How to Adjust Line Spacing When Editing PDF Text on Mac
Question details
The user needs to adjust the line spacing of existing text within a PDF document on a Mac but cannot find the proper formatting options.
- Product
- Adobe Acrobat
- Device & OS
- Mac
- Scenario
- Formatting existing paragraphs and preventing text from shifting unpredictably after inserting new characters.
- Observed behavior
- Line spacing controls and text formatting options appear missing in the Properties bar, often because the text is being interacted with as a comment rather than editable content.
Ensure you are using a comprehensive PDF editor rather than a basic PDF reader, as reading applications only allow basic markup and lack advanced text formatting capabilities.
Use the Edit PDF Tool Instead of the Comment Tool
Switch from the commenting tools to the dedicated PDF editing tools to access paragraph formatting and line spacing controls.
A common mistake when modifying PDFs is using the 'Add Text Comment' tool instead of actually editing the document's base text. Comments have limited formatting options, which is why line spacing controls may disappear from the Properties bar. Using the actual Edit tool ensures the text reflows correctly without shifting when you insert new characters.
Open your PDF file in Acrobat. Navigate to the right-hand pane and click on the 'Edit PDF' tool, rather than selecting any options under the 'Comment' section.
Click directly on the text or the bounding text box you wish to modify. This will activate the text selection.
Look at the format panel on the right side of the screen. With the text box properly selected, the text formatting and line-spacing controls will now be visible.
Locate the line spacing numeric field in the Properties bar and increase or decrease the value to achieve your desired paragraph spacing.

Frequently Asked Questions
Why does my PDF text shift randomly when I add new characters?
Text shifting usually happens when you insert text using the Comment tool over existing text, or if the PDF's internal bounding boxes are misaligned. Using a dedicated 'Edit PDF' tool ensures the text reflows correctly within its defined line spacing and margins.
Can I adjust line spacing for PDF sticky notes or comments?
Standard PDF comments and sticky notes generally have very limited formatting options and do not support advanced paragraph spacing. To fully control line spacing, the text must be added as actual PDF document content using an Edit tool.
Is there a way to change the default line spacing for all text in a PDF?
PDFs do not operate with global styles like Word documents. There is no single setting to change default line spacing across an entire existing PDF; you must select individual text boxes with the Edit PDF tool and adjust their spacing manually in the format panel.
