Rooftop Collection, designed by Interval Type, reinterprets 20th-century American humanist grotesques—such as Lining Gothic—through a contemporary tech-startup lens. The result is a 99-style collection spanning 8 typefaces, characterized by slightly squarish forms, squared ovals, and brutally styled characters including f, t, r, g, and y. Subfamilies address distinct use cases: Standard and Compact for running text, Ultra Condensed and Condensed for space-constrained headlines, Wide and Extended for display impact, Mono for code, and a three-axis Variable for animation.
A five-family collection by Interval Type comprising three serifs and two grotesques, originally developed as text and display serifs before expanding to include a monospaced serif and two sans serifs. The serif families draw from 18th–19th century fat faces; Oceanic Gothic references early grotesques of the late 19th and early 20th centuries; Oceanic Grotesk takes a mid-20th century modernist direction. All families share identical vertical metrics to enable mixed-family layouts. The collection's working name was Piranha, prompted by the predatory character of letterforms such as the lowercase c and e.
