How to Change the Appearance and Size of Revision Clouds in Adobe Acrobat
Question details
The user wants to enlarge the individual arcs of revision cloud annotations rather than just increasing the line thickness.

- Product
- Adobe Acrobat Pro
- Device & OS
- not provided
- Scenario
- Annotating and reviewing PDF documents with revision clouds.
- Observed behavior
- The revision clouds appear as small box-like arches, and the user cannot find a dedicated setting to increase the size of the individual arcs independently of the overall shape.
Ensure your PDF document is not restricted from commenting and that you have the Comment toolbar enabled to access shape properties.
Adjusting Cloud Properties and Resizing the Annotation
Use the Properties panel and drag the bounding box handles to resize the annotation and adjust its appearance.
Adobe Acrobat allows you to change the color, opacity, and line thickness of revision clouds. However, Acrobat does not currently offer a built-in control to manually adjust the specific radius or size of the individual arcs (the "bumps") that make up the cloud.
Click on the existing revision cloud annotation in your PDF document to select it. You will see a bounding box appear around the shape.
Right-click the selected cloud and select 'Properties' from the context menu. Here you can change the color, line style, opacity, and thickness.
To make the cloud and its arcs larger, click and hold any of the corner or edge handles on the bounding box, then drag outward to expand the entire shape.

Frequently Asked Questions
Why do my revision clouds look like small boxes in Acrobat?
This typically happens if the overall size of the drawn cloud is very small or if the line thickness is set too high relative to the cloud's dimensions. Dragging the corner handles to enlarge the overall cloud often resolves the boxy appearance.
Can I change the default color of revision clouds in Adobe Acrobat?
Yes. Right-click an existing revision cloud, choose 'Properties', pick your desired color and style, and check the 'Make Properties Default' box at the bottom of the dialog window before clicking OK.
Is it possible to change the radius of the arcs in a PDF revision cloud?
Adobe Acrobat does not provide a specific setting to manually adjust the arc radius. The size of the individual arcs scales automatically when you resize the entire annotation bounding box.
