A historic book size resulting from folding a single standard sheet of paper to produce 24 leaves, or 48 pages. Books printed in this format are quite small, typically measuring around 3 to 5 inches tall, making them suitable for pocket editions, prayer books, or miniature texts. The imposition for this format is highly complex, requiring careful planning to ensure the pages fall in the correct sequence after folding and trimming.
The antique dealer brought in a rare vicesimo-quarto hymnal for rebinding.
