Microsoft Office changed the font size and style to Calibri 11 pt in Office 2007. For a lot of users, the size is too small, and some of you might want to change the font style as well. If you’re using the new versions of Microsoft Office — either 2013 or the 2016 preview, here’s how to set the default font size and style to what works best for you.
Change Font Size and Style in Microsoft Word
First, launch Word in Microsoft Office 2013 or 2016 and use the keyboard shortcut Ctrl+Shift+F to open the Font dialog box shown below. Here is where you can change the default font style, size, effects, and even the color if you want.
After you choose your settings, make sure to click the Set As Default button in the lower left corner. If you only click OK, it will change the font for this document only.
After making your selections you’ll get a confirmation dialog box where you want to select “All documents based on the Normal template” and click OK.
Now every time you open a document, the default font size and style will be exactly what you set it to. It’s worth noting that you can use the same steps in Office 2010, too.
Unlike changing the Office color theme, which changes all of the apps in the Office suite, you need to change the default font in each app individually. For example, here’s how to change the default Outlook 2010 font.
