singlespace

Singlespace is a typographic setting in which the vertical distance between the baselines of successive lines is minimized to a single leading. In modern word processing, single spacing is typically implemented as 1.0 line height, with the exact rendering depending on font metrics and software defaults. Double spacing, by contrast, uses about 2.0 leading, creating a blank line between lines of text. Some styles use intermediate values such as 1.15 or 1.5 for improved readability.

Usage of singlespace varies by context. It is common for informal writing, notes, web content, and drafts where compact text is desired or page count matters. In academic and professional publishing, many style guides and journals prefer larger leading—often double spacing—to facilitate reviewing, commenting, and editing. Some guidelines permit 1.15 or 1.5 spacing for readability while still reducing page length.

Variations and related considerations. Leading is distinct from spacing after sentences; traditional conventions about one space after a period are separate from line spacing and are a matter of typography and style choice in digital typesetting. In practice, the choice between singlespace and double space reflects disciplinary norms, publication requirements, and readability goals. Modern editors often balance compactness with legibility, selecting a line height appropriate to the document’s purpose and audience.
