Which Word tab enables you to change margin settings?

The Layout tab in Microsoft Word is where you can change margin settings. This tab provides access to various page layout options, including margins, orientation, size, columns, and indentation. By clicking on the "Margins" option within the Layout tab, you can select from preset margin configurations or create custom margins that fit your document needs.

The other tabs serve different functions: the Home tab primarily focuses on text formatting and paragraph styles; the Insert tab is used for adding various elements like tables, images, and shapes; and the Review tab is mainly for document editing, tracking changes, and adding comments. This distinction helps users efficiently navigate Word based on the tasks they wish to perform.
