Screen Resolution Detector
Real-time display of screen, window, and document dimensions with device pixel ratio and color information.
Screen Resolution
Screen resolution represents your monitor's physical pixel dimensions. Available dimensions exclude system UI elements like taskbars.
Browser Window Size
Inner dimensions represent the viewport (content area). Outer dimensions include browser chrome (toolbars, scrollbars).
Document Page Dimensions
Scroll dimensions include the entire document including overflow. Client dimensions represent the visible viewport area.
Device Pixel Ratio
Device Pixel Ratio indicates how many physical pixels correspond to one CSS pixel. Higher values (2x, 3x) are common on Retina/HiDPI displays for sharper rendering.
Color Information
Color depth indicates bits per pixel. Color gamut shows the range of colors your display can reproduce.
Screen Orientation
Screen orientation changes when you rotate your device or resize the browser window across aspect ratio thresholds.
