Device & OS

Scenario
Filling out or designing a PDF claim form where the entered text exceeds the fixed field size.
Observed behavior
When too much text is entered, a plus sign appears indicating overset text, and the text does not scale down to fit the allotted field space.
Before you start

Determine whether you only have permission to fill out the form, or if you have authoring rights to edit the PDF form's underlying field properties.

Solution 1Recommended

Change Field Font Size to Auto (For Form Designers)

If you created the form or have editing permissions, you can adjust the field properties to automatically scale text to fit the box.

This is the most effective solution, as it allows users to type as much as they need while keeping the document layout intact for faxing and printing.

1
Open the PDF in Editing Mode

Open the PDF document in your PDF editor or Adobe Acrobat, and launch the 'Prepare Form' or 'Form Edit' tool.

2
Access Field Properties

Right-click on the specific text field that is overflowing and select 'Properties' from the context menu.

3
Set Font Size to Auto

Navigate to the 'Appearance' tab in the Properties window. Find the 'Font Size' dropdown menu and change it to 'Auto'.

4
Save the Changes

Close the properties dialog box and save your PDF document. Any text entered into this field will now shrink automatically to fit the visible area.

Change Field Font Size to Auto (For Form Designers)
Auto-scaling applied: Once set to Auto, the text will seamlessly resize itself based on the amount of content, permanently eliminating the overflow plus sign.

Frequently Asked Questions

Why does a plus sign appear when I type in a PDF form?

The plus sign indicates that the text you have entered exceeds the physical boundaries of the text field. It serves as a warning that some text will be hidden when printing or viewing outside of edit mode.

Can I force a locked PDF form to resize my text?

No, if the form creator locked the document or restricted editing, you cannot change the field properties. You must either abbreviate your text or contact the author for an updated version.

Will the plus sign print if I leave it there?

In most PDF readers, the plus sign itself may not print, but the text that overflows the box will be cut off, resulting in incomplete information on your printed or faxed document.
