50 FREE Envelope Templates in Every Size (PDF – Word)

An envelope is a packaging item, often made of thin flat material. Envelopes are designed to contain flat objects, such as a card or a letter. Customarily, envelopes are made from sheets of paper cut into one of three shapes; short arm-cross, kite, or a rhombus. These shapes allow for the creation of the envelope structure by folding the sheet sides around a central rectangular area. In this manner, a rectangular-faced enclosure is formed with four flaps on the reverse side.

Envelopes are commonly used for sending cards, documents and letters using regular postal mail; however, they can also be used for other purposes such as:

  • Storing extra receipts
  • Storing allowance for each family member
  • Storing and organizing stamps and return address labels
  • making announcements
  • Storing promotional pieces
  • Sending invitations
  • Etc.

                Generating an Envelope Template

                Here is a step by step guide for you to generate a perfect envelope of your choice :

                Step 1

                To generate an envelope template, you have to open a new word document or start from the document that you want to add an envelope. Then select the “mailings” tab.

                Step 2

                Click on “Envelopes” in the Create group to open the envelopes and labels dialog box. Then click on the “Options” button to open the Envelope Options dialog box.

                Step 3

                Next, click the arrow in the Envelope Size Box dialog and select the template size for the envelope that you want to print. Click on “Customize Size” and manually enter the envelope dimensions if the envelope size you want is not included in the templates provided.

                Step 4

                In the Delivery Address or Return Address section, click the “Font” button

                Now, choose a custom font type, style, and color for either or both addresses, then click “OK” when done.

                Step 5

                If you wish to use the template you have created again, add it to the document by clicking on “Add to Document.” This can be beneficial for form letters, official letters and other related documents.

                Step 6

                The final step when generating an envelope template is to follow your printers’ instructions and insert a blank envelope into the printer. Then click on the “Print” button when ready to print. It is important that you add the document to the document if you are planning to use it again, as it will disappear after printing.

                Formatting Double Window Envelope

                Most small businesses normally use double-window envelopes to save on printing costs. Setting up a double-window envelope is not hard and should only take a few minutes. Here is how to format a double window envelope:

                • Step 1: Open MS Word and click on the “Mailings” tab located on top of your screen next to “References” and “Review.”
                • Step 2: Click on “Envelopes,” and you will see a small envelopes window loading in the middle of your screen
                • Step 3: Click on the “Envelopes” tab in the window and key in the delivery address in the “Delivery Address” section. Include your return address in the lower space in the window.
                • Step 4: Click on “Add to Document,” and the proper formatting for the double-window envelope will automatically be placed on the document. Print the document on a standard piece and fold it accordingly. All the information included should align with the two blank windows.


                Is a regular envelope first class mail?

                Yes, regular envelopes can qualify for first-class mail. As long as they are rectangular and at least 3 ½ inches high x 5 inches long x 0.007 inches thick and no more than 6 1/8 inches high x 11 ½ inches long x ¼ inches thick.

                What size envelope needs extra postage?

                Any envelope that is larger than the maximum dimensions for a United States postal letter, i.e., 6 1/8 inches high x 11 ½ inches long and ¼ inches thick, will require extra postage.

                Final Words

                Whether you are looking to use an envelope for personal use or business, you will always find yourself needing to send out things such as documents, cards and invites. This is why it is important that you understand the different styles of envelopes available and their specific purpose.
