Office Fonts are always the best choice for non-design applications, such as Word, Excel, PowerPoint, Pages, Numbers, or Keynote.
If you’re a designer, you’ll use traditional Multipurpose fonts for design work, in programs such as Illustrator, InDesign, or Photoshop. If you’re preparing templates for non-designers to use, such as correspondence blanks or presentation decks, use the same Office Fonts that your clients will ultimately license. The same applies to mail merge templates for generating personalized content: make sure that both you and your lettershop have each licensed the same Office Fonts.
Office Fonts differ from Multipurpose fonts in subtle but important ways. In order to improve their appearance on both low resolution screens and business printers, many Office Fonts have a different size on the body, a slightly larger lowercase, and a more generous fit. It’s therefore important to build your templates from the outset using Office Fonts, instead of designing them with Multipurpose fonts and changing the palette later.
Both Multipurpose and Office Fonts can be installed simultaneously, each appearing as its own family in the font menu (e.g. “Gotham” and “Gotham Office.”)
