Paper sizes

Do you have to calculate paper size? Here you will find a calculator that will allow you to know the measurements of the main papers (Series A, Series B and Series C) in different units (meters, cm, mm, inches and more).

You don't have to look any further what is the size of an A4, A3, A5 or any other paper. We provide you with the dimensions of the papers that are defined in the ISO 216 standard and the DIN 476 standard in which the standard paper dimensions are specified.

A Series Paper

Below you will find a table with the main ones. measurements of all Series A papers among which you can find sizes such as DIN A4 among others:

SizeWidth x Height (mm)Width x Height (inches)
4A01682 x 2378 mm66.2 x 93.6 in.
2A01189 x 1682 mm46.8 x 66.2 in.
A0841 x 1189 mm33.1 x 46.8 in.
A1594 x 841 mm23.4 x 33.1 in.
A2420 x 594 mm16.5 x 23.4 in.
A3297 x 420 mm11.7 x 16.5 in.
A4210 x 297 mm8.3 x 11.7 in.
A5148 x 210 mm5.8 x 8.3 in.
A6105 x 148 mm4.1 x 5.8 in.
A774 x 105 mm2.9 x 4.1 in.
A852 x 74 mm2.0 x 2.9 in.
A937 x 52 mm1.5 x 2.0 in.
A1026 x 37 mm1.0 x 1.5 in.

As you can see, the largest paper in the A series is DIN A0. which has an area of one square meter. As we reduce its surface by half (approximately), we obtain the rest of the paper types such as DIN A1, A2, A3, A4 and so on.

Please note that the above explanation involves a rounding of the figures and that DIN A0 actually has an area of 0.999949 m (0.999949 ft).2

A4 size

The DIN A4 is the traditional sheet of paper and has a size of 210 x 297 millimeters.. Below you have a table in which you can see the measurements in other units:

A4 size
Millimeters210 x 297 mm
Centimeters21 x 29.7 cm
Meters0.210 x 0.297 m
Inches8,268 x 11,693 in.

Undoubtedly, this is the most widely used paper format is present in our daily lives on a constant basis. If you have a printer at home, it is sure to be powered by foils so here you can buy them at a good price.

A3 size

DIN A3 is approximately twice the size of A4 (in some places it is called a double sheet) and has dimensions of 42 cm x 29,7 cm.

Except for occasional printing, A3 is not a common format in the domestic sector, although it is easily found in stationery stores with different grammages starting at 160gr/m².2 are already beginning to be considered as cardboard, which in addition to are usually available in a wide variety of colors.

Below you have a A3 size table in the most common units:

A3 sizes
Millimeters297 x 420 mm
Centimeters29.7 x 42 cm
Meters0.297 x 0.42 m
Inches11,693 x 16,535 in.

If you want to buy papers of this size, you can do it here.

A5 size

The DIN A5 paper is a format known as a pastern and has a size of 21 cm x 14.8 cm..

Its use is varied and we can find it in brochures, flyers, invitations, notepads, etc. If you want to buy this type of paper, here you can do it.

Dimensions A5
Millimeters148 x 210 mm
Centimeters14.8 x 21 cm
Meters0.148 x 0.21 m
Inches5,827 x 8,268 in.

A2 size

A2 paper is too large for home use because it is too small.Its size is 59.4 cm x 42 cm.However, it is one of the first options to consider for small signage.

Precisely because they are used in signage, the options of thickness and finishes are beginning to be very varied, being able to find them with matte finish, satin finish, photographic finish, etc.

Below is a table summarizing the DIN A2 size in different units:

Measures A2
Millimeters420 x 594 mm
Centimeters42 x 59.4 cm
Meters0.42 x 0.594 m
Inches16,535 x 23,388 in.

And if you want, here you can find A2 papers at a very good price.

A1 Size

Measuring 84.1 cm x 59.4 cm, DIN A1 paper is used in signage and is also available in multiple weights and finishes, as is the case with A2.

Because of its large dimensions, it is necessary to use professional printing equipment that can handle such large paper. Here you can buy DIN A1 brackets.

As in the other cases, we also leave you with a table in which you can see the size of the A1 in different units in case it makes your work easier:

Dimensions A1
Millimeters594 x 841 mm
Centimeters59.4 x 84.1 cm
Meters0,594 x 0,841 m
Inches23.388 x 33.11 in.

A6 size

We end our review of the most commonly used A Series papers with DIN A6, whose dimensions are 14.8 cm x 10.5 cm.

Due to its size, it is an ideal paper for flyers, advertisements, invitations, etc. Below you can see its measurements in more units:

Measurements A6
Millimeters105 x 148 mm
Centimeters10.5 x 14.8 cm

Inches4,134 x 5,827 in.

And here you can find DIN A6 papers at a good price.

B Series Paper

The B series of paper is also defined by ISO 216 and is less common at the domestic level than DIN A. The dimensions of Series B papers are halfway between Series A and Series B. and is often used for books, envelopes or documents such as passports. However, on an industrial level, DIN B is quite common in magazines and newspapers.

The largest format of the B series is DIN B0 with a surface area of √2 m². and has dimensions of 1.414 x 1 meter. Below you have a table with the dimensions of the rest of the supports available in the B series:

DIN BWidth x Height (mm)Width x Height (inches)

B944 x 62 mm1.7 x 2.4 in.
B1031 x 44 mm1.2 x 1.7 in.

C Series Paper

The role of the C series is used exclusively for envelopes. Its classification is the same as in the A series, so that a C5 envelope fits an A5 size sheet and so on.

Below is a table showing all envelope sizes which are in accordance with ISO 216 of the C series:

DIN CWidth x Height (mm)Width x Height (inches)
C0917 x 1297 mm36.1 x 51.5 in.

How to make an envelope from a sheet of paper

If you need an envelope but don't have one on hand, you can make your own from a sheet of paper. You simply have to follow the instructions in the video, since explaining it in written form is much more difficult to understand.

Paper size in pixels

If you want to know the size of a paper in pixels, use our calculator to calculate the centimeters to pixels. There you can type the dimensions you want and convert it to px according to the number of dots per inch you need.

We hope that with our information you already have a clear idea of what are all the paper sizes that exist in the A, B and C series. If you have any questions or problems, please do not hesitate to ask us.
