Typography — fonts

Fonts do a lot of brand work quietly. Get them right once and every room automatically feels on-brand.

⚠️ Requires org role Admin. Go to Settings → Branding → Typography.

Three font slots

Katalyz lets you pick three fonts, each with its own role:

Font slot	Used for
Navbar font	Navigation, section labels, tabs
Headings font	Section titles, block titles, large callouts
Text font	Body copy — paragraphs, lists, descriptions

Most brands use 2 fonts in practice: one for display (headings) and one for body text. Katalyz supports 3 slots so you can differentiate navigation from content if your brand calls for it — otherwise, use the same font for navbar and headings.

Default font size

You also set a default font size for body text across rooms. This propagates through all rooms unless a specific block overrides it.

Recommended: 15–16px for comfortable readability on desktop. Smaller feels cramped; larger can feel shouty.

Adding a font

Click + Add font in the Typography section. You have two sources:

Google Fonts

The easy option. Search the Google Fonts library (over 1,500 fonts), pick one, and it's added. Weights and styles are handled automatically.

Good Google Fonts for Sales rooms: Inter, Poppins, Manrope, DM Sans, Plus Jakarta Sans, Lexend, Roboto, Open Sans.

Custom fonts

Upload your own font files — useful if your brand has a licensed typeface not on Google Fonts.

Upload the files for each weight/style combination you need:

Regular (400)
Medium (500)
Bold (700)
Italic variants if your brand uses them

Supported file formats: .woff2, .woff, .ttf, .otf.

Once uploaded, the custom font appears in the picker for each of the three slots.

Licensing

Custom fonts must be licensed for web use. If you're not sure whether your font license covers Katalyz, check with your licensor — or use a Google Font, which is always free and permissive.

Best practices

Don't mix more than 2 typefaces in a single brand system. One for headings, one for body is usually enough.
Check legibility at small sizes — some fonts look great in headlines and terrible in 13px body copy.
Avoid decorative fonts for body text — they slow reading.
Preview changes in a real room before saving. Fonts read differently in context than in a settings preview.
