Why A4 Pixel Size Depends on DPI (Dots Per Inch)
Unlike physical sheets of paper that stay 210 × 297 mm forever, a digital pixel has no fixed physical size until it is assigned a DPI (Dots Per Inch) or PPI (Pixels Per Inch) value.
If you create a canvas at 595 × 842 pixels and send it to a commercial laser printer, the print will appear grainy and pixelated because the printer only has 72 dots of color per inch to reproduce.
For professional, razor-sharp output where text and lines look like offset printing, always configure your canvas at 2480 × 3508 pixels (300 DPI).
