Font Pairing Tool

In short Font pairing works on contrast: two typefaces should be clearly different from each other, or clearly the same family, with nothing in between. Two similar sans-serifs look like a mistake rather than a decision, because the reader senses the difference without being able to name it. The reliable combinations pair structural opposites — a serif heading with a sans body, or a geometric display face with a humanist text face — and the pairing is doing its job when you can tell at a glance which text is which without reading it. Two fonts is enough for almost any page and three is the practical maximum; beyond that a page looks assembled rather than designed. Weight and size do more work than a third family would anyway. Two practical constraints that matter more than aesthetics. Every extra family and weight is another file to download, and self-hosting two weights of two families is already a meaningful chunk of a page's budget — variable fonts solve this if you need many weights. And whatever you choose, set a real fallback stack and test with it, because your carefully chosen pairing will not be there for the first paint or when the font request fails.
