Foire Aux Questions (FAQ)
Why does my screen size differ from my window size?
Screen size represents your monitor's full resolution, while window size is the browser viewport's current dimensions. The window is typically smaller because it excludes the browser chrome (toolbars, address bar) and may not be maximized.
What is device pixel ratio?
Device pixel ratio (DPR) is the ratio between physical pixels and CSS pixels. A DPR of 2 means each CSS pixel is rendered using 4 physical pixels (2x2). Retina and high-DPI displays typically have a DPR of 2 or higher.
Is the information collected by this tool accurate?
The tool uses standard browser JavaScript APIs, so the information is as accurate as what your browser reports. Some browsers may limit or modify certain values for privacy reasons, such as reducing the reported screen resolution.
