What is the size of the frame of a4?

The drawing size of A4 is 210*297.

The picture frame has a standard format, which is divided into two types. One type requires binding. It is generally installed vertically in A4 format, leaving 25mm on the left and 5mm on the other sides. It is now used more often. The other type does not require binding, leaving 5mm on all four sides.

The aspect ratio of paper size in group A is √2:1, and then rounded to the nearest millimeter value. A0 is defined as paper with an area of ​​one square meter and an aspect ratio of √2:1. The following paper sizes such as A1, A2, A3, etc. are all defined as folding the paper with one size less number in half along the long edge, and then rounding off to the nearest millimeter. The size of paper in Group B is the geometric mean of the paper in Group A with the same number and one size less. Before printers became popular, Group B paper was mostly used. Group C paper sizes are mainly used for envelopes.

Extended information:

The basis for formulating the A series is to first find a piece of paper with an aspect ratio of √2 and an area of ​​1 square meter (m²) . 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, you will get two A1 papers, whose width and length are both 594 mm and 841 mm.

Continue to cut the A1 paper in half in this way, and you can get the paper sizes of A2, A3, A4, etc. in sequence. When setting standards, sizes are always in whole numbers, so any decimal (less than 1 mm) cut paper size will be rounded off.
