What are the common dimensions of graphic design?

The format size stipulated by the state is an international standard series, which has been incorporated into the national industry standard GB/T 1999 and implemented nationwide. At present, the format specifications of books and periodicals are mainly series specifications, as follows:

a4( 16k)297mm×2 10mm；

a5(32k)2 10mm× 148mm；

a6(64k) 144mm× 105mm；

a3(8k)420mm×297mm；

Note: A3(8k) size has not been determined, but it has been widely used.

When we talk about A4 copy paper in our daily life, 8K paper refers to these sizes, that is, the size of A4 paper (16K paper) is 297mm×2 10mm, and the size of 32K notebook (A5 notebook) is 21cm×14.8cm.. ..

Paper size introduction:

The size of a2 paper (a4 size) is 594 mm× 420 mm.

A3 Paper size (8 sizes) 420mm× 297mm

A4 paper size (16 width) 297mm×2 10mm.

B4 Paper size (16)

B5 Paper size (32 sheets)

8 opening size

Paper can be divided into newsprint, letterpress, offset paper, glossy paper, matt paper, bible paper, map paper, gravure paper, weekly newspaper, pictorial paper, whiteboard paper, writing paper and special paper.

Ordinary paper can be divided into 60gsm, 80gsm, 100gsm, 105gsm, 120gsm, 157gsm, 200gsm, 250gsm, 300gsm, 350gsm and 400gsm by weight.

8 is 8, and the size is 390 x 270 mm If it is not in word, set it yourself.

Open it completely, load 8 sheets, and you measure it.

The specification of paper refers to that after the paper is made, it is trimmed and cut into a certain size. In the past, the paper size was expressed by the number of "open" (such as 8 open or 16 open, etc.). ). Now I adopt the international standard, and stipulate that the format specifications of paper are expressed by A0, A 1, A2, B 1, B2, etc ... The standard stipulates that the proportional relationship between the width (expressed by X) and the length (expressed by Y) of paper is X: Y =1:N. ..

According to the basic area of paper format, the format specifications are divided into A series, B series and C series, and the format size of A0 is 84 1mm? 189mm, width1m2; The width of B0 is 1000mm? 4 14mm with a width of 2.5 square meters; Is the width dimension of C0 917mm? 279mm, width area of 2.25 square meters; The format specification of copy paper only adopts A series and B series. If A0 paper is split in half along the length direction, it becomes A 1 specification; If A 1 paper is split along the length direction, it becomes A2 specification, and so on, it becomes A8 specification; B8 paper is also split into B8 standard in this way. The format sizes of A0 ~ A8 and B0 ~ B8 are shown in the following table. Among them, seven format specifications such as A3, A4, A5, A6, B4, B5 and B6 are commonly used specifications for copy paper.

For example, "A4" paper is a type A basic size paper folded four times, so the area of an A4 paper is a quarter of the area of the basic paper, that is,116. The rest and so on.

I never thought about the size when I made pictures before. I have always felt that it is difficult to convert pixels into basic units such as millimeters and centimeters, and the resolution should be considered. Last time, I confidently made a resume cover, and the picture was very effective, but it was blurred and ugly when printed on A4 paper. Today, I specially studied this problem, which is actually not difficult. The analysis is as follows:

The size of A4 paper is 2 10mm*297mm, that is, 2 1.0cm*29.7cm, and when 1 inch =2.54cm and the resolution is 72pixels/inch, we convert it into pixels /cm, that is, 28.3. Now, when we make a picture, we convert it into pixels (2655

Similarly, we can get:

When the resolution is 300 pixels/inch, A4 size is 2479 * 3508; (pixels)

When the resolution is 120 pixels/inch, the size of A4 is 1487*2 105. (pixels)

So if you want to print a picture, you'd better convert it first, otherwise the picture quality is likely to decrease! Generally speaking, if it is printed matter, it is best to use 300 pixels/inch, and if it is printer or inkjet, you can choose a resolution of 72 pixels/inch.

A0= 1 189*84 1

A 1=84 1*594

A2=594*420

A3=420*297

A4 specification: 2 10*297

The unit is millimeters.

Positive degree 16 (185x260)

Generosity 16 (2 10x285)

What is the unit of "openness"?

Open as much paper as possible.

For example, 16K means all 16 sheets and two sheets in folio.

How big is the first drive?

Full opening positive degree: 780 x 1080.

Generosity: 880 x 1 180

Printing paper specification

The so-called opening number means cutting into several parts. For example, an 8-size piece of paper is 1/8 (cut three times). Before designing, the paper size should be selected first, because the printing machine can only use several kinds of paper (generally fully open and fully open), and then cut it into the required size by the machine after printing once, so don't use special specifications other than the following table if it's all right, so as to avoid paper printing dissatisfaction and waste of space.

Because the machine grabs the paper and moves it, the edge of the paper cannot be printed, so the original size of the paper will be larger than the actual size, and the blank part of the edge will be cut off after printing, so there will be a difference between the full size and the cut size. If the poster is intentionally left blank, you can choose not to cut it.
