Open source – Variable Fonts

Variable Fonts v0.2

A simple resource for finding and trying variable fonts

⚠️ Notice: As a showcase of variable fonts, this site requires a web browser that supports OpenType font variation technology. It looks like your browser doesn’t, so please consider upgrading to one that does (the latest versions of Chrome work well, even on older operating systems). Otherwise, the font samples below will only appear as static fonts.

Open-source fonts can typically be used, modified, and distributed free of charge under very permissive terms. Note that there are different open-source licenses with different terms of use. As always, check each font’s license for details.

​Amstelvar is an exercise in variable weight, contrast, and proportions. Positive and negative forms can be manipulated as separate axes, as well as a large array of other variables. It is an experimental work in progress so can produce unusual results.
