    I'm using Opera 38.0.2220.29 for Windows 10 64-bit.
    When I open the DevTools -> device mode I get very small dimensions for the mobile screen.
    In Chrome the dimension look pretty similar to the result on my actual phone, on opera the screen is way too small:

    Does anybody know why the screens are so small?

  • That's strange, I tried and in my case the size is effectively 411 x 731 pixels. Have you checked you don't have any other extensions that may be interfering? The easiest way is to open a new private window (unless you allowed the extension in those cases).

  • I disabled all extensions, no luck. Then I even uninstalled Opera and reinstalled it, but still the same problem.
    The rulers are correct. But somehow there might be a problem calculating the actual dimension.

    I made a little test where I displayed the document.width using JavaScript. Thats the result:

    As far as I can see there are no zooms or anything else set.
