TypeRoof: A Hands-on Demo of Tools for Variable and Parametric Fonts

Parametric fonts come with a vast number of variable axes — far too many for sliders to remain a sensible primary UI. TypeRoof, a free/libre open-source toolkit running entirely in the browser, tackles this head-on: it explores new ways to navigate, organize, and control high-dimensional design spaces, from proofing and testing to typesetting, layout, and animation.

In this interactive demo session, led by TypeRoof’s principal architect, we’ll explore the tool live: experimenting with new ways to navigate complex design spaces — beyond the slider — and looking at how these approaches open up possibilities for typesetting, layout, and animation. Bring a laptop with a browser — and your own fonts — and you can follow along hands-on — or simply watch a guided walkthrough as the discussion unfolds.

Whether you’re a type designer, typographer, or developer, you’ll leave with a practical sense of what TypeRoof can do today, where it’s headed — and how you can contribute, especially as we expand support for scripts beyond the Latin alphabet.
