How to Use This Calculator

Select the paper type you plan to use: Tant/treated, Elephant Hide/Biotope, watercolor paper, or mulberry/handmade.
Enter the side length of your paper in centimeters.
Choose the desired stiffness level: light for flexible results, medium for models that hold shape, heavy for stiff display pieces.
Enter the number of sheets you plan to treat in this session.
Read the methylcellulose concentration percentage and mix that amount of MC powder with the calculated water volume.
Apply the sizing with the indicated spray mists per sheet and allow the finished model to dry for the estimated hours before displaying.

What each input means

Paper type (1-4): 1=Tant/treated, 2=Elephant Hide/Biotope, 3=Watercolor paper, 4=Mulberry/handmade.
Paper size (cm): Side length of the square paper in centimeters.
Stiffness level (1-3): 1=Light (flexible, forgiving), 2=Medium (holds shape), 3=Heavy (very stiff, display pieces).
Number of sheets: How many sheets of paper you plan to treat with sizing.

MC concentration (%): Methylcellulose percentage in the sizing solution.
Total solution needed (ml): Total volume of MC sizing solution to prepare.
MC powder (grams): Amount of methylcellulose powder to mix.
Water (ml): Amount of water for the sizing solution.
Dampening level (%): How wet to make the paper before folding (% of full saturation).
Spray mists per sheet: Approximate number of spray bottle mists per sheet for even dampening.
Drying time (hours): Estimated drying time for the finished wet-folded model.
Solution per sheet (ml): Volume of sizing solution needed per sheet.

Identify Input Parameters
4 parameters
Paper type (1-4) = 2, Paper size (cm) = 25, Stiffness level (1-3) = 2, Number of sheets = 5 = 4 input(s) provided
Calculate MC concentration
3 = 3
Calculate Total solution needed
Total solution needed = solutionPerSheet * numSheets
12.5 = 12.5
Calculate MC powder
MC powder = (mcPct / 100) * totalSolution
0.38 = 0.38
Calculate Water
Water = totalSolution - mcGrams
12.1 = 12.1
