In typography, text or font in all caps (short for "all capitals") contains capital letters without any lowercase letters. For example:
THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG.
All-caps text can be seen in legal documents, advertisements, newspaper headlines, and the titles on book covers. Short strings of words in capital letters appear bolder and "louder" than mixed case, and this is sometimes referred to as "screaming" or "shouting". [1] All caps can also be used to indicate that a given word is an acronym.
Studies have been conducted on the readability and legibility of all caps text. Scientific testing from the 20th century onward has generally indicated that all caps text is less legible and readable than lower-case text. [2] [3] In addition, switching to all caps may make text appear hectoring and obnoxious for cultural reasons, since all-capitals is often used in transcribed speech to indicate that the speaker is shouting. [4] All-caps text is common in comic books, as well as on older teleprinter and radio transmission systems, which often do not indicate letter case at all. [5] [6]
In professional documents, a commonly preferred alternative to all caps text is the use of small caps to emphasise key names or acronyms (for example, Text in Small Caps), or the use of italics or (more rarely) bold. [7] In addition, if all caps must be used it is customary to slightly widen the spacing between the letters, by around 10 per cent of the point height. This practice is known as tracking or letterspacing. [8] Some digital fonts contain alternative spacing metrics for this purpose. [9]
Messages completely in capital letters are often equated on social media to shouting and other impolite or argumentative behaviors. [10] This became a mainstream interpretation with the advent of networked computers, from the 1980s onward. However, a similar interpretation was already evidenced by written sources that predated the computing era, in some cases by at least a century, and the textual display of shouting or emphasis was still not a settled matter by 1984. The following sources may be relevant to the history of all caps: [11]
Before the development of lower-case letters in the 8th century, texts in the Latin alphabet were written in a single case, which is now considered to be capital letters. Text in all caps is not widely used in body copy. The major exception to this is the so-called fine print in legal documents.
Capital letters have been widely used in printed headlines from the early days of newspapers until the 1950s. In the 1990s, more than three-quarters of newspapers in the western world used lower-case letters in headline text. Discussion regarding the use of all caps for headlines centers on the greater emphasis offered by all caps versus the greater legibility offered by lower-case letters. [2] Colin Wheildon conducted a scientific study with 224 readers who analyzed various headline styles and concluded that "Headlines set in capital letters are significantly less legible than those set in lower case." [15]

All caps typography was common on teletype machines, such as those used by police departments, news, and the United States' then-called Weather Bureau, as well as early computers, such as certain early Apple II models and the ZX81, which had a limited support for lower-case text. This changed as full support of ASCII became standard, allowing lower-case characters.
Some Soviet computers, such as Radio-86RK, Vector-06C, Agat-7, use 7-bit encoding called KOI-7N2, where capital Cyrillic letters replace lower-case Latin letters in the ASCII table, so can display both alphabets, but all caps only. Mikrosha is switchable to KOI-7N1, in this mode, it can display both caps and lower-case, but in Cyrillic only. Other Soviet computers, such as BK0010, MK 85, Corvette and Agat-9, use 8-bit encoding called KOI-8R, they can display both Cyrillic and Latin in caps and lower-case.[ citation needed ]
Many, but not all NES games use all caps because of tile graphics, where charset and tiles share the same ROM. Game designers often choose to have less characters in favor of more tiles.[ citation needed ]
With the advent of the bulletin board system, or BBS, and later the Internet, typing messages in all caps commonly became closely identified with "shouting" or attention-seeking behavior, and may be considered rude. Its equivalence to shouting traces back to at least 1984 and before the Internet, back to printed typography usage of all capitals to mean shouting. [16]
For this reason, etiquette generally discourages the use of all caps when posting messages online. While all caps can be used as an alternative to rich-text "bolding" for a single word or phrase, to express emphasis, repeated use of all caps can be considered "shouting" or irritating. [17]
Some aspects of Microsoft's Metro design language involve the use of all caps headings and titles. This has received particular attention when menu and ribbon titles appeared in all caps in Visual Studio 2012 and Office 2013, respectively. Critics have compared this to a computer program shouting at its user. Information technology journalist Lee Hutchinson described Microsoft's using the practice as "LITERALLY TERRIBLE ... [it] doesn't so much violate OS X's design conventions as it does take them out behind the shed, pour gasoline on them, and set them on fire." [18]
In programming, writing in all caps (possibly with underscores replacing spaces) is an identifier naming convention in many programming languages that symbolizes that the given identifier represents a constant.
