In typography, what is the term for the space between lines of text?

The term for the space between lines of text is known as leading. This concept originated from the days of metal type, where strips of lead were used to separate lines of type. Proper leading is essential because it can significantly affect the readability and overall aesthetics of the text. Adjusting the leading can help improve the visual flow and ensure that the lines of text are neither too cramped nor too far apart.

Kerning, on the other hand, refers specifically to the adjustment of space between individual characters to create a more visually appealing arrangement. Tracking involves the spacing adjustment for groups of characters across a whole word or sentence. Justification refers to the alignment of text within a design, ensuring that it aligns evenly along both the left and right margins. Understanding these distinctions is crucial for effective typography in graphic design.
