In typography, small caps (short for small capitals) are grapheme typeset with that resemble uppercase letters but reduced in height and weight close to the surrounding lowercase letters or text figures. 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 x-height, 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 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 ; but less complex 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 bolder 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.
The initialisms , , , and are sometimes typeset in small caps.
In printed plays small caps are used for stage directions and the names of characters before their lines.
Some publications use small caps to indicate surnames. An elementary example is . In the 21st century, the practice is gaining traction in scientific publications.
In many versions of the Old Testament of the Bible, the word "Lord" is set in small caps. (2025). 9780805428360, Holman Bible Publishers. ISBN 9780805428360 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 zoological and botanical nomenclature, the small caps are occasionally used for genera and families.
In computational complexity theory, a sub-field of computer science, the formal names of algorithmic problems, e.g. MᴀxSAT, are sometimes set in small caps.
Linguists use small caps to analyze the morphology and tag (gloss) the parts of speech in a sentence; e.g.,
Linguists also use small caps to refer to the keywords in for particular languages or dialects; e.g. the fleece and trap vowels in English.
The Bluebook prescribes small caps for some titles and names in United States legal citations. The practice precedes World War I, with Harvard Law Review using it while referring to itself. By 1915, small caps were used for all titles of journals and books.
In many books, mention of another part of the same book or mentions the work as a whole will be set in small caps. 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.
Among Romance languages, as an orthographic tradition, only the French language and render Roman numerals in small caps to denote centuries, e.g. xviii siècle and siglo xviii for "18th century"; the numerals are cardinally postpositive in Spanish alone.

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 rarer than roman small caps. Some digital font families, sometimes digitisations of older metal type designs, still only have small caps in 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, (1993). 9789070386580, Stichting Museum Enschedé, the Enschedé Font Foundry, Uitgeverij De Buitenkant. ISBN 9789070386580 and in 1837 Thomas Adams commented that in the United States "small capitals are in general only cast to roman fonts" but that "some founders in England cast italic small capitals to most, if not the whole of their fonts." (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 Eric Gill, 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.
Desktop publishing applications, as well as web browsers, can use these features to display petite caps. However, only a few currently do so. LibreOffice can use the method.
Most word processing applications, including Microsoft Word and Apple 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.
The Unicode petite-capital characters are found in the IPA extensions, Phonetic Extensions, Latin Extended-D and other blocks. These characters are intended for use in notation where they are semantically distinct – that is, for cases where they are not allographs. For example, petite capital represents a uvular trill in IPA, and a voiced uvular plosive; capital and have no defined meaning in IPA, but are commonly used as wildcards for 'Sonorant' and 'Semivowel'. Thus using formatting to replicate would not be appropriate in phonetic notation, because if the formatting were lost, data would be lost and the text would change in meaning.
The petite-capital characters defined by Unicode for letters of the basic Latin alphabet are as follows. Shaded cells mark petite capitals that are not very distinct from minuscules in roman typeface, but they may be distinct in italic typeface, as is used in some phonetic notation.
| ᴢ | ||||||
| 𐞄 ! | ᶰ ! | 𐞪 ! | ᶸ ! | 𐞲 ! | ||
| ! | ◌ᷡ ! | ◌ᷢ ! | !|| | | ! |
* Superscript versions of petite-capital ᴀ, ᴅ, ᴇ and ᴘ have been provisionally assigned for inclusion in a future version of the Unicode Standard.
** Although the overscript (combining superscript) characters are identified as 'small capitals' in Unicode, there are no corresponding capital overscript characters that they contrast with.
Additionally, a few less-common Latin characters, several Greek alphabet characters, and a single Cyrillic character used in Latin-based phonetic notation also have petite capitals encoded:
| Extended Latin | |||||||||||||||||||||||||
| 𝼂 | ᴣ | ||||||||||||||||||||||||
| Greek | |||||||||||
| ꭥ | |||||||||||
There is little call for small caps in Cyrillic, as there would be little graphic difference between small caps and lowercase. However, Unicode does provide for one small cap Cyrillic letter for use in the Uralic Phonetic Alphabet (UPA), where small caps and lowercase are distinct in italic typeface
