Frequently Asked Questions
What is screen resolution?
Screen resolution is the number of pixels displayed on your screen. It's measured as width × height (e.g., 1920 × 1080).
What is the difference between screen and viewport?
Screen resolution is your physical display size. Viewport is the visible area of the browser window, which may be smaller if the window is resized or zoomed.
What is device pixel ratio?
Device pixel ratio is the ratio between physical pixels and CSS pixels. High-DPI displays (like Retina) have ratios greater than 1, meaning more physical pixels per CSS pixel.
