TWO READINGS OF FORMAT
Sequence.
Orientation.
Bosshard presents a systematic run of regular rectangles from the square to 1:3. The referenced Poussin chart presents a separate set of 10 horizontal and 7 vertical frame formats. Norma keeps both sources distinct.
Sources: Bosshard rectangle values are transcribed from the supplied plate. Poussin’s five-figure alphabet and the 10 horizontal / 7 vertical format system are documented by nicolas-poussin.com. Construction guides appear only where the underlying square, φ, √2, √3, or rational modular construction is supported.
Seventeen chart formats
Ten horizontal and seven vertical formats are reproduced in the order and width/height values shown by the supplied chart.
