On the dialog shown in the following screenshot you can change the font that is used to draw your diagrams.

You need to choose a font that supports Unicode. Check the test string in the font dialog and make sure you see an arrow (←), the symbol for an empty set (∅), and the compound comparison operator symbols (≠, ≤, ≥) between the brackets.

The following fonts should be fine (as far as available):

  • Arial Unicode
  • Dialog
  • Lucida Bright
  • Lucida Sans
  • Lucida Sans Unicode
  • Monospaced
  • OpenSymbol
  • SansSerif
  • Serif

If you just want to size up or down the current font then you might use the toolbar speedbuttons Toolbar font resizing speedbuttons or key combinations <Ctrl><Numpad+> / <Ctrl><Numpad-> instead. Since version 3.28-01 you may alternatively use the mouse wheel with <Ctrl> key pressed (zoom function).

Note: The font chosen here is only used for drawing the diagrams. It is not subject to the GUI Scaling preference. Both are completely independent.

Between versions 3.28-07 and 3.28-08 the way the diagrams adapt to the chosen font was modified: Before, the element padding (the margin around the text) had been constant, i.e. independent of the font size. This way, with a larger font, the text used to occupy a relatively greater share of the enclosing element than with a small font:

Now (i.e. with versions after 3.28-07) the padding is by default relative to the font size such that the proportions of the diagram will no longer degrade on changing the font size. For backward compatibility, however, a checkbox was added to the font dialog allowing to force the traditional fix padding again:

At the same occasion the line spacing was somewhat reduced, which particularly affects multi-line instruction elements.
