PPI Calculator
Work out a screen's pixel density from its resolution and diagonal size: PPI, dot pitch, physical dimensions, aspect ratio, and the distance at which it becomes "Retina". Pure math, offline in your browser session.
| PPI | 108.79 |
|---|---|
| Dot pitch | 0.23 mm |
| Aspect ratio | 16:9 |
| Screen size | 23.5 × 13.2 in (59.8 × 33.6 cm) |
| Resolution | 2560 × 1440 px (3.69 MP) |
| Retina distance | 80.3 cm (31.6 in) |
Retina distance is the closest viewing distance at which a 20/20 eye can no longer resolve individual pixels (one pixel spans one arcminute). Closer than this and pixels become visible.
