When figuring book spine dimensions in the USA we use the attribute of the interior paper used called PPI or pages per inch. The page count is divided by the PPI, a small factor for the cover thickness is added and the result is the spine width in inches.
Printers here will either quote the PPI or at least provide a method to calculate it. In the metric world things are different of course. What is the attribute of paper stock equivalent to PPI? How is it used to calculate the spine dimensions? All replies appreciated.
