The new variable font technology introduced by Adobe, Apple, Google, Microsoft, and others represents a significant change in how typography can be composed and delivered, breaking many of the assumptions about type that have been standard since Gutenberg. While the ideas behind variable fonts aren’t new, the current landscape of responsive design and digital technology makes them more relevant than ever before. Because this technology is so new – with some aspects still in the process of being defined – there are many questions about how it works, what it can or can’t do, and even why it exists. This presentation will discuss the technical and design-related benefits of variable fonts while demonstrating some of their potential applications in the real world.
