octavo
The octave format or octavo (from Latin octo "eight", abbreviated to 8 ° ) is an old exercise book or book format in which a sheet of paper was folded three times and thus broken into eight sheets. Since each sheet has two pages, the format is 16 pages per sheet of paper.
history
The size of a sheet of paper changed over time. At first it was completely arbitrary and, depending on the age, depended on the size of the bowl.
Since 1883 efforts were made in Germany to standardize the bow sizes. The result was 12 normal formats, of which the number 1 measured 33 × 42 cm unbroken or flat, the octave side was therefore approx. 10.5 × 16.5 cm in size.
Finally, in 1922, the DIN A paper format series , which is still used today , was developed, in which the A5 format corresponds to the eighth-note sheet (Latin octavus ) and is created by folding the single sheet (A2) three times. One side measures 148 × 210 millimeters today.
Several such A5 sheets on top of each other, stapled together in the middle and folded once result in a notebook in DIN A6 format - the so-called octave notebook with mostly 32 or 48 pages.
