What is the space between lines of a paragraph called in Microsoft Word?

The space between lines of a paragraph in Microsoft Word is called Line Spacing. This feature allows users to adjust the vertical distance between lines of text within a paragraph, commonly set to single, 1.5 lines, or double. Paragraph Spacing refers to the space before or after an entire paragraph. Indentation controls the distance of the paragraph from the page margins. Margin refers to the blank space around the edges of the page itself. Therefore, Line Spacing is the precise term for the vertical distance between text lines.
