Font Pairing by Contrast and Scale: A Method
Most font pairing advice is subjective. Here is a contrast and scale method I use to make pairing decisions repeatable. Font pairing advice usually boils down to pair a serif with a sans-serif and hope for the best. That guidance is it is not a method. It leaves you guessing when a pairing does not work and gives you no way to diagnose why. After years of trial and error, I developed a contrast and scale method that makes pairing decisions repeatable, diagnosable, and defensible to clients. Here is how it works. Define Contrast Along Three Axes When I evaluate a font pairing, I assess contrast along three axes: classification contrast, weight contrast, and texture contrast. Classification contrast is the obvious one, serif versus sans-serif, but also humanist sans versus geometric sans, or transitional serif versus slab serif. Weight contrast means the heading weight and body weight are far enough apart that the hierarchy is visible at a glance. Texture contrast is subtler, it is about how the overall gray value of a paragraph of each font reads. A high-texture font has internal variation in stroke width and letter shape. A low-texture font is more uniform. A good pairing has contrast on at least two of the three axes. If the two fonts are in the same classification, I need weight or texture contrast to carry the hierarchy.
