Attack on Titan has been collected into 22 tankbon volumes, each with 30 pages.
== Reception ===== Sales ===The manga's publisher, Kodansha, credits Attack on Titan for the company's first revenue increase in eighteen years
 When a series originally published in tankbon format is re-released in wide-ban format, each volume will contain more pages than in the original edition, and therefore the series will consist of fewer volumes
