Shapes and sizes of manuscripts

Watch the video Prof. Sasaki explains the relationship between paper and the book size.

Although most literary works made between the late-Heian and Muromachi periods were bound in the tetsuyōsō (multisection) style, there was some variation in shape and size. How many different sizes were used? What determined the choice of one shape or size over another?

First, read the following article about the six most common formats, and then, watch Prof. Sasaki explain the details by showing you examples.

  1. Yotsuhan-bon (quarter-size books)
  2. Mutsuhan-bon (sixth-size books)
  3. Yokonaga-bon (“Wider-than-high” books)
  4. Yatsuhan-bon (“eighth-sized” books)
  5. Masugata-bon (Square books)
  6. Oversized books


Generally speaking, book size depends on the size of the paper used. Despite minor differences by place and date of manufacture, in the 16th century the size of a typical sheet of hishi paper—the one used for tetsuyōsō binding—was 54 x 37 cm. To make a book, the sheets were cut in half, stacked on one another, folded in two, and then bound together in sets of about five. The size of the resulting book was 18.5 x 27cm (as the edges were trimmed the actual final size was slightly smaller). Paper sizes seem to have been smaller in the Edo period, and so were book sizes; the majority of books are approximately 17 cm wide and 24 cm high. Kamakura-period books tend to be smaller and slightly narrower in width. As standard tetsuyōsō books made of sheets cut in half and folded in two were one fourth of a hishi paper sheet in size, they are often referred to as quarter-size books (yotsuhan-bon). This example (Fig.1) is a Kamakura-period manuscript and it is lightly smaller than usual, measuring 16 x 23.2 cm. Yotsuhan-bon are the most common type of tetsuyōsō books.

Next in popularity are the mutsuhan-bon (sixth-size books) which are so called because the sheet was cut into three sections instead of two, and so the size of the finished book is one sixth of the original sheet (approximately 18.5 x 18 cm before the trimming). As most books in this format from the Kamakura and Edo periods are 15 cm long on all four sides, they are sometimes called masugata-bon (square books). This specimen of mutsuhanbon (Fig.2) was not trimmed, so it is slightly larger than average (17.8 x 17.5 cm).

Yotsuhan-bon and mutsuhan-bon were the most common sizes, but there were also some unusual ones, like the yokonaga-bon (“Wider-than-high” books). They were made by cutting the sheets lengthwise rather than across, resulting in a yotsuhan book with wide but very “short” pages.


More common were the yatsuhan-bon (“eighth-sized” or octavo books), which were made by folding the page of a yotsuhan book in two to obtain a book one-eighth of the size of the original sheet. Books in this format were probably meant to be carried around. This particular item (fig.3) is 8.1 x 12.2 cm.

Compact Masugata-bon

Compact masugata-bon are fairly rare. They were made by first cutting the sheets in half lengthwise and then following the procedure for the mutsuhan-bon. Although the final size was approximately one twelfth of the initial sheet, the appellation twelfth-size books does not seem to have ever been used. This particular book (Fig.4) measures 10.4 x 10.2 cm and the paper used is a type of processed kōzo paper instead of the usual hishi.

Oversized books

A special category are the oversized books, which were mostly manufactured in the Kamakura area during the Kamakura period (1185-1333). There are similar items dating from the Muromachi period, but they tend to be from specific areas and periods of time. This item (Fig.5) was in particularly bad condition, so it was rebound as a musubitoji (knot binding), but even so it measures 21.9 by 28.5 cm.

Edo-period books come in more or less standard formats. We will learn about this in Week 3 of the course.
