SIS F2

The SIS F2 paper size establishes dimensions of 479 mm x 677 mm, enclosing around 0.32 square meters. Falling between the rarely used SIS F1 format and ISO B1, it represents one of Sweden's generally unsuccessful 20th century attempts to expand size options.

Lacking broad recognition, the niche SIS F2 does not tend to have widely used alternate name variants. But in certain Swedish contexts, references as “F två” (F two) occasionally arise informally.

Conceivable applications could include large tables, architectural plans, academic posters, and banner displays where SIS F1 is unwieldy. But everyday practical use is nearly nonexistent for unfamiliar SIS F2.

The SIS F2 emerged from Sweden's early 1900s endeavor to systematically interpolate granular sizes amidst ISO's prevailing options. The vision was enabling subtle scaling of contents across formats. But failure loomed amidst economic obstacles, lack of global standardization, and resistance to shifting norms. So today SIS F2 remains an obsolete relic of ambition dashed against infrastructure inertia, its backstory more warning than inspiration.
