Fix Linked Excel Charts That Resize in PowerPoint
Question details
Users are experiencing an issue where Excel charts linked within PowerPoint presentations automatically change size or distort when the file is reopened and the links are updated.
- Product
- Microsoft PowerPoint / Microsoft Excel
- Device & OS
- not provided
- Scenario
- Reopening a presentation containing linked data and updating the workbook links.
- Observed behavior
- The linked Excel charts resize unexpectedly, affecting the layout of multiple presentations and impacting various users within an organization.
Ensure that both your Microsoft Excel and PowerPoint applications are updated to their latest versions, as Microsoft occasionally releases patches for known object linking bugs.
Submit Feedback and Open a Support Ticket
Since this is a known rendering bug within the Microsoft Office ecosystem, reporting it directly to Microsoft is the primary path to a permanent resolution.
Because multiple users have experienced similar issues with different files, this indicates a software-level bug rather than user error. Microsoft relies on user logs to investigate and deploy fixes for linked-chart behaviors.
Open the PowerPoint application where the resizing issue occurs. Navigate to the Help tab on the top ribbon and select Feedback to detail the issue.
If you are using a work or school account, reach out to your Microsoft 365 administrator and ask them to raise a support ticket so Microsoft can collect logs and investigate.
Workaround: Embed the Chart or Paste as Picture
If you need an immediate fix for an upcoming presentation and cannot wait for a software patch, you can break the external link and embed the chart instead.

Frequently Asked Questions
Why do my Excel charts resize when I update links in PowerPoint?
This is a known compatibility and rendering issue in some versions of Microsoft Office. When PowerPoint requests updated data from the linked Excel file, it sometimes recalculates the chart area boundaries or defaults to the source file's original resolution, causing it to resize or distort on the slide.
Can I prevent charts from resizing without breaking the link completely?
While a permanent fix relies on Microsoft patches, locking the aspect ratio in the chart's formatting properties within PowerPoint, or ensuring the source Excel file is open before you open the PowerPoint file, can sometimes mitigate the unexpected resizing.
Does the chart resize issue happen if I use WPS Office?
WPS Office utilizes an optimized object embedding engine that maintains high fidelity with your original chart sizes and formatting. This greatly reduces the occurrence of unexpected resizing when updating presentation data from spreadsheets.
