Which font size range is most commonly used for headings?

The font size range most commonly used for headings is typically larger to ensure that they stand out and grab the reader's attention. A size range of 18-28 points is appropriate for headings, as it provides visual hierarchy on the page and helps separate the main sections or topics from the body text, which is usually much smaller, often in the range of 10-12 points. This distinction is crucial in effective document design because it aids in organizing content and facilitating better readability. Larger font sizes convey importance and help guide readers through the material. Thus, the selection of 18-28 points for headings aligns with standard typographic practices in both digital and print formats.
