At first, the idea of using small-caps for acronyms etc. is very appealing, but typographic success depends on an appropriate font: if the small-caps have the same x-height, then plurals and mixed case forms look quite poor (OpenMP, DoE, GeV, PDEs) etc. leading some to abandon the approach altogether (see this thread about typesetting units for example.)
What fonts provide suitable mid caps (quarter caps?) to support consistent and thorough use of small-caps for acronyms etc.?
I know Actium, but at the time of writing, however, this is the only font with the "mid caps" tag on MyFonts. Many other fonts are suitable: FF Atma provides both mid and quarter caps for example, and other fonts like Vesper Pro (as discussed in this thread) have larger SC with the x-height caps as petite caps. What other fonts provide this or similar features? (If you know of too many alternatives to list, I am mostly interested in text-faces for extended scientific, so fonts that would work well with math fonts such as Zapf's AMS Euler font would be appreciated.) I know of the following:
- Actium: Actium is discussed in this thread and supports a wonderful "Smart Capo" feature of contextual alternatives that automatically replaces acronyms etc. with appropriate midsize caps (try it out in the MyFonts sample - though this fails to capitalize acronyms at the start of the sentence. Probably just a sample limitation.) Are there any other fonts with contextual alternatives?
- FF Atma Serif: Provides mid caps and quarter caps. (Not exactly sure if this is implemented as separate weights or with the OTF Petite-Caps feature.)
- Vesper Pro: Provides larger SC and x-height petite caps.
What other fonts would work well for a complete treatment of acronyms, units, etc. with small or mid caps?
p.s. As I am new to this site, I did not yet start a wiki page to collect this list, but will if the thread manages to collect a good selection of fonts. What would be the best index to include this under? Perhaps a FAQ?
