In typography, leading ( LED-ing) refers to the distance between the baselines of successive lines of type. The term originated in the days of hand-typesetting, when thin strips of lead were inserted into the forms to increase the vertical distance between lines of type. The term is still used in modern page-layout software such as QuarkXPress and Adobe InDesign.
