trying to change the size of file chooser windows

Help

I’m trying to change the window and font size for file chooser windows as they are way to small for my 4k screen. I’m using KDE plasma 6.7.3 as my desktop environment

On my system, running Arch Linux with systemd, I achieved it by doing this:

mkdir -p ~/.config/systemd/user/plasma-xdg-desktop-portal-kde.service.d

Then:

nano ~/.config/systemd/user/plasma-xdg-desktop-portal-kde.service.d/override.conf

I added the following and saved the file. You can change 1.5 to whatever scale factor you find most convenient:

[Service]
Environment=QT_SCALE_FACTOR=1.5

Then I reloaded the systemd configuration and restarted the service:

systemctl --user daemon-reload
systemctl --user restart plasma-xdg-desktop-portal-kde.service

This method is specific to systemd-based setups. If you’re using a different distro or service manager, the steps may be different.

Could you share your system information with me? I can then figure out how to do the same thing on your system.

What you can do for the windows size is to set up a window rule but I’m still trying to figure out how to do change the font size
