Screen and viewport, live

Screen size, available area, devicePixelRatio, layout and visual viewports, orientation, and preference media features — read in this tab and kept live, with the fingerprinting implications named.

Values appear after hydration — resize or zoom the window and they update live.

Screen size, devicePixelRatio, color depth, and color-scheme together form a well-known fingerprint vector — every site reads them silently; this page just shows them to you.

- devicePixelRatio fuses panel density and browser zoom — a “2” can be a retina panel at 100% or a 1080p panel at 200%. Neither half is separable from the web.
- The available-area difference exposes your dock/taskbar side; the visual-viewport scale exposes an active pinch zoom. Small facts, identifying in combination — shown here precisely because they are readable without asking.
- Nothing is uploaded; refresh the page, resize, or rotate to see the values track.

the first read happens after hydration — the prerendered HTML contains no screen values
