How to Use This Calculator

Select the model type (1–6) for common polyhedra such as Sonobe cube, octahedron, icosahedron, or kusudama — or choose 7 for a custom unit count.
Enter the side length of each square unit in centimeters (e.g., 7.5 cm is a common unit size).
Set the extra percentage for practice and mistakes — 10% is a good default for intermediate folders.
If using type 7, enter your custom total unit count in the custom field.
Read the total units needed and the total sheets to prepare including the practice allowance.
Use the suggested colors and units per color outputs to plan a visually balanced color scheme.
