How do I determine the spine width for catalogues?
The spine width can be calculated from the page number of the inner section and the paper weight:
Spine width = number of pages inner section : 2 x paper weight: 1000
Example:
Catalogue with 128 pages in the inner section and a paper weight of 135 g/m²
Spine width = 128 pages : 2 x 135 : 1000 = 8.64 mm
