Well, yes and no. You can't say a widget uses "standard pixel size plus X". You can set a standard font on QApplication with the size you want: QFont font; font.setPixelSize(23); QApplication::setFont(font); That part is easy enough. But in places where you have custom drawing with other sizes, you need to do the same kind of thing: QFont f; // This is the standard font f.setPixelSize(f.pixelSize() + 3); setFont(f); // Or use f with the painter You can listen for font changes with the changeEvent() in widgets. If you use the QWidget::setFont(), this is necessary. If you just use it in the painter, it's not necessary. In all text based widgets with rich text, you can use <font size="+3"> and then it just works. With style sheets, you can't do this. In QML you can do sort of the same things. But I assumed this was a QWidget based question.
