The pocket envelope is smaller than a lot of the other envelope types. You can find many types of pocket envelopes and people tend to use these for coupons, photographs, mail receipts, etc.

Announcement envelopes are popular for sending out invitations. Baronial envelopes are for announcements and a lot of people use these. People use announcement envelopes to send greetings cards, small booklets, and brochures as well as invitations.

Another envelope type is the square envelope. These envelopes are completely square and often people use these for fancy invitations. Then there are wallet envelopes that businesses use in mailing machines due to their straight flaps allowing automatic insertion of materials. Many direct mail pieces arrive in wallet envelopes.

People use booklet envelopes to send brochures, booklets, photographs, statements, and so on. There are different sizes of booklet envelopes and a lot of businesses use a large size so that they can send documents without the need to fold them.

Another popular envelope is the catalog envelope. These are popular with businesses that send out catalogs, reports, insurance policies, magazines, etc. Job hunters use catalog envelopes to send their resumes to companies. Users tend to go with a larger size catalog envelope so that they do not have to fold the materials inside it.

Letter Size Envelopes and Standard Envelope Sizes

Is there a standard letter envelopes size? No there isn’t. Letter paper used in the United States is 8.5 inches by 11 inches. You can use different-sized envelopes to send a letter-sized document.

A lot of businesses and private individuals use the number 10 envelope size to send folded letter paper. Some businesses do not want to fold a letter-size document so they will use catalog envelopes.

There is no doubt that the #10 envelope size is the most popular used for letter-sized paper. It is one of those envelope sizes considered to be a standard-sized envelope. While there is really no standard size envelope or standard envelopes 10 size is probably the closest to a standard envelope size.

What about the standard business envelope size? Well, again you are looking at size 10 envelopes as standard-sized envelopes for business because they are just so popular.

If you base standard envelope sizes on popularity then the #10 envelope size and even the #9 envelope size come into this category. But they are certainly not the only game in town and more and more people are now using the A4 envelope size as well as the A5 sized envelope.
