What is "line spacing"?

Line spacing refers specifically to the vertical distance between lines of text in a document. It is an important aspect of formatting as it affects the readability of the content. By adjusting line spacing, one can enhance clarity and make the text more visually appealing. For instance, double line spacing provides ample room between lines, making it easier to read and annotate, while single line spacing is more compact and efficient for fitting more text on a page.

The other options address different elements of document formatting. The width of the page margins relates to how much space is left on the sides of the page, while the size of the font concerns the text's scale. The arrangement of text on a page involves how text is positioned, but does not specifically pertain to the spacing between lines within paragraphs.
