🖥️Screen Resolution Checker

Your display details, detected instantly — no input needed.

Device Pixel Ratio Physical px per CSS px
Color Depth Bits per pixel
Orientation Portrait or landscape
Screen Aspect Ratio Width : height ratio

Note: Values are in CSS pixels as reported by your browser. On high-DPI displays, OS scaling means the screen resolution shown here may differ from your monitor's native panel resolution — that's expected. The "Actual Pixels" row shows the physical pixel count your browser uses (viewport × DPR).

Free Screen Resolution Checker — What Is My Screen Resolution?

Wondering what your screen resolution actually is? Our free screen resolution checker detects it instantly — no input needed. The moment the page loads, it shows your display's resolution, your browser's viewport size, the device pixel ratio, color depth, orientation, and your screen's aspect ratio, all in one clear readout.

It also explains the differences that usually cause confusion: your screen resolution isn't always the same as your browser's viewport, and high-density displays report a pixel ratio that affects how sharp everything looks. Resize your window or rotate your device and the numbers update live, so you can see exactly how your viewport changes. It's handy for web designers checking breakpoints, gamers and shoppers confirming a display, or anyone troubleshooting how a site or video looks on their screen. One click copies everything to share or note down.

Just open the page to see your screen details instantly. No sign-up, no downloads, no limits — just the facts about your display.
