What formatting option should you use for titles or headings?

Using larger font sizes and bold formatting for titles or headings is an effective way to make these important elements stand out in a document. This approach conveys hierarchy and structure within the text, guiding the reader's eye to key sections of the content. Larger font sizes ensure that titles and headings are easily noticeable, which is crucial for readability and organization in any written piece. Additionally, bold formatting adds an extra layer of emphasis, helping to differentiate headings from the body text. Together, these attributes enhance the overall visual appeal and clarity of a document, allowing readers to quickly locate sections of interest.

In contrast, while using italics can emphasize certain words or phrases, it often doesn't provide the clear distinction needed for headings. Decreasing the font size would likely have the opposite effect, making titles less visible. Aligning text to the right generally disrupts standard formatting and is not a typical practice for headings, which are usually centered or aligned to the left in most styles.
