I have a certain layout in word document that is 250 pages. Unfortunately, it has 0.5 page margins. Is there a way to simply increase the paper/page size so that I will have 1 inch margins without messing up the look/format of my text?
On the Page Layout tab click on "Size." From the dropdown options choose "More Paper Sizes." Specify the width and height you want (in your case 9 x 11.5). Then click the Margins tab in the open Page Setup dialog box, enter 1" for all margins, and click OK.
