In typography and handwriting, a descender is the portion of a letter that extends below the baseline of a font.
For example, in the letter y, the descender is the "tail", or that portion of the diagonal line which lies below the v created by the two lines converging. In the letter p, it is the stem reaching down past the ɒ.
In most fonts, descenders are reserved for lowercase characters such as g, j, q, p, y, and sometimes f. Some fonts, however, also use descenders for some numerals (typically 3, 4, 5, 7, and 9). Such numerals are called old-style numerals. (Some italic fonts, such as Computer Modern italic, put a descender on the numeral 4 but not on any other numerals. Such fonts are not considered old-style.) Some fonts also use descenders for the tails on a few uppercase letters such as J and Q. [1]
The parts of characters that extend above the x-height of a font are called ascenders. [2]
Descenders are often reduced in small-print typefaces for uses such as newspapers, directories or pocket Bibles to fit more text on a page. More radically, on 20 May 1802 Philip Rusher of Banbury patented a new Patent Type with eliminated descenders and shortened ascenders. [3] [4] [5] [6] The type did not prove successful, nor did another use in 1852. [7] [8] The Art Nouveau display typeface Hobo and headline typeface Permanent Headline which also eliminate descenders have both been somewhat popular since. [9]
Some early computer displays (for example, the Compukit UK101) and printers (for example, the Commodore 4022 [10] ) restricted the vertical spacing of characters so that there was no space for correct display of descenders. Instead, characters with descenders were displaced vertically upwards so that the bottom of the descender was aligned with the baseline. Contemporary systems that did not have this restriction were described as supporting true descenders.
Some type designers have observed the “tails” of some Thai glyphs to be analogues to the descenders. (e.g. ฤ) [11] [12] Other authors have also mentioned pedestals/feet to be analogues to the descenders. (e.g. ฎ, ฏ, ญ and ฐ) [13] [14]
Typography is the art and technique of arranging type to make written language legible, readable and appealing when displayed. The arrangement of type involves selecting typefaces, point sizes, line lengths, line spacing, letter spacing, and spaces between pairs of letters. The term typography is also applied to the style, arrangement, and appearance of the letters, numbers, and symbols created by the process. Type design is a closely related craft, sometimes considered part of typography; most typographers do not design typefaces, and some type designers do not consider themselves typographers. Typography also may be used as an ornamental and decorative device, unrelated to the communication of information.
Palatino is an old-style serif typeface designed by Hermann Zapf, initially released in 1949 by the Stempel foundry and later by other companies, most notably the Mergenthaler Linotype Company.
Type design is the art and process of designing typefaces. This involves drawing each letterform using a consistent style. The basic concepts and design variables are described below.
In typography, a serif is a small line or stroke regularly attached to the end of a larger stroke in a letter or symbol within a particular font or family of fonts. A typeface or "font family" making use of serifs is called a serif typeface, and a typeface that does not include them is sans-serif. Some typography sources refer to sans-serif typefaces as "grotesque" or "Gothic" and serif typefaces as "roman".
A typeface is a design of letters, numbers and other symbols, to be used in printing or for electronic display. Most typefaces include variations in size, weight, slope, width, and so on. Each of these variations of the typeface is a font.
Garamond is a group of many serif typefaces, named for sixteenth-century Parisian engraver Claude Garamond, generally spelled as Garamont in his lifetime. Garamond-style typefaces are popular and particularly often used for book printing and body text.
Frutiger is a series of typefaces named after its Swiss designer, Adrian Frutiger. Frutiger is a humanist sans-serif typeface, intended to be clear and highly legible at a distance or at small text sizes. A popular design worldwide, type designer Steve Matteson described its structure as "the best choice for legibility in pretty much any situation" at small text sizes, while Erik Spiekermann named it as "the best general typeface ever".
In typography, italic type is a cursive font based on a stylised form of calligraphic handwriting. Along with blackletter and roman type, it served as one of the major typefaces in the history of Western typography.