A practice exists (most commonly in Francophone countries) [19] of distinguishing the surname from the rest of a personal name by stylizing the surname only in all caps. This practice is also common among Japanese, when names are spelled using Roman letters. [20]
In April 2013, the U.S. Navy moved away from an all caps-based messaging system, which was begun with 1850s-era teleprinters that had only uppercase letters. [21] The switch to mixed-case communications was estimated to save the Navy $20 million a year and is compliant with current Internet protocol. [21]
An antiquated practice that still remains in use, especially by older American lawyers who grew up before the arrival of computers, is to use all caps text for text that is legally required to be emphasised and clearly readable. [22] The practice dates to the period of typewriters, which generally did not offer bold text, small capitals, or the opportunity to add marginal notes emphasising key points.
Legal writing expert Bryan A. Garner has described the practice as "ghastly". [23] A 2020 study found that all-caps in legal texts is ineffective and is, in fact, harmful to older readers. [24] In 2002, a US court spoke out against the practice, ruling that simply making text all-capitals has no bearing on whether it is clear and easily readable:
Lawyers who think their caps lock keys are instant "make conspicuous" buttons are deluded. In determining whether a term is conspicuous, we look at more than formatting. A term that appears in capitals can still be inconspicuous if it is hidden on the back of a contract in small type. Terms that are in capitals but also appear in hard-to-read type may flunk the conspicuousness test. A sentence in capitals, buried deep within a long paragraph in capitals will probably not be deemed conspicuous...it is entirely possible for text to be conspicuous without being in capitals. [25]
Certain musicians—such as Marina, Finneas, who are both known mononymously, and MF DOOM—as well as some bands such as Haim and Kiss—have their names stylised in all caps. Additionally, it is common for bands with vowelless names (a process colourfully known as "disemvoweling") to use all caps, with prominent examples including STRFKR, MSTRKRFT, PWR BTTM, SBTRKT, JPNSGRLS (now known as Hotel Mira), BLK JKS, MNDR, and DWNTWN.
Miles Tinker, renowned for his landmark work, Legibility of Print, performed scientific studies on the legibility and readability of all-capital print. His findings were as follows:
All-capital print greatly retards speed of reading in comparison with lower-case type. Also, most readers judge all capitals to be less legible. Faster reading of the lower-case print is due to the characteristic word forms furnished by this type. This permits reading by word units, while all capitals tend to be read letter by letter. Furthermore, since all-capital printing takes at least one-third more space than lower case, more fixation pauses are required for reading the same amount of material. The use of all capitals should be dispensed with in every printing situation. [26]
According to Tinker, "As early as 1914, Starch reported that material set in Roman lower case was read somewhat faster than similar material printed in all capitals." [27] Another study in 1928 showed that "all-capital text was read 11.8 percent slower than lower case, or approximately 38 words per minute slower", [28] and that "nine-tenths of adult readers consider lower case more legible than all capitals". [29]
A 1955 study by Miles Tinker showed that "all-capital text retarded speed of reading from 9.5 to 19.0 percent for the 5 and 10-minute time limits, and 13.9 percent for the whole 20-minute period". [30] Tinker concluded that, "Obviously, all-capital printing slows reading to a marked degree in comparison with Roman lower case." [29]
Tinker provides the following explanations for why all capital printing is more difficult to read:
Text in all capitals covers about 35 percent more printing surface than the same material set in lower case. This would tend to increase the reading time. When this is combined with the difficulty in reading words in all-capital letters as units, the hindrance to rapid reading becomes marked. In the eye-movement study by Tinker and Patterson, the principal difference in oculomotor patterns between lower case and all capitals was the very large increase in number of fixation pauses for reading the all-capital print. [31]
All caps text should be eliminated from most forms of composition, according to Tinker:
Considering the evidence that all-capital printing retards speed of reading to a striking degree in comparison with lower case and is not liked by readers, it would seem wise to eliminate such printing whenever rapid reading and consumer (reader) views are of importance. Examples of this would include any continuous reading material, posters, bus cards, billboards, magazine advertising copy, headings in books, business forms and records, titles of articles, books and book chapters, and newspaper headlines. [32]
Colin Wheildon stated that there is an "apparent consensus" that lower-case text is more legible, but that some editors continue to use all caps in text regardless. In his studies of all caps in headlines, he states that, "Editors who favor capitals claim that they give greater emphasis. Those who prefer lower case claim their preferences gives greater legibility." Wheildon, who informs us that "When a person reads a line of type, the eye recognizes letters by the shapes of their upper halves", asserts that recognizing words in all caps "becomes a task instead of a natural process". [33] His conclusions, based on scientific testing in 1982–1990, are: "Headlines set in capital letters are significantly less legible than those set in lower case." [34]
John Ryder, in the Case for Legibility, stated that "Printing with capital letters can be done sufficiently well to arouse interest and, with short lines, reading at a slowed speed is possible – but in principle too many factors of low legibility are involved." [35]
Other critics are of the opinion that all caps letters in text are often "too tightly packed against each other". [36]
Besides the aforementioned speed of reading, all caps is can be prone to character-based ambiguities.
