Origami Scaling & SizingOrigami & Folding
Calculate required starting square paper size to achieve a specific target finished 3D model size for standard designs (e.g., Crane, Box, Kawasaki Rose, Dragon).
Origami is the intersection of mathematical geometry and material engineering. Optimal folds are highly dependent on fiber lengths and wood grain direction.
Simple fold. Wingspan is approx. 50% of starting square diagonal.
