How to Increase Acrobat Liquid Mode Text Size on iPad
Question details
The user needs a way to increase the text size in Adobe Acrobat Liquid Mode when the app's internal adjustments fail, as well as a better alternative to the iPad's Smart Invert for reading.

- Product
- Adobe Acrobat Reader
- Device & OS
- iPadOS
- Scenario
- Reading PDF documents in Liquid Mode on an iPad, particularly for users with visual impairments who require larger fonts and dark backgrounds.
- Observed behavior
- Text size adjustments within Acrobat Liquid Mode do not respond for certain PDF files, and the system Smart Invert feature provides a suboptimal reading display.
Ensure your iPad is updated to the latest version of iPadOS and verify that the 'Text Size' control is added to your Control Center settings.
Use iPad Accessibility Settings to Force Text Size
Override Acrobat's internal settings by using the iPad's system-wide text size feature specifically targeted for the Acrobat app.
When Acrobat's Liquid Mode fails to adjust the text size internally, iPadOS allows you to force an application-specific text size override from the Control Center.
Open your iPad 'Settings', navigate to 'Control Center', and tap the green plus icon next to 'Text Size' to enable the shortcut.
Swipe down from the upper-right corner of your iPad screen to reveal the Control Center panel.
Long-press the 'Aa' icon, toggle the setting at the bottom from 'All Apps' to 'Acrobat Only', and drag the slider upwards to increase the text to a comfortable reading size.

Use Acrobat Night Mode Instead of Smart Invert
Switching to Acrobat's built-in Night Mode provides a better dark reading experience than the iPad's Smart Invert, which can distort images.
Use WPS Office Mobile View for Smooth PDF Reading
If Acrobat's Liquid Mode is unresponsive, WPS Office provides an excellent Mobile View feature. It automatically reflows PDF text to perfectly fit your iPad screen, letting you adjust font sizes freely and switch to an eye-friendly Dark Mode.
- 1. Install WPS Office: Download WPS Office for free from the App Store and open your PDF document.
- 2. Activate Mobile View: Tap the 'Mobile View' icon located on the bottom toolbar to automatically reflow the document's text.
- 3. Adjust Font Size: Use the on-screen text adjustment tools provided in Mobile View to increase the font size without relying on system accessibility settings.
- 4. Enable Dark Mode: Access the view settings within the app to toggle Dark Mode on for a comfortable, high-contrast reading environment.

Frequently Asked Questions
Why won't Liquid Mode text size adjust in some PDFs?
Certain complex or heavily formatted PDF files restrict Acrobat's Liquid Mode from fully parsing and reflowing text, which disables the internal font size adjustments. Using the iPad's system-wide text size override is the best workaround.
How do I add the text size icon to my iPad Control Center?
Open your iPad Settings, navigate to 'Control Center', and tap the green plus sign next to 'Text Size'. This action adds the 'Aa' icon to your quick settings menu.
What is the benefit of Night Mode over Smart Invert?
Smart Invert is a system feature that forces all screen colors to reverse, which can heavily distort images and graphics in your PDF. Acrobat's built-in Night Mode applies a dark background to the text area while intelligently preserving the true colors of images.
