On typography

For self-publishers, one of the great benefits of personal computers is desktop publishing. Desktop publishing allows self-publishers to set their own type, thus eliminating an expensive, labor-intensive step. (I should know: I used to be a typesetter. Now there's practically no such job.)

Like any tool, desktop publishing can be used correctly or incorrectly. Here are seven rules I've collected in 15 years of setting type-rules that will help you to maximize readability. After all, isn't that why you wrote all those words-so people would read them?

1. Body type should always be a serif typeface, such as Times or Palatino. Serif type has thick-and-thin strokes and little tails on the letters. Sans-serif type, such as Helvetica or Arial, is acceptable for captions or short citations, but studies show it's harder to read.

2. Body type should be justified. That is, it should have a straight margin on the left and right side. Justified type lets the eye establish a rhythm, which makes reading less tiring.

3. Avoid using all capital letters. When reading, the human eye sees the silhouettes of words. When your book is in capital letters the silhouettes are all the same, which slows the reader down. (And in the age of email, using all caps is the same as shouting.)

4. Chances are your computer came with a lot of fancy typefaces. Resist the temptation to use them. The easiest-to-read book will use one type font for body copy and a second for everything else-display type, captions, running heads, short citations, etc. (A font includes bold and italics.)

5. Use initial capital letters, boldface, and italics sparingly. Consult a dictionary or style guide if you're not sure what's appropriate.

6. Think like a typesetter, not like a typist. Use italics instead of underlines, smart quotes and apostrophes (“and,” it’s) instead of straight ("and," it's), dashes instead of hyphens where appropriate. Don't put two spaces after a period. Don't use letter l for number 1.

7. The width of a column of text and the type size are related. Edmund C. Arnold, a renowned editor, used this formula: O=lca x 1.5. The optimum column width (O) is the length of the lowercase alphabet (lca) times 1.5. Type the alphabet in small letters on one line, measure it, and multiply by 1.5 to get the most readable column width for that typeface and size.

Applying these rules will give your books a professional, readable look. This lets the reader concentrate on your ideas.
