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.
