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.

1
Add Text Size to Control Center

Open your iPad 'Settings', navigate to 'Control Center', and tap the green plus icon next to 'Text Size' to enable the shortcut.

2
Open Control Center

Swipe down from the upper-right corner of your iPad screen to reveal the Control Center panel.

3
Adjust App-Specific Font Size

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.

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.
