In today's world, Thin space has become a topic of great relevance and interest among a wide public. From its origins to its impact on contemporary society, Thin space has captured the attention of academics, professionals and enthusiasts alike. With a rich and complex history, Thin space has evolved over the years, influencing different aspects of everyday life and playing a crucial role in numerous areas. In this article, we will thoroughly explore the importance of Thin space and its influence in various fields, from culture to economics, politics and technology.
In typography, a thin space is a space character whose width is usually 1⁄5 or 1⁄6 of an em. It is used to add a narrow space, such as between nested quotation marks or to separate glyphs that interfere with one another. It is not as narrow as the hair space. It is also used in the International System of Units and in many countries as a thousands separator when writing numbers in groups of three digits, in order to facilitate reading.
In Unicode, thin space is encoded at U+2009 THIN SPACE ( ,  ). Some text editors, such as IntelliJ IDEA and Android Studio, will display the character as its suggested abbreviation of "THSP
". Unicode's U+202F ] is a non-breaking space with a width similar to that of the thin space.
In LaTeX and Plain TeX, \thinspace
produces a narrow, non-breaking space. Inside and outside of math formulae in LaTeX, \,
also produces a narrow, non-breaking space.
In all versions of LibreOffice and in some of Microsoft Word, the special characters and symbols dialog (often available via Insert > Symbol or Insert > Special Characters), has both the thin space and the narrow no-break space available for point-and-click insertion. In LibreOffice's Symbol dialog, there is an easy-to-find box field to narrow the searching; in Word's Symbol dialog, under font = "(normal text)", the characters are found in subset = "General Punctuation", Unicode character 2009 and nearby. Other word processing programs and in many Linux configurations, have ways of producing a thin space using keyboard shortcuts.
