- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Adding comments or sticky notes to a PDF document.
- Observed behavior
- The visual indicators for comments or sticky notes render at a much larger size than intended.
Verify your current system display resolution and check if the issue is isolated to a specific PDF document or happens across all files.
Update Adobe Acrobat and Verify Document Settings
Ensure you have the latest software patches installed and check if the issue is tied to a specific document's page size.
Often, application bugs regarding annotation scaling are patched in recent updates. Additionally, if a document was created with unusually small page dimensions, standard-sized comment indicators will appear disproportionately massive.
Open Adobe Acrobat, navigate to the 'Help' menu at the top, and click on 'Check for Updates'. Install any available patches and restart the application.
Open a completely different PDF file containing standard text to see if the comment indicators render correctly in that file.
Press 'Ctrl + D' (or go to File > Properties) to open the Document Properties. Under the 'Description' tab, check the 'Page Size' to ensure it is not abnormally small.
Adjust System and Application Display Scaling
Fix indicator size issues by overriding high DPI scaling behavior that may improperly enlarge interface elements.
Use WPS PDF for Flawless Document Annotation
Avoid scaling and display glitches by using WPS Office's built-in PDF editor. It offers a lightweight, smooth experience for adding sticky notes, highlighting text, and collaborating on PDF documents without compatibility or rendering issues.
- 1. Open your document in WPS: Download and launch WPS Office, then open your problematic PDF document.
- 2. Navigate to the Comment tab: Look at the top ribbon menu and click on the 'Comment' tab to access all annotation features.
- 3. Select the Note tool: Click on the 'Note' icon (or your preferred markup tool) from the available options.
- 4. Place your comment: Click anywhere on your document to place a perfectly sized comment indicator and type your feedback.

Frequently Asked Questions
Why do PDF comments look huge in some documents but normal in others?
This usually happens because the underlying page size of a specific document is exceptionally small. The application renders the sticky note at a fixed standard dimension, making it appear disproportionately large relative to a tiny page.
Can I manually change the default sticky note icon size in Acrobat?
While you can adjust the font size inside the note pop-up via Edit > Preferences > Commenting, the physical sticky note icon placed on the page usually scales automatically and cannot be manually resized.
Does high display scaling affect PDF comment indicators?
Yes, if your system display scaling is set higher than 100% (e.g., on a 4K monitor) and the application fails to scale its interface correctly, elements like comment indicators may render much larger than intended.
