Your display server (x11 or wayland) will be relevant as well as your output configuration (how many monitors and what kind)
For X11
xrandr -q
xdpyinfo | grep reso
xrdb -q | grep -i dpi
and generally
printenv
for all the scale features of the toolkits.

Thanks a lot. I work with a laptop and external monitor and set the scaling on my laptop to 120%. So I set it to 100% and my LibreOffice back to normal. Not certain what caused this since I didn't have this problem before.

This will likely be around https://wiki.archlinux.org/title/HiDPI#GDK_3_(GTK_3) if you've to "unscale" the font dpi?
You'd have to provide more details on the environment (display server, variables and where you "set the scaling") for a more informed comment.
