In the right pane field list, click on one text field, then press Ctrl+A on Windows or Command+A on Mac to select all fields. Alternatively, hold the Ctrl or Command key and click specific text fields to exclude non-text fields manually.

Frequently Asked Questions

Why can't I change the font size for all fields at once?

This usually happens if you select a mix of different field types, such as text boxes alongside checkboxes or radio buttons. Font size properties only apply to text-based fields. Ensure you select only text fields using the Ctrl or Command key.

Can I set a default font size for all new PDF form fields?

Yes, in most advanced PDF editors, you can right-click a text field with your preferred font size and select 'Use Current Properties as New Defaults'. Any new text fields you create will automatically use this font size.

Does changing the font size affect the existing text in the fields?

Yes, modifying the field's appearance properties will automatically update the font size of any text that has already been typed into those specific form fields.

What does 'Auto' font size mean in PDF forms?

Setting the font size to 'Auto' allows the text to automatically shrink or expand to fit within the boundaries of the text field as the user types.
