Phyllis has been using the Comments tab (on the Review tab of the ribbon) to correct student papers for her class. She wonders if there is a way to change the default font style and size for the comments.
As with many other formatting-related issues in Word, you can control how your comments appear based on built-in styles. Change the way the style is defined, and you change how your comments appear.
To change how the text in your comments are formatted, follow these steps:

Figure 1. The Style Pane Options dialog box.

Figure 2. The Modify Style dialog box for the Comment Text style.
At this point, any comments in your document should reflect whatever formatting you specified in step 10—with one exception. If you changed the font size to something different (step 10), then that is not applied to the comments. Why Word ignores the font size is unknown, and quite frustrating. (It certainly won't solve all of Phyllis's desires.)
Some people report that you can modify the size of the font in the comments by using modifying the Balloon Text style. For instance, this YouTube video shows how to do exactly that:

The problem is that such approaches will only work in older versions of Word. It appears, in fact, that it will only work in versions that don't use the newer threaded comments. If you are using Word 2019, 2021, 2024, or Microsoft 365, then there appears to be no way to adjust the size of the comment text.
That being said, all the other attributes of your text can be changed as described in the steps above. There are, in reality, three different styles you may want to modify, following the steps already outlined. These styles control different elements of the comments:
When all is said and done, the shortest answer to Phyllis' question is to change the Comment Text style to reflect how you want the comments to appear, except for text size.
