Screen resolution and device details
This tool instantly shows your screen resolution, viewport (the browser’s visible area), pixel ratio (device pixel ratio) and color depth. Everything is read in your browser.
Resolution vs viewport
Screen resolution is the monitor’s physical pixels; the viewport is the visible CSS area of the window, which changes as you resize. On high-density (Retina) screens, the pixel ratio tells how many physical pixels there are per CSS pixel.
Common resolutions
- 1920×1080 (Full HD): the most common on desktop.
- 1366×768: basic laptops.
- 2560×1440 (QHD) and 3840×2160 (4K).
- Phones: 360×800, 390×844, 412×915 (in CSS pixels).
Frequently asked questions
Why doesn’t my resolution match the maker’s spec? The browser reports CSS pixels; with a pixel ratio >1, multiply for the physical ones.
Does it update on resize? Yes, the viewport is recalculated when you resize the window.
