FF Kievit

FF Kievit is a humanist sans-serif typeface designed by Mike Abbink, Christian Schwartz and Paul van dan Laan, published by FontShop International, and released in 2001. It currently has 18 styles, including 9 weights and true italics, as well as small caps and text figures. It is described as being "ideal for large projects in print and on screen." It features large x-height as well as open apertures, which are optimised for small text sizes. It takes inspiration from a number of classic sans-serif typefaces, such as Frutiger and Univers, and humanist serif typefaces including Garamond.

Sans-serif faces work well for headings, captions, children's books and modern nonfiction. For long-form body text in print, most designers still prefer a serif.
