Amplitude uses typography to express brand personality and has some ranges within our product and marketing materials. Gellix is used as our display typeface and IBM Plex is our workhorse body typeface.
Display and headline copy—Gellix
Gellix is the typeface used for all of Amplitude’s display typographic treatments. Though there are more weights available in the Gellix family, Amplitude uses only Light, Regular, Medium, and Semibold. If a user or machine is unable to use Gellix, use an alternative typeface—Arial—in its place.
Usage—Gellix
Review our foundational web point size and leading, built to ensure greater consistency between applications and communications.
Please use no more than three type sizes per layout. Avoid using multiple sizes and weights within a single line or section of copy.
Body copy—IBM Plex Sans
IBM Plex Sans is the typeface used for all of Amplitude’s body copy typographic treatments. Though there are more weights available in the IBM Plex Sans family, Amplitude uses only ExtraLight, Light, Regular, Medium, and Semibold. If a user or machine is unable to use IBM Plex Sans, use an alternative typeface—Arial—in its place.
Usage—IBM Plex Sans

Please use no more than three type sizes per layout. Avoid using multiple sizes and weights within a single line or section of copy.
Fallback fonts
With technology and access limitations to our primary display font Gellix, we have backup recommendations for web, digital, and other purposes. For example, Gellix is not available in Google Slide presentations, so we recommend our first fallback—Poppins. Sizes and weights should match the earlier guidance based on usage and location.
Poppins
A geometric open source font available through Google, Poppins should be the primary replacement for Gellix when needed. Available directly through Google workplace apps or for download on Google Fonts.
Helvetica
For use only when prior options are unavailable, Helvetica is the most suitable web-safe font generally available to anyone. Example uses include html emails where custom fonts are not available.
