Brand font guide
What font does Facebook use?
Facebook sets its logo and interface in Facebook Sans, a sans-serif typeface by in-house / Eric Olson. A humanist grotesque created with Eric Olson; its open, friendly forms echo the older Klavika-style wordmark.
Free stand-ins
Free Facebook Sans alternatives
Facebook Sans is a commercial typeface. These open-source Google Fonts capture its character and are free for personal and commercial use.
How we know it is Facebook Sans
The identification comes from measuring real letterforms — relative x-height, stem weight, stroke contrast and letter width — the same four metrics the font finder uses on any screenshot you upload. Facebook Sans has a signature silhouette, and the free fonts listed above were matched against it on those same numbers.

You can set your own site in any of the free alternatives above and get remarkably close to the Facebook feel — same weight, similar x-height and spacing — without paying for a commercial licence. Each card links to a detail page with the ready-to-paste CSS embed.
