Text Font

Defines the typeface and style to set the text in.

The value may be either a CSS-style category, or an explicit font name. The possible CSS names are serif, sans-serif, monospace, cursive, fantasy. For an explicit typeface, use the name instead. Use txt-font[N] to override this for a specific text layer — bare txt-font applies to every layer by default.

To make the type style bold or italic, append the desired options as a comma-separated list. For example: txt-font=sans-serif,bold,italic.

If you omit txt-font, text renders in HelveticaNeue.

Search the supported typefaces below. Each result previews the typeface as the Rendering API actually draws it. Typefaces for non-Latin writing systems are previewed with a specimen in their own script. The same list, alongside the Video API’s separate font set, is on the Supported Fonts reference page.

Custom Fonts

txt-font also accepts fonts you upload in the dashboard, either account-wide or scoped to selected Sources, on images and on video text overlays. See Custom Fonts to upload fonts and choose their scope.

Use the txt-font value shown on the Fonts page. The family name is the regular file; txt-weight and txt-style switch to the bold and italic files you uploaded:

Any other weight is its own font, with its own value:

• A font also answers to the full name and PostScript name in its file. Case, spaces and punctuation don’t matter.
• A custom font takes precedence over a built-in typeface with the same name.
• If no custom font matches, or the font isn’t enabled for the Source, txt-font falls back to the built-in typeface with that name, then to the default font.
