About ScreenPPI

ScreenPPI is a free, privacy-first display calculator built for developers, designers, gamers, and tech enthusiasts. Every calculation—pixel density (PPI/DPI), physical dimensions, dot pitch, retinal viewing distance, and dual-screen comparisons—runs entirely in your browser. No data leaves your device.

We created ScreenPPI because comparing display specifications across devices shouldn't require spreadsheets or guesswork. Our device presets use official manufacturer PPI values rather than computing them from rounded marketing diagonals, which eliminates the ±2 PPI drift common in other calculators.

ScreenPPI is maintained independently and supported by non-intrusive advertising. For questions, suggestions, or device preset requests, visit our Contact page or email [email protected].
