Frequently Asked Questions
What is screen resolution?
Screen resolution is the number of pixels displayed on your screen, expressed as width × height (e.g., 1920×1080). Higher resolutions show more detail and allow more content to fit on screen.
What's the difference between screen size and viewport size?
Screen size is your monitor's total resolution. Viewport size is the visible area of your browser window, which is smaller due to browser toolbars, taskbar, and window borders.
What is device pixel ratio (DPR)?
Device pixel ratio is the ratio between physical pixels and CSS pixels. A DPR of 2 (Retina display) means each CSS pixel is displayed using 4 physical pixels, resulting in sharper images.
Why does my viewport size change when I resize the browser?
The viewport is the visible area of your browser window. When you resize the window, the viewport changes accordingly. This is important for responsive web design.
