When should you underline a title is a question that often arises for students, writers, and anyone preparing documents that follow specific formatting rules. Understanding the correct occasions for underlining helps maintain consistency, shows attention to detail, and ensures that your work meets the expectations of teachers, editors, or publishing standards. This guide explores the history behind underlining, the style conventions that dictate its use, and practical tips for applying it correctly in modern writing Less friction, more output..
Historical Background of Underlining Titles
Before the widespread adoption of italics in typesetting, underlining served as the primary method to indicate that a word or phrase should be set in italic type. In handwritten manuscripts and early typewritten documents, underlining signaled to the printer that the marked text needed to be italicized during production. As printing technology evolved, italic fonts became readily available, and the practice of underlining shifted from a production instruction to a stylistic choice in certain contexts.
When Underlining Is Still Appropriate
Although italics have largely replaced underlining in printed and digital media, there are still specific situations where underlining a title remains the correct or preferred approach:
- Handwritten Work: When you are writing by hand—such as in a classroom essay, a personal journal, or a lab notebook—underlining is the standard way to denote titles that would otherwise be italicized.
- Certain Citation Styles: Some older or specialized citation manuals (e.g., certain legal documents or specific disciplinary guides) may still prescribe underlining for case names, statutes, or other legal references.
- Typewriter or Plain‑Text Environments: In contexts where italic formatting is unavailable—such as plain‑text emails, certain coding comments, or legacy systems—underlining (or its surrogate, underscores) can convey emphasis.
- Instructional Materials: Teachers sometimes ask students to underline titles in worksheets to practice identifying works that require italicization, reinforcing the rule before moving to digital formatting.
Modern Style Guides and Their Recommendations
Most contemporary style manuals advise using italics rather than underlining for titles of standalone works. Below is a summary of what major guides say:
| Style Guide | Recommendation for Titles | Note on Underlining |
|---|---|---|
| The Chicago Manual of Style | Italicize books, journals, movies, TV series, albums, plays, long poems, and works of visual art. | Underlining is acceptable only in handwritten work; otherwise, use italics. |
| Modern Language Association (MLA) 9th Edition | Italicize books, periodicals, films, television shows, albums, and longer musical works. | Underlining is discouraged; use italics for all formatted titles. |
| American Psychological Association (APA) 7th Edition | Italicize books, reports, webpages, journals, and audiovisual media. So naturally, | Underlining is not recommended; italics are the standard. |
| Associated Press (AP) Style | Use quotation marks for most titles (books, movies, songs, etc.); italics are not used in AP news copy. | Underlining is not part of AP style; quotation marks serve the purpose. Which means |
| The Bluebook (Legal Citation) | Italicize case names, books, and periodicals; underlining is permitted in handwritten documents or when italics are unavailable. | Underlining is a fallback for non‑print contexts. |
The consensus is clear: italicize titles in typed or digitally produced documents, and reserve underlining for handwritten work or environments lacking italic capability.
How to Properly Underline a Title
If you find yourself in a situation that calls for underlining—most commonly a handwritten assignment—follow these steps to ensure clarity and neatness:
- Identify the Full Title: Write the complete title exactly as it appears on the work, including any subtitles, punctuation, or special characters.
- Use a Straight Line: Place a single, horizontal line directly beneath the text. The line should be as close to the letters as possible without touching them, typically about 1–2 mm below the baseline.
- Maintain Consistent Length: The underline should extend from the first character of the title to the last character, covering spaces and punctuation. Avoid starting or stopping the line in the middle of a word.
- Avoid Over‑Underlining: Do not underline more than once; a double line can be confused with other editorial marks (e.g., proofreading symbols).
- Check for Legibility: Ensure the line is dark enough to be seen but not so heavy that it obscures the letters. A standard pencil or pen pressure works well.
- Review the Context: Verify that the style guide or instructor’s instructions indeed require underlining. If italics are acceptable, consider using them instead for a cleaner look.
Quick Checklist for Handwritten Underlining

- [ ] Single straight line beneath the entire title
- [ ] No gaps or extra marks
- [ ] Line close to text but not touching
- [ ] Legible and neat
Common Mistakes to Avoid
Even experienced writers sometimes slip up when deciding whether to underline. Here are frequent errors and how to correct them:
- Underlining Short Works: Titles of short stories, poems, articles, or episodes should be placed in quotation marks, not underlined or italicized. Underlining them incorrectly suggests they are standalone works.
- Mixing Underlining and Italics: Using both styles in the same document creates visual inconsistency. Choose one method based on the medium and stick with it.
- Underlining URLs or Email Addresses: In plain‑text environments, underlining can be mistaken for a hyperlink. If you need to highlight a web address, consider using angle brackets or a different notation.
- Over‑Underlining Emphasis: Underlining for emphasis (instead of italics or bold) can confuse readers who associate underlining with titles. Reserve underlining strictly for titles unless a specific style guide says otherwise.
Frequently Asked Questions
Q: Can I underline a title in a typed paper if my teacher asks for it?
A: Yes. If an instructor explicitly requests underlining—perhaps to practice handwriting conventions—follow their direction. Otherwise, default to italics for typed work.
Q: What about underlining titles in a PowerPoint presentation?
A: PowerPoint supports italics, bold, and various fonts. Use italics for titles unless the slide design calls for a different visual treatment. Underlining can appear outdated and may be mistaken for a hyperlink.
Q: Is there ever a case where underlining is preferred over italics in digital media?
A: Rarely. Some accessibility guidelines suggest avoiding underlining for non‑link text because users may expect it to be a hyperlink. Italics or bold are safer choices for emphasis.
Q: How do I handle titles that already contain italicized words (e.g., a book title that includes a foreign phrase)?
A: Keep the internal italics as they are and underline the entire title if required. Example:
Answering the Final Question
When a title already contains italicized elements—such as a quoted subtitle, a foreign phrase set apart by small caps, or a stylized word—keep those internal markings unchanged and apply the underline to the whole title block. The goal is to signal “this is a title” without obscuring the nuance that the original formatting was intended to convey. To give you an idea, a title like The Silent Whisper — Whispers in the Night would become
The Silent Whisper — Whispers in the Night
(underlined)
Here each segment remains italicized, while the single line runs beneath the complete string. That's why this approach satisfies most style guides that prescribe “underline the whole title, preserve any existing internal emphasis. ” If a particular publication requires a different hierarchy (for example, keeping the outermost italics and only adding an underline around the entire phrase), follow the specific instruction, but never mix the two techniques within the same title Simple, but easy to overlook. That's the whole idea..
Closing Thoughts
Handling underlining correctly turns a simple typographic rule into a clear visual cue that respects both tradition and modern clarity. Whether you’re writing by hand, drafting a printed essay, or designing a slide deck, remember these core principles:
- Identify what must be highlighted – a full‑length title rather than brief fragments.
- Choose a consistent method – underline for titles, italics for longer passages, and reserve other markup for links or emphasis.
- Preserve internal styling – keep existing italics, quotes, or special characters intact when applying an underline.
- Check against the specific guidelines – some instructors or publishing houses may accept alternatives such as bold or a thick line, but the safest bet is to follow the exact wording of the assignment.
By adhering to these steps, you’ll produce work that looks professional, avoids accidental misinterpretation, and demonstrates attention to detail. Happy writing!
