About PPI Calculator

PPI Calculator is an informational tool for understanding the relationship between display resolution, physical dimensions, and pixel density. It is designed for designers, developers, students, reviewers, and display buyers who need reproducible measurements from a small set of specifications.

Scope

The calculations use the resolution and diagonal size you provide. The screen illustration is proportional only; it is not a calibrated physical-size display. Viewing-distance results are a practical reference model, not a statement about any individual’s vision.
