The Screen Resolution Detector is a free online tool that instantly shows your device’s screen resolution, aspect ratio, color depth, and pixel density.

Open the Screen Resolution Detector tool on your browser.
It automatically detects and displays:
Your screen resolution (width × height)
Aspect ratio (e.g., 16:9)
Color depth (in bits)
Device pixel ratio
Resize or rotate your screen — the tool updates instantly.
Optionally, copy the data to share or record for your setup.
Screen resolution represents the number of pixels (width × height) your display uses to show images. For example, 1920×1080 means Full HD resolution.
The aspect ratio is the proportional relationship between width and height — like 16:9 for widescreen displays.
Pixel ratio shows how many physical pixels correspond to one CSS pixel. High pixel ratios indicate sharper displays (like Retina screens).
It shows your device’s screen resolution by default, not the browser window size.
No. The tool runs directly in your web browser and works on any device — desktop, laptop, tablet, or phone.
