      @diredko you can take a look at the Scalability section of the documentation The calculating scaling ratio section has an example that used to help me a lot when I first was confronted with this issue.

      @johngod Thank you so much, you're right Screen.pixelDensity would be the complete solution if it was in qml, sifting trough the qt source i was able that it was derived from: double pixelpermm = QGuiApplication::primaryScreen()->physicalDotsPerInch() / 25.4 //physicalDotsPerInchX() & physicalDotsPerInchY() also exist and it seems to be correct on both my iPhone & iPad quite wel (better than all other ways I found so far) @Lorenz thanks, but for the time being I want to stick to Qt as it is a paid sdk as soon as you go commercial
