Variable fonts guide

Variable fonts are an evolution of the OpenType font specification that enables many different variations of a typeface to be incorporated into a single file, rather than having a separate font file for every width, weight, or style. They let you access all the variations contained in a given font file via CSS and a single @font-face reference. This article will give you all you need to know to get you started using variable fonts.

User Interfaces for Variable Fonts

The tools we design with have a unique effect on the way we work, constraining and empowering us while we explore, examine and create. Variable fonts give us a new, wide open typographic space with which to work. Instead of prescribing value to individual UI elements in a vacuum, we should take a hybrid and calculated approach to variable font interfaces. How do we structure our design tools to adapt to the new advantages variable fonts provide us with?

One File, Many Options: Using Variable Fonts on the Web

Font weights can be far more than just bold and normal—most professionally designed typefaces are available in variants ranging from a thin hairline ultralight to a black extra-heavy bold. To make use of all those weights, we would need a separate file for each. While a design is unlikely to need every font-weight, a wider variety than bold and normal adds visual hierarchy and interest to a page.

Amstelvar Font Breakdown

Amstelvar also contains a “Width” axis, that reduces the transparent (white) shapes and spaces of the letters only, leaving the opaque (black) to the variations of the weight axis alone. Between these two, what I call “single parametric axes,” the “normal” weights and widths of a font family are found, along with the grades, which are different weights on the same metrics. This is currently a single-pole axis, i.e. from the default font, it only gets narrower.
