What term is used for the measure of space between lines of text?

The term that refers to the measure of space between lines of text is "leading." This spacing plays a crucial role in typography and design, as it influences the readability and overall look of the text. By adjusting the leading, designers can improve the flow of text and create a more visually appealing layout. A larger leading value can create a more spacious and airy feel, making the text easier to read in different contexts, such as websites, print media, or animation captions.

In contrast, alignment pertains to the positioning of text in relation to its surrounding elements, while kerning refers specifically to the adjustment of spacing between individual character pairs to achieve a balanced appearance. Tracking, similar to leading, involves the adjustment of spacing within a block of text, but it affects the overall letter spacing rather than the spacing between lines. Understanding these terms is essential for effective text design in Adobe Animate and other graphic design software.
