What is the term for modifying the space between individual pairs of letters?

The term for modifying the space between individual pairs of letters is known as kerning. This practice focuses specifically on the adjustment of space between two particular letters to improve appearance and readability of the text. Each pair of letters can present unique challenges in terms of how they look together; kerning allows designers to create a visually balanced and aesthetically pleasing arrangement of characters.

Other terms related to letter spacing are distinct from kerning. For instance, letter spacing refers to the overall space between all letters in a text, while tracking pertains to uniform spacing adjustments across a range of characters. Leading, on the other hand, is the vertical space between lines of text. Understanding these differences helps in applying the correct typographical adjustments to achieve the desired visual effect in digital video and print design.
