Some font names are too long to be displayed in Word's font-selection box in the ribbon. (I'm on Windows and have the same issue with any post-ribbon version of Word. I suspect the same issues exist in the other Office programs.) This is very often the case with professional fonts such as those synced from Adobe Typekit. For example, here's how "FreightText Pro Semibold" displays in the ribbon:
The view is the same if you view the right-click context menu or add the font selector to the Quick Access Toolbar. Unfortunately, even going into the drop-down selection menu does not tell you which specific font is currently in use:
If the font you're trying to identify appears in the recently used fonts list, it does highlight the font in the list:
This is pretty limiting: the font has to be recently used, and the highlighting goes away with a twitch of the mouse. So the only consistent way I have of knowing what font is in use is to select and copy the font name and then paste it somewhere where I can read it. As a workaround, I could shorten the names in the font files, but that won't work for Typekit files that are synced rather than traditionally installed.
The ideal solution for me would be to remove the "Change Case" and "Clear All Formatting" buttons from their place in the ribbon and allow the font selector and font size menus to fill that horizontal space. By following the instructions at https://support.office.com/en-us/article/Customize-the-ribbon-in-Office-00f24ca7-6021-48d3-9514-a31a460ecb31 (basically right-click anywhere in the ribbon, choose "Customize the Ribbon," and make selections), I was able to create a new group, but unfortunately, the font selector doesn't resize along with the window size even though other commands do (and it doesn't matter if the font selector is the only command in the group):
I think any solution will be less than ideal, but I'm open to suggestions! I just want to see at a glance what font I'm using.
