How can you change the font size in a word processor?

Changing the font size in a word processor is accomplished by accessing the font settings in the toolbar. Typically, word processing software features a toolbar that prominently displays options for font manipulation, including size adjustments. Users can easily select their desired font size from a dropdown menu or by entering a specific number, allowing them to tailor the text's appearance to meet their needs.

The other options address different aspects of document formatting. Adjusting the spacing between lines pertains to line spacing settings and does not directly affect font size. Changing the document layout involves altering the overall structure of the document, such as margins and orientations, but does not influence how large or small the text appears. Inserting page numbers is related to document pagination and has no connection to font size changes.
