Frequently Asked Questions
Screen resolution refers to the number of pixels displayed on screen, expressed as width × height (e.g., 1920 × 1080). Higher resolution means more pixels and sharper images.
Screen size is the total physical screen dimensions. Available size is the usable area after subtracting taskbars, docks, or other OS-reserved areas.
Device Pixel Ratio (DPR) is the ratio of physical pixels to CSS pixels. A DPR of 2 means a 2×2 grid of physical pixels for every CSS pixel — common on HiDPI/Retina displays.
Viewport size is the visible area of the browser window, excluding browser chrome like toolbars and scrollbars. It changes when you resize the window.
