Which term describes the space between letters specifically in typography?

The correct term for the space between letters specifically in typography is kerning. Kerning refers to the adjustment of the spacing between individual letter pairs to achieve a visually pleasing result. It helps ensure that the letters are spaced evenly and that the overall appearance of the text is balanced. Good kerning can significantly improve the readability of text and enhance the aesthetic quality of typography.

Tracking, while related, refers to the uniform spacing between all characters in a block of text rather than the space between two specific letters. Leading pertains to the vertical space between lines of text, and whitespace generally refers to the areas in a design that do not contain text or images, allowing for a clearer layout. Understanding these distinctions is crucial for effective typographic design.
