Is 300 DPI Universally Required for A4?

While 300 DPI (2,481 × 3,507 px) is the standard benchmark for close-up handheld viewing, it is not universally mandatory for every printing project. The appropriate resolution depends on four key factors:

1. Viewing DistancePrints held at arm's length (12 in) benefit from 300 DPI, while wall prints viewed from 3–5 feet away look crisp at 150–200 DPI.
2. Physical Print SizeSmall frames require high pixel density, whereas large posters and signs require far lower DPI to appear sharp to the human eye.
3. Print Method & SubstrateGlossy photo paper and offset presses capture micro-detail, while textured canvas, matte watercolor paper, and textiles naturally mask lower DPI.
4. Printer & Provider SpecsCommercial book publishers mandate strict 300 DPI files in preflight, whereas sign and banner shops typically request 100–150 DPI.
