Kneel and beg how big the B3 paper is and B5 paper

Commonly used paper can be divided into two categories: A and B according to size:

Class A is what we usually call large paper, the size of the whole paper is 889 * 1194mm, can be cut A1 (large folio, 570 * 840mm), A2 (large four open, 420 * 570mm), A3 (large eight open, 285 * 420mm), A4 (large sixteen open, 210 * 285mm), A5 (large thirty-two open, class B is what we usually call positive paper, the size of the whole paper is 787 * 1092mm, can be cut B1 (front folio, 520* 740mm), B2 (4 open, 370 * 520mm), B3 (8 open, 260 * 370mm), B4 (16 open, 185 * 260mm), B5 (32 open, 130 * 185mm) ......

A4 paper is larger than B5 paper. The size of A4 paper is 210mm 297mm, while the size of B5 paper is 182mm 257mm.

The aspect ratio of Group A paper sizes is 2:1 and then rounded to the nearest millimeter. A0 is defined as an area of one square meter with an aspect ratio of 2:

1 piece of paper. Next A1, A2, A3 ......For other paper sizes, it is defined as folding the paper with one less number along the long side and rounding it off to the nearest millimeter.

The size of the B paper is the geometric average of the paper in Group A with the same number and one less number. Before the popularization of printers, B-group paper was often used.

Uses of A4 and B5.

A4 has many uses: daily copying, printing, contracts, documents, tenders, leaflets, letter writing, etc.

B5 paper is small in size and is often used in schools to make books, notebooks and student rolls, **, etc.

B5 paper size size: 176mm 250mm.

B5 paper generally has two sizes, EXTRA is the international standard size, that is, 210mmx276mm, which is also commonly used now. There is also an ISO standard.

The B5 is 176mm 250mm. In the past, it was 182mmx257mm for domestic use.

History. In 1965, the national standard stipulates that the opening of books and magazines should be A, B, and C, and Group A is cut with the original whole sheet of paper of 841 mm and 1189 mm, Group B of original paper is 1000 mm and 1414 mm, and Group C of original paper is 917 mm and 1279 mm.

In 1982, GB788-87 emphasized the adoption of international standards. The new standard retains the A series that conforms to the international standard in the old standard, and at the same time adopts the international standard B series, and eliminates the B and C groups in the original standard. Its purpose is to promote foreign and international exchanges.

What we call A4, B5, etc. when we usually make copies are international standards.

B5 paper refers to B5 size paper. B5 generally has two sizes, extra, that is, the international standard size, that is, 176mmx250mm is universal.

The specification of paper refers to the fact that after the paper is made, it is trimmed and cut to a certain size. In addition, there is also the 182mmx257mm standard adopted by Chinese mainland before 1982.

What is the size of B5 paper, take a look.

B5 paper size size: 176mm 250mm. The size of a 32-page workbook used in school.

B5 paper generally has two sizes, EXTRA is the international standard size, that is, 176mmx250mm is also universal. In the past, it was 182mmx257mm for domestic use.

China adopts international standards, stipulating A0, A1, A2, B1, B2 and so onand so on to indicate the format of the paper. The standard stipulates that the ratio of the width (denoted by x) and the length (denoted by y) of the paper is x:y=1:n.

B5 paper size size: 176mm 250mm.

In the past, the size of the paper was expressed by the number of "open" (such as 8 or 16 open, etc.) in hail, but now China adopts international standards and stipulates that it is A0, A1, A2, B1, B2....and so on to indicate the format of the paper. The Yuandongqing standard stipulates that the proportional relationship between the width (denoted by x) and the length (denoted by y) of the paper is x:

y=1：n。

Notes:In 1982, GB788-87 emphasized the adoption of international standards. The new standard retains the A series that conforms to the international standard in the old standard, and at the same time adopts the international standard B series, and eliminates the B and C groups in the original standard.

Its purpose is to promote foreign and international exchanges. What we call A4, B5, etc. when we usually make copies are international standards.

B5 paper is an international standard paper size with a size of 176 mm to 250 mm. It is one of the B-series standard papers and differs compared to other paper sizes such as A-series and C-series. The size of B5 paper is comparatively smaller, slightly smaller than A4 paper.

The size of A4 paper is 210 mm and 297 mm, while the size of B5 paper is 176 mm and 250 mm. As a result, B5 paper is narrower than A4 paper in width and slightly shorter in height. B5 paper is usually used in some specific application scenarios, such as the printing and production of books, magazines, newspapers, manuals, flyers, etc.

Its smaller size makes it more convenient in terms of wrapping, carrying, and storage. It is important to note that the B5 paper ruler may vary in a particular region or in a country that uses a particular standard. This is an international standard B5 paper size, but other paper size standards may exist in some regions.

Therefore, it is best to confirm the specific use according to local standards. <>

B5 size: 176mm 250mm.

The paper size is used to standardize the length and width of the paper into a fixed proportional size. At present, the most commonly used standards in the world are the standards set by ISO, and the dimensions are numbered such as A4, B5, etc.

Extended information: The international standard paper size can be divided into three series: A, B and C. This standard is characterized by an aspect ratio of 2 (approx. ) for all paper sizes.

The geometric proportions of different sizes of paper in the same series can be directly scaled and photocopied without the problem of edge cutting of the paper pattern.

A-series. The basis for the development of the A series was to first find a sheet of paper with an aspect ratio of 2 and an area of 1 square meter (m). Therefore, the width and length of this paper are 841 mm and 1189 mm respectively (the aspect ratio is 2:

1), and it is numbered A0. If the long side of the A0 paper is cut in half, two sheets of A1 paper are obtained, both with a width of 594 mm and a length of 841 mm. In this way, if you continue to cut the A1 paper in half, you can get the paper sizes such as A2, A3, A4 and so on in order.

When setting the standard, the size is based on an integer, so if the size of the paper cut has a decimal (less than 1 mm), it will be rounded.

B series. The basis for the B series was to first find paper with a width of 1 meter and an area of 2 square meters (m). Therefore, the width and length of this paper are 1000 mm and 1414 mm respectively (the aspect ratio is 2:

1) and number it as b0. If the long side of the B0 paper is cut in half, two sheets of B1 paper are obtained, both with a width of 707 mm and a length of 1000 mm. If you continue to cut the B1 paper in half in this way, you can get the paper sizes of B2, B3, B4 and so on in order.

Compared with Series A, the paper area of Series B is twice that of Series A, for example, the paper area of Series B4 is twice that of Series A4.

C-Series. The basis for the formulation of the C series is to obtain the geometric average of the dimensions of the A series and the B series. For example, the paper size of C4 is the geometric average of the A4 and B4 dimensions, and the paper aspect ratio is still 2:

1。In this way, the size of C4 is between A4 and B4, and the A4 paper can fit into a C4 size envelope bag.
