Diogenes is an elegant and crisp text typeface. While the skeletons of the individual characters are distinct and strong, the serifs are fine and sharp. This is especially true for the capitals with their comparatively strong horizontal strokes. The graceful appearance of Diogenes makes it an ideal choice for books, newspapers, and magazines, both at small text sizes and display sizes. Diogenes comes in five weights from Light to Black each with Italic and Small Caps.

Design Concept

For many serif typefaces the thickness of the serifs and the weight of the thinner (primarily horizontal) strokes correspond. However, when studying ancient roman letterforms, one can see that the serifs are not simply extensions of the strokes, but independent parts of each character. Especially, when looking at the letters E, F, L and T in the image below, we can observe that the contrast between the vertical and horizontal strokes are comparatively low, however, the serifs remain thin and delicate. This was the main starting point for Diogenes. I designed the upper-case characters first, in contrast to my usual way of working. Compared with the subtle horizontal serifs the vertical serifs are slightly stronger. The proportions of the capitals are modern, meaning they are similar in width. After completing the basic forms of the capitlas, I transfered the concept to the lower-case characters. Because of the different structure the concept here is not as visible. This is no disadvantage, since lower-case characters are more important for the reading process. Finally, I would like to add a few words about the name. Diogenes is one of the classic philosophers, but was quite eccentric – just like this typeface.

Open-Type Features

Diogenes desktop fonts and web fonts contain various OpenType features, which provide advanced typographic performance and can be accessed by almost all professional layout software.

Case Sensitive Forms

When the ‘change to caps’ function is applied from within an application (not when text is typed in caps) appropriate case-sensitive forms are automatically applied. Parentheses, guillemets, dashes, hyphens and other punctuation marks are replaced with their capital forms.

All Small Caps

This feature turns capital characters into Small Capitals. It also replaces numerals and punctuation with small caps variants. Only the Diogenes Small Caps fonts contain this feature.

Alternate ampersand

Diogenes fonts contain an alternate ampersand, which is accessible via Stylistic Set 01 or Stylistic Alternates. Please note the different standard ampersand in the italic fonts.


Ligatures are designed to improve the kerning and readability of certain letter pairs. For example, when this feature is activated, typing ‘f’ and ‘i’ will automatically produce the ‘fi’ ligature. Using ligatures does not affect the spelling and hyphenation of your text in any way.

Discretionary Ligatures

This feature replaces a sequence of glyphs with a single glyph which is preferred for typographic purposes.

Contextual Alternates

This features replaces the regular ‘f’ with a narrower version to avoid collisions with following characters. Also an alternate y is available. Note: If the Ligature feature is on, the ligature has priority.

Lining Figures

Diogenes fonts contain various styles of numerals within each font. Proportional Oldstyle Figures come standard. The Proportional Lining Figures feature changes standard figures to Lining Figures in capital letter height.

Tabular Figures

Tabular figures are for use in tables where numerals need to be aligned vertically. Tabular figures are available as an OpenType feature and have a fixed width in all weights. Diogenes fonts include Oldstyle and Lining Tabular figures.

Slashed zero

To avoid confusion between a zero and the ‘o’ character, a slashed zero glyph is available.

Arbitrary Fractions

Diogenes fonts already include a number of pre-designed diagonal fractions. The fraction feature allows you to create other fractions quickly and easily.

Superscript / superiors

Replaces all figures with their superior alternates, which can be used for footnotes, formulas, etc.

Subscript / inferiors

Replaces all figures with their inferior alternates, used primarily for mathematical or chemical notation.
