Line spacing refers to the amount of space between individual lines contained within a paragraph. The amount of space above and below a paragraph is called paragraph spacing.
Different types of documents often require specific line and paragraph spacing. This is easily accomplished in most modern word processing applications by changing the style settings. These settings can be changed to encompass the entire document, or the line spacing in specific areas of the document can be changed by selecting the area of text to change. Line spacing and paragraph spacing can generally be changed in small increments, giving the user control over the appearance of a document.
