Origami Calculators
Free origami calculators: paper size for any model size, crease count estimator, folding angle dimensions, and sheet ratio guides.
Origami Paper Size Calculator
Estimate the starting paper size needed to fold an origami model of a specific finished size. Adjust for model complexity and folding style.
Paper Folds to Thickness Calculator
Calculate the theoretical thickness of paper after N folds. Doubling formula 2^n shows why no one folds paper more than 7-8 times by hand.
Origami Paper GSM to Thickness Calculator
Convert paper GSM to thickness in mm or mils for origami. Enter weight and paper type to get caliper, suitability, and recommended fold count for projects.
Origami Square from Rectangle Calculator
Calculate the largest square from a rectangular sheet, plus how many same-size squares one sheet yields. Turn printer paper into origami without waste.
Modular Origami Unit Count Calculator
Calculate paper units for Sonobe, PHiZZ, Kusudama, and other modular origami polyhedra. Returns unit count, sheet requirements, and assembly difficulty rating.
Origami Crease Pattern Fold Count Calculator
Estimate crease count, valley folds, and mountain folds in an origami model from complexity and base type — bird, frog, waterbomb, or preliminary.
Origami Paper Size Calculator
Calculate the ideal paper size for any origami model based on desired finished size. Covers square, rectangle, and A-series paper.
Origami Tessellation Grid Calculator
Calculate grid divisions, minimum paper size, and pre-crease count for origami tessellations. Covers triangle, square, and hex grids for flat and 3D folds.
Wet Folding Paper Weight Calculator
Calculate ideal paper weight in GSM and water-to-paper ratio for wet folding origami. Covers animal and sculptural models with drying time guidance.
