Optima can be set within a wide choice of line spacing values – from very tight to very open. In fact, there are few limits to the amount of white space that can be added between lines of text. Optima also benefits from a wide range of letter spacing capability. It can be set quite tight, or even slightly open – especially the capitals.
Optima is also about as gregarious as a typeface can be. It mixes well with virtually any serif design and a surprisingly large number of sans serif faces.
The Optima family is available in six weights, from roman to extra black, each with an italic counterpart. In addition, the family is available as a suite of OpenType® Pro fonts, providing for the automatic insertion of small caps, ligatures and alternate characters, in addition to offering an extended character set supporting most Central European and many Eastern European languages.
