Crease Pattern ScalingOrigami & Folding
Convert diagram sizes, grid measurements, and template grids to actual physical paper dimensions for advanced origami models and tessellations.
For advanced tessellations or geometric crease patterns, the size of each grid partition determines folding ease.
Origami is the intersection of mathematical geometry and material engineering. Optimal folds are highly dependent on fiber lengths and wood grain direction.
