Tools
Start with visual size comparison, then check TV viewing distance, PPI, scaling, readability, viewport size, and the browser-side details your current device exposes.
Core tool
Compare two phones, monitors, TVs, tablets, or custom screen sizes side by side with real width, height, area, and visual scale.
TV calculator
Estimate the right TV size for your sofa distance, then check complete 32-115 inch distance and dimensions charts.
PPI check
Enter screen size and resolution to calculate PPI, pixel density, pixel pitch, diagonal pixels, and a quick sharpness read for phones or monitors.
Resolution & scaling
Check how monitor size, resolution, PPI, and Windows scaling work together before you buy or reconfigure a display.
Screen check
Check your screen resolution, viewport size, browser window size, available screen area, and device pixel ratio in one place.
Shape comparison
Compare familiar and custom screen shapes without pretending that diagonal, height, and width mean the same thing. Switch the matching rule to see the difference that matters for your desk or content.
Desk planning
Arrange one to four monitors, rotate screens and check desk width with adjustable borders, gaps and side margins. Share the exact layout.
