Variable, Real Fonts: A Glimpse into the Future, plan "B"

Have you encountered the .rwf font format yet? RealWrittenFont. It's an advanced evolution of vector fonts. Unlike the classic "old-school" fonts, which appear identical on every device and every render as long as the size is the same, .rwf introduces a twist that mimics the authenticity of human handwriting.

Think about it—our handwriting has unique characteristics that define us, but no one writes the exact same letter twice. Tiny variations are always present, even in our own writing. This new .rwf format embraces this reality. It doesn’t just store a single vector design for each letter but also captures its possible variations and patterns.

Imagine the crossbar of an uppercase "I." In traditional fonts, its position is fixed—say, always between 48% and 52% of the total height. But .rwf takes a more dynamic approach. It defines the position as being between 40% and 60%, with a width varying from 3 to 10 units. This is, of course, a simplified explanation. The font maintains stylistic consistency and continuity rules that make it recognizable while introducing subtle, lifelike variations.

The "Seed" Solution: Preventing Chaos

However, there’s a challenge here: if every render allows completely free variations within the defined boundaries, no two renderings would look the same. Worse, refreshing a webpage could make the text “dance,” as letters shift ever so slightly each time.

To prevent this chaos, .rwf fonts include a "seed" value. This value, defaulting to 0, ensures consistency across renders while still allowing variability within individual characters. Developers can set the seed to any numeric value, enabling predictable rendering for all users on all devices. Yet even with this consistency, subtle diversity remains—two consecutive identical letters in a word will never appear exactly the same.

The Future of Real Fonts

As of now, I haven’t found any readily available .rwf typefaces, but this innovative technology feels like a game-changer. With its potential to add a layer of authenticity and personality to digital text, it’s only a matter of time before we start seeing .rwf fonts pop up in web design, apps, and beyond.

So, keep your eyes on this space, developers—variable, real fonts might just redefine how we think about typography in the digital age.
