This is not necessarily true at all ...... It's different for each work, monthly works usually have about 30 pages per story, a book has about 6 stories, weekly works usually have about 15 pages per story, a single book has about 11 stories, and in some special cases, if a work has a volume premiere special, that story usually has the usual two stories... Then the single volume will have one less story, and in the case of Arrest Warrant... If the serialization is only 8 pages per story, then a single book will have about 20 stories ==

Some manga, like four-panel comics, have even more stories == one story per page is possible. ....
