The
Containment
Rule.
The silver ratio (1 + √2 ≈ 2.414) governs how space is contained — the relationship between an interior and its boundary. ISO paper (A4, A3, A2) is built on the silver ratio: fold it in half and another silver rectangle emerges. Japan's aesthetic of ma — negative space as presence — follows silver proportions.
The mathematics at work.
What the containment means.
How we apply it.
The Containment Rule tells us where to stop. Margins, safe zones, white space, and boundary definitions follow the silver ratio. The contained form feels protected. The proportional boundary creates the sense that the design knows its own edges.
