Question details
The user wants to add numbered balloon callouts (boxes with arrows and numbers) to annotate PDF drawings.

- Product
- Adobe Acrobat XI Pro
- Device & OS
- not provided
- Scenario
- Annotating and marking up PDF technical drawings or documents with sequential numbered callouts.
- Observed behavior
- The user needs to manually create balloon-style callouts with text and arrows to point out specific parts of a drawing, as the software does not auto-generate sequenced balloons.
Ensure your PDF document allows for comments and annotations. If the PDF is secured or restricted, you will need to enter the permissions password to unlock it before adding callouts.
Use the Text Callout Commenting Tool
Utilize the built-in text callout feature to draw a text box with an attached arrow pointing to specific details on your drawing.
The Text Callout tool creates a combined text box and arrow that points precisely to a location on your PDF. You can customize the border, shape, and fill color, then manually type your sequence numbers inside the box.
Open your PDF and navigate to the Comment or Annotations pane. Select the 'Text Callout' tool from the drawing markups menu.
Click once on the specific part of the drawing you want the arrow to point to, then drag and click again where you want the text box (balloon) to appear.
Click inside the newly created text box and type the desired number (e.g., '1').
Right-click the callout box, select 'Properties', and adjust the shape, border color, and text size to resemble a standard numbered balloon. You can then copy and paste this callout for subsequent numbers to maintain consistent formatting.

Frequently Asked Questions
Can I make the callout numbers auto-increment automatically?
In standard PDF commenting tools, callout numbers do not auto-increment. You must manually type the sequential numbers inside each text box as you create or paste them.
How do I change the color of the callout arrow and box?
Right-click the callout annotation, select 'Properties', and navigate to the Appearance tab. From there, you can change the border color, fill color, and line thickness of both the box and the arrow.
Why can't I select the Text Callout tool in my PDF?
This usually happens if the PDF is protected against editing or commenting. Check the document security properties to ensure commenting is allowed, or ask the document author for the password to unlock these features.
How do I move the text box without moving the arrow point?
Click on the callout box to select it. Click and drag the box itself to reposition it; the arrowhead will remain anchored to the original spot on the drawing.
