What Font Does Grammarly Use?
The Grammarly font question comes up a lot because the brand’s clean green identity feels deliberate and ownable — but Grammarly doesn’t publish a detailed type spec the way some companies do, so part of the answer involves reading the brand carefully rather than quoting a press release. What we can say confidently: Grammarly’s marketing identity uses a custom sans-serif, and its product UI leans on familiar, highly legible sans-serifs. Below we cover both and the free alternatives. For how other software brands approach type, see our hub on famous brand fonts.
What font does the Grammarly logo use?
Grammarly’s green wordmark uses a custom sans-serif letterform rather than an off-the-shelf font you can download. It’s clean, rounded, and approachable — friendly enough to feel human, neutral enough to feel trustworthy for a writing-assistant brand. Because the wordmark is custom-drawn and trademarked, you won’t find an exact “Grammarly font” file, and any version on a free-font site is an unofficial imitation. The closest way to echo it legally is a humanist sans with open, rounded letterforms.
What font does the Grammarly app use?
Inside the product — the editor, suggestions panel, and account screens — Grammarly prioritizes readability with clean sans-serif typography, typically standard system or web-safe sans-serifs. That makes sense for a tool whose entire job is helping you read and edit text: the interface type needs to be invisible and effortless, never decorative. As with most large web apps, exact font stacks and fallbacks can change between surfaces and over time, so we describe Grammarly’s UI as “a clean sans-serif system” rather than pinning it to one fixed file.
Is the Grammarly font custom or off-the-shelf?
The brand-level identity — the wordmark and marketing headlines — appears to use a custom or proprietary sans-serif tuned to Grammarly’s personality. The product UI, by contrast, leans on common, highly legible sans-serifs rather than a bespoke face. This is a typical modern split: invest in a distinctive face for the brand layer, and use dependable, fast-loading system sans for the interface. We hedge slightly here because Grammarly hasn’t published a full public type spec, so treat the brand face as custom and the UI as standard humanist/neo-grotesque sans.

Why does Grammarly use a clean sans-serif?
For a product built entirely around text, typography is the user experience. A clean, neutral sans-serif keeps the interface calm and legible so your writing — not the UI — stays in focus, and it signals the trustworthy, professional tone a writing assistant needs. The custom brand face adds just enough personality at the marketing layer to feel ownable and friendly without ever competing with the words on screen. It’s a restrained, confident type strategy that fits the brand’s “clear communication” mission.
How to recreate the Grammarly look
To echo Grammarly’s identity for free, set both your interface and body text in Inter or Open Sans, keep weights in the regular-to-semibold range, and use generous line spacing for a calm, readable feel. Lean on Grammarly’s signature green as a single accent against plenty of white space, and keep decoration minimal — the whole point is clarity.
If your brand needs a distinctive face of its own, note that Grammarly’s wordmark is custom and trademarked, so use these free alternatives to build your own identity rather than imitating Grammarly. Our font pairing guide shows how to pair a humanist sans for UI with a complementary display or serif face if you want more contrast.
