Misusing punctuation marks can often lead to confusion in writing. While hyphens and dashes may look similar, they serve very different purposes. Learning when to use a hyphen vs dashes can improve clarity, make your writing more professional, and avoid common mistakes.
In this article, we’ll break down the key differences between hyphens and dashes, their uses, and common pitfalls so you can master these tiny, yet essential, punctuation marks.
What is a Hyphen?
A hyphen (-) is the smallest horizontal punctuation mark. It’s often used to join words or parts of words together, making the text easier to read and understand. Even though it’s small, a hyphen can change the meaning of a sentence, so it’s essential to use it correctly.
Uses of Hyphens
- Compound Words
Hyphens are primarily used in compound words, linking two or more words to create a single meaning. For example:
- Well-known author
- Mother-in-law
These hyphenated words create clarity. Without the hyphen, the words could have different meanings, which could confuse the reader. For instance, “well known” without a hyphen may imply “known in a good way,” while “well-known” refers to something or someone famous.
- Word Breaks at the End of a Line
In printed texts, hyphens are used to break words at the end of a line when the entire word cannot fit. This is less common in digital writing but can still appear in justified text formats:
- “The group decided to dis- cuss the matter further.”
- Numbers and Fractions
When writing numbers or fractions, hyphens are often used for consistency:
- Twenty-one
- One-third of the cake
- Prefixes and Suffixes
Hyphens are used when adding prefixes like ex-, self-, or all- to words. They are also used to avoid confusion with similar words:
- Ex-husband
- Self-esteem
- All-inclusive
Common Mistakes with Hyphens
Many writers mistakenly overuse or underuse hyphens in compound words. Some common errors include hyphenating words that don’t need it, such as “high-school” (should be “high school” unless it’s an adjective like “high-school student”). Always consult a trusted dictionary or style guide for compound words and prefixes to avoid these mistakes.
Understanding Dashes
What is a Dash?
Dashes, unlike hyphens, are longer and serve a different function in writing. There are two main types of dashes: the en dash (–) and the em dash (—). Each has its unique role and is longer than a hyphen.
Types of Dashes
- En Dash (–)
The en dash is slightly longer than a hyphen and is used primarily to represent a range or a connection between numbers, dates, or locations:
- 1990–2000 (representing a time range)
- The London–Paris flight (indicating a connection between places)
The en dash is commonly mistaken for a hyphen, but it is vital to use the right mark in formal writing, especially in documents like resumes or reports.
- Em Dash (—)
The em dash is the longest of the three marks and is used to add emphasis, replace commas, parentheses, or even colons in informal writing. It often creates a dramatic pause:
- “He was late—again.”
- “The three things I need—milk, bread, and cheese—were all out of stock.”
The em dash is highly versatile and is often preferred in creative or informal writing for its ability to break up thoughts and add emphasis.
Hyphen vs Dashes – Key Differences
Now that we’ve defined each, let’s look at the differences between hyphens and dashes.
- Length and Appearance
- Hyphen: Shortest ( – )
- En Dash: Medium length ( – )
- Em Dash: Longest ( — )
- Usage in Writing
- Hyphen: Used for compound words, prefixes, and word breaks.
- En Dash: Represents ranges (e.g., “pages 34–36”) or connections (e.g., “The New York–London flight”).
- Em Dash: Adds emphasis, breaks thoughts, or can replace commas and parentheses.
- Example Comparison
- Hyphen: “Check-in time is 2 p.m.”
- En Dash: “The New York–London flight was delayed.”
- Em Dash: “He was late—again.”
Common Mistakes with Dashes
Because hyphens and dashes look similar, it’s easy to confuse them. Here are some frequent errors:
- Using Hyphens Instead of Dashes
Many writers accidentally use a hyphen where a dash is needed, especially in informal writing. For example:
- Incorrect: “She was late – again.”
- Correct: “She was late—again.”
In this case, the em dash adds the dramatic pause that a hyphen can’t provide.
- Double Hyphen for Em Dash
In informal typing, people often use two hyphens (–) instead of an em dash, particularly when they don’t know how to type it. However, using an actual em dash adds professionalism to your writing. - Overuse of Em Dashes
While em dashes are versatile, overusing them can make your writing feel disjointed. Use them sparingly for emphasis, and try not to replace every comma or parentheses with an em dash.
Tips for Correct Usage

Conclusion
In summary, understanding the differences between a hyphen vs dashes is essential for clear and polished writing. While hyphens connect words or parts of words, dashes, especially en dashes and em dashes, serve entirely different functions. The next time you write, be mindful of these tiny punctuation marks, and your writing will be more precise and professional.
So, practice using hyphens, en dashes, and em dashes correctly—and see how much clearer your writing becomes!
FAQs: Hyphen vs Dashes
What’s the difference between a hyphen and a dash?
A hyphen (-) is used to connect words, such as in compound words (e.g., “well-known”) or to break words at the end of lines. Dashes, on the other hand, come in two types—en dash (–) and em dash (—)—and are longer than a hyphen. The en dash is used to represent ranges or connections (e.g., “1990–2000”), while the em dash is used to add emphasis or create a pause in sentences (e.g., “She was late—again”).
When should I use a hyphen instead of a dash?
Use a hyphen when:
Forming compound words (e.g., “well-known”).
Breaking words at the end of lines.
Writing out fractions or numbers (e.g., “twenty-one” or “one-third”).
Using prefixes like ex- or self- (e.g., “ex-husband,” “self-esteem”).
What is an en dash, and how is it different from a hyphen?
An en dash (–) is slightly longer than a hyphen and is used to indicate a range (e.g., “pages 10–20”) or a connection between two things (e.g., “New York–London flight”). A hyphen is shorter and used to combine words or break words.
How do I type an em dash on my computer?
To type an em dash (—):
On Windows: Press Alt + 0151.
On Mac: Press Shift + Option + Minus.
What’s the difference between an en dash and an em dash?
The en dash (–) is used for ranges (e.g., “Monday–Friday”) and to connect two related elements (e.g., “New York–London”). The em dash (—) is longer and used to add emphasis, break a sentence, or replace commas and parentheses for a dramatic pause (e.g., “I need three things—coffee, patience, and quiet”).
Can I use two hyphens instead of an em dash?
While many people use two hyphens (–) as a substitute for an em dash, it’s more professional to use an actual em dash (—) in formal writing. Most word processors automatically convert two hyphens into an em dash, but you can also type it directly using shortcut keys.
Is it okay to overuse the em dash?
No, overusing the em dash can make your writing feel disjointed. While the em dash is versatile, use it sparingly to maintain the flow and coherence of your writing. Too many em dashes can be distracting to the reader.
Should I use a hyphen or an en dash for date ranges?
You should use an en dash (–) for date ranges (e.g., “1995–2000”), not a hyphen. The en dash shows the span between the two dates, while a hyphen is not appropriate for this purpose.
Can hyphens and dashes be used interchangeably?
No, hyphens and dashes serve different purposes. Hyphens are used to connect words, while dashes (en dash and em dash) are used for different punctuation purposes, such as indicating ranges, breaking thoughts, or adding emphasis.
Are hyphens or dashes more common in formal writing?
Both hyphens and dashes are common in formal writing, but they serve different functions. Hyphens are used more frequently for compound words and prefixes, while dashes (especially em dashes) are used to add emphasis or structure to sentences.
