Can You Change PDF Thumbnail Shapes in Acrobat Reader?
Question details
The user is asking whether it is possible to change the shape of PDF page thumbnails from a square frame to a custom rectangular shape in the Acrobat Reader navigation panel.
- Product
- Adobe Acrobat Reader
- Device & OS
- not provided
- Scenario
- Viewing and managing PDF page thumbnails in the left navigation pane.
- Observed behavior
- Acrobat Reader displays PDF page thumbnails in a fixed square layout within the navigation panel, and there is no built-in setting to customize this thumbnail frame shape.
Ensure you have Adobe Acrobat Reader open with a multi-page PDF document loaded so you can access and test the Page Thumbnails navigation pane.
Adjust the Navigation Pane to Change the Thumbnail Display Area
While Acrobat Reader does not allow changing the exact shape of the thumbnail frame, you can resize the navigation pane to scale the thumbnails and improve visibility.
Adobe Acrobat Reader forces a fixed aspect ratio for thumbnail containers. Because of this structural limitation, you cannot force a square thumbnail frame into a custom rectangular shape.
However, adjusting the width of the navigation pane forces the thumbnails to scale accordingly, which helps utilize your screen space more effectively.
Launch Adobe Acrobat Reader, open your PDF document, and click the 'Page Thumbnails' icon on the left-hand vertical toolbar to expand the navigation pane.
Hover your mouse cursor over the vertical dividing line between the thumbnail pane and the main document viewing area until the cursor turns into a double-sided arrow.
Click and drag the dividing line to the right to enlarge the thumbnails, or to the left to make them smaller. Release the mouse button once you reach your preferred size.

Frequently Asked Questions
Can I zoom in on a specific PDF thumbnail in Acrobat Reader?
You cannot zoom in on a single thumbnail. However, you can increase the size of all thumbnails simultaneously by dragging the border of the thumbnail navigation pane to the right, which expands the entire viewing area.
Why do my PDF thumbnails have large blank borders around them?
Acrobat Reader displays thumbnails within a fixed square container. If your document pages are rectangular (such as standard Letter or A4 dimensions), the software scales them to fit inside the square, which creates empty space or borders on the sides.
How do I completely hide the thumbnail pane while reading?
To hide the thumbnail pane and maximize your reading area, simply click the 'Page Thumbnails' icon on the left toolbar again, or click the small 'X' at the top of the thumbnail pane.
