How to Resize the Word Preview Pane in Windows
Product
Microsoft Word
Device & OS
Windows
Scenario
Trying to view document previews in File Explorer, the Word Open dialog, or Print Preview.
Observed behavior
The preview pane shrinks to a narrow strip on the right side and cannot be dragged, resized, or repositioned.
Before you start

Determine exactly where the preview issue is occurring: in Windows File Explorer, the Word 'Open' dialog box, or the Print Preview screen, as the solution depends on the specific interface.

Solution 1Recommended

Enlarge the Open Dialog or File Explorer Window

Use this solution if the preview pane is too narrow within Word's 'Open' dialog box or Windows File Explorer.

In many cases, the preview pane in the 'Open' dialog or File Explorer scales dynamically with the overall window size. If the main window is too small, the preview pane will compress into a narrow strip.

1
Open the File Explorer or Dialog Box

Launch Windows File Explorer or open Microsoft Word and press Ctrl + O, then click 'Browse' to launch the Open dialog.

2
Maximize the Window

Click the Maximize square icon in the top-right corner of the window to make it full screen. The preview pane width should increase proportionally.

3
Manually Drag the Borders

Hover your mouse pointer over the vertical line separating the file list and the preview pane until it becomes a double-headed arrow, then click and drag it to the left to widen the preview area.

Enlarge the Open Dialog or File Explorer Window
Preview Handlers: If the pane expands but no preview loads, ensure that 'Show preview handlers in preview pane' is enabled in your File Explorer Folder Options.

Frequently Asked Questions

How do I turn on the preview pane in Windows File Explorer?

Open File Explorer, click on the 'View' tab at the top of the window, and select 'Preview pane' in the Panes section. Alternatively, you can toggle it on and off by pressing Alt + P on your keyboard.

Why does my Word document say 'Preview not available'?

This happens when the preview handler for Microsoft Word is disabled or corrupted. To fix this, open File Explorer, go to View > Options > Change folder and search options, select the View tab, and ensure 'Show preview handlers in preview pane' is checked. If it still fails, repairing your Office installation usually restores the preview handler.

Can I zoom in on the File Explorer preview pane?

No, the File Explorer preview pane does not have a built-in zoom feature for Word documents. It only scales according to the physical width of the pane. To see the document larger, you must click and drag the pane border to widen it, or open the document directly.
