Envelope Sizes with Corresponding Insert Sizes

Envelope Sizes and Inserts

One of the first steps when deciding what type of mailing you are going to send is the choosing of envelope sizes and inserts. Depending on the situation, type of mailing and results you are looking for, your envelopes can be different. We can print a variety of envelopes and all accompanying insert materials (brochures, letters, response cards). Envelopes don't have to be plain black and white with a stamp on it, they do have a decent amount of design freedom. For examples of some envelope designs check out our portfolio page.

The most commonly used mailing materials in terms of envelopes are the #10 Regular Mailing Envelope and corresponding #9 Reply Envelope. These can be used together for appeal mailings, which will provide the recipient with an outer #10 Regular Mailing Envelope addressed to them and a #9 Reply Envelope inside. Usually these help the recipient fill out information or a check and place it in the #9 Reply Envelope. Providing them with a means of returns significantly increases the chance of them sending something back.

Besides business sized envelopes, the next most popular are the Announcement envelope sizes (displayed below). These hold postcard sized mailing materials, perfect for wedding invitations and assorted events. A familiar combination would be the use of an A7 Envelope with an A6 Response envelope. You can place a post card (or invitation) and A6 Response Envelope into the outer A7 Envelope with addressing on it along with the card you are mailing, that way the recipient can RSVP to the event.
