the roll is one of the partially preserved, basically better in the lower part. only column 8 contains parts of all four edges, from most other columns usually only the lower one as well, parts of the right or left edge. reconstruction attempts show that the average number of lines per column is about 42. in contrast, in the back part, which can be assigned to another hand, the letters are written larger, and therefore the columns contain only 33 lines. the columns therefore had a height of about 27 cm. the column width, however, varies between 7.5 and 9 cm or 29 and 43 letters, in the back even only 22-24 letters. this is apparently related to the width of the individual leather sheets sewn together into a roll. while the sheets themselves were different in width, the columns appear to have been drawn relatively evenly on a sheet. the height of the roll can finally be determined with about 35 cm. calculations on the number of columns depend very much on what content the role had. assuming an originally complete twelve-prophecy book, the role should have included between 80 and 94 columns, which would correspond to about 9.6 – 10 m. the role would be longer than any surviving scrolls from qumran. however, only parts of the books jonah, micah, nahum, habakkuk, zephaniah and zechariah are identified.
