Use the corporate brand’s own typography reference
Meta’s partnership guidance, updated July 2026, names Optimistic regular for a Meta-hosted line of credit. It separately names Facebook Sans when Facebook is the host. That is a concrete brand-role specification, not proof that every Meta-owned app uses one font for every screen. It also concerns the corporation, rather than the unrelated FF Meta family.
Determine the host before setting a credit line
The guidelines distinguish the communication’s host from its featured guest and say the host’s identity guides typography. For an authorized partnership document, record which brand owns the communication and whether it supplies the complete lockup or only a logo asset. Do not choose Optimistic simply because Meta is mentioned somewhere in the text. For an independent layout exercise, use fictional organization names and compare a stable credit line with the main event heading; keep the actual family and role documented.
Keep the supplied wordmark distinct from typed text
Meta’s October 2021 design account says its wordmark uses the company typeface introduced in 2019, while separately describing the continuous-loop symbol. Do not turn that into a claim that typing the company name reproduces the complete logo asset. Inter and Source Sans 3 here are independent comparisons, not Optimistic files. The homepage’s copyable styled text changes Unicode characters; it does not install Meta’s corporate family or change the font settings in Facebook, Instagram or another app.
Your questions, answered.
What font does Meta name in its partnership typography guidance?
For a Meta-hosted line of credit, the July 2026 guidance names Optimistic regular in sentence case. It names Facebook Sans for the Facebook-hosted example.
Is FF Meta the same as Meta’s corporate font?
No. This query concerns Meta’s corporate brand, whose guidance names Optimistic. FF Meta is a separately named type family, covered in its own guide.
