Hi i am trying to print on 8.5' x 13' paper. It is the legal paper size in the philippines. Libreoffice calls it 'long bond.' I am using libreoffice Version 4.0.2.2. Whether you're using Microsoft Word or any word processing software, the size of Long Bond Paper in cm (centimeter) is 21.59 cm x 33.02 cm: You just simply convert inches into centimeter. You can use any measuring unit converter in the internet or in Google search itself.
