How to Stop Word for Mac from Opening the Reviewing Pane Automatically
Product
Microsoft Word for Mac
Device & OS
macOS
Scenario
Editing or reviewing a document that contains comments or tracked changes.
Observed behavior
The left-side Reviewing pane automatically pops open to display comments, even when there are only a few short comments, disrupting the document workspace.
Before you start

Make sure you know whether you are using the modern Comments pane or the legacy Reviewing pane, as fixing the automatic pop-up behavior requires adjusting settings specifically for legacy markup balloons.

Solution 1Recommended

Adjust Track Changes Balloon Settings

Prevent the legacy Reviewing pane from opening by increasing the markup-area width so comments fit comfortably within the document margin.

Word for Mac automatically opens the Reviewing pane when there isn't enough space in the right margin to display comments or markup balloons. By manually increasing this width, you can keep the pane hidden.

1
Open Word Preferences

Click on 'Word' in the top-left Apple menu bar and select 'Preferences' from the dropdown menu.

2
Access Track Changes

In the Preferences window, click on 'Track Changes' located under the Output and Sharing section.

3
Modify Balloon Width

Locate the 'Balloons' section at the bottom. Adjust the 'Preferred width' setting to a larger value to give the markup area more space.

4
Restart and Verify

Close the Preferences window, restart Microsoft Word, and open your document to confirm the Reviewing pane no longer opens automatically.

Space Allocation: Providing adequate width for balloons ensures all comments stay securely in the margins without triggering the side pane.

Frequently Asked Questions

What is the difference between the Reviewing pane and the Comments pane?

The Reviewing pane is a legacy feature that typically opens on the left side to show all tracked changes and comments when they cannot fit in the margins. The modern Comments pane typically opens on the right and is specifically designed for threaded conversations.

Why does the Reviewing pane open even for short comments?

This usually happens if your markup-area width in Preferences is set too narrow for the display, or if you are using legacy comment formats instead of modern threaded comments.

How do I close the Reviewing pane manually?

You can close it by clicking the 'Reviewing Pane' button on the 'Review' tab in the ribbon, or by simply clicking the 'X' at the top corner of the pane itself.

Will restarting my Mac fix pane display issues in Word?

Yes, a simple system restart can often resolve temporary UI glitches in Word for Mac, especially if they began occurring immediately after installing a recent macOS or Office update.
