An envelope is a packaging product, usually made of flat material such as paper or cardboard, and designed to contain a flat object, which in a postal-service context is usually a letter, card or bills.
The traditional type is made from a sheet of paper cut to one of three shapes: the rhombus (also referred to as a lozenge or diamond), the short-arm cross, and the kite. These designs ensure that in the course of envelope manufacture when the sides of the sheet are folded about a delineated central rectangular area, a rectangular-faced, usually oblong, enclosure is formed with an arrangement of four flaps on the reverse side, which, by virtue of the shapes of sheet traditionally used, is inevitably symmetrical.
International Standard Sizes
International standard ISO 269 defines several standard envelope sizes, which are designed for use with ISO 216 standard paper sizes:
| Format | Dimensions (mm) | Suitable for content format |
|---|---|---|
| DL | 110 × 220 | 1/3 A4 |
| C7/C6 | 81 x 162 | 1/3 A5 |
| C6 | 114 × 162 | A6 (or A4 folded in half twice) |
| C6/C5 | 114 × 229 | 1/3 A4 |
| C5 | 162 × 229 | A5 (or A4 folded in half once) |
| C4 | 229 × 324 | A4 |
| C3 | 324 × 458 | A3 |
| B6 | 125 × 176 | C6 |
| B5 | 176 × 250 | C5 |
| B4 | 250 × 353 | C4 |
| E3 | 280 × 400 | B4 |
There are dozens of sizes of envelopes available. Not all are used for posting mail, but for such things as former pay packets or putting a gift card or a key in. U.S. and Canadian postal regulations differ from those of the rest of the world; although envelopes are still deliverable worldwide by the regulations of the Universal Postal Union, the sorting machines will not accept the international sizes. This is not as much a difference as usually thought, for the location of sending address and return address differ between Germany and France
The designations such as "A2" do not correspond to ISO paper sizes.
