Pages

Change the font or font size in Pages on Mac
You can change the font and font size of text and replace a font everywhere it occurs in your document.
Note: To change the default font used for new documents, see Set a default font.
When you open a document that uses fonts not installed on your computer, a missing font notification appears briefly at the top of the page. To replace the missing font, click the notification.
If you have the missing font and want to install it on your computer, use Font Book, available in the Applications folder on your Mac (see the Font Book User Guide for instructions).
If you choose a replacement font for the document, then later install the missing font, your document continues to use the replacement font until you replace it with the font you installed.
