Static fonts have a separate file for every style (light, regular, bold condensed, thin expanded, etc.). Variable fonts have one file that includes every style, but don't worry! You will still see separate styles on the font selection menu, just like any other typeface.
This technology offers several advantages. The first is that the overall weight of the font family is significantly reduced by having one file instead of multiple files. The second advantage is that it provides users with more choices while designing, as it offers significantly more style options and permutations. Thirdly, it allows type designers to have greater control, creative freedom, and room for experimentation.
We believe that variable fonts are the future, which is why all our fonts are created this way.
