Go Big in Size and Style With 9” x 12” Envelope Printing

When a small bland white envelope just won’t do, go with 9” x 12” envelope printing. These custom envelopes are perfect for letter-sized documents that cannot be folded when mailed such as booklets, catalogs, contracts, folders, and reports, among others. Custom 9” x 12” envelopes add a more professional look to your mail and help attract more attention to it.

What else can fit in a 9” x 12” envelope?

  • Any 8.5” x 11" flat card
  • 11” x 17" cards, brochures, flyers, or menus that are folded to an 8.5” x 11" size
  • 8.5” x 11” booklets, catalogs or wall calendars

All 9” x 12” envelopes feature a gummed flap for an easy permanent seal. So, all you need to do is decide what you want to put on your envelopes. With NextDayFlyers’ premium custom 9” x 12” envelopes, mailing bulky documents need not be an intimidating and awkward affair.

Will printing turnaround also include the time needed to ship my order?
No. The printing turnaround time shown on the online calculator only means the number of days to produce your order. To know the estimated transit time and expected arrival of your order, click on the “Get Delivery Estimate” button at the bottom of the calculator.

How do I print a custom envelope?
If your design is print-ready, you can upload a file directly on our website. Select “Upload Your File” and then submit your PUB, TIF, PDF, DOC, JPG, or PNG file for us to print. You can choose to review a free PDF proof online before we proceed to production.

What are the standard sizes of envelopes?
Apart from the 9” x 12", the other standard sizes are at 6”x 9" and 8.75” x 11.5”.

What is the difference between 1-color and full-color printing?
1-color printing means your design will only be printed in one ink color, and you can choose from black, reflex blue, or standard red ink color options. This print option is a non-bleed print, so printing cannot go to the edge of the envelope. Standard 24 lb. white paper is used for the envelope.

Full-color printing allows you to have your design printed on the front and back of the envelope. A thick, heavyweight 70 lb. opaque white envelope paper is used for this printing option.

What is “free proof”?
This is a free service that NextDayFlyers offer to all customers. Your selected design is checked by our talented prepress team before it is printed. If you are in a rush or have specific printing concerns, this service is recommended for you.
