In typography, small caps (short for "small capitals") are lowercase characters typeset with glyphs that resemble uppercase letters (capitals) 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.
Well-designed small capitals are not simply scaled-down versions of normal capitals; they normally retain the same stroke weight as other letters and have a wider aspect ratio for readability.
Typically, the height of a small capital glyph will be one ex, the same height as most lowercase characters in the font. In fonts with relatively low x-height, however, small caps may be somewhat larger than this. For example, in some Tiro Typeworks fonts, small caps glyphs are 30% larger than x-height, and 70% the height of full capitals. To differentiate between these two alternatives, the x-height form is sometimes called petite caps, preserving the name "small caps" for the larger variant. OpenType fonts can define both forms via the "small caps" and the "petite caps" features. When the support for the petite caps feature is absent from a desktop-publishing program, x-height small caps are often substituted.
Many word processors and text-formatting systems include an option to format text in caps and small caps, which leaves uppercase letters as they are, but converts lowercase letters to small caps. How this is implemented depends on the typesetting system; some can use true small caps glyphs that are included in modern professional font sets; but less complex digital fonts do not have small-caps glyphs, so the typesetting system simply reduces the uppercase letters by a fraction (often 1.5 to 2 points less than the base scale). However, this will make the characters look somewhat out of proportion. A work-around to simulate real small capitals is to use a [clarification needed] version of the small caps generated by such systems, to match well with the normal weights of capitals and lowercase, especially when such small caps are extended about 5% or letter-spaced a half point or a point.
Small caps are often used in sections of text that are unremarkable and thus a run of uppercase capital letters might imply an emphasis that is not intended. For example, the style of some publications, like The New Yorker and The Economist, is to use small caps for acronyms and initialisms longer than three letters—thus "U.S." and "W.H.O." in normal caps but "nato" in small caps.
In printed plays and stage directions, small caps are usually used for the names of characters before their lines.
French and some British publications use small caps to indicate the surname by which someone with a long formal name is to be designated in the rest of a written work. An elementary example is Don Quixote de La Mancha. Similarly, they are used for those languages in which the surname comes first, such as the Romanization Mao Zedong.
In many versions of the Old Testament of the Bible, the word "Lord" is set in small caps. Typically, an ordinary "Lord" corresponds to the use of the word Adonai in the original Hebrew, but the small caps "Lord" corresponds to the use of Yahweh in the original; in some versions the compound "Lord God" represents the Hebrew compound Adonai Yahweh.

