    // a4 page size = 210mm*297mm
    QGraphicsScene* scene = new QGraphicsScene(0, 0, ?, ?);
    

    How can I do it in millimeters?

      @_compiler Don't know why you want to do it, but I think you will need to know the resolution of used display: how many pixels per millimeter? If you know the resolution then you can do: 96*100 (in this example 96 is the resolution and you want to have 100mm).
