Do not edit. gtk-theme-name = "Adwaita" style "user-font" { font_name="FreeSans 12" } widget_class "*" style "user-font" Regarding qt5 I have no idea, and as already pointed out, I don't care, since just the font size always was and still is annoying here, but the font type is ok.

If you wish to make your GTK+ styles match your Qt styles please read Uniform look for Qt and GTK applications. Configuration of Qt apps under environments other than KDE Unlike Qt4, Qt5 doesn't ship a qtconfig utility to configure fonts, icons or styles. Instead, it will try to use the settings from the running DE. In KDE or GNOME this works well, but in other less popular DEs or WM it can lead to missing icons in Qt5 applications. One way to solve this is to fake the running desktop environment by setting XDG_CURRENT_DESKTOP=KDE or GNOME, and then using the corresponding configuration application to set the desired icon set. Another solution is provided by the qt5ct package, which provides a DE independent Qt5 QPA and a configuration utility. After installing the package, run qt5ct to set an icon theme, and set the environment variable QT_QPA_PLATFORMTHEME="qt5ct" so that the settings are picked up by Qt applications." - https://wiki.archlinux.org/index.php/qt#GTK.2B_and_Qt
