Margins
Page margins should be one inch on each side.
If your computer's measuring system is set in centimeters, set
each side to 2.5 cm. To adjust the page margins, follow these
2 steps:
Step one. Press
page setup under the file menu.

Step two. In
the Page Setup dialog box, under the Margins tab, set all your
margins to 1" (or 2.5 cm). Make sure the gutter is set
at 0".

That's it.
