One Typeface Is Rarely the Right Answer
A brand system built entirely on one display typeface can look striking on a poster and fall apart the moment it hits a paragraph of body text or a small UI label. Display faces are often drawn for impact at large sizes, with details that disappear or turn muddy once the type gets small.
Most working systems pair two typefaces with clearly different jobs: one built for personality at large sizes, one built for legibility at small sizes. The trick is choosing a pairing that shares some underlying quality — similar contrast, similar x-height, similar mood — so the two feel related rather than randomly stitched together.
A simple test: set a full paragraph of real body copy in the display typeface at 14px. If it’s uncomfortable to read for more than two sentences, that’s the signal a second typeface is needed, not a smaller decision to just make it fit.
