Which term describes the adjustment of horizontal spacing between letters?

The term that describes the adjustment of horizontal spacing between letters is kerning. Kerning refers specifically to the space between individual characters in a word, and it allows for a more visually appealing and readable design. By adjusting the distances between select pairs of letters, designers can fix awkward spacing or create a more cohesive look in typography.

For example, certain letter combinations may appear too far apart or too close together, and kerning helps to fine-tune that spacing for optimal aesthetics. This is particularly important in logo design or any text that requires precision for branding purposes. Understanding and applying kerning effectively can greatly enhance the visual flow and overall impact of text in a design.

Leading, on the other hand, pertains to the vertical spacing between lines of text, while tracking involves the uniform adjustment of spacing across an entire block of text, affecting all letters equally. Alignment relates to the distribution of text within a given space, without impacting the spacing between individual letters. Each of these terms addresses different aspects of typography and layout, emphasizing the importance of precise spacing in interactive design.
