For work purposes I am running Fedora desktop in Virtualbox but compared to Windows 10 guest fonts looked quite smaller in Fedora. Settings in Gnome by default have only 100% and 200% options which are not matching 125% used by Windows. So in order to set it up properly you need to run this command in the terminal:
gsettings set org.gnome.desktop.interface text-scaling-factor 1.25
Change will be applied immediately.
