B1 posters are the large-format Japanese theatrical poster size, measuring approximately 73 × 103 cm—around double the area of a standard B2. Produced in far smaller numbers than B2 one-sheets, B1s are noticeably rarer and make a spectacular statement piece when framed, with the extra space allowing for more detailed artwork, larger credit blocks, and dramatic impact on the wall.
