Check that a saddle-stitched page count works in fours and estimate the folded sheets needed.
6 folded sheets per copy
600 sheets across 100 copies.
Each folded sheet contributes four booklet pages, so the total page count is divided by four and multiplied by the number of copies.
Count every page, including blanks and covers, unless the product specification says otherwise. This tool does not impose or reorder PDF pages.
