Directa Serif Variable is a text type family in one single font file. It explores new possibilities for the original type family released by Outras Fontes some years earlier, which is designed to save space with the highest readability. The variable font is composed of two axes of variation: Weight (100–900) and Italic (0–1). It also contains 18 predefined styles between Thin and Heavy and their respective italics. So now you can adjust the weight of the type by interpolating it in real time using any variable font compatible app. There are hundreds of possibilities between the values of 100 (Thin) and 900 (Heavy). And if you're feeling adventurous, you can also use the Italic axis to interpolate instances between Roman (0) and Italic (1) and see what happens in the middle.
