Bold and italic

The first rule of bold and italic fonts is to use them as little as possible. They are tools for emphasis. But if everything is emphasized, then nothing is emphasized.

Some lawyers are fond of running whole paragraphs in bold type when they feel strongly about the point they’re making. Don’t be one of them. Aside from wearing down the surface of their readers’ retinas, this gives them nowhere to go when they want to emphasize a word. Though some resort to underlining large segments of text or using a lot of bold italic, these are both bad ideas.

If you’re using a serif font (like Times, New Century Schoolbook, or Garamond) use italic if you’re looking for gentle emphasis, or bold if you’re looking for heavy emphasis.

If you’re using a sans serif font (like Arial, Helvetica, or Futura) use bold type for emphasis. It’s not worth italicizing sans serif fonts—unlike serif fonts, which look quite different when italicized, sans serif italic fonts merely have a gentle slant that doesn’t stand out on the page.
