Letter (paper Size)
Letter (officially ANSI A) is a paper size standard defined in ANSI/ASME Y14.1 by the American National Standards Institute, commonly used as home or office stationery primarily in the United States, Canada, and the Philippines, and variably across Latin America."US Letter" is the primary paper size used in Belize, Canada, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Mexico, Nicaragua, Panama, Philippines, Puerto Rico, United States, Venezuela according to It measures and is similar in use to the A4 paper standard at used by most other countries, defined in ISO 216 by the International Organization for Standardization. Details The Reagan administration made Letter-size paper the norm for US federal forms in the early 1980s; previously, the smaller "official" Government Letter size, (aspect ratio: 1.3125), was used in government, while paper was standard in most other offices. The aspect ratio is ≈ 1.294 and the diagonal is ≈ in length. In the US, paper den ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triangle Tile
A triangle is a polygon with three corners and three sides, one of the basic shapes in geometry. The corners, also called ''vertices'', are zero-dimensional points while the sides connecting them, also called ''edges'', are one-dimensional line segments. A triangle has three internal angles, each one bounded by a pair of adjacent edges; the sum of angles of a triangle always equals a straight angle (180 degrees or π radians). The triangle is a plane figure and its interior is a planar region. Sometimes an arbitrary edge is chosen to be the ''base'', in which case the opposite vertex is called the ''apex''; the shortest segment between the base and apex is the ''height''. The area of a triangle equals one-half the product of height and base length. In Euclidean geometry, any two points determine a unique line segment situated within a unique straight line, and any three points that do not collinearity, all lie on the same straight line determine a unique triangle situa ...

Aspect Ratio
The aspect ratio of a geometry, geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, when the rectangle is oriented as a "landscape format, landscape". The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal Fraction (mathematics), fraction. The values x and y do not represent actual widths and heights but, rather, the proportion between width and height. As an example, 8:5, 16:10, 1.6:1, and 1.6 are all ways of representing the same aspect ratio. In objects of more than two dimensions, such as hyperrectangles, the aspect ratio can still be defined as the ratio of the longest side to the shortest side. Applications and uses The term is most commonly used with reference to: * Graphic / image ** Aspect ratio (image), Image aspect ratio ** Display aspect ratio ** Pape ...

Stationery
Stationery refers to writing materials, including cut paper, envelopes, continuous form paper, and other office supplies. Stationery usually specifies materials to be written on by hand (e.g., letter paper) or by equipment such as computer printers. History of stationery Originally, the term 'stationery' referred to all products sold by a stationer, whose name indicated that his book shop was on a fixed spot. This was usually somewhere near a university, and permanent, while medieval trading was mainly carried on by itinerant peddlers (including chapmen, who sold books) and others (such as farmers and craftsmen) at markets and fairs. It was a unique term used between the 13th and 15th centuries in the manuscript culture. Stationers' shops were places where books were bound, copied, and published. These shops often loaned books to nearby university students for a fee. The books were loaned out in sections, allowing students to study or copy them, and the only way to get the ...

Quarto
Quarto (abbreviated Qto, 4to or 4º) is the format of a book or pamphlet produced from full sheets printed with eight pages of text, four to a side, then folded twice to produce four leaves. The leaves are then trimmed along the folds to produce eight book pages. Each printed page presents as one-fourth size of the full sheet. The earliest known European printed book is a quarto, the '' Sibyllenbuch'', believed to have been printed by Johannes Gutenberg in 1452–53, before the Gutenberg Bible, surviving only as a fragment. Quarto is also used as a general description of size of books that are about 12 inches (30 cm) tall, and as such does not necessarily indicate the actual printing format of the books, which may even be unknown, as is the case for many modern books. These terms are discussed in greater detail in book sizes. Quarto as format A quarto (from Latin , ablative form of , fourth) is a book or pamphlet made up of one or more full sheets of paper on which eight pag ...

Papermaking
Papermaking is the manufacture of paper and cardboard, which are used widely for printing, writing, and packaging, among many other purposes. Today almost all paper is Pulp and paper industry, made using industrial machinery, while handmade paper survives as a specialized craft and a medium for paper art, artistic expression. In papermaking, a dilute suspension consisting mostly of separate cellulose fibres in water is drained through a sieve-like screen, so that a mat of randomly interwoven fibres is laid down. Water is further removed from this sheet by pressing, sometimes aided by suction or vacuum, or heating. Once dry, a generally flat, uniform and strong sheet of paper is achieved. Before the invention and current widespread adoption of automated machinery, all paper was made by hand, formed or laid one sheet at a time by specialized laborers. Even today those who make paper by hand use tools and technologies quite similar to those existing hundreds of years ago, as origin ...

Paper Size
Paper size refers to Technical standard, standardized dimensions for sheets of paper used globally in stationery, printing, and technical drawing. Most countries adhere to the ISO 216 standard, which includes the widely recognized A series (including A4 paper), defined by a consistent aspect ratio of √2. The system, first proposed in the 18th century and formalized in 1975, allows scaling between sizes without distortion. Regional variations exist, such as the #North American paper sizes, North American paper sizes (e.g., Letter (paper size), Letter, Legal paper, Legal, and Ledger paper, Ledger) which are governed by the American National Standards Institute, ANSI and are used in North America and parts of Central and South America. The standardization of paper sizes emerged from practical needs for efficiency. The ISO 216 system originated in late-18th-century Germany as Deutsches Institut für Normung, DIN 476, later adopted internationally for its mathematical precision. ...

Grammage
Grammage and basis weight, in the pulp and paper industry, are the area density of a paper product, that is, its mass per unit of area. Two ways of expressing the area density of a paper product are commonly used: * Expressed in grams (g) per square metre (g/m2), regardless of its thickness ( caliper)International Standard ISO 536: Paper and board – Determination of grammage. International Organization for Standardization, Geneva. (known as ''grammage''). This is the measure used in most parts of the world. It is often notated as ''gsm'' on paper product labels and spec sheets. * Expressed in terms of the mass per number of sheets of a specific paper size (known as ''basis weight''). The convention used in the United States and a few other countries using US-standard paper sizes is pounds (lb) per ream of 500 (or in some cases 1000) sheets of a given (raw, still uncut) basis size. The traditional British practice is pounds per ream of 480, 500, 504, or 516 sheets of a give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
