To get the most suitable design, you need to know the size of the paper sizes as well as convert them to Pixel. The use of different sizes will meet different image usage needs.
So now let's find out the size of paper in Photoshop.
Paper size in Photoshop
A4 size is the most commonly used paper size today, in any field. To have a good design on A4 size paper, you not only need to care about the length of the length, the width, but also the consideration of choosing Pixel.
The standard size for A4 size paper is: 210 x 297 mm = 21 x 29.7 cm = 8.27 x 11.69 inches .
The higher the PPI (Pixel per Inch), the more detailed and quality the image on the paper, depending on the needs we choose. The following is a Pixel spreadsheet in A4 size:

For sizes of other sizes, the ISO standard states: the ratio of the height to the width of the paper size is √2 (square root of 2), each subsequent paper size will be equal to half of the previous paper size. That (length of width after suffering = width of previous format).
Summing up the sizes of current paper sizes:
Paper size

(unit: mm)
Vertical x Horizontal
(unit: inch)
4A0
1682 x 2378 mm
66.2 x 93.6 in
2A0
1189 x 1682 mm
46.8 x 66.2 in
A0
841 x 1189 mm
33.1 x 46.8 in
A1
594 x 841 mm
23.4 x 33.1 in
A2
420 x 594 mm
16.5 x 23.4 in
A3

A5
148 x 210 mm
5.8 x 8.3 in
A6
105 x 148 mm
4.1 x 5.8 in
A7
74 x 105 mm
2.9 x 4.1 in
A8
52 x 74 mm
2.0 x 2.9 in
A9
37 x 52 mm
1.5 x 2.0 in
A10
26 x 37 mm
1.0 x 1.5 in
To make it easier to imagine, you based on the following figure, according to the rule, A0 is the largest format, dividing A0 into A1, dividing A1 into A2 .
