Inter (typeface)

Lato (typeface)
Lato is a humanist sans-serif typeface designed by Łukasz Dziedzic and released in 2010. It was commissioned by a Polish bank, then cancelled and published under the Open Font License. As of August 2018, it appeared on over 9.6 million websites and ranked third on Google Fonts by usage. It has been applied in physical media including election billboards and information signs, and adopted by Save the Children for its logotype since 2022.

Source Sans

IBM Plex
IBM Plex is a corporate typeface designed to replace Helvetica across IBM’s global communications. Its rationale is financial and ideological: open-source licensing eliminates licence fees; typographic decisions reject expressive or historical categories in favour of functional clarity. It delivers a coherent, documented system — but only within the narrow frame of IBM’s internal brand requirements.

Open Sans
Open Sans is a functional, open-source humanist sans-serif designed by Steve Matteson for Google in 2011. It prioritises screen legibility through wide apertures and large x-height, supports Latin, Greek, Cyrillic (897 glyphs), gained Hebrew and variable font support in 2021, and manifests publicly via a Google Easter egg. It does not extend beyond those scripts. Its influence lies in normalising open-source, cross-platform typography — not aesthetic innovation.

Roboto
Roboto is a functional, open, and pervasive sans-serif typeface family designed by Christian Robertson for Google in 2011. It succeeded by solving a narrow problem well — legibility on early Android screens — then scaled through permissive licensing and platform integration.
