Double-click the gray area where the ruler does not extend to open the Page Setup dialog box to the Margins tab.
Type the new margin settings (for example, 1 inch in the Left spin box and 1 inch in the Right spin box).
Click the OK button.
View the new page margins applied in the document by looking at the new locations of the indent markers on the ruler.
INTRODUCTION
You can adjust the top, bottom, left, and right margins for a single page or for your entire document. For example, you might need to fit a large amount of text on one page and therefore need to increase the margins for the document's printable area.
TIP
Portrait and Landscape
If you need to alter your page's orientation from portrait to landscape or increase the size of your document (for example, to legal size 8.5"x14"), modify the settings in the Paper Size tab on the Page Setup dialog box.
TIP
Page Setup
You can also open the File menu, select Page Setup, and select the Margins tab to change the margins. Word's default margins are 1" for the top and bottom and 1.25" for the left and right.
