Screen DPI/PPI & Viewing Distance Calculator

Resolution + diagonal size -> pixel density (PPI) and dot pitch.

This answers a screen pixel-density question (how sharp does this display look up close?) — for a print-sharpness question (how many pixels do I need for a clean print at this size?), see the Print Resolution / DPI Calculator instead.

Pixel density

91.79 PPI

Dot pitch

0.277 mm

Suggested viewing distance for general desktop/office use: roughly 36″–60″ (a commonly used heuristic of 1.5×–2.5× the screen's diagonal size, not a hard rule).

What is this tool?

Answers a screen pixel-density question — how sharp does this display look up close — from its resolution and diagonal size, distinct from the Print Resolution / DPI Calculator's print-sharpness question (how many pixels do I need for a clean print at this size). Also shows a commonly used desktop/office viewing-distance heuristic (roughly 1.5x-2.5x the diagonal size), cited as a rule of thumb, not a hard spec.

How to use it

  1. Enter the screen's pixel resolution (width x height).
  2. Enter the diagonal screen size in inches.
  3. Read pixel density (PPI), dot pitch, and the suggested viewing-distance range.
