Very large paper height in Microsoft Office Word
Is it possible to set the paper height to infinity or a very large value in Microsoft Office Word? How I can do this?
The maximum paper size limit is 22" x 22" (55.88cm x 55.88cm)
as described in Operating parameter limitations and specifications in Word. You can't go above that.
From Printing Very Large Paper Sizes:
Word is hard-coded to permit document widths and heights as small as .1 inches and as large as 22 inches. Thus, the largest page area you can define in Word is 22 inches by 22 inches. This is an absolute limit. If you need to print to larger paper, then you will need to use a different program, such as a desktop publishing program.
