SQUARE ENVELOPE

ENVELOPE TYPES AND SIZES

Envelopes come in a variety of sizes and styles. They are used for a variety of purposes, from mailing to security to protection of the enclosed contents. They can be used commercially for business correspondence, or for personalized mailings such as letters, invitations, and announcements. The type of envelope you use corresponds directly to the purpose/function you are trying to accomplish. A business mailing an invoice would not use the same envelope size and style as a bride to be sending her wedding invitations.

 

If mailings are involved, Post Office regulations may also be part of the decision making, as using non-standard sizes will affect postage rates. Not only do the sizes vary, but there can also be customization on the way the envelope is folded to create various flaps and seams. Commercial flaps are the most common, but square flaps, wallet flaps, side seams, and policy flaps are also prevalent. Clear windows are also available and an option. At AlphaGraphics Chicago North, we have a variety of envelopes and styles to help our customers accomplish whatever goal they are trying to achieve. We can also create custom sized, custom windowed, and custom folded envelopes for our customers if requested. 

 

The most common envelope type and size is a commercial #10 envelope. This style is typically used by businesses for mailing business correspondence and generally contains a c or z fold letter size sheet(s). This envelope is sized to 4.125” x 9.5”. Personalized company logos, names, and address information can be printed on the envelope to give a professional look. At AlphaGraphics Chicago North, we typically print these kinds of envelopes on our Ryobi offset press or our Xante Digital Press. Commercial #9 envelopes are slightly smaller than #10 envelopes and are also common for mailing business correspondence or payment checks businesses mail to the vendors. The size of these envelopes is 3.875” x 8.875”. #10 envelopes are also typically used by consumers to mail letters to family and friends. 

 

Booklet and catalog envelopes are typically oversized and contain letter-size contents that are not folded. For example, a size 9 booklet/catalog envelope is sized to 8.75” x 11.5” and can hold standard letter size (8.5” x 11”) sheets. The difference between booklet and catalog is in reference to where the flap/envelope opening is. On booklet envelopes, the opening is on the long edge of the envelope, whereas on a catalog style, the opening is on the short edge of the envelope. At AlphaGraphics Chicago North, we can print on both styles, and these oversized envelopes are available in a variety of sizes depending on our customer needs.

 

Other options with envelopes include baronial, announcement, and square envelopes. These are typically used for wedding invitations, birthday cards, graduations, and other specialized events. Baronial envelopes have a pointed, more triangular flap, and are typically smaller than #10 envelopes. They are typically measured in bars when relating to the size. A 4 Bar Baronial envelope for example is sized to 3.625” x 5.125”. If you have received a wedding invitation in the mail, you likely have seen a baronial envelope as the reply back envelope to house your RSVP. Announcement envelopes, also called the A-Style, are typically used for invitations to special events such as weddings, graduations, or for sending greeting cards. They are generally more rectangular and taller than #10s, for example, a size A-7 announcement envelope is sized to 5.25” x 7.25” and would be ideal to send or store a 5” x 7” greeting card. And, of course, there are many other standard sizes of both baronial and announcement sizes that correspond to other common sizes of cards and invitations.

We have a wide range of envelope offerings from most common standard envelopes all the way to a purely customized design and size. Our experienced team members are always ready and are able to guide you to the proper choices for your envelope enclosure needs. Give us a call today!
