Paper Type Guide
| Paper Type | Weight | Best For | Notes |
|---|---|---|---|
| Kami (origami paper) | 60–80 gsm | Most standard models | Colored one side; crisp folds |
| Copy / Printer paper | 75–90 gsm | Practice, flat models | Not ideal for 3D or wet-folding |
| Washi | 40–60 gsm | Complex models, wet-folding | Strong but soft; excellent texture |
| Foil-backed paper | 50–70 gsm | Roses, insects, detailed work | Holds creases perfectly; less forgiving |
| Tissue foil | 30–50 gsm | Advanced insects, wet-folding | Very thin; excellent for complex models |
Square vs Rectangle
Most origami models require a square sheet. A few classic designs — like the traditional paper airplane, hat, and cup — use rectangles. When converting a rectangle to a square, fold one corner to the adjacent edge and cut off the excess strip.
The standard kami origami sheet is 6"×6" (15cm×15cm), which works well for most beginner and intermediate models. For complex models with many layers (roses, modular polyhedra), use larger sheets — 10" or more — until you're comfortable with the folding sequence.
