FF Eureka Sans supports 113 different languages such as Spanish, English, Portuguese, German and French in Latin scripts. (Please note that not all languages are available for all formats.)
FF Eureka Sans is part of Peter Biľak’s first superfamily, FF Eureka. Completed after the Serif version, the Sans was continually re-examined during its design phase, while it was being used in books, magazines, brochures, and posters, as well as on TV and even postage stamps. Unlike the serif version of FF Eureka, FF Eureka Sans ships with very narrow Condensed versions, too.
FF Eureka Sans works especially well for languages with accented characters. Many contemporary Western typefaces have large x-heights, which leave little room to accommodate accents. The result is that these are often too small and cramped; however, in many languages the accents are an integral part of the alphabet, and shouldn’t be reduced in size and importance! In order to maintain a proper rhythm in the text, Biľak adjusted the proportions of the typeface. The height of the ascenders and descenders is 1.7 times the x-height. This relatively small x-height leaves room for longer descenders and ascenders which in turn better accommodate accents and punctuation, it also gives the typeface its distinctive character. Because of the smaller x-height, FF Eureka Sans can be perceived as 1–2 points smaller than other text faces.
The proportions of FF Eureka are economic; letterforms are about ten percent narrower than in comparable text faces. This frees the user to letterspace text more generously, an important advantage for, as Biľak says, “looser spacing helps to avoid the typographic noise inside a text, and retains the individuality of letters.”
The FF Eureka Sans family includes true italics for all weights. The angle of slope has been minimized to only five degrees and, to differentiate them more from the Roman versions, the letterforms are somewhat condensed.
In 1997, FF Eureka won a prize at the National Design Award competition organized by the Slovak Design Center.
