Have you ever really taken a look at the packs of computer paper you buy? Or can you automatically eye the standard paper used for letters and academic purposes? You have more than likely heard of A5 or Tabloid , but for many, the only two page sizes that really matter are A4 or Letter. But there exist a number of paper sizes that are relevant to our everyday lives, and knowing them can save you time and money when printing and copying. Though other paper size standards exist, there are two predominant systems in use today.
They are the international and North American systems. As the term implies, the international standard, also known as the ISO standard, is used throughout the world. It is based on an aspect ratio of the square root of two, like the side of a square and its diagonal.
This idea was originally proposed by the German scientist Georg Christoph Lichtenberg in In , Dr. This new standard was known as the DIN standard. The system became widely used during World War II. The most commonly used ISO paper size is A4. The current sizes are based on traditional sizes such as Letter 8. Though the sizes now begin with ANSI, they are nevertheless based on the traditional sizes.
The most convenient and distinguishing characteristic of ISO paper is that each format has an aspect ratio equal to the square root of two which makes it simple to enlarge or reduce a document for printing on another ISO paper format. The most popular series of the ISO standard is the A series. The most widely used paper of this series is the A4 format. All paper sizes of this series have a name that consists of an A followed by a number. The larger that number, the smaller the paper. The basis for the whole system is the A0 format which has an area of one square meter.
Figuring out the dimensions of the subsequent paper sizes does not require any real mathematical strain since each ensuing size can be created by simply folding the paper in half with the crease parallel to the shortest sides. Take note that the height of A1 is equal to the width of A0. The B series was brought into being to provide a wider range of paper sizes, where as the C series is used only for envelopes.
The B paper sizes are a bit larger than their A series counterparts and are based on the geometric mean of two consecutive A series sheets.
The C series was introduced to provide an envelope with enough space for an A series sheet.

Cut that 44 inches in half, twice, and you end up with paper 11 inches long. Some of this history is recorded in the Robert C Williams Museum of Papermaking at Georgia Institute of Technology in Atlanta where you can find some of the original papermaking molds. These large sheets were known as foolscap with the dimensions of 8. So as it evolved, it seems lawyers would simply cut the foolscap in half and use the sheets for official documents.
Legal paper as we discussed does not get along with printers, photocopiers, and fax machines. You often have to manually set the machine to print a legal document every single time.
The answer to this logical question is simple. Just like lawyers use legal pads as they are easier on the eyes than the allegedly bright white paper.
So for professionals who have to read and write quite a lot, it makes sense to use something easier on the eyes.
