The Guide to Finding the Right Envelope!

Choosing the right envelope sizes for each business application can be hard. There are many different sizes that are best used for specific mailings, and you might want to have different types of envelopes on hand for interoffice mail as well. Since many envelope sizes are labeled by a single number, like #7 or #10, it can be tough to figure out which ones you need. At The Supplies Shops, we’ve put together this handy envelope size guide to help you compare envelopes with various sizes, materials, and closure designs. Check out the graphics above for an overview, then see below for more information about each type of business envelope and to view helpful envelope size charts!

Regular Envelopes

Regular envelopes feature the standard envelope sizes you see used most frequently for mailings. However, there isn’t just one type of business envelope for this category. This product range includes the popular #10 envelope, which measures 4 1/8″ x 9 1/2″ and is often considered to be the “classic” U.S. envelope size for business purposes. In addition, #9 regular envelopes (3-7/8″ x 8-7/8″) are another one of the most popular commercial-sized envelopes available. The #9 envelope style is commonly used as a reply envelope for invoices and business mailings, sent to recipients inside #10 envelopes in order to mail something back to the sender.

Other popular regular envelopes include:

All regular envelopes feature a solid front with no window, and a basic flap on the back. Some regular envelopes have special features, including security tint to conceal the contents, and pre-moistened adhesive flaps for easy closure. Therefore, businesses use these envelopes to send invoices, checks, letters, and other types of mailings. If you need regular business envelopes, you’ll be able to choose from a wide range of colors, including pastels and bright colors.


Window Envelopes

Window envelopes feature one or more openings on the front of the envelope that allows the contents inside the envelope to show through. Single window envelopes have just one opening for the mailing address, whereas double window envelopes have an opening for the return address as well. Full face envelopes have an opening on the entire front of the envelope, giving a view of the contents inside. Choose from a wide array of colors and sizes of envelopes to coordinate with your mailing needs, including window envelopes designed for standard business checks.

Common window envelope sizes:

One thing to keep in mind when ordering window envelopes is whether you need them to go through your printer. If that’s the case, you’ll need envelopes with a thermal window like our digi-clear laser compatible window envelopes that can withstand the high temperatures inside the printer without being warped or melted.


Square Envelopes

Square envelopes are square and symmetrical, appealing to the eye and very stylish. Most square styles have square flaps on the back, but a few have deep triangular contour flaps that nicely offset the square envelope. Sizes range from miniature 5″ x 5″ square envelopes to 13″ x 13″ square envelopes. They are most commonly used with baronial cards for informal mailings, social invitations, and commercial announcements. This type of envelope comes in a wide range of colors, which is great for branding and for invitations to seasonal events or festive occasions. Keep in mind that when mailing square envelopes through the USPS, you will need additional postage because of the shape.

Catalog Envelopes

The main feature of open end envelopes, also known as catalog envelopes, is the placement of the envelope flap on the short end of the envelope. With or without windows, these durable, high-quality envelopes come in brown kraft, white, and bright or pastel colors. With so many options, first select your size and material (paper or Tyvek). Then, select the appropriate closure mechanism: metal clasp, ungummed, remoistening seal, or pressure sensitive seal. There are also clasp envelopes that provide are an alternative to the gum closure. Also, filters in the left column will help you sort for specific needs.

You can choose windowless catalog envelopes or window catalog envelopes. Windowless catalog envelopes ensure that the contents of your package are kept hidden. On the other hand, window catalogs are produced with 28# white sulphite material and have multiple window options so the necessary information on your mail piece can be seen. Catalog envelopes are used for heavy mailing and shipping requirement such as: booklets, bulky documents, catalogs, magazines, sales literature, and more! These envelopes range from 2-1/2″ x 4-1/4″ to 22″ x 27″ to fit any size document.


Booklet Envelopes

Booklet envelopes are designed to accommodate larger and thicker mailings, including annual reports, brochures, catalogs, and sales literature. These envelopes are also ideal for important documents that should not be folded to fit into a standard envelope. They look professional and help to create branding opportunities for your business. These envelopes range from 4-3/16″ x 9-1/2″ to 12″ x 16″ to fit any size document. The 9″ x 12″ booklet envelope is perfect for mailing unfolded sheets of paper. The 5-3/8″ x 8-7/8″ envelope is ideal for mailing a sheet of paper that is folded in half.

One of the biggest decisions you’ll need to make when choosing your booklet envelopes is whether or not to include a window on the front. Some businesses prefer a flat, windowless appearance for these envelopes in order to allow for including a variety of items to be sent and addresses to be printed individually on the envelope itself. However, if you’re planning a big mailing, you can streamline the process by having addresses printed on the document so that it shows through the clear window. Since our booklet envelopes come with such a wide range of envelope window options, including everything from large showcase windows to small corner windows, you can make sure you get a format that’s optimized for your mailing needs.
