The em dash—that seemingly simple, yet surprisingly versatile punctuation mark—can add a touch of sophistication and clarity to your writing when used correctly. But mastering its proper formatting can be trickier than you might think. This comprehensive guide will delve into the nuances of em dash usage, covering everything from its purpose and placement to stylistic considerations and keyboard shortcuts.
Understanding the Em Dash
The em dash (—) is a punctuation mark longer than both the en dash (–) and the hyphen (-). It’s primarily used to indicate a break in thought, an abrupt change in tone, or to set off parenthetical information with greater emphasis than commas or parentheses. Think of it as a more forceful comma or a more assertive parenthesis.
The em dash signals a stronger interruption or addition to a sentence. It’s not merely a stylistic flourish; it serves a functional purpose in guiding the reader and shaping the rhythm of your writing.
The Purpose of the Em Dash
The em dash has several key functions in written language. Recognizing these functions is crucial to using it effectively and avoiding misuse.
Indicating an Interruption
One of the most common uses of the em dash is to mark a sudden break in thought or speech. This can be used to simulate spontaneous dialogue or to add a dramatic pause. For instance, “I was about to say—but then I realized it was better left unsaid.”
Setting Off Parenthetical Information
Em dashes can be used to set off parenthetical phrases or clauses that deserve more emphasis than parentheses or commas would provide. This is particularly useful when the information is closely related to the main clause but could potentially disrupt the flow if placed within the sentence using commas. Example: “The old house—a Victorian mansion with a sprawling garden—stood majestically on the hill.”
Creating Emphasis and Clarification
The em dash can highlight a particular word or phrase, drawing the reader’s attention to it. This is especially useful when you want to emphasize a crucial point or provide a quick clarification. For example, “The solution was simple—elegantly simple.”
Attribution of Dialogue
While not as common as other methods, the em dash can sometimes be used to attribute dialogue, especially in creative writing. This usage is less formal and can add a unique stylistic touch.
Em Dash vs. En Dash vs. Hyphen
It’s important to differentiate between the em dash, the en dash, and the hyphen, as they serve distinct purposes.
- Hyphen (-): Primarily used to join words together to create compound words or to split words across lines. Examples: “well-being,” “state-of-the-art,” “self-sufficient.”
- En Dash (–): Used to indicate a range or connection between two words or numbers. Examples: “pages 10–20,” “the New York–London flight,” “World War II (1939–1945).”
- Em Dash (—): Used to indicate a break in thought, set off parenthetical information, or create emphasis.
Using the wrong dash can lead to confusion and detract from the professionalism of your writing. Always double-check that you’re using the correct punctuation mark for the intended purpose.
Formatting the Em Dash: Spacing Considerations
One of the most debated aspects of em dash formatting is the use of spaces. There are two main styles: the spaced em dash and the unspaced em dash.
Spaced Em Dash
In this style, spaces are placed on either side of the em dash. This style is more common in journalism and some areas of publishing, and is often the preferred style in countries outside of the United States. Example: “The weather was beautiful — a perfect day for a picnic.”
The spaced em dash can improve readability, especially in narrower columns or when the surrounding text is dense.
Unspaced Em Dash
In this style, no spaces are placed on either side of the em dash. This is the more common style in American English and is generally preferred in academic and formal writing. Example: “The weather was beautiful—a perfect day for a picnic.”
The unspaced em dash offers a cleaner, more modern look and is often considered more aesthetically pleasing.
Choosing the Right Style
The choice between spaced and unspaced em dashes often comes down to personal preference, stylistic guidelines (such as those set by a publisher or style guide), and the overall aesthetic you’re aiming for.
Consistency is key. Whichever style you choose, stick with it throughout your document. Mixing spaced and unspaced em dashes will create a jarring and unprofessional effect.
Consider your audience and the context of your writing. If you’re writing for a specific publication or following a particular style guide (such as the Chicago Manual of Style or the AP Stylebook), adhere to their guidelines. If you have more freedom, experiment with both styles to see which one you prefer.
Creating the Em Dash: Keyboard Shortcuts and Methods
Creating an em dash can vary depending on your operating system, software, and keyboard layout. Here are some common methods:
Windows
- Alt Code: Hold down the Alt key and type 0151 on the numeric keypad. This is the most reliable method across different Windows applications.
- Microsoft Word: Type two hyphens (–) in a row and Word will automatically convert them to an em dash. You may need to ensure autocorrect settings are enabled for this to work.
macOS
- Option + Shift + Hyphen: Press and hold the Option and Shift keys, then press the hyphen key. This is the standard shortcut for creating an em dash on macOS.
- Character Viewer: Open the Character Viewer (Edit > Emoji & Symbols) and search for “em dash.” You can then insert it into your document.

Knowing multiple methods for creating an em dash can save you time and frustration. Experiment with different shortcuts to find the one that works best for you.
Common Mistakes to Avoid
While the em dash is a versatile punctuation mark, it’s easy to misuse it. Here are some common mistakes to avoid:
Overuse
Using too many em dashes can make your writing seem choppy and disjointed. Reserve them for situations where they are truly needed for emphasis or clarity.
Think of the em dash as a spice—a little goes a long way.
Incorrect Spacing
Inconsistently spacing em dashes can detract from the professionalism of your writing. Choose a style (spaced or unspaced) and stick with it.
Misusing as a Hyphen or En Dash
Using an em dash in place of a hyphen or en dash is a common mistake. Remember that each punctuation mark serves a distinct purpose.
