Screen Resolution Checker
Check your current screen dimensions and available screen area as reported by the browser in CSS pixels.

These readings stay in your browser. This tool does not save them, create an identifier or transmit a report.
Screen size versus physical resolution
The screen width and height describe the browser-reported display in CSS pixels. Available width and height describe the area available for windows after system interface areas, where the browser exposes that difference.
These numbers are not a reliable measurement of the panel’s native physical resolution. Display scaling, browser settings and privacy protections can affect them. This tool reports only the current screen, not an inventory of monitors. Move the window to another display or rotate the device to see updates. Pause live updates to keep a snapshot for copying.
