Change fonts in Letters

Say goodbye to struggling with finicky font pickers. With Font Switch you can change fonts in Letters directly from Typeface.


Click on the text field in the top right corner to make it active, or double click on some text in the document. Then drag a font from Typeface to your document. Typeface changes the font of all the text in the field.


macOS 10.14+


Typeface makes the targeted font automatically available to Letters. The font will be temporarily activated, which means that it will be deactivated when you close Typeface (depending on your Preference settings). This allows you to freely try and switch fonts and you don't have to worry about cleaning up later.

If you want to keep the font persistently activated, you can click on the activation indicator to deactivate the font. Then click it once more to persistently activate the font.

Example: Switching fonts in Sketch

Initial setup

1. Drag and drop a font from Typeface to Letters

When you drag a font to Letters Typeface will check if it has the necessary permission to switch fonts. The following steps guide you through setting these permissions. If you've already given permission the font of the currently selected text in Letters will be changed right away.

2. Allow Typeface to control other apps using Accessibility features

Security restrictions in macOS prevent communication between apps by default. A dialog to request permission will automatically show up. Choose Open System Preferences to view the current Accessibility settings. Then click the lock icon to make changes and enable the checkbox next to This will grant Typeface access to switch fonts in Letters.

Giving permission has to be done only once. If you have previously given Typeface access you don't have to give access again and the dialog will not show up.