Using with Other Punctuation Redundantly
Avoid using an em dash immediately before or after other punctuation marks like commas, periods, or question marks unless there’s a very specific reason to do so. For example, avoid constructions like “,—”.
Using in Formal Writing Excessively
While the em dash can add flair to your writing, it’s generally best to use it sparingly in formal writing. Overreliance on em dashes can make your writing seem less polished and professional.
Stylistic Considerations
The em dash is not just a grammatical tool; it’s also a stylistic choice. Its use can subtly influence the tone and rhythm of your writing.
Tone and Emphasis
The em dash can add a sense of urgency, drama, or informality to your writing. It can also be used to create a more conversational tone, as if you’re speaking directly to the reader.
Consider the overall tone of your writing when deciding whether to use an em dash. If you’re aiming for a formal and objective style, you may want to use em dashes sparingly.
Rhythm and Flow
The em dash can create pauses and breaks in your writing, influencing its rhythm and flow. Use it strategically to emphasize key points and guide the reader through your text.
Consistency in Style
Maintaining consistency in your use of em dashes, including spacing and frequency, is crucial for creating a polished and professional look.
Em Dash in Dialogue
Em dashes can be very effective in dialogue to indicate interruptions, hesitations, or sudden changes in thought. Example: “I wanted to tell you—no, it’s nothing.”
Conclusion
The em dash is a powerful punctuation mark that can enhance your writing when used correctly. By understanding its purpose, mastering its formatting, and avoiding common mistakes, you can leverage the em dash to add clarity, emphasis, and stylistic flair to your work. Whether you prefer the spaced or unspaced style, consistency and thoughtful application are key to harnessing the full potential of this versatile punctuation mark. So go forth and dash—with confidence!
What is an em dash and why should I use it?
An em dash is a punctuation mark that’s longer than an en dash or a hyphen. It’s primarily used to set off a word or phrase in a sentence, creating a stronger break than commas or parentheses. Think of it as a way to add emphasis or indicate an abrupt change in thought.
Using em dashes effectively can improve the clarity and flow of your writing. They allow you to insert extra information, add a parenthetical comment, or create a dramatic pause. Mastering the em dash will give you more control over the rhythm and impact of your sentences, making your writing more engaging and impactful.
How do I type an em dash on different operating systems?
The method for typing an em dash varies depending on your operating system. On Windows, you can typically use the keyboard shortcut Alt + 0151 (hold down the Alt key while typing 0151 on the numeric keypad). Alternatively, Microsoft Word often automatically converts two consecutive hyphens into an em dash as you type.
On macOS, the most common shortcut is Option + Shift + Hyphen. Many word processing programs and text editors also have a ‘Symbols’ or ‘Insert Special Characters’ menu where you can find and insert an em dash. Furthermore, you can set up a custom keyboard shortcut within your system settings if you frequently use em dashes and want a more personalized solution.
Should I use spaces around em dashes?
Whether to use spaces around em dashes depends on the style guide you’re following. In American English, it’s common to use unspaced em dashes, meaning the dash is directly connected to the words on either side. This is the preferred style in publications like the Chicago Manual of Style.
However, in British English and some other European languages, spaced em dashes are often preferred. In this style, a single space is placed both before and after the em dash. Always check the specific style guide required for your writing to ensure consistency.
When is it appropriate to use an em dash instead of other punctuation marks like commas or parentheses?
Em dashes, commas, and parentheses all serve to set off information within a sentence, but they differ in their level of emphasis. Use an em dash when you want to create a stronger break or emphasize the inserted information. They signal a more abrupt interruption or highlight a particular phrase.
Commas are generally used for gentler interruptions, while parentheses offer the least emphasis and are suitable for supplementary information that isn’t crucial to the sentence’s core meaning. Consider the impact you want to achieve and choose the punctuation mark that best conveys your intended meaning.
Can I use multiple em dashes in a single sentence?
While it’s technically possible to use multiple em dashes in a single sentence, doing so is generally discouraged. Overuse of em dashes can make your writing appear disjointed and difficult to read. It’s better to aim for clarity and conciseness.
If you find yourself needing multiple em dashes, consider whether you could restructure the sentence or use alternative punctuation marks like commas or parentheses. In some cases, breaking the sentence into two separate sentences might be the most effective solution for maintaining readability.
Is there a difference between an em dash and an en dash?
Yes, there’s a distinct difference between an em dash and an en dash, primarily in their length and usage. An em dash is longer and typically used to set off phrases or clauses within a sentence, indicating a break in thought or adding emphasis, as previously discussed.
An en dash, which is shorter than an em dash but longer than a hyphen, is primarily used to indicate ranges (e.g., 2020–2024) or connections between related terms (e.g., New York–London flight). Confusing the two can lead to stylistic errors, so it’s important to understand their specific functions.
How do I ensure my em dashes are displayed correctly across different platforms and devices?
Ensuring consistent display of em dashes across different platforms involves using the correct character encoding. The most widely supported character encoding is UTF-8, which is the standard for web pages and most modern text editors. Make sure your document or web page is saved with UTF-8 encoding.
Additionally, using standard fonts that include the em dash character can help prevent display issues. Common fonts like Arial, Times New Roman, and Calibri typically render em dashes correctly. If you’re still experiencing problems, try using the HTML entity code for the em dash, which is —, in web development.
