What is my screen resolution?
Your screen resolution in real pixels, read instantly from your browser — plus the window size, pixel ratio and aspect ratio.

What the numbers mean
- Screen resolution: the number of real pixels across and down your display, e.g. 1920 × 1080 (Full HD) or 2560 × 1440 (QHD).
- Browser window: the space websites get, in CSS pixels. It is smaller than the screen because of toolbars and the taskbar.
- Pixel ratio (DPR): how many real pixels make one CSS pixel. Phones use 2–3 so text stays sharp; Windows scaling of 125% or 150% shows up as 1.25 or 1.5.
- Aspect ratio: the screen's shape — 16:9 for most monitors and TVs, 16:10 for many laptops, 21:9 for ultrawides, about 19.5:9 for modern phones.
Why it might differ from the box
- Display scaling: websites see your resolution through the system scaling; the number shown here already corrects for it.
- Browser zoom: if the page is zoomed, press Ctrl + 0 (⌘ + 0 on Mac) and the numbers become exact.
- Wrong resolution set: if this shows less than your monitor's native resolution, the picture is blurry. Fix it in Windows Settings → System → Display → Display resolution ("Recommended").

How do I find my screen size in inches?
Use the PPI calculator with your resolution and the diagonal from the specs, or measure it with the screen ruler.
