THE PROCESS OF CREATING NEW FONT STYLES BY BLENDING BETWEEN EXISTING ONES.
In type design, interpolation is how fonts smoothly transition between styles.
Start with a light and a bold version of a typeface, and interpolation fills everything in between—regular, medium, semibold—all without drawing each one by hand.
This trick has been around for decades, but modern software takes it to another level.
They don’t just interpolate weight; they can also shift width, slant, and more, all in real-time.
It’s why a single font file can now do the work of dozens. Pretty neat, right?
