Please do not ever use the font Rotis Semi Serif as your body text

rotis semi serif as body text

Rotis Semi Serif not a serif. It’s not a sans serif. It’s an in-betweener with hinted serifs.

Your body text does not want hinted serifs. Your body text wants either full serifs or none. But good news! Rotis does come in a serif and a sans version! In fact, the typeface comes in four variants:

  • Rotis Serif — with full serifs
  • Rotis Semi Serif — with hinted serifs
  • Rotis Semi Sans — without serifs but with stroke width variation
  • Rotis Sans — without serifs and with minimal variation on stroke width

Rotis font all faces

That’s a fun idea to develop a typeface that has not just a serif and sans serif version, but versions in between.

The typeface was created in 1988 by Otl Aicher, a German graphic designer and typographer. Wikipedia says, “He is best known for having designed pictograms for the 1972 Summer Olympics in Munich that proved influential on the use of stick figures for public signage”.

Despite Rotis Semi Serif being a poor font for body text, it’s a fine experimental font. In fact several large organizations have used it (per Wikipedia):
