The Ultimate Guide to Punctuation
When to use an Em Dash (—)
- ✓ To create a strong break in a sentence (stronger than a comma)
- ✓ To replace commas, parentheses, or colons for emphasis
- ✓ To indicate interrupted dialogue in fiction
- ✓ To attribute a quote to an author
When to use a Hyphen (-)
- ✓ To join compound words (e.g., check-in, real-time)
- ✓ For phone numbers (555-0123) and dates (2025-12-13)
- ✓ For URLs (e.g., contentdetector.io/tools/em-dash)
- ✕ NEVER use a hyphen for a pause or break!
Hyphen vs. En Dash vs. Em Dash: The Trio
Many writers claim to "know their dashes," but most get confused between the three main types. Here is the definitive breakdown:
| Mark | Name | Width | Function |
|---|---|---|---|
| - | Hyphen | Narrow | Connects words (compound adjectives) |
| – | En Dash | Width of "N" | Ranges (1990–2000), Scores (21–17) |
| — | Em Dash | Width of "M" | Breaks, pauses, emphasis, interruptions |

AP Style vs. Chicago Style: The Spacing Debate
One of the biggest arguments in typography is whether to put spaces around an em dash. Here is what the major style guides say:
AP Style Use Spaces
Used by newspapers (Associated Press) and many online blogs. They prefer spaces (open em dash) for readability on narrow columns and screens.
Chicago / MLA No Spaces
Used by book publishers and academia. They prefer no spaces (closed em dash) for a seamless look that connects the fragmented thoughts.
Our Tool supports both! Just use the "Add Spaces" toggle above to switch between AP Style (Space) and Chicago Style (No Space).
