Frequently Asked Questions
Resolution vs viewport?
Resolution is total pixels. Viewport is browser visible area, smaller due to UI elements.
What is device pixel ratio?
DPR is ratio between physical and CSS pixels. Retina displays have DPR of 2 or higher.
Why wrong resolution?
Display scaling (125%, 150%) reduces effective resolution reported by browsers.
What is the most common screen resolution for web design in 2025?
1920x1080 (Full HD) remains the most common desktop resolution at roughly 22% market share. For mobile, 360x800 and 390x844 are dominant. Design for 320px minimum width to cover all devices.
Why does my reported screen resolution differ from my monitor's native resolution?
Display scaling (125%, 150%, 200%) reduces the reported CSS resolution. A 4K monitor (3840x2160) at 200% scaling reports as 1920x1080 to the browser. This is normal behavior controlled by your OS display settings.
Understanding Display Metrics
Screen Resolution: The total number of pixels your display can show (width x height).
Viewport: The visible area of the browser window, excluding toolbars and scrollbars.
Device Pixel Ratio (DPR): The ratio of physical pixels to CSS pixels. Higher values indicate retina/HiDPI displays.
Color Depth: The number of bits used to represent colors. 24-bit supports 16.7 million colors.
