Haettenschweiler is a realist sans-serif typeface based on an uppercase metal-cast type called Schmalfette Grotesk (German for bold condensed sans-serif). The face is named for Walter Haettenschweiler, who with Armin Haab, published the book Lettera which uses Schmalfette Grotesk.
Haettenschweiler is often compared with Helvetica Inserat and Impact. Haettenschweiler has narrower characters than Impact. The uppercase R has a curved tail similar to that in the Helvetica family. Counters are minimal, contributing to a loss of legibility in smaller point sizes and in distance reading. The face is installed with Microsoft Office products and is widely available as shareware. It is used in the Nottingham Forest logo, with a modified R and a lowercase E at upper-case height.
A 2010 Princeton University study involving presenting students with text in a font slightly more difficult to read found that they consistently retained more information from material displayed in so-called disfluent or ugly fonts (Monotype Corsiva, Haettenschweiler, Comic Sans Italicized were used) than in a simple, more readable font such as Arial.
