Binding Method
1 = perfect bind, 2 = saddle stitch, 3 = case bind (hardcover).

What each result means

Cover Wrap Width
Total width of cover flat (front + spine + back + bleeds).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Page Count = 200, Paper Caliper (inches) = 0.004, Cover Caliper (inches) = 0.012, Binding Method = 1 = 4 input(s) provided
  2. Calculate Spine Thickness
    0.4 = 0.4
  3. Calculate Total Book Thickness
    Total Book Thickness
    0.424 = 0.424
  4. Calculate Cover Wrap Width
    Cover Wrap Width
    12.65 = 12.65
