Frequently Asked Questions
What is DPR?
Device Pixel Ratio (DPR) is the ratio between physical and CSS pixels. Retina displays typically have a DPR of 2 or 3.
Screen vs viewport size?
Screen resolution is your monitor's full size. Viewport is the browser's visible area, which is smaller due to toolbars and OS chrome.
Why is actual resolution different?
Actual resolution = screen resolution × DPR. A 1920×1080 screen with DPR 2 renders 3840×2160 physical pixels.
