Word spacing

This article is about the typographic concept; for the practice of writing with spaces between words, see Interword separation

Word spacing in typography refers to the size of the space between words. It should be distinguished from letter-spacing (the spacing between the letters within each word) and sentence spacing (the spacing between sentences). Typographers may modify the spacing of letters or words in a body of type to aid readability and copy fit, or for aesthetic effect. In web browsers and standardized digital typography the word spacing is controlled by the CSS1 word-spacing property.
