Unit 8 Fourteen Typography RulesRule 1 Rules must first be understood before they can be broken.Once you have a good foundation of these rules, you can freely journey into unconventional terrain.Rule 2 Be mindful not to use too many different typefaces at any one time. The main reason for using more than one typeface is to create emphasis or to separate one part of the text from another. When too many different typefaces are used, the reader is unable to determine what is and what is not important.Rule 5 For text type, use sizes that, according to legibility studies, prove most readable. These sizes generally range from 8 to 12 points for text that is read from an average distance of 12 to 14 inches. Be sure to remember that sizes (based on the x-height of letters) appear different from one typeface to another.Rule 6 Use text types of book weight. Avoid typefaces appearing too heavy or too light. Text typefaces that are too light cannot easily be distinguished from their backgrounds. In typefaces that are too heavy, counter forms diminish in size, making them less legible.Rule 7 Use typefaces of medium width. Avoid typefaces that appear extremely wide or narrow in width. Rather than distorting text or stretching or squeezing the text width, use type families that include condensed and extended faces that fall within accepted proportional norms.Rule 8 For text type, use consistent letter and word spacing to produce an even, uninterrupted texture. Letters should flow gracefully and naturally into words, and words into lines. This means that word spacing should increase proportionally as letter spacing increases.Rule 9 Use appropriate line lengths. Lines that are too short or too long disrupt the reading process. As the eye travels along overly long lines, negotiating the next line becomes difficult. Reading overly short lines creates choppy eye movements that tire and annoy the reader. When working with text type, a maximum of about 70 characters (10 to 12 words) per
