Sinkin Sans
A clean grotesque released free under the Apache 2.0 licence, spanning all nine CSS numerical weights with matching italics and a narrow companion family.
About
Sinkin Sans distinguishes itself through small notches cut into vertical strokes at their intersections, sharpening right angles and improving definition in complex characters. The family was created as K-Type's own site font and released as 18 free styles covering weights 100 to 900, each with an italic. Sinkin Sans Narrow provides a sensitively condensed alternative for space-constrained settings.
Classification
A clean sans-serif with grotesque characteristics, designed with subtle notched intersections at stroke junctions. The proportions are generous and the overall character is neutral and readable.
