Fix Word Size Menu Missing or Freezing for Envelope Sizes
Question details
The user is unable to select envelope sizes in Microsoft Word because the Page Layout Size menu is either missing or causes the application to freeze.

- Product
- Microsoft Word
- Device & OS
- Windows
- Scenario
- Attempting to change the document paper size to an envelope format using the Page Layout tab.
- Observed behavior
- Microsoft Word stops responding (freezes) or fails to display the Size menu dropdown, preventing the user from formatting the document for envelope printing.
Make sure to save any open documents and ensure your Windows operating system and printer drivers are fully up to date before proceeding.
Run Word in Safe Mode and Disable Problematic Add-ins
Starting Word in Safe Mode bypasses third-party add-ins. If the menu works in Safe Mode, a disabled add-in is likely the culprit.
Many freezing issues in Microsoft Office are caused by outdated or incompatible third-party add-ins that interfere with the application's interface.
Press Windows + R on your keyboard to open the Run dialog box. Type 'winword /safe' and press Enter to open Word in Safe Mode.
Navigate to the Page Layout tab and click on Size. If the envelope sizes appear and the app does not freeze, proceed to the next step.
Click on File in the top left corner, then select Options. In the Word Options window, click on Add-ins on the left sidebar.
At the bottom of the window, ensure 'COM Add-ins' is selected in the Manage dropdown and click Go. Uncheck all add-ins in the list and click OK. Restart Word normally to see if the issue is resolved.

Change the Default Printer Temporarily
Word communicates with your default printer to load available paper and envelope sizes. A corrupted printer driver can cause the menu to freeze.
Repair the Microsoft Office Installation
Use the built-in Windows repair tool to fix corrupted Office program files that might be causing the Size menu to disappear.

Frequently Asked Questions
Why does the page layout size menu cause Word to freeze?
Word dynamically queries your default printer's driver to populate the available paper and envelope sizes in the Size menu. If the printer driver is outdated, corrupted, or unresponsive, Word will hang while waiting for the data.
How do I print envelopes without using the Size menu?
Instead of manually changing the page layout size, you can go to the Mailings tab in Word and click on Envelopes. This opens a dedicated dialog box where you can type delivery and return addresses and select the envelope size directly via Options.
Will updating my printer driver fix the missing Size menu?
Yes, in many cases, downloading the latest driver from your printer manufacturer's official website and installing it will restore communication between Word and the printer, fixing the missing menu and freezing issues.
