Microsoft Word has a page size limit of 22 inches by 22 inches. I would like to use a page size of 30x42 with newspaper column formatting. I want to use OLE linking to bring my Libre Writer document into an Autocad drawing.
Writer has a (arbitrary basically and it’s technically trivial to change it) max size settable in the UI of 300cmx300cm which is approx 118"x118" which should be big enough for you
