Tim Brown:
Just minutes ago, at the ATypI conference in Warsaw, the world was introduced to a new kind of font: a variable font. Jointly developed by Apple, Google, Microsoft, and Adobe, a variable font is, as John Hudson put it, “a single font file that behaves like multiple fonts”. Imagine a single font file gaining an infinite flexibility of weight, width, and other attributes without also gaining file size — and imagine what this means for design.
Mind blown. As with all new cool things on the web, it will be a long path until we can actually use these variable fonts on the web. But it will be a awesome for sure: Imagine beautiful typography combined with fast page loads.
