How to Use This Calculator
- Enter the side length of your square paper in centimeters.
- Set the size of one tessellation repeat unit (molecule) in centimeters — measure a practice molecule if possible.
- Enter the pleat depth ratio: shallow pleats are ~0.3, medium ~0.5, deep or complex molecules ~1.0 or more.
- Set the border margin in centimeters to leave unfolded space around the edges for finishing.
- Read the number of repeats per axis and total molecules to know how many pattern units will fit.
- Use the minimum paper size output to check whether your paper is large enough for the desired grid.
How the result changes with Paper size (cm)
| Paper size (cm) | Repeats per axis | Total molecules |
|---|---|---|
| 21 | 4 | 16 |
| 71 | 15 | 225 |
| 130 | 28 | 784 |
| 180 | 39 | 1,521 |
What each input means
- Paper size (cm)
- Side length of the square paper in centimeters.
- Molecule size (cm)
- Size of one tessellation repeat unit (molecule) in centimeters.
- Pleat depth ratio
- How much extra paper each pleat consumes as a ratio of molecule size. Shallow pleats ≈ 0.3, deep ≈ 1.0+.
- Border margin (cm)
- Minimum untiled margin around the edges for finishing/anchoring.
What each result means
- Repeats per axis
- Number of molecule repeats fitting along one side of the paper.
- Total molecules
- Total tessellation units in the grid (rows × columns).
- Effective spacing (cm)
- Actual center-to-center spacing including pleat consumption.
- Actual border (cm)
- Resulting border margin on each side after fitting the grid.
- Visible area (cm²)
- Surface area of the visible tessellation pattern.
- Coverage (%)
- Percentage of total paper area covered by the visible pattern.
- Paper in pleats (cm²)
- Estimated paper area consumed by pleats underneath the surface.
- Min paper for this grid (cm)
- Minimum paper side length needed for the calculated grid size.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersPaper size (cm) = 25, Molecule size (cm) = 3, Pleat depth ratio = 0.5, Border margin (cm) = 1 = 4 input(s) provided
- Calculate Repeats per axisRepeats per axis5 = 5
- Calculate Total moleculesTotal molecules25 = 25
- Calculate Effective spacingEffective spacing = moleculeSize * (1 + pleatDepth)4.5 = 4.5
- Calculate Actual borderActual border = (paperSize - gridCoverage) / 21.25 = 1.25
