Open Sans has been a workhorse of web design for over a decade, prized for its humanist warmth, generous x-height, and the way it stays legible at nearly any size on screen.

- Styles: 14 styles (7 weights plus italics)

Cabin
Casual, humanist text with rounded warmth

Straightforward text built for government and civic sites

Its very plainness is the point; it disappears into the content rather than asking for attention, which is exactly what Open Sans does so well.
- Language support: Latin, Latin Extended, Vietnamese

IBM Plex Sans
Corporate-friendly text with subtle technical edge
IBM Plex Sans

Pairing and usage tips
Most of these fonts are humanist sans faces, so they pair beautifully with a serif for headlines if you want more contrast between display and body text.
If you are swapping Open Sans out of an existing design system, test the replacement at your smallest UI size first. Fonts like Inter and Public Sans were built specifically to hold up there, while some of the warmer options can blur slightly.
For multilingual projects, prioritize Noto Sans or PT Sans, since both were designed with broader script coverage from the start.
Stick to two families per project: one for body text from this list, and one distinct display face for headings.
Any of these free Google Fonts can step in for Open Sans without asking your readers to relearn how to read your site. The right pick comes down to how much warmth, neutrality, or technical polish your particular project needs.
