Understanding Japanese Manga Publishing Volumes (Tankobon)
In Japan, manga is initially serialized on cheap pulp paper in massive weekly or monthly anthology telephone-book magazines (such as Weekly Shonen Jump, Weekly Shonen Magazine, or Young Jump). After an author completes approximately 180 to 220 pages of serialized story, the publisher collects these chapters into a standalone, bound, high-quality paperback book known as a Tankobon (単行本).
Volume Number = Ceiling(Chapter Number ÷ Chapters Per Volume)
Chapter In Volume = ((Chapter Number - 1) Modulo Chapters Per Volume) + 1

Frequently Asked Questions
Due to brutal weekly deadlines, manga artists frequently submit chapters with unfinished backgrounds or rough lineart to magazines. When preparing the compiled tankobon volume, creators fix anatomical errors, add screentones, insert missing backgrounds, and include bonus omake sketches, author Q&As, and character profile cards.
A 100-volume collection (such as One Piece, Detective Conan, or Hajime no Ippo) requires approximately 150 centimeters (59 inches or nearly 5 feet) of contiguous shelf width. Standard IKEA Billy bookcases have 76cm wide shelves, meaning 100 volumes will fill exactly two complete shelf tiers.
