- Scenario
- Formatting a business letter or multi-page document for mailing in a window envelope.
- Observed behavior
- The recipient address must be properly placed on the first or second page and folded correctly to align precisely with the envelope window.
Measure the exact dimensions of your window envelope using a ruler, specifically noting the distance from the top and left edges of the envelope down to the transparent window.
Adjust Address Layout and Use a Z-Fold
Position the inside address at the top of the letter and fold the paper using an accordion style so the address remains visible on the outside.
A standard C-fold folds the top of the letter inward, which hides the address. By using a Z-fold, the top section of the page is kept on the outside face, allowing the printed address to show perfectly through the window.
Open your document and adjust the top and left margins, or insert a text box, to match the exact measurements of your envelope's window.
Enter the recipient's address into the designated area at the top of your business letter.
Go to the Print menu (Ctrl + P) and print your document normally on standard paper.
Fold the paper in an accordion style (Z-fold) rather than a standard C-fold, ensuring the address block remains on the outer face. Insert it into the envelope to verify alignment.

Position Address on the Second Page (Duplex Printing)
For two-page documents, format the address on the reverse side of the paper by printing in duplex mode.

Frequently Asked Questions
What is the difference between a Z-fold and a C-fold for window envelopes?
A Z-fold folds the paper back on itself like an accordion, keeping the top address block on the outside. A C-fold folds the top and bottom inward, which often hides the top address inside the fold.
How do I find the exact measurements for my window envelope?
Use a physical ruler to measure the distance from the top edge and left edge of the envelope to the transparent window. Use these measurements to set the exact top and left margins or text box position in your word processor.
Can I use the mail merge feature for window envelopes?
Yes. You can position a text box or frame on your main document template to match the window layout, then insert your mail merge address fields directly into that designated box before completing the merge.