In many books, when one part of the book mentions another part of the same book, or mentions the work as a whole, the name is set in small caps (sometimes typesetting small caps after transforming to Title Case), not italics and not roman type within quotation marks. For example, articles in The World Book Encyclopedia refer to the encyclopedia as a whole and to the encyclopedia's other articles in small caps, as in the "Insurance" article's direction, at one point, to "See No-Fault Insurance", "No-Fault Insurance" being another of the encyclopedia's articles.
Research by Margaret M. Smith concluded that the use of small caps was probably popularised by Johann Froben in the early 16th century, who used them extensively from 1516. Froben may have been influenced by Aldus Manutius, who used very small capitals with printing Greek and at the start of lines of italic, copying a style common in manuscripts at the time, and sometimes used these capitals to set headings in his printing; as a result these headings were in all caps, but in capitals from a smaller font than the body text type. The idea caught on in France, where small capitals were used by Simon de Colines, Robert Estienne and Claude Garamond. Johannes Philippus de Lignamine used small caps in the 1470s, but apparently was not copied at the time.
Small capitals are not found in all font designs, as traditionally in printing they were primarily used within the body text of books and so are often not found in fonts that are not intended for this purpose, such as sans-serif types which historically were not preferred for book printing. Fonts in Use reports that Gert Wunderlich's Maxima (1970), for Typoart, was "maybe the first sans serif to feature small caps and optional oldstyle numerals across all weights." (Some caps-only typefaces intended for printing stationery, for instance Copperplate Gothic and Bank Gothic, were intended to be used with smaller sizes serving as small capitals, and had no lower case as a result.)
Italic small capitals were historically rare. Some digital font families, sometimes digitisations of older metal type designs, still only have small caps in the regular or roman style and do not have small caps in bold or italic styles. This is again because small caps were normally only used in body text and cutting bold and italic small caps was thought unnecessary. An isolated early appearance was in the Enschedé type foundry specimen of 1768, which featured a set cut by Joan Michaël Fleischman. (Bold type did not appear until the nineteenth century.) In 1956, Hugh Williamson's textbook Methods of Book Design noted that "one of the most conspicuous defects" of contemporary book faces was that they did not generally feature italic small capitals: "these would certainly be widely used if they were generally available". Exceptions available at the time were Linotype's Pilgrilm, Janson and their release of Monotype Garamond, and from Monotype Romulus. More have appeared in the digital period, such as in Hoefler Text and FF Scala/Scala Sans.
The OpenType font standard provides support for transformations from normal letters to small caps by two feature tags,
c2sc. A font may use the tag
smcp to indicate how to transform lower-case letters to small caps, and the tag
c2sc to indicate how to transform upper-case letters to small caps.
Professional desktop publishing applications supporting genuine small caps include Quark XPress, and Adobe Creative Suite applications.
Most word processing applications, including Microsoft Word and Pages, do not automatically substitute true small caps when working with OpenType fonts that include them, instead generating scaled ones. For these applications it is therefore easier to work with fonts that have true small caps as a completely separate style, similar to bold or italic. Few free and open-source fonts have this feature; an exception is Georg Duffner's EB Garamond, in open beta. LibreOffice Writer started allowing true small caps for OpenType fonts since version 5.3, they can be enabled via a syntax used in the Font Name input box, including font name, a colon, feature tag, an equals sign and feature value, for example,
EB Garamond 12:smcp=1, and version 6.2 added a dialog to switch.
Although small caps are allographs of their full size equivalents (and so not usually "semantically important"), the Unicode standard does define a number of "small capital" characters in the IPA extensions, Phonetic Extensions and Latin Extended-D ranges (0250–02AF, 1D00–1D7F, A720–A7FF). These characters, with official names such as latin letter small capital a, are meant for use in phonetic representations. For example, ʀ represents a uvular trill. They should not normally be used in other contexts (the 'normal' character set should be used with suitable formatting controls as described in the preceding sections).
The following table shows the existing Unicode small capital characters from the ISO basic Latin alphabet as used in IPA:
Since these glyphs come from different code ranges, they may not display the same size and style, because few typefaces supply all of them.
In Unicode standards
The Unicode Consortium has a typographical convention of using small caps for formal Unicode character names in running text. For example, the name of U+0416 Ж is conventionally shown as CYRILLIC CAPITAL LETTER ZHE.

Since the CSS styles the text, and no actual case transformation is applied, readers are still able to copy the normally-capitalized plain text from the web page as rendered by a browser.
CSS3 can specify OpenType small caps (given the 'smcp' feature in the font replaces glyphs with proper small caps glyphs) by using
font-variant-caps: small-caps;, which is the recommended way, or
font-feature-settings: 'smcp';, which is (as of May 2014) the most widely used way. If the font does not have small-cap glyphs, lowercase letters are displayed.
<span style="font-variant-caps: small-caps;">Jane Doe</span>

font-variant-caps: small-caps; is exactly equivalent to
Computer support for petite caps
The OpenType font standard provides support for transformations from normal letters to petite caps by two feature tags,
c2pc. A font may use the tag
pcap to indicate how to transform lower-case letters to petite caps, and the tag
c2pc to indicate how to transform upper-case letters to petite caps.
Cascading Style Sheets
As of September 2018, there is no specific support for petite caps in web pages using the CSS Fonts Module Level 3 by the W3C, but can be specified by using
font-feature-settings: 'pcap';. If the font does not have petite-cap glyphs, lowercase letters are displayed.
