Question

Adobe window keeps enlarging when opening PDF

I’ve had an issue with Adobe Acrobat where I open a PDF and the application window doubles in size. I close the PDF, open another PDF and its even larger. Eventually after a couple opens, the acrobat application window is full screen, although not “Fullscreen” its fully maximized to where I need to grab the corner with my mouse and manually resize to a typical document window size. This is happening from a closed instance to opening a PDF. If I only close the document (tab) and leave acrobat running, its fine.

This is happening on my Windows 11 Business edition (Surface Pro 11). I have since recently restored/factory reset my Surface with a fresh reinstall of Windows 11 Pro/Business. Fresh installed Adobe Acrobat and the symptom is still happening. It was happening before and after a fresh windows install. I have the latest version at 64bit 25.001.21184.

I have AI searched for a solution and they didnt help resolve it. Anyone have any ideas or having the same problem?

      I have this same problem and discovered today it is not document dependent (I have tried all the suggestions...no joy).  Each time I invoke Adobe (not opening a file) the program window gets progressively larger until it fills the screen.  Here’s the rub - I have dual screens (15” laptop and 32” monitor), and the behavior only happens if Adobe is opened/closed/opened on the large monitor.  My current work around is to open a pdf (or Adobe), on my laptop screen, move it to my large monitor to work on the pdf, then move the program window back to my laptop screen before exiting.  My screen settings are thus (using Windows 11, 23H2):

      Laptop screen = 100% scale; 1920 x 1080 resolution (recommend)

      32” monitor = 150% scale (recommended); 3840 x 2160 resolution (recommended)

      Perhaps matching either the scales or resolution (or both) may fix the ever-expanding Adobe window?  I have not tried this.

       

      This growing window behavior does not occur if I change my default pdf program to a browser (e.g. Edge, Chrome).  I do not want to do this...I much prefer Adobe.

      Hope this makes sense and helps.

      Note:  This issue seems to have started in the last year or so...certainly no more than 2 years.

      ​@jasqid GJS001_ Maybe, this will help. In acrobat, in the preferences, you can set it up it will open the last settings open. So, if you last document was viewed ay 200% viewing, when you open the next PDF it will open in 200%. I have my setting turned off in Documents - Open Settings 

       

      Now, in your settings, I would go into Page Display - Default Layout and Zoom and change the Page Layout and Zoom to be Automatic. Once done, click OK, and restart Acrobat. When you open Acrobat, it should open to Fit Width (unless, the person creating the PDF said otherwise, as they can also set the viewing properties as well!)

        Hello ​@jasqid 

         

        I hope you are doing well, and thank you for reaching out. We’re sorry for the trouble you had.

        When Acrobat launches from a closed state, it reapplies Page Display + DPI scaling + document Initial View, causing the window to grow each time. Leaving Acrobat open avoids the reset, which matches your observation.

         

        Reset Page Display & resolution (most effective)

        • Acrobat > Menu > Preferences > Page Display
        • Set Default Layout to Single Page
        • Set Default Zoom to Fit Page
        • Set Resolution to Use System Setting (120 PPI)
        • Restart Acrobat

        Check the screen scaling setting

        • Acrobat > Menu > Preferences > General
        • Scale for screen resolution > Auto‑Detect
        • Restart Acrobat
        • Some PDFs are saved to resize the window or open at a specific magnification
        • Check Menu > Properties > Initial View on affected PDFs

         

        You can also refer to this Adobe article: Viewing PDFs and viewing preferences.

        I hope this helps.

        Regards,

        Anand Sri.

        Unfortunately, I made adjustments to match your (Most Effective) preferences edits and the issue still persists. I even tried adjusting to Custom Resolution 120PPI and there was no difference.
