Gotham is our primary font and is used for headlines, subheads and body copy (if minimal text). On the web, we use only Gotham.
Constantia is our preferred secondary font for body copy in print. If this font is not available, Book Antiqua can be used in substitution.
KEEP IT SIMPLE
Use as few different font sizes as possible (usually around three).
Break up the layout with pull quotes, statistics and graphics.
Don't use too many headlines.
