Flute height (mm)

3.6

Take-up factor1.43
Board caliper (mm)4.17
Board weight (g/m²)581.6
Medium area needed (m²)1.43
Total weight (kg)0.58

How to Use This Calculator
  1. Select the flute type (A, B, C, E, or F) for your corrugated board.
  2. Enter liner weight (GSM) and medium weight (GSM) for your substrate.
  3. Select wall type — single, double, or triple wall.
  4. Enter the total board area (m²) you need to produce.
  5. Review Flute Height, Take-Up Factor, Board Caliper (mm), Board Weight (g/m²), and ECT Estimate.

What each input means

Flute type
0 = A-flute, 1 = B-flute, 2 = C-flute, 3 = E-flute, 4 = F-flute.
Liner weight (GSM)
Linerboard weight in grams per square meter (each liner layer).
Medium weight (GSM)
Corrugating medium weight in grams per square meter.
Wall type
0 = Single wall, 1 = Double wall, 2 = Triple wall.
Board area (m²)
Total area of corrugated board to produce in square meters.

What each result means

Flute height (mm)
Height of the corrugated flute profile.
Take-up factor
Ratio of medium length to liner length (wave stretch factor).
Board caliper (mm)
Total combined board thickness including liners and fluting.
Board weight (g/m²)
Total combined board weight per square meter.
Medium area needed (m²)
Square meters of corrugating medium needed (more than board area due to take-up).
Total weight (kg)
Total weight of board for the specified area.
ECT estimate (lbs/in)
Estimated Edge Crush Test strength.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Flute type = 2, Liner weight (GSM) = 200, Medium weight (GSM) = 127, Wall type = 0 = 5 input(s) provided
  2. Calculate Flute height
    Flute height = flute.heightMm
    3.6 = 3.6
  3. Calculate Take-up factor
    1.43 = 1.43
  4. Calculate Board caliper
    Board caliper = flute.heightMm * mediumLayers + linerThicknessMm * linerLayers
    4.17 = 4.17
