COMMON QUESTIONS

Screen resolution is your monitor's total pixel dimensions (e.g., 1920×1080). Viewport size is the current browser window size, which may be smaller if the window isn't maximized.
Device Pixel Ratio (DPR) indicates pixel density. A DPR of 2 means each CSS pixel contains 2×2 physical pixels. Higher DPR provides sharper images on high-DPI displays like Retina screens.
Available area excludes space used by the operating system (taskbar, dock, menu bars). This is the actual usable screen space for applications.
Aspect ratio is the proportional relationship between width and height. Common ratios include 16:9 (widescreen), 16:10, 21:9 (ultrawide), and 4:3 (traditional).
Physical screen size cannot be detected via browser APIs as it requires hardware specifications. You can find this information in your device's specifications or settings.
Yes! The tool works on all devices including phones, tablets, and desktops. It will show your device's screen resolution and automatically update when you rotate the device.
Color depth (bit depth) determines how many colors can be displayed. 24-bit (8 bits per channel) displays 16.7 million colors. Higher bit depths provide smoother gradients and better color accuracy.
The DPI estimate is calculated based on device pixel ratio and assumes a standard 96 DPI baseline. Actual DPI depends on physical screen size, which browsers cannot detect. For accurate DPI, check your device specifications.
