Tracking

Adjusting the overall spacing of a group of letters is called tracking or letterspacing. By expanding the tracking across a word, line, or entire block of text, the designer can create a more airy, open field. In blocks of text, tracking is usually applied in small increments, creating a subtle effect not noticeable to the casual reader. Occasionally, a single word or phrase is tracked for emphasis, especially when CAPS or small caps are used within a line. Negative tracking, rarely desirable in text sizes, can be used sparingly to help bring up a short line of text. White type on a black background is considered more legible when it is tracked.

Line Spacing

The distance from the baseline of one line of type to another is called line spacing. It is also called leading, in reference to the strips of lead used to separate lines of metal type. The default setting in most layout and imaging software is 120 percent of the type size. Thus 10-pt type is set with 12 pts of line spacing. Designers play with line spacing in order to create distinctive typographic arrangements. Reducing the standard distance creates a denser typographic color, while risking collisions between ascenders and descenders. Expanding the line spacing creates a lighter, more open text block. As leading increases, lines of type become independent graphic elements rather than parts of an overall visual shape and texture.

Alignment

Choosing to align text in justified, centered, or ragged columns is a fundamental typographic act. Each mode of alignment carries unique formal qualities, cultural associations, and aesthetic risks.
