A large envelope is a rectangular piece of mail that is no thicker than 3/4 inch. They are frequently known as "flats." There are also half-toned and quarter-toned letters, which are similar to large envelopes but have been processed through a mailing machine rather than by hand.
Large envelopes take up more space in your mailbox and therefore may not be able to fit all of your mail together with other letters. But they provide more room for writing so it's easier to send off multiple messages at once.
There are two types of postmarks used on large letters: address only and address plus postmark. With the address-only postmark, only the address goes onto the letter. The rest of the space is left blank. With the address-plus-postmark system, both the address and the date go on the letter. This allows you to place a postmark over pre-printed postal marks such as bar codes or stamps.
Large envelopes are used when you want to make a statement with your lettering or when you need lots of space to write down all of your thoughts about what you want to say to everyone who receives your letter.
Large envelopes (also known as flat mail) are First-Class Mail envelopes that are larger than 6 1/8" in height, 11 1/2" in width, or 1/4" in thickness. Marketing bulletins, product catalogues, and legal communications are common contents of large envelopes. Large envelopes carry more postage than regular-size letters.
First-Class Mail is the highest-quality mail classification system in use by the United States Postal Service. It consists of nine different rates based on such factors as weight, size, and material of the envelope. Smaller sizes and lighter weights of mail qualify for lower rates of postage. For example, an 8 1/2 x 11 inch sheet of paper weighs 2 3/4 ounces, so it can be mailed at first-class rates if it meets other size requirements.
In addition to size, height is also used to classify large envelopes. Flat mail that is 6 1/8" tall or greater is considered large. Letters up to 5 7/8" tall are called standard-sized letters.
The third factor used to classify large letters is width. The mailing address must be printed on both top and bottom surfaces of the letter to be counted as one-half of first-class postage. If only one side of the letter is addressed, it is considered partial mail and will be charged at a higher rate. The fourth factor is thickness.
The terms "big envelopes" and "flats" are used synonymously. Flats, whatever you name them, must have the following features: Have at least one dimension that is larger than 6-1/8 inch high, 11-1/2 inch long, or 1/4 inch thick. Sizes cannot be larger than 12 inches high, 15 inches long, or 3/4 inch thick. To be used for huge envelopes and flats

An envelope is a popular type of packaging that is often composed of thin, flat material. It is intended to hold a flat object, such as a letter or a card. Envelopes are traditionally fashioned from sheets of paper cut into one of three shapes: a rhombus, a short-arm cross, or a kite. They may also be made from other materials, such as plastic or aluminum. The term "envelope" may also be applied to similar containers used for different purposes. For example, an envelope in a shipping company is where you send items purchased with a credit card; a bank envelope contains information about your account balance and activity; and an airmail envelope goes through a mail facility together with letters, packages, and flyers being sent overseas.
Rhombuses are the most common shape for envelopes, but they can also be made from half-sheets of material if necessary. Half-sheets are cut from a single sheet of paper, usually when only part of the page needs to be printed. These pieces are then folded along parallel lines cutting the sheet in two equal parts. The halves are then joined along their shorter sides by either gluing or stapling them together. Rhombuses can be used for mailing cards because they do not need to be sealed. However, if you intend to keep the contents private, it is best to use something else instead.
Regular envelopes are the most common type of business envelope. The popular # 10 envelope, which measures 4 1/8" by 9 1/2", is included in this product line. Regular envelopes all have a solid front with no window and a simple flap on the rear.
There are two types of regular business envelopes: one-piece with flaps and two-piece without flaps. One-piece envelopes are sealed together at the top, bottom, and back. Two-piece envelopes have separate top and bottom sections that are stapled or glued together.
The thickness of regular envelopes varies depending on how much writing they will hold. A standard letter-size sheet of paper is 8 1/4" x 11", so a regular envelope can handle up to four letters per sheet. If you need an envelope for something longer, such as an acceptance letter for a job application, ask your local mail carrier for some extra-thick letters. These are available in several sizes from which to choose.
Envelopes are used to protect written messages while they are in transit from one person to another. When someone sends you an email, it goes into a special type of envelope called an "electronic message."
People write letters because it's easier to think things through than in an email.
