The Screen Resolution Detector is a simple utility for web designers and front-end developers. It provides key details about your display and browser window, which are essential for testing responsive websites and understanding how a user sees your site.
The tool instantly reports your physical screen's width and height, the current size of your browser's content area (the viewport), your monitor's color depth, and the device pixel ratio (which indicates if you have a HiDPI/Retina display). You can resize your browser window and click 'Refresh' to see the viewport values update in real time.

Frequently Asked Questions
What is the difference between Screen Resolution and Viewport Size?
Screen Resolution is the total number of pixels on your physical monitor (e.g., 1920x1080). Viewport Size is the dimensions of the visible content area inside your browser window. The viewport is usually smaller than the screen resolution, especially if the browser is not in full-screen mode.
What is the Device Pixel Ratio (DPR)?
DPR is the ratio between physical pixels on the screen and logical pixels (CSS pixels). A DPR of 2 means that one CSS pixel corresponds to a 2x2 grid of physical pixels. This is common on 'Retina' displays and results in sharper text and images.
