- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Creating new documents after printing envelopes or modifying custom paper settings.
- Observed behavior
- New documents are defaulting to incorrect paper sizes, such as a #10 envelope, instead of the standard US Letter size.

Reset the Default Paper Size in Page Setup
Change the paper size in the Layout tab and apply it to the Normal template so all future documents automatically use US Letter.
By modifying the settings in the Page Setup dialog, you can override the incorrect paper size that was inadvertently saved to your global template.
Open a new or existing document, navigate to the Layout tab on the ribbon, click on Size, and select More Paper Sizes at the bottom of the drop-down menu.
In the Page Setup dialog box under the Paper tab, choose US Letter (8.5 x 11 inches) from the Paper size drop-down menu.
Click the Set As Default button located at the bottom left corner of the dialog box.
A prompt will ask if you want to apply this change to all new documents based on the NORMAL template. Click Yes to confirm and save your settings.

Frequently Asked Questions
Why did my default paper size change to an envelope?
When you create or print an envelope, the word processor sometimes temporarily overrides the default paper settings for the active session or inadvertently saves the envelope format to the default document template.
What is the Normal template?
The Normal template (Normal.dotm) is the default global template used by your word processor. It dictates the base formatting, including margins, fonts, and paper size, for any new blank document you create.
How do I change the default margins along with the paper size?
You can change default margins in the same Page Setup dialog box. Go to the Margins tab, enter your desired measurements, and click the 'Set As Default' button just as you did for the paper size.
Will changing the default paper size affect my previously saved documents?
No, altering the default paper size only applies to new documents created from the Normal template moving forward. Existing documents will retain the specific paper sizes they were originally saved with.
