Blueprint vs Monospace

ブループリント / モノスペース

Blueprint comes from Technical Expression and Monospace from Type Classification. Both are read here as style. They are reached for with some of the same intent, which is where they get confused.

Blueprint

Instead of a finished object it shows the lines of the thinking behind it, communicating structure and possibility.

Monospace

Fixed-width letters born from the typewriter's mechanism, settled as the voice of work-in-progress: drafts, forms and code.

CautionNo fake drawings as decoration. Bind everything to actual structure and thought.Long Japanese passages set monospaced space the kana too evenly, word clusters fall apart, and readability is traded away for atmosphere.
