Formula
inches = pixels / DPI
cm = inches x 2.54
// 3840x2160 at 300 DPI: 12.80" x 7.20" (32.51 x 18.29 cm)
// at 150 DPI: 25.6" x 14.4" - use for posters
Which DPI should I pick?
- 300 DPI - photo prints, brochures, reading distance < 60cm. Sharp at arm's length. 3840x2160 is 12.80x7.20in.
- 150 DPI - posters, banners, viewing beyond 1m. Larger but slightly softer. 25.6x14.4in.
- 72 DPI - screen proof only; prints 53.3x30.0in but visibly pixelated.
- 600 DPI - fine art or small text overlays; 6.40x3.60in, doubles file size.
Scaling tip - when pixels are short
Need a larger print than the table allows? Do not upscale blindly. Instead halve the DPI (300 -> 150) to double inches, or pick a larger master (e.g. 7680x4320) and keep DPI at 300. Upscaling adds no real detail - viewing distance hides it for posters but not for hand-held prints.
