How to Stop Acrobat from Resetting Window Layout When Opening PDFs
Question details
The user needs to prevent their PDF viewer from automatically resetting the workspace layout, resizing the window, and reopening the right sidebar when opening documents.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Opening multiple new PDFs or restoring a group of tabs after a software crash or restart.
- Observed behavior
- The application constantly changes the selected view, resizes the main window, and reopens the right-hand tool pane, overriding the user's preferred layout settings.
Before adjusting your workspace settings, ensure you have saved any open PDF forms and check if there are pending updates for your PDF software, as bugs related to workspace restoration are often patched in newer releases.
Disable Automatic Tab Restoration and Hide the Tools Pane
Prevent the software from automatically opening the right sidebar and resetting your layout by adjusting its document preferences.
PDF applications often default to displaying tool panes to promote additional features. Adjusting the viewing preferences forces the application to remember your chosen layout instead of resetting it every time a document is launched.
Launch your PDF reader and navigate to 'Edit' in the top menu, then select 'Preferences' (or press Ctrl+K).
Select 'Documents' from the left-hand categories menu.
Uncheck 'Restore last view settings when reopening documents' to prevent layout changes, and check 'Remember current state of Tools Pane'.
Click 'OK', manually close the right sidebar, and restart the application to verify that your preferred layout remains consistent.

Repair Corrupted Application Installation
If the layout keeps resetting due to corrupted configuration files from a recent crash, running the built-in repair tool can restore normal behavior.

Frequently Asked Questions
Why does the right sidebar keep opening when I view a PDF?
Many PDF readers default to showing the tools pane to provide quick access to premium features or menus. You can usually disable this by going to your application's Preferences under the 'Documents' tab and checking the option to remember the current state of the tools pane.
Can I stop my PDF viewer from reopening previously closed tabs after a crash?
Yes. When the application restarts after a crash, it typically prompts you to restore tabs. If you decline the prompt or disable the 'Restore last view settings' option in the settings menu, it will open with a fresh, empty layout.
Is there a way to lock my preferred window size for all PDF files?
Most standard PDF viewers do not have a strict 'lock window size' feature. However, configuring the software to ignore a document's native view settings and maximizing the window before closing the application usually forces it to remember your preferred dimensions.
