What does 'Leading' refer to in typography?

Leading in typography specifically refers to the vertical space between lines of typeset text. This measurement is crucial for readability and overall aesthetic in design, as it affects how closely or far apart lines of text appear from one another. Proper leading can enhance the flow of text, prevent crowding, and improve legibility, particularly in longer passages.

The size of the space between lines can influence the reader’s ability to follow text smoothly, impacting the overall impression and effectiveness of the print or digital media. If the leading is too tight, lines may crowd together, leading to confusion, while excessive leading can create disjointed text that makes reading laborious.

Understanding leading helps designers make informed choices about spacing in their layouts to create visually appealing and reader-friendly designs.
