6x9 Envelopes
Custom 6x9 Envelopes for Booklets & Half-Sheets
Stop folding your documents three times. The 6x9 envelope is the perfect mid-size solution, specifically designed to fit 5.5" x 8.5" inserts flat and secure.
Whether you are mailing a multi-page marketing booklet, an oversized greeting card, or a standard letter folded just once, our 6x9 envelopes provide a snug, professional fit. Our envelopes prevent your materials from shifting in transit and ensure your brand arrives in pristine condition.
What Fits Inside a 6x9 Envelope?
The 6x9 is often called the 'Half-Sheet' envelope because it fits a standard 8.5" x 11" sheet of paper folded exactly in half. This makes it a versatile choice for businesses looking to upgrade from standard #10 envelopes.
-
5.5x8.5 Booklets & Catalogs: The ideal outer envelope for mini-catalogs or event programs.
-
Half-Folded Invoices: Give your billing statements a premium feel with a single fold instead of a tri-fold.
-
Oversized Cards: Perfect for 5x7 or 6x8 greeting cards, invitations, and 'Save the Date' mailers.
-
Marketing Kits: Roomy enough for multi-piece inserts without bending corners.
Choosing the Right Style: Booklet vs. Catalog
Not all 6x9 envelopes open the same way. Choosing the right flap style is critical for your workflow:
-
6x9 Booklet Envelopes (Open Side): The flap is on the long (9-inch) dimension. This is the best choice for automatic insertion machines and makes it easy to insert bulky booklets by hand.
-
6x9 Catalog Envelopes (Open End): The flap is on the short (6-inch) dimension. This classic 'policy' style offers extra security for heavy documents and prevents contents from falling out when opened.
