Hi Markus. There is no option to set the standard font size in Mendix Studio Pro. Also not in Mx10.1.0. There options to set the zoom-percentage (Ctrl+mousewheel) and the focus options (F11 and/or shift-F11) but that does not change the font-size of the menu-bars and navigation windows. The only font-file you can find in your studio’s /modeler directory is “glyphicons-halflings-regular.ttf”, but you can not change that to my knowledge.

Hi Markus Rödle,

When using a Text widget, the render mode property can be set. 

When you want to change the font sizes of the defined render modes, you alter the values in the custom-variables.scss to be found in your App <x> → Styling → web folder (in the App Explorer on the left)  in the Advanced section.

If you have multiple applications that you need to change you should consider the creation of a Design System. Go to the Learning Path on this topic for more details.

I feared that there will be no possibility to change the font size of the IDE itself.
