How to Fix Excel 365 Displaying Incorrect Rectangle Size Values
Question details
Users experience a discrepancy between the entered shape dimensions and the actual values displayed in Excel 365.

- Product
- Microsoft Excel 365
- Device & OS
- Windows
- Scenario
- Formatting and resizing shapes or rectangles in an Excel worksheet.
- Observed behavior
- The displayed height, width, Scale Height, or Scale Width values of rectangles differ from the exact values entered in the Format Shape pane, which is often noticeably worse on large shapes or displays.
Ensure your Excel workbook is saved and closed before attempting to launch the application in Safe Mode.
Launch Excel in Safe Mode and Disable Conflicting Add-ins
Starting Excel in Safe Mode allows you to bypass third-party add-ins and extensions that may be causing the visual bug.
Display inconsistencies, such as incorrect shape scaling or dimension rendering, are frequently caused by incompatible COM add-ins interfering with Excel's rendering engine. Safe Mode isolates the application from these extensions to help you identify the culprit.
Press the Windows key + R simultaneously on your keyboard to open the Run command window.
Type 'excel /safe' into the text box and press Enter or click OK. Excel will now open in Safe Mode.
Open your workbook or create a new one. Draw a rectangle and check if the Format Shape dimensions now accurately match the displayed values.
If the issue is resolved in Safe Mode, go to File > Options > Add-ins. Select COM Add-ins from the Manage drop-down and click Go. Uncheck all add-ins to disable them, then re-enable them one at a time to pinpoint the add-in causing the incorrect display values.

Frequently Asked Questions
Why do shapes change size when viewing Excel on different monitors?
Different monitors often have varying DPI scaling settings. Excel attempts to scale the UI and canvas based on your primary display, which can sometimes distort shape rendering. Adjusting your Windows display scaling to match across monitors can help mitigate this.
How do I lock a rectangle's size and position in Excel?
Right-click the rectangle, select 'Size and Properties', navigate to the 'Properties' section, and choose 'Don't move or size with cells'. This prevents the shape from altering its dimensions when underlying rows or columns are modified.
What exactly does Excel Safe Mode do?
Safe Mode starts Excel in a clean state, bypassing default startup locations, customized toolbars, and third-party add-ins. This makes it an essential diagnostic tool for identifying software conflicts or display bugs caused by external plugins.
Can zooming affect shape dimensions in my worksheet?
Yes, zooming in and out can cause minor visual discrepancies on-screen due to pixel rendering limitations on your monitor, although the actual printed dimensions of the shape remain perfectly unchanged.
