Frequently Asked Questions
What is the difference between screen resolution and viewport size? +
Screen resolution is the total pixel count of your monitor. Viewport size is the visible area of the browser window, which is smaller due to toolbars, scrollbars, and window chrome.
What is device pixel ratio? +
Device pixel ratio (DPR) is the ratio of physical pixels to CSS pixels. A DPR of 2 means each CSS pixel maps to a 2x2 grid of physical pixels, common on Retina and high-DPI displays.
Why does my resolution look different from my monitor's spec? +
Display scaling in your OS settings can make the reported CSS resolution differ from native hardware pixels. The device pixel ratio accounts for this difference.
