At the moment, I do not have options for this. The client tries to pull from your system UI scaling value. I will introduce some better font scaling options in the client.
For now, if you add this text to a new qss file in install_dir/static/qss/, and then set that as your style in options->style, you can force different font sizes:
/* You can set the pt value to whatever you like */
QWidget
{
font-size: 14pt
}
