Convert pixels to inches (and inches to pixels) at any DPI, for print sizing, design specs and screen dimensions.
| Input | Result |
|---|---|
| 1920 px at 96 DPI | 20.00 inches |
| 1920 px at 300 DPI | 6.40 inches |
| 300 px at 300 DPI | 1.00 inch |
| 8.5 in at 300 DPI (reverse) | 2550 px |
| Print size | Pixels needed (300 DPI) |
|---|---|
| 4×6 in | 1200 × 1800 px |
| 5×7 in | 1500 × 2100 px |
| 8×10 in | 2400 × 3000 px |
| Letter (8.5×11 in) | 2550 × 3300 px |
| 11×14 in | 3300 × 4200 px |
| Poster (18×24 in) | 5400 × 7200 px |
A photo that looks sharp on a 96-DPI screen (e.g. 1920 px wide ≈ 20 in) only prints sharp at 300 DPI up to 6.4 in wide, DPI is the bridge between screen and paper.
Because DPI (dots per inch) is the density setting. 1920 px is 20 inches on a 96-DPI screen but only 6.4 inches printed at 300 DPI, pixels are count, DPI is density, inches are the result.
300 DPI is the standard for crisp photo prints; 150 DPI is acceptable for posters viewed from a distance; large banners can go as low as 100 DPI.
Multiply by DPI: an 8.5-inch-wide letter page at 300 DPI needs 2550 px. The reverse formula is on this page, enter inches×DPI as pixels.
Browsers standardize CSS at 96 DPI regardless of hardware, so 96 is the right value for web design questions; device pixel ratios complicate retina screens.
