Font sizes and styles are a great way to make your doc stand out.
You can configure font sizes and styles at the page-level. To get there, hover over the top of your page canvas to expose the word ‘Options,’ and then click it to open the Page Options right-side panel.
If you want to apply your font settings as the default for all new pages in a doc, you can toggle from ‘This Page’ to ‘Settings.’ If you also want to apply your choices to all existing pages in a doc, click the “Apply to all pages” option and proceed.
