How to Change the Font Size of Word Comment Balloon Text on Mac
Product
Microsoft Word
Device & OS
Mac
Scenario
Reviewing and editing documents using tracked changes and comments.
Observed behavior
Comment balloons display text in a font size that is either too small or difficult to read, and standard formatting options do not seem to alter their appearance directly.
Before you start

Ensure your document is not restricted from editing and note whether you have Word's 'Modern Comments' feature enabled, as this dictates how style changes appear on your screen.

Solution 1Recommended

Modify the Balloon Text and Comment Text Styles

Update Word's built-in document styles to change how comment balloons appear and print.

Microsoft Word controls the appearance of comments through specific built-in styles called 'Balloon Text' and 'Comment Text'. Modifying these baseline styles will adjust the font size for your document markup.

Please note that if you have the newer 'Modern Comments' interface enabled in Word for Mac, on-screen comments may not reflect these custom style changes. However, the modified formatting will still correctly apply when the document is printed or saved as a PDF.

1
Open the Styles Pane

Navigate to the 'Home' tab on the Word ribbon and click the 'Styles Pane' button on the far right to open the list of document styles.

2
Locate the Balloon Text Style

In the Styles Pane, find 'Balloon Text'. If it is not visible, click the 'List' drop-down at the bottom of the pane and select 'All Styles'.

3
Modify the Style Settings

Hover over the 'Balloon Text' style, click the drop-down arrow next to it, and select 'Modify Style' from the context menu.

4
Change the Font Size

In the Modify Style dialog box, click on 'Format' in the bottom-left corner, select 'Font', and choose your preferred font and size. Click 'OK' to apply the changes.

5
Update the Comment Text Style

Repeat steps 2 through 4 for the style named 'Comment Text' to ensure all your comment formatting remains consistent.

Modify the Balloon Text and Comment Text Styles
Modern Comments Limitation: Changes to the Balloon Text style will directly affect printed documents. However, the Modern Comments interface in newer Word versions overrides on-screen formatting, meaning you might not see the font size change visually on your monitor while editing.

Frequently Asked Questions

Why aren't my comment font sizes changing on the screen in Word for Mac?

If you are using newer versions of Microsoft Word with the 'Modern Comments' feature enabled, the application forces a standard on-screen format that overrides your custom styles. However, your selected 'Balloon Text' and 'Comment Text' styles will still be applied when you print the document.

Can I turn off Modern Comments in Word for Mac to see my font size changes?

Yes. You can disable Modern Comments by going to the top menu bar, selecting Word > Preferences > General, and unchecking 'Enable modern comments'. You must restart Word for the classic comments interface to take effect and display your custom font sizes.

Where do I find the 'Comment Text' style in Word for Mac if it is hidden?

Open the Styles Pane from the Home tab. If 'Comment Text' or 'Balloon Text' isn't visible, click the 'List' drop-down menu at the bottom of the Styles Pane and change the view from 'Recommended' or 'In Current Document' to 'All Styles'.
