Paper size landscape


Paper size landscape

The paper size landscape comprises the paper sizes used for sheets of paper, as well as the paper sizes used for the cylinders used to make the printing press. The landscape is a system of designations and definitions. The dimension and relative length of the different paper sizes are laid down by several standards bodies including ISO 216 (1961). For the purposes of printing, four important dimension names are (in abbreviated form) imperial, metric, millimetres and points. Other designsations used are inch, centimetre, decimetre, millimetre and gradem (literally "meter line"). The size of a cylinder, i.e. of the interior and exterior diameters and (for large sizes) the number of characters that can be printed on it, are called the quantity (of that size) or "story". The "story" is abbreviated as "Qty" for cylinder and as "qty" for individual sheets, and it can be abbreviated as a comma. In a text where Qty is not important, the nominal size is abbreviated as "Qt".

The size of the paper can be influenced by the intended use, as well as by the use of high-end paper production equipment. For instance, company logos or trademark symbols printed on a paper sheet, or on paper cylinders which are to be used for printing such sheets, have to be of a size that is not obscured by them. The same is true of any process used to enhance the binding of books, such as removing the sheet of paper between the layers of a book. As paper is a raw material, most paper manufacturers have chosen a minimum paper size for standard consumption (about 1.9 billion metric tonnes annually). The minimum size that will be used, depends on the standards that are to be applied for that paper and on the expected usage of the paper.

The origin of the ISO 216 paper sizes can be traced back to the International Chamber of Commerce's code of specifications for paper sizes, CC, CL and CC/CL (from '-short' to '-long' specifications). This code was superseded by the original ISO 216 code.

Paper sizes and paper cutting

A sheet of paper has a physical dimension that is not necessarily just one sheet length, but it may be cut into smaller pieces, e.g. one would have to cut a sheet to create two pieces that are, for instance, long. A sheet that is long would fit
