Until Petrona loads, this sets Times New Roman in its place at 107.9% of its size, so running text keeps Petrona’s width and lines keep their height: nothing moves when it arrives.

Questions about Petrona
Answered from its licence, Google Fonts and each app’s own font list
Is Petrona free for commercial use?
Yes. Petrona is under the SIL Open Font License 1.1 , which allows commercial use at any scale, logos, websites, apps and PDFs included.
How do I download and install Petrona?
FontKind doesn’t host Petrona’s files: it comes free from Google Fonts . On its page there, choose Get font, then Download all, and unzip the file. It holds two variable files, one for the uprights and one for the italics, and a static folder with a file per style: install one set or the other, not both. On Windows or a Mac, double-click each font file and choose Install, then restart any app that was open, Word included.
Is Petrona in Microsoft Word?
Not until you install it: Petrona isn’t one of Microsoft 365’s cloud fonts. Installed, it is in Word’s font menu and PowerPoint’s. On Windows, its weights beyond Regular and Bold show as fonts of their own, such as Petrona Thin and Petrona Black. For someone who hasn’t installed it, turn on Embed fonts in the file in Word’s save options: its licence allows that.
Is Petrona in Google Docs?
Most likely. Search for Petrona under More fonts in the font menu of Docs; added there, it is in Sheets and Slides too.
