Screen resolution checker FAQ
Why does this show a different number than my display settings?
Windows and macOS list the resolution you chose in display settings, which can be lower than the panel's native resolution when scaling is on. This page reports what the browser sees, multiplied by the pixel ratio.
What is devicePixelRatio?
It is the ratio between physical pixels and CSS pixels. A ratio of 2 means each CSS pixel is drawn with 4 physical pixels, which is typical for phone screens and most modern laptops.
Why is the viewport smaller than the screen size?
The viewport is the visible area inside the browser window, so it leaves out the taskbar, browser toolbar and any other windows on screen.
Does this work on my phone or tablet?
Yes. Open the page in any mobile browser and rotate the device to see both the portrait and landscape numbers.
