Fix Word Track Changes Balloon Position Overlapping With Comment Threads

When you use Track Changes and review comments in Word, balloons on the right side of the document can overlap with comment threads, making it impossible to read either element clearly. This happens because Word places Track Changes balloons and comment bubbles in the same margin area, and the layout does not automatically adjust when both features are active. In this article, you will learn why the overlap occurs and how to resolve it by changing how Word displays markup and comments.

Why Track Changes Balloons Overlap With Comment Threads

Word uses the right margin of a document to display two types of annotations simultaneously. Track Changes balloons show insertions, deletions, and formatting changes. Comment threads appear as colored bubbles with reply chains. Both elements share the same horizontal space. When a document contains many changes and comments, the margin cannot fit all items without overlapping. The problem becomes worse when comment threads contain multiple replies because each reply adds height to the bubble. Word does not automatically resize or reposition the balloons to avoid the overlap. The result is a cluttered margin where text from a balloon covers text from a comment thread, or vice versa.

How Word Allocates Margin Space

Word assigns a fixed-width margin area on the right side of the page for balloons and comments. The width is determined by the document layout settings and the zoom level. When you zoom in, the margin shrinks, making overlap more likely. When you zoom out, the margin expands, but the number of visible items may increase because more lines of the document appear on screen. Word does not prioritize one annotation type over the other; it simply places them in the order they were inserted. This means an early comment can occupy space needed for a later Track Changes balloon.

Print Layout vs Draft View Behavior

The overlap occurs almost exclusively in Print Layout view, which is the default view for reviewing documents. In Draft view, Word shows Track Changes marks inline by default and does not display comment threads in the margin. However, Draft view does not show the final page layout, headers, footers, or graphics. Switching to Draft view is a temporary workaround but not a solution for users who need to see the formatted page.

Steps to Fix Balloon and Comment Overlap

The most effective fix changes how Word displays Track Changes markup. You can move all revisions inline, which removes balloons from the margin and leaves only comment threads. Follow these steps.

1. Open the Review tab
   Click the Review tab on the ribbon at the top of the Word window. This tab contains all commands related to Track Changes and comments.
2. Locate the Tracking group
   In the Review tab, find the Tracking section. It is usually the third group from the left, containing buttons labeled Track Changes, Display for Review, Show Markup, and Reviewing Pane.
3. Click Show Markup
   Click the Show Markup button. A dropdown menu appears with options for Balloons, Specific People, Highlight Updates, and other markup filters.
4. Select Balloons > Show All Revisions Inline
   Hover over the Balloons option in the dropdown. A submenu appears with three choices: Show Revisions in Balloons, Show All Revisions Inline, and Show Only Comments and Formatting in Balloons. Click Show All Revisions Inline. Word immediately moves all Track Changes markers into the document body. Insertions appear as underlined colored text, deletions appear as strikethrough text, and formatting changes appear as colored brackets. The right margin now contains only comment threads, which no longer overlap with any balloons.
5. Adjust zoom if needed
   If comment threads still appear crowded, use the zoom slider in the bottom-right corner of the Word window to zoom out. A zoom level between 80% and 100% usually provides enough margin width for long comment threads without overlap.

Alternative: Show Only Comments and Formatting in Balloons

If you prefer to keep some information in the margin, choose Show Only Comments and Formatting in Balloons from the same Balloons submenu. This setting keeps formatting change balloons in the margin but moves text insertions and deletions inline. The margin then contains fewer balloons, reducing the chance of overlap with comment threads. This option is useful when you need to see formatting changes at a glance but do not need to see every inserted or deleted word in a balloon.

Alternative: Use the Reviewing Pane Instead of Balloons

The Reviewing Pane is a separate panel that lists all tracked changes and comments in a table format. To use it, click Reviewing Pane in the Tracking group and choose Reviewing Pane Vertical or Reviewing Pane Horizontal. The pane appears on the left side or bottom of the document window. When the Reviewing Pane is open, you can set Balloons to Show All Revisions Inline and still see a complete list of changes in the pane. This combination eliminates margin clutter entirely.

If Word Still Has Issues After the Main Fix

After applying the inline setting, some users may still experience visual problems. The following issues and their solutions cover the most common remaining scenarios.

Comment Threads Still Overlap With Each Other

When a document has many long comment threads, the bubbles can overlap vertically in the margin. This happens because Word does not allow comment bubbles to extend beyond the page boundary. To fix this, reduce the number of visible comments. Click Show Markup and uncheck Comments. Only the comment markers (colored brackets) remain in the document body. Alternatively, resolve or delete completed comments by right-clicking a comment and selecting Resolve Thread or Delete Thread.

Inline Markup Makes the Document Hard to Read

Some users find inline markup distracting because insertions and deletions appear directly in the text. To improve readability, set Display for Review to Simple Markup instead of All Markup. Simple Markup shows a red vertical line in the left margin to indicate a change but does not show the changed text inline. Click the Display for Review dropdown in the Tracking group and select Simple Markup. The comment threads remain in the right margin, and the document body looks clean.

Track Changes Balloons Reappear After Saving and Reopening

Word remembers the Balloons setting per document. If you save the document with Show All Revisions Inline and later reopen it, the setting should persist. If balloons reappear, another user may have changed the setting, or the document was opened in a version of Word that does not support the inline setting. To reapply the fix, repeat the steps in the main section above. You can also save the setting as a default template by modifying Normal.dotm, but that change applies only to new documents.

Balloons Inline vs Balloons in Margin: Comparison

Item	Show All Revisions Inline	Show Revisions in Balloons
Margin content	Comment threads only	Balloons and comment threads
Insertion display	Underlined colored text in body	Balloon in margin
Deletion display	Strikethrough colored text in body	Balloon in margin
Formatting change display	Colored brackets around text	Balloon in margin
Overlap risk	None between changes and comments	High when many changes and comments exist
Best for	Reviewing comments without margin clutter	Seeing all changes at a glance in the margin

Overlapping Track Changes balloons and comment threads occur because both elements share the same margin space in Print Layout view. By switching to Show All Revisions Inline, you remove balloons from the margin and keep only comment threads visible. For documents with many comments, use Simple Markup to reduce visual noise, or use the Reviewing Pane for a complete list of changes. These settings give you full control over how Word displays revisions and comments without sacrificing readability.
