Method 3: Through the Terminal

The size of the text can also be changed directly from the Terminal application in your Debian system. To do so, use the following command syntax in Terminal:

$ gsettings set org.gnome.desktop.interface text-scaling-factor <scaling_factor-value>

For instance to scale the text size 1.5 times, run the following command in Terminal:

$ gsettings set org.gnome.desktop.interface text-scaling-factor 1.5

gsettings app - change text size

To reset the text size back to default settings, you can run the following command in Terminal:

$ gsettings reset org.gnome.desktop.interface text-scaling-factor

Reset text size

That’s all there is to it! I hope it will be helpful if you ever need to change the size of the text in your Debian OS.
