A0 size paper is 841 by 1,189 mm in size, which is 1 square meter in area and has a 1.414:1 aspect ratio. Each subsequent size is half the area (determined by halving the long dimension).

Glossary
A-series of paper sizes
The ISO A-series of paper sizes is based on the Lichtenberg Ratio, which is an aspect ratio of 1 to the square root of 2. A0
size paper is 841 by 1,189 mm in size, which is 1 square meter in area and has a 1.414:1 aspect ratio. Each subsequent size
is half the area (determined by halving the long dimension). If the value is an odd number (for example, 1,189 mm), then the
subsequent value after halving is truncated (for example, 594 mm). The aspect ratio of 1:1.414 is maintained throughout
the A-series of paper sizes.
basic size
Basic size is a specified size for a grade of paper. Basic sizes have evolved from custom and usage.
basis weight
Basis weight is the weight of a ream of paper (500 sheets) that has been cut to the basic size. Basis weight is an important
characteristic of paper. Paper that is too light or too heavy can cause misfeeds, misstacking, jams, poor print quality, or
excessive mechanical wear to the printer.
brightness
Brightness refers to the reflectance and whiteness of a sheet of paper. Higher brightness papers are more expensive to
produce and are usually associated with higher quality.
caliper
Caliper is the thickness of a sheet of paper or other print media. It is typically specified in mils (one-thousandth of an inch) or
millimeters. It is closely associated with paper weight but not directly associated, because some papers have more bulk
(more density) than others.
carrier sheet
The carrier sheet is the sheet to which labels are temporarily attached. Usually this sheet has a “slick” feeling or appears
shiny.
composition
Composition (furnish) is the mixture of various materials, such as fiber, filler, sizing materials, and other additives, that are
used to make the paper stock. Fillers such as calcium carbonate, clay, or talc are added to paper to fill in the spaces between
fibers.
For optimum performance of your HP LaserJet printer, use paper that is made from 100 percent chemical wood pulp or
cotton fiber. Recycled paper, made with no more than 5 percent groundwood, is also acceptable. To ensure that paper of a
special fiber composition will work correctly in your printer, test it before purchasing large quantities.
copier paper
A grade of paper that is suitable for printing in the electrophotographic process. This paper is characterized by having a
smooth finish, heat stability, non-curling qualities, and good aesthetic properties (such as color, brightness, and cleanliness).
curl
The amount of curvature or wave in a sheet before or after printing. Sheets might curl before printing if they are exposed to
humid conditions or very dry conditions. Residual stresses in the sheet or high moisture content can also affect the level of
