Here is a template for Word that will put the addresses in the right place when printed and placed in a #10 window envelope. Here’s how to use it:
- Enter your return address and the recipient’s address in the boxes at the top of the page. Be sure to keep the address within the boxes.
- Write your letter and print it.
- Fold the letter along the line on the right side of the first page. This will make sure that the folded letter is large enough so it doesn’t slide around in the envelope and move the addresses out of the windows.

Update: Letter_No10_Envelope.dot – Word 97-2003 version

I know this is for Word 2007. Is there a way to convert it to Word 2000?
Hi Ted, you should be able to use these instructions to open most Word 2007 documents in older versions of word: Open a Word 2007 document in an earlier version of Word
Just in case, here’s the template converted to Word 97-2003: Letter_No10_Envelope.dot
Thanks a lot. Works perfectly.
