You can change the default settings for new documents by making changes to the Normal template that new documents are based on. You can modify the Normal template to change its default formatting or content so that any new document that you create will use the new settings.
Important: If you mistakenly modify the Normal template, you can easily restore the default behavior by deleting, renaming, or moving it. The Normal template is automatically recreated the next time that you open Word. However, the same cannot be said for other templates. You should always create a copy of any other template before you change it.
Changing the default font in any template means that the font is used in every new document that is based on that template. For example, the default font for new blank documents is based on the Normal template.
Note: Most of the styles in Word are based on the Normal style. Changing the default font also changes the Normal style, which affects any other style that is built on the Normal style.
Changing the default character spacing in any template means that the settings for scale, spacing, position, kerning, and other typographic features are used in every new document that is based on that template. For example, the character spacing for new blank documents is based on the Normal template.
Changing the default margins in any template means that the margin settings are used in every new document that is based on that template. For example, the margins for new blank documents are based on the Normal template.
Changing the default layout in any template means that the section breaks, headers and footers, and other layout attributes are used in every new document that is based on that template. For example, the layout attributes for new blank documents are based on the Normal template.
You can customize the Normal template and change default settings for many aspects of a document, such as text formatting, paragraph formatting, document formatting, styles, text, pictures, AutoText entries, and keyboard shortcuts. To make changes to Normal.dotm, you must open the file from Word. If you open Normal.dotm from the Finder, Word will create a new blank document based on the template.

You can change the page margins in your doc and create custom margins. But the next time you create a new document, Word for the web will revert to the Normal margin setting of one inch on each side of the page.
