Screen Resolution FAQ
What is my screen resolution?
Your screen resolution is the number of pixels displayed horizontally and vertically on your monitor. Common resolutions include 1920×1080 (Full HD), 2560×1440 (2K), and 3840×2160 (4K). Higher resolutions provide sharper images and more screen space.
What is the difference between screen resolution and viewport?
Screen resolution refers to your monitor's total pixel dimensions. Viewport size is the actual visible area in your browser, which may be smaller due to toolbars, window size, or browser chrome. Viewport is what websites actually see.
What is Device Pixel Ratio (DPR)?
Device Pixel Ratio indicates how many physical pixels are used to display one CSS pixel. A DPR of 2 (Retina/HiDPI) means each logical pixel uses 4 physical pixels (2×2), resulting in sharper images. Most modern phones and Macs have DPR of 2 or 3.
Why do I need to know my screen resolution?
Knowing your screen resolution helps when designing websites, choosing wallpapers, setting up screen recording, troubleshooting display issues, or optimizing images for your specific display. It's also useful when purchasing monitors or testing responsive designs.