Courier is a monospaced slab serif typeface commissioned by IBM and designed by Howard "Bud" Kettler (1919–1999) in the mid-1950s. The Courier name and typeface concept are in the public domain. Courier has been adapted for use as a computer font, and versions of it are installed on most desktop computers.
Text figures are numerals designed with varying heights in a fashion that resembles a typical line of running text, hence the name. They are contrasted with lining figures, which are the same height as upper-case letters. Georgia is an example of a popular typeface that employs text figures by default.
In typography, the x-height, or corpus size, is the distance between the baseline and the mean line of lowercase letters in a typeface. Typically, this is the height of the letter x in the font, as well as the letters v, w, and z. One of the most important dimensions of a font, x-height defines how high lowercase letters without ascenders are compared to the cap height of uppercase letters.
Caslon is the name given to serif typefaces designed by William Caslon I in London, or inspired by his work.
Bookman, or Bookman Old Style, is a serif typeface. A wide, legible design that is slightly bolder than most body text faces, Bookman has been used for both display typography, for trade printing such as advertising, and less commonly for body text. In advertising use it is particularly associated with the graphic design of the 1960s and 1970s, when revivals of it were very popular.
Modern typographers view typography as a craft with a very long history tracing its origins back to the first punches and dies used to make seals and coinage currency in ancient times. The basic elements of typography are at least as old as civilization and the earliest writing systems—a series of key developments that were eventually drawn together into one systematic craft. While woodblock printing and movable type had precedents in East Asia, typography in the Western world developed after the invention of the printing press by Johannes Gutenberg in the mid-15th century. The initial spread of printing throughout Germany and Italy led to the enduring legacy and continued use of blackletter, roman, and italic types.
Caledonia is a serif typeface designed by William Addison Dwiggins in 1938 for the Mergenthaler Linotype Company and commonly used in book design. As a transitional serif design, one inspired by the Scotch Roman typefaces of the early nineteenth century, Caledonia has a contrasting design of alternating thick and thin strokes, a design that stresses the vertical axis and sharp, regular serifs on ascenders and descenders.
Legibility is the ease with which a reader can decode symbols. In addition to written language, it can also refer to behaviour or architecture, for example. From the perspective of communication research, it can be described as a measure of the permeability of a communication channel. A large number of known factors can affect legibility.
Typeface anatomy describes the graphic elements that make up letters in a typeface.
Typefaces are born from the struggle between rules and results. Squeezing a square about 1% helps it look more like a square; to appear the same height as a square, a circle must be measurably taller. The two strokes in an X aren't the same thickness, nor are their parallel edges actually parallel; the vertical stems of a lowercase alphabet are thinner than those of its capitals; the ascender on a d isn't the same length as the descender on a p, and so on. For the rational mind, type design can be a maddening game of drawing things differently in order to make them appear the same.
Ehrhardt is an old-style serif typeface released by the British branch of the Monotype Corporation in 1938. Ehrhardt is a modern adaptation of printing types of "stout Dutch character" from the Dutch Baroque tradition sold by the Ehrhardt foundry in Leipzig. These were cut by the Hungarian-Transylvanian pastor and punchcutter Miklós (Nicholas) Tótfalusi Kis while in Amsterdam in the period from 1680 to 1689.
Thai typography concerns the representation of the Thai script in print and on displays, and dates to the earliest printed Thai text in 1819. The printing press was introduced by Western missionaries during the mid-nineteenth century, and the printed word became an increasingly popular medium, spreading modern knowledge and aiding reform as the country modernized. The printing of textbooks for a new education system and newspapers and magazines for a burgeoning press in the early twentieth century spurred innovation in typography and type design, and various styles of Thai typefaces were developed through the ages as metal type gave way to newer technologies. Modern media is now served by digital typography, and despite early obstacles including lack of copyright protection, the market now sees contributions by several type designers and digital type foundries.
Rusher's Patent Types were the characters of an experimental serif typeface invented, patented and promoted by Philip Rusher in Banbury, England, from 1802 onwards. The typeface removed the descenders from the lower-case letters and shortened the ascenders, which Rusher hoped would make the typeface "more uniform" and save paper. The typeface was used for a few books but did not become popular.
