Formula

inches = pixels / DPI

cm = inches x 2.54

// 1280x800 at 300 DPI: 4.27" x 2.67" (10.84 x 6.77 cm)

// at 150 DPI: 8.5" x 5.3" - use for posters

Which DPI should I pick?

300 DPI - photo prints, brochures, reading distance < 60cm. Sharp at arm's length. 1280x800 is 4.27x2.67in.
150 DPI - posters, banners, viewing beyond 1m. Larger but slightly softer. 8.5x5.3in.
72 DPI - screen proof only; prints 17.8x11.1in but visibly pixelated.
600 DPI - fine art or small text overlays; 2.13x1.33in, 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. 2560x1600) and keep DPI at 300. Upscaling adds no real detail - viewing distance hides it for posters but not for hand-held prints.
