Enable Reading Mode in Adobe Acrobat Reader Mobile
Use the built-in Reading Mode to automatically adjust and wrap the PDF text to match the width of your mobile screen.
Adobe Acrobat Reader provides a dedicated Reading Mode (often updated to Liquid Mode in newer versions) that optimizes standard PDF text for smaller displays, eliminating the need to scroll left and right.
Launch the Adobe Acrobat Reader mobile app and open the PDF file you wish to read.
Tap anywhere on the document screen to reveal the toolbars, then select the first icon located at the bottom left corner to open the viewing options menu.
Choose 'Reading Mode' from the menu. The app will instantly reformat the text to fit the width of your screen with small margins.
If the desired fit-to-width display is unavailable or formatting breaks, you can submit a request through the Adobe Feature Request or Bug Report Form online.

Use WPS Office Mobile View to Fit PDF Text to Screen
WPS Office features an advanced 'Mobile View' designed specifically for smartphones. It intelligently extracts the text from your PDF and reflows it to fit your screen perfectly, offering a seamless reading experience without the need to zoom or scroll horizontally.

- 2. Open your PDF: Launch the app and open your PDF document from your device storage or cloud drive.
- 3. Activate Mobile View: Tap the 'Mobile View' icon located at the bottom menu. The PDF text will immediately reflow to fit your screen.
- 4. Customize reading settings: Use the on-screen options to increase or decrease the font size for maximum reading comfort.

Frequently Asked Questions
Why does my PDF not fit the screen properly in Reading Mode?
Some PDFs, especially image-based scanned documents or files with highly complex formatting, may not reflow correctly. Reading Mode relies on readable text layers to dynamically adjust the layout.
Is Liquid Mode the same as Reading Mode in Adobe Acrobat?
Yes, Liquid Mode is an evolution of the traditional Reading Mode in the Adobe mobile app. It uses artificial intelligence to identify parts of a PDF and dynamically reflows text, images, and tables for optimal mobile viewing.
Can I use 'Fit to Width' on the desktop version of a PDF reader?
Yes. On most desktop PDF readers, including Adobe Acrobat and WPS Office, you can select 'View' > 'Zoom' > 'Fit Width' (or use shortcuts like Ctrl+2) to automatically scale the document so its width matches your application window.