Namely, the upper-case letters are globally simpler than their lower-case counterpart. For example, they lack ascenders and descenders. Since they are built from fewer positional and building elements (e.g. a smaller grid pertaining to minimalist digital fonts), they are more fragile to small changes.
These variations, generally involuntary but sometimes induced on purpose, are caused by a misinterpretation (the information is transferred) or by a deterioration (the data is lost, in the analysis wording). They can occur horizontally and/or vertically, while misreading (without this extra effort or time), or during a delicate scanning of characters (from a damaged image that needs further contextual text correction).
Depending on the typeface, these similarities accidentally create various duplicates (even quite briefly and without realizing it when reading). E.g. H/A, F/E or I/T by adding a bar; P/R, O/Q, even C/G from similar errors; V/U, D/O, even B/S while rounding the shape; and more deformations implying mixings.
Adding digits in all caps styled texts may multiply these confusions, which is one aim of Leet (intentional pseudo duplicates) and can provide simple means of concealing messages (often numbers).
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.
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 and lettering, a sans-serif, sans serif, gothic, or simply sans letterform is one that does not have extending features called "serifs" at the end of strokes. Sans-serif typefaces tend to have less stroke width variation than serif typefaces. They are often used to convey simplicity and modernity or minimalism. For the purposes of type classification, sans-serif designs are usually divided into these major groups: § Grotesque, § Neo-grotesque, § Geometric, § Humanist, and § Other or mixed.
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.
Capitalization or capitalisation is writing a word with its first letter as a capital letter and the remaining letters in lower case, in writing systems with a case distinction. The term also may refer to the choice of the casing applied to text.
In typography, emphasis is the strengthening of words in a text with a font in a different style from the rest of the text, to highlight them. It is the equivalent of prosody stress in speech.
Gill Sans is a humanist sans-serif typeface designed by Eric Gill and released by the British branch of Monotype from 1928 onwards.
Letter case is the distinction between the letters that are in larger uppercase or capitals and smaller lowercase in the written representation of certain languages. The writing systems that distinguish between the upper- and lowercase have two parallel sets of letters: each in the majuscule set has a counterpart in the minuscule set. Some counterpart letters have the same shape, and differ only in size, but for others the shapes are different. The two case variants are alternative representations of the same letter: they have the same name and pronunciation and are typically treated identically when sorting in alphabetical order.
In typography and handwriting, a descender is the portion of a letter that extends below the baseline of a font.
In typography, small caps are characters typeset with glyphs that resemble uppercase letters but reduced in height and weight close to the surrounding lowercase letters or text figures. This is technically not a case-transformation, but a substitution of glyphs, although the effect is often approximated by case-transformation and scaling. Small caps are used in running text as a form of emphasis that is less dominant than all uppercase text, and as a method of emphasis or distinctiveness for text alongside or instead of italics, or when boldface is inappropriate. For example, the text "Text in small caps" appears as text in small caps in small caps. Small caps can be used to draw attention to the opening phrase or line of a new section of text, or to provide an additional style in a dictionary entry where many parts must be typographically differentiated.
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.
Bembo is a serif typeface created by the British branch of the Monotype Corporation in 1928–1929 and most commonly used for body text. It is a member of the "old-style" of serif fonts, with its regular or roman style based on a design cut around 1495 by Francesco Griffo for Venetian printer Aldus Manutius, sometimes generically called the "Aldine roman". Bembo is named for Manutius's first publication with it, a small 1496 book by the poet and cleric Pietro Bembo. The italic is based on work by Giovanni Antonio Tagliente, a calligrapher who worked as a printer in the 1520s, after the time of Manutius and Griffo.
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. 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.
Sentence spacing concerns how spaces are inserted between sentences in typeset text and is a matter of typographical convention. Since the introduction of movable-type printing in Europe, various sentence spacing conventions have been used in languages with a Latin alphabet. These include a normal word space, a single enlarged space, and two full spaces.
Transport is a sans serif typeface first designed for road signs in the United Kingdom. It was created between 1957 and 1963 by Jock Kinneir and Margaret Calvert as part of their work as designers for the Department of Transport's Anderson and Worboys committees.
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.
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.
Miles Albert Tinker was an American author. He is "an internationally recognized authority on legibility of print" who published the results of some of the most comprehensive studies on the legibility of print ever conducted. According to Jeremy York, Tinker's work, along with his colleague Donald G. Paterson, "was a driving force behind the standardization of the print industry in the United States".
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.
Jason Santa Maria, creative director of Happy Cog Studios, which designs Web sites, detected a basic breach of netiquette. 'Hillary's text is all caps, like shouting,' he said.
