Changing default page view in Adobe Acrobat

Posted by jpluimers on 2026/03/02

Being so used to open PDF files using MacOS Preview – which remembers the last view settings and re-applies that when opening a new document, it took me a while to figure out that in both Adobe Acrobat and Adobe Reader (formerly Acrobat Reader) you have to set it in the preferences using Ctrl-K as explained in [Wayback/Archive] Changing default page view in Adobe Acrobat

When you open a PDF in Adobe Acrobat Reader, the default page view may not be to your liking. For example, it may show a full page when you really need to see part of a page in full width.

To change these settings follow the steps below.

  1. Edit, Preferences (or Control-K).
  2. Choose Page Display in the Categories section.
  3. In the Default Layout and Zoom section (top of page), change the Page Layout and Zoom selections to your preference. “100%” and “Fit Page” are most commonly used in the Zoom selection.
  4. Click OK to save your settings.

Contrary to the above, the defaults for both my Acrobat Reader both the “Paye Layout” and “Zoom” settings were “Automatic”. I just changed the “Page Layout” to “Two-Up” and am much happier now (:
