Ries

A German unit of count used for sheets of paper. Prior to 1877, 1 Ries of writing paper was 480 sheets, and 1 Ries of printing paper was 500 sheets. After 1877, the Ries (or Neuries, “new ries”) = 1000 sheets of paper.

At a meeting in Dresden in April 1875, representatives of the German and Austro-Hungarian paper manufacturers and printers agreed to redefine the Ries and Buch, effective 1 January 1876. They also agreed the standard package would contain 500 sheets. The Dresden meeting set the stage for meetings in Vienna (8 May 1875) and Berlin (21 May 1875) at which it was agreed to size paper in centimeters.

The new definitions acquired legal force through actions of the German Reichskanzleramt (21 December 1875) and the Austrian Handelsministerium (16 February 1876). The Germans adopted 1 January 1876 as the date on which the new definitions would become effective, but the Austrians chose 1 January 1877.
