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
