Aptifer Sans and Aptifer Slab are two 21st century typeface families created by Mårten Thavenius. Each family has seven weights, in roman and italic respectively, making 28 font styles in total.

A heritage from two design traditions can be seen in Aptifer. One is the robust American gothic typefaces, like M. F. Benton’s, from around 1900. This is combined with the openness and legibility that comes from the humanist tradition.

The sans serif part of the family, Aptifer Sans, is designed without excessive details disturbing the reading. Its sibling, Aptifer Slab, with its wedge slab serifs is more eye-catching but still suited for text settings. The italics fit well into the text flow of the roman. They are a bit narrower than the roman and have cursive characteristics.

Both Aptifer Sans and Aptifer Slab are highly legible typefaces and can be used both in print and on screen.
