Why does this work so effortlessly? Several factors are at play here. First,
when using different fonts from the same typeface, you are likely going to
have a high degree of visual compatibility without even working for it.
Second, we՚ve chosen the tried-and-true combinations of using a classic
neutral heading typeface and a classic neutral body typeface.
Both Helvetica Neue and Garamond have distinct yet neutral personalities,
and they can weave complex layouts together and around each other
because we՚ve maintained a strict visual hierarchy. Planning rules and
following them, with the right typefaces, can yield great results with a
minimum of effort.
Use Different Point Sizes
We saved one of the simplest principles for last: use different point sizes to
create contrast and distinction.
