What do these numbers mean?
- Screen resolution is the size of your display in CSS pixels as reported by the browser.
- Pixel ratio shows how many physical pixels make one CSS pixel; 2 or more means a high-density (Retina) screen.
- Physical pixels is resolution multiplied by pixel ratio — roughly your display’s true pixel count.
- Browser window is the visible page area and changes as you resize the window.
