.
7. Size A6 – 105x148 mm. A very rare paper format.
As you can see, the social habit of calling A1 paper “Whatman paper” is erroneous. Whatman is not a format, but a manufacturing technology, and it is thanks to a wonderful man, James Whatman, that today we use convenient paper formats that occupy most of our work, and for some, our lives.

The paper size is the accepted standard of the paper sheet. The most common are international and North American standards. The A1 (also called Whatman paper) and A4 formats are international.
Instructions
A specialist in the field of engineering and mathematics, Walter Portsmann, proposed taking a sheet of 1 m² as a basis and calling it A0. All A sheets have the same aspect ratio of one to square of two.
Fold this sheet in half again and do the same. Now you have an A3 (297 × 420 mm) in your hands. This size sheet is often used by students for various drawings. If you repeat the previous step, you will get the A4 format you need, measuring 210 × 297 mm. This is the most common standard in Russia, used for various documents and printing. It turns out that the A1 format contains 8 A4 sheets.
Typically, these sizes are obtained from cut or folded paper, as well as specially made paper (for example, cards, invitations).

English paper formats
Note
These sizes do not apply to the formats of albums, atlases, toy books, booklets, facsimile, bibliophile, music editions, calendars, publications produced for export, publications printed abroad, as well as miniature, unique and experimental publications.
The format of publications is conventionally designated by the size of a sheet of paper for printing in centimeters and fractions of a sheet.
The shape of the publication in millimeters is determined: for an edition with a cover - by its dimensions after trimming on three sides, for an edition under a binding cover - by the dimensions of a block trimmed on three sides, with the first number indicating the width, and the second - the height of the publication.
Maximum formats are preferred for application. It is allowed to reduce the format of the publication to the minimum height and (or) width when printing the publication on machines of outdated designs, imported equipment, as well as taking into account the technological features of production.
Maximum deviations of publication formats from those established for a given circulation should not be more than 1 mm in the width and height of the block.
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 conveniently onto the sheet format.
This is understandable; a minimal amount of paper “waste” during 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 a printing house to print a non-format product, you will most likely have to overpay for paper that will end up in the trash, or, at best, recycled. This mainly applies to papers intended for digital and offset printing. But, for example, designer 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 main ones in the world. Understanding the difference in sizes, it will be much easier for you to communicate with printing house managers.
