How to use this tool

  1. Enter spine length, head margin, tail margin, and number of holes in the displayed units.
  2. Calculate and use each labeled result for bookbinding sewing hole layout. Compare the result with a measured sample before committing materials.

Try this example

{
  "spine": 210,
  "head": 15,
  "tail": 15,
  "holes": 7
}

Accuracy and scope

Even spacing template only; sewing structure and paper strength determine the appropriate hole count.
