Screen Resolution
This is the screen size your device reports to the browser, often shown as width × height.
Viewport Size
This is the visible webpage area. It changes when the browser window is resized.
Pixel Ratio
High-DPI displays may use more physical pixels to draw one CSS pixel, making screens look sharper.
Note: Browser-reported screen size may differ from the monitor’s marketing resolution because of scaling, browser zoom, operating system display settings, mobile browser behavior, or privacy protections.
