Legibility
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. In everyday language, legibility is commonly used as a synonym for readability. In graphic design, however, legibility is often distinguished from readability. Readability is the ease with which a reader can follow and understand words, sentences and paragraphs. While legibility usually refers to the visual clarity of individual symbols, readability is more about their arrangement or even the choice of words. Legibility is a component of readability. The legibility of text is most often examined by controlled deterioration of viewing conditions and determination of threshold detection. Not all writing benefits from optimizing for legibility.

Typography
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 ( leading), and letter-spacing (tracking), as well as adjusting the space between pairs of letters (kerning). 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. Typography is the work of typesetters (also known as compositors), typographers, graphic designers, art directors, manga artists, comic book artists, and, now, anyone who arranges words, letters, numbers ...

Readability
Readability is the ease with which a reader can understand a written text. In natural language, the readability of text depends on its content (the complexity of its vocabulary and syntax) and its presentation (such as typographic aspects that affect legibility, like font size, line height, character spacing, and line length). Researchers have used various factors to measure readability, such as: * Speed of perception * Perceptibility at a distance * Perceptibility in peripheral vision * Visibility * Reflex blink technique * Rate of work (reading speed) * Eye movements * Fatigue in reading * Cognitively-motivated features * Word difficulty * N-gram analysis * Semantic Richness Higher readability eases reading effort and speed for any reader, but it makes a larger difference for those who do not have high reading comprehension. Readability exists in both natural language and programming languages though in different forms. In programming, things such as programmer comments, c ...

Letter Case
Letter case is the distinction between the Letter (alphabet), letters that are in larger uppercase or capitals (or more formally ''majuscule'') and smaller lowercase (or more formally ''minuscule'') in the written representation of certain languages. The writing systems that distinguish between the upper and lowercase have two parallel sets of letters, with each letter in one set usually having an equivalent in the other set. The two case variants are alternative representations of the same letter: they have the same name and pronunciation and are treated identically when sorting in alphabetical order. Letter case is generally applied in a mixed-case fashion, with both upper and lowercase letters appearing in a given piece of text for legibility. The choice of case is often prescribed by the grammar of a language or by the conventions of a particular discipline. In orthography, the uppercase is primarily reserved for special purposes, such as the first letter of a Sentence (ling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerning
In typography, kerning is the process of adjusting the spacing between Character (symbol), characters in a Typeface#Proportion, proportional font, usually to achieve a visually pleasing result. Kerning adjusts the space between individual letterforms, while Letter-spacing, tracking (letter-spacing) adjusts spacing uniformly over a range of characters. In a well-kerned font, the two-dimensional blank spaces between each pair of characters all have a visually similar area. The term "keming" is sometimes used informally to refer to poor kerning (the letters r and n placed too close together being easily mistaken for the letter m). The related term ''kern'' denotes a part of a type letter that overhangs the edge of the Movable type, type block. Metal typesetting The source of the word ''kern'' is from the French word , meaning "projecting angle, quill of a pen". The French term originated from the Latin , , meaning "hinge". In the days when all type was cast metal, the parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Line Length
In typography, line length is the width of a block of typeset text, usually measured in units of length like inches or points or in characters per line (in which case it is a measure). A block of text or paragraph has a maximum line length that fits a determined design. If the lines are too short then the text becomes disjointed; if they are too long, the content loses rhythm as the reader searches for the start of each line. Line length is determined by typographic parameters based on a formal grid and template with several goals in mind: balance and function for fit and readability with a sensitivity to aesthetic style in typography. Typographers adjust line length to aid legibility or copy fit. Text can be flush left and ragged right, flush right and ragged left, or justified where all lines are of equal length. In a ragged right setting, line lengths vary to create a ragged right edge. Sometimes this can be visually satisfying. For justified and ragged right settings typo ...

Serif
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 (or serifed typeface), and a typeface that does not include them is sans-serif. Some typography sources refer to sans-serif typefaces as "grotesque" (in German, ) or "Gothic", and serif typefaces as "roman". Origins and etymology Serifs originated from the first official Greek writings on stone and in Latin alphabet with inscriptional lettering—words carved into stone in Roman antiquity. The explanation proposed by Father Edward Catich in his 1968 book ''The Origin of the Serif'' is now broadly but not universally accepted: the Roman letter outlines were first painted onto stone, and the stone carvers followed the brush marks, which flared at stroke ends and corners, creating serifs. Another theory is that serifs were devised to neate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Counter (typography)
In typography, a counter is the area of a letter that is entirely or partially enclosed by a letter form or a symbol (the counter-space/the hole of). The stroke that creates such a space is known as a "bowl". Latin letters containing closed counters include A, B, D, O, P, Q, R, a, b, d, e, g, o, p, and q. Latin letters containing open counters include c, f, h, s etc. The digits 0, 4, 6, 8, and 9 also possess a counter. An aperture is the opening between an open counter and the outside of the letter. The lowercase ' g' has two typographic variants: the single-storey 'g' has one closed counter and one open counter (and hence one aperture); the double-storey '' has two closed counters. The digit ' 4' also has two typographic variants: the closed-top variant '4' has a closed counter, and an open-top (e.g. handwritten) '' has an open counter. Open and closed apertures Different typeface styles have different tendencies to use open or more closed apertures. This de ...

