How to Use This Calculator
  1. Enter the base sheet weight (GSM) of your uncoated paper.
  2. Input the wet coating applied per side (g/m²) and solids content (%) from your formulation.
  3. Set the number of sides coated — 1 for C1S, 2 for C2S.
  4. Enter the coating material cost per kilogram.
  5. Review Dry Coating per Side, Coated Sheet GSM, Water to Evaporate, and Cost per 1,000 m².

What each input means

Base sheet (GSM)
Uncoated base sheet weight in grams per square meter.
Wet coating (g/m²/side)
Wet coating applied per side in g/m².
Coating solids (%)
Solids content of the coating suspension (typically 55-70%).
Sides coated
1 = C1S (one side), 2 = C2S (both sides).
Coating cost ($/kg)
Cost of dry coating material per kilogram.

What each result means

Dry coating/side (g/m²)
Dry coating weight deposited per side.
Total dry coating (g/m²)
Total dry coating weight on the sheet (both sides if C2S).
Coated sheet (GSM)
Total weight of the finished coated sheet.
Coating % of sheet
Coating weight as percentage of total sheet weight.
Water to evaporate (g/m²)
Total water that must be evaporated during drying.
Cost per 1000 m² ($)
Coating material cost per 1,000 square meters of paper.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Base sheet (GSM) = 70, Wet coating (g/m²/side) = 25, Coating solids (%) = 65, Sides coated = 2 = 5 input(s) provided
  2. Calculate Dry coating/side
    Dry coating/side = wetCoatingGSM * (solidsPct / 100)
    16.25 = 16.25
  3. Calculate Total dry coating
    Total dry coating = dryCoatingPerSide * sidesCoated
    32.5 = 32.5
  4. Calculate Coated sheet
    Coated sheet = baseSheetGSM + totalDryCoating
    102.5 = 102.5
