Modify Text Field Properties in Adobe Acrobat Pro
Adjust the appearance settings for individual or multiple text fields directly within the Prepare Form tool.
In Adobe Acrobat, the font size and color for fillable fields are controlled by the specific properties of each form field, rather than by the general preferences of the overall PDF document. You must edit these properties directly in the form editing mode.
Launch your PDF form in Adobe Acrobat Pro, navigate to the 'Tools' menu at the top, and select 'Prepare Form'.
Right-click on the relevant text field that you want to customize and select 'Properties' from the drop-down context menu.
In the Properties dialog box, click on the 'Appearance' tab. Here, you can select your preferred font family, choose a specific font size, and pick a text color (such as red or blue).
Close the properties dialog to apply the new settings. Save your document and test the fillable fields in Adobe Acrobat Reader to ensure the text appears with your selected formatting.

Frequently Asked Questions
Why does the font size shrink when users fill out my PDF form?
If the font size is set to 'Auto' in the text field properties, the text will dynamically shrink to fit inside the box as the user types more characters. To maintain a consistent size, uncheck 'Auto' and manually select a fixed font size (e.g., 12pt) in the Appearance tab.
Can I set a global default font for all new PDF form fields I create?
Font settings are typically applied on a per-field basis rather than through a global application setting. The best workaround is to create one template text field with your desired properties, then duplicate or copy-paste it throughout your document to maintain consistency.
How do I change the font color of regular text in a PDF, not just fillable form fields?
To change the color and size of static document text rather than interactive form fields, you need to use the 'Edit Text' or 'Edit PDF' tool. This allows you to highlight the existing text on the page and modify its formatting using the text editing panel.
