Mike Callahan aka Dr. Filefinder of Butterscotch explains how to adjust the margins in Microsoft Word 2007. While working on a document navigate your mouse to the 'Page Layout' tab at the top, center of the page. On the far left of the resulting page you will find 'Margins', click on that. A drop down window will display some default options that may suit your needs. If not, then click on the bottom option 'custom margins' to change the margin width to any size that you choose. You will now be able to adjust the margins in Microsoft Word 2007.
