How to Insert a Horizontal Rule in Microsoft Word

1. Open a document in Microsoft Word. Click wherever you want the horizontal line to appear.
2. Click the 'Home' tab on the Word Ribbon if it is not active already. In the Paragraphs group on the right of the Paint Bucket tool, look for the Borders tool. The Borders tool looks like a group of four squares. Click the drop-down arrow on the tool.
3. Click 'Horizontal Line' from the list of border types. Word inserts a horizontal line where you clicked on the document earlier.
