If the cover uses different stock or is printed separately, it is not included in this body-sheet count. Keeping “body” and “cover” quantities separate also makes print quotes easier to check.
Folded saddle-stitched booklets are normally arranged in groups of four pages. Sheet count alone does not tell you whether the final page count is suitable for that binding method.
Test prints, damaged sheets and finishing waste are outside this estimate. Real production quantities usually need some allowance beyond the theoretical minimum.
