This section explains how to calculate the approximate spine thickness and the cover sheet length
and size.
Note that the length and size of a cover sheet depends on the thickness of the book block spine.

(20.0 lb. Bond) paper:
• 10-sheet book block: 1 mm (0.04 inches)
• 30-sheet book block: 3 mm (0.12 inches)
• 50-sheet book block: 5 mm (0.20 inches)
• 80-sheet book block: 8 mm (0.32 inches)
• 100-sheet book block: 10 mm (0.40 inches)
• 200-sheet book block: 20 mm (0.80 inches)
Specify the cover sheet size based on the thickness of the book block spine. Use the following
equation to calculate the length of the cover sheet:
Minimum length of cover sheet (mm/inch) = "length of book block sheet (mm/inch)" × 2 +
"thickness of spine (mm/inch)"
To perfect bind a booklet with the following dimensions, specify a cover sheet length of at least
