About TenPoint

MuirMcNeil TenPoint is a modular type system constructed from repetitions of a single cell within a fixed geometric grid. It is an attempt to locate typographic objects at the lowest limit of their function as vehicles of language and to codify their visual arrangements.

There are seven sizes of TenPoint: 01, 02, 03, 04, 05, 06 and 08; the numerical index referring to the cell count repetitions which define the overall body height of each size.
In settings made with the smallest type sizes, bodies of words are given solid form but the contours of individual glyphs are difficult or impossible to recognise discretely. At such low resolutions, the text becomes distilled to a textile, an abstracted linear weave which discloses little more information than the rhythm of its own spatial organisation.

As sizes and resolutions increase progressively, the contours of individual letters and their sequences, as words, begin to become more complex, more defined and thus more identifiable. Normal service is resumed as rudimentary levels of readability begin to be achieved.
