Principia’s typographical standards have been developed to offer maximum flexbility, while maintaining a consistent aesthetic and visual language. There is one set of standard fonts for Macintosh users and one for PC users.

Adobe Garamond Pro and Times New Roman are classic serif fonts that bring a level of sophistication and readability to printed communications. They should be used for body copy.

Helvetica Neue and Arial are clean, sans serif fonts, embraced for their timelessness and dynamic flexibility. These should be used primarily for headlines and pull-quotes.
