If we want to design a magazine image, how many pixels and resolutions are required for the A4 size? In general, the 300dpi used for copper paper is enough.

The physical size of A4 is 21 cm × 29. 7 cm. The specific conversion to

Calculation methodThe general resolution is XX pixels per inch, where one inch is 25.4 mm.So the number of pixels in a millimeter is xx/25.4. Now the job is to ask for the value of XX, the value of XX to find out later,The pixel width of the A4 paper is obtained directly with xx/25.4 * 210.The size of A4 paper is 210mmx297mm.When the resolution is 72 pixels per inch, the pixel of the