Leading
In typography, leading ( ) is the space between adjacent lines of type; the exact definition varies. In hand typesetting, leading is the thin strips of lead (or aluminium) that were inserted between lines of type in the composing stick to increase the vertical distance between them. The thickness of the strip is called leading and is equal to the difference between the size of the type and the distance from one baseline to the next. For instance, given a type size of 10 points and a distance between baselines of 12 points, the leading would be 2 points. The term is still used in modern page-layout software such as QuarkXPress, the Affinity Suite, and Adobe InDesign. Consumer-oriented word-processing software often talks of line spacing or, more accurately, interline spacing. Origins The word comes from lead strips that were put between set lines of lead type, hence the pronunciation "ledding" and not "leeding". The practice became popular in the eighteenth ...

Ascender (typography)
In typography and handwriting, an ascender is the portion of a minuscule letter in a Latin-derived alphabet that extends above the mean line of a font. That is, the part of a lower-case letter that is taller than the font's x-height. Ascenders, together with descenders, increase the recognizability of words. For this reason, many situations that require high legibility such as road signs avoid using solely capital letters (i.e. all-caps). Studies made at the start of the construction of the British motorway network concluded that words with mixed-case letters were much easier to read than "all-caps" and a special font was designed for motorway signs. These then became universal across the UK. See Road signs in the United Kingdom. In many fonts intended for body text, such as Bembo and Garamond Garamond is a group of many serif typefaces, named for sixteenth-century Parisian engraver Claude Garamond, generally spelled as Garamont in his lifetime.

Display Typeface
A display typeface is a typeface that is intended for use at large sizes for headings, rather than for extended passages of body text. Display typefaces will often have more eccentric and variable designs than the simple, relatively restrained typefaces generally used for body text. They may take inspiration from other genres of lettering, such as handpainted signs, calligraphy or an aesthetic appropriate to their use, perhaps ornamented, exotic, abstracted or drawn in the style of a different writing system. Several genres of font are particularly associated with display setting, such as slab serif, script font, reverse-contrast and to a lesser extent sans serif. Walter Tracy defines display typefaces in the metal type sense as "sizes of type over 14 point" and in design that "text types when enlarged can be used for headings, display types, if reduced, cannot be used for text setting." Titling fonts are a subset of display typefaces which are typically used for headlines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dyslexia
Dyslexia, also known until the 1960s as word blindness, is a disorder characterized by reading below the expected level for one's age. Different people are affected to different degrees. Problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing words when reading aloud and understanding what one reads. Often these difficulties are first noticed at school. The difficulties are involuntary, and people with this disorder have a normal desire to learn. People with dyslexia have higher rates of attention deficit hyperactivity disorder (ADHD), developmental language disorders, and difficulties with numbers. Dyslexia is believed to be caused by the interaction of genetic and environmental factors. Some cases run in families. Dyslexia that develops due to a traumatic brain injury, stroke, or dementia is sometimes called "acquired dyslexia" or alexia. The underlying mechanisms of dyslexia result from differ ...

Typographic Alignment
In typesetting and page layout, alignment or range is the setting of text flow or image placement relative to a page, column (measure), table cell, or tab (and often to an image above it or under it). The type alignment setting is sometimes referred to as text alignment, text justification, or type justification. The edge of a page or column is known as a ''margin'', and a gap between columns is known as a ''gutter''. Basic variations There are four basic typographic alignments: * flush left—the text is aligned along the left margin or gutter, also known as ''left-aligned'', ''ragged right'' or ''ranged left''; * flush right—the text is aligned along the right margin or gutter, also known as ''right-aligned'', ''ragged left'' or ''ranged right''; * justified—text is aligned along the left margin, with letter-spacing and word-spacing adjusted so that the text falls flush with both margins, also known as ''fully justified'' or ''full justification''; * centered—text is al ...
