We always recommend changing the default settings of any Office application to your preferences, which can save a lot of time (and annoyance!). In the video above, you’ll see a quick demo of changing the font settings for OneNote 2013. You can also follow these steps:

1. Click the File tab, and select Options.
2. In the General tab, go to the Default font section and change the settings according to your preferences.
3. Click OK.
