A common time to investigate matching two typefaces together is when choosing a subhead to compliment body text. The idea is to find a typeface that stands out from the body text, creating hierarchy. This makes the subhead easier to find and the text easier to scan by the viewer. Usually, a heavier san serif or slab serif is chosen to go with a serif. Below are a few examples.
To further distinguish between the subhead and the body text, try using all caps or increasing tracking. Adding some negative before or after the subhead also helps set it apart. You know what I always say: embrace negative space.
You can also try some less traditional things. Below I’ve used a lighter weight of the type, but at a larger point size.
There are many other ways to add emphasis to subheads from hanging the subhead outside of the margin to using color. But it all starts with choosing two typefaces that work well with each other.
