[Tex/LaTex] Which font should be used for diagrams/graphs/flow charts


I'm using the standard serif fonts in KOMA script for typesetting my thesis, 11pt for normal text.
What font and font size would be recommended for use in graphs, diagrams and flow charts?

The same font as the normal text or a sans serif font for better "contrast"?

What about font size in graphics?

I found recommendations of Springer publishing for preparing graphics for their books, which are quite interesting and helpful:


They say:

Figure Lettering

  • To add lettering, it is best to use Helvetica or Arial (sans serif fonts).
  • Keep lettering consistently sized throughout your final-sized artwork, usually about 2–3 mm (8–12 pt).
  • Variance of type size within an illustration should be minimal, e.g., do not use 8-pt type on an axis and 20-pt type for the axis label.
  • Avoid effects such as shading, outline letters, etc.
  • Do not include titles or captions within your illustrations.

For the moment I've decided to use the Sans Serif fonts with the \sffamily command for my graphics.
