How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Armhole Circumference = 18, Sleeve Cap Height = 6, Sleeve Type = 0 = 3 input(s) provided
  2. Calculate Sleeve Cap Circumference
    Sleeve Cap Circumference
    19.5 = 19.5
  3. Calculate Cap Ease Amount
    Cap Ease Amount = 0
    1.5 = 1.5
  4. Calculate Ease Percentage
    Ease Percentage
    8.3 = 8.3
