Roboto Slab
Designed by Christian Robertson at Google, Roboto Slab brings the mechanical clarity and geometric skeleton of the Roboto family into the slab-serif genre with sturdy rectangular serifs and open letterforms. Its dual nature — combining rational structure with friendly, open curves — ensures strong digital legibility at any size, making it a natural fit for tech brands, content-heavy websites, and editorial layouts. Available as a variable font with weights from Thin to Black, it pairs seamlessly with Roboto Sans for cohesive typographic systems.
Zilla Slab
Commissioned by Mozilla and designed by Peter Bilak and Nikola Djurek of Typotheque, Zilla Slab is a contemporary slab serif built with smooth curves and true italics that convey both industrial sophistication and friendly approachability. It serves as Mozilla's core brand typeface and works exceptionally well for tech companies, open-source projects, and editorial headlines that need authoritative yet accessible typography. Available in multiple weights with a companion Highlight variant, it brings a distinctive identity rooted in the open web movement.
Bitter
Designed by Sol Matas of Huerta Tipografica, Bitter is a contemporary slab serif built from the pixel grid up, specifically optimized for comfortable on-screen reading. Its slightly heavier-than-normal regular weight, large x-height, and square serif terminals create strong paragraph color and rhythmic flow in long-form text, making it ideal for blogs, news sites, and content-driven brands. The humanistic touches in its letterforms soften the geometric rigor, balancing readability with personality.
Rokkitt
Initiated by Vernon Adams and later completed by Kalapi Gajjar with a full set of nine weights, Rokkitt is a geometric slab serif inspired by classic Egyptian typefaces like Rockwell from the early twentieth century. Its clean geometric forms and sturdy serifs make it effective for display use in headings and headlines, while remaining legible enough to serve as an alternative to sans-serifs at text sizes. Well-suited for vintage-inspired brands, editorial design, and any project seeking a bold, structured presence with historical character.
Arvo
Designed by Estonian typographer Anton Koovit, Arvo is a geometric slab serif with a near-monolinear stroke and a touch of contrast added for screen legibility. Its high x-height, mix of straight and curved edges, and print-plus-web design philosophy make it highly readable across both digital and physical media, ideal for professional brands, editorial content, and corporate identities. Available in four styles (Regular, Italic, Bold, Bold Italic), it balances mechanical precision with approachable warmth.
