The Renaissance astronomer Johannes Kepler tied his interests in optics and astronomy together and invented an improved version of the refracting telescope. It's fitting that the typeface that bears his name was designed with an eye to optical purity as well as design.
Created by Adobe type designer Robert Slimbach in the tradition of classic modern 18th-century typefaces, the Kepler™ font family includes four optical size variations that have been optimized for use at specific point sizes. Intended sizes vary by family, but the general size ranges include Caption (6-8 pt), Regular (9-13 pt), Subhead (14-14) and Display (25-72pt).
Although modern typefaces are generally known for their intellectually-based qualities, the Kepler font's modernism is conveyed in a more humanistic manner. On first glance, It's as elegant and refined as many of the most popular 18th century typefaces so popular with printers and typesetters. It's warmth and energy are delivered with a hint of old style proportion and calligraphic detailing. But the concept behind the Kepler font is firmly rooted in the modern technology around us today.
