This tool reads your browser's window and screen APIs to report your actual display metrics. The viewport is the visible browser area, while the screen resolution reflects your physical display.
The device pixel ratio (DPR) tells you how many physical pixels correspond to one CSS pixel. A DPR of 2 means you have a Retina or HiDPI display — your screen packs twice the pixels in the same space.
All detection happens entirely in your browser. No data is sent to any server.
