Operating system fonts

Avoid using the core operating system fonts in printed documents.

On Windows, that includes Arial, Calibri, Cambria, Candara, Comic Sans, Constantia, Courier, Georgia, Helvetica, any flavor of Lucida, Palatino, Trebuchet, and Verdana. On the Mac, that includes Arial, Courier, Helvetica, Palatino, Skia, and Verdana. Subject to a few exceptions, you should also avoid Times New Roman.

Operating system typefaces have three problems:

  1. They’re overexposed. The fact that they’re included with the operating system for free means that people who are lazy and cheap tend to use them. You don’t want to be lumped in with those people.
  2. They’re not very good. This is less a problem on the Mac. But certain typefaces included with Windows are among the most god-awful on the planet. I don’t want to name names, but my least favorite rhymes with Barial.
  3. They’re optimized for screen display, not printing. The Mac and Windows system fonts have been meticulously engineered to look good on screen (for instance, website text). But often, that means that subtle design details have been sanded off, and the typeface looks clunky on the printed page (e.g. Georgia).

Corollary to #3: the operating system fonts are usually just fine for on-screen use, such as PowerPoint presentations or websites. But stay away from Comic Sans for any purpose.
