The TwoBlock type system consists of four complete typefaces, TwoBlock A, B, C and D, and two related sub-component typefaces, TwoBlock E and F, in which the horizontal and vertical strokes of TwoBlock D are implemented separately. Every typeface in the TwoBlock family has been drawn in nine weights, all of which are designed to interlock precisely in layers.

TwoBlock is a part of MuirMcNeil’s extensive Two Type System. The many subgroups that comprise the Two System have not been designed as independent alphabets but as the framework of an expansive design space in which individual glyphs are configured to collaborate with each other harmoniously.
