In Ribbon Arch, what size is the gold archwire used?

Explanation:
Ribbon Arch relies on a slender rectangular archwire that can form a broad, gentle arch with low friction between components. The 11x20 gold wire is the standard choice because its rectangular cross-section provides the right balance of flexibility and contour control for this technique, allowing the arch to be shaped to the ribbon form and to deliver precise, light forces. The other sizes describe different cross-sections that do not match the specific requirements of Ribbon Arch, and thus are not used in this context.
