How to Write Dialogue in a Novel: Rules and Examples

To write dialogue in a novel, give every exchange a job (conflict, information the reader needs, or a change in the relationship). Start a new paragraph each time the speaker changes, and punctuate it to one consistent style. Most of the craft is in what characters avoid saying. Most of the mechanics are about where the commas and quotation marks go.

This guide puts both halves on one page. It covers what dialogue is for, the formatting rules, American and British punctuation side by side, how to pace a scene, and before-and-after rewrites from romance and thriller scenes. For attribution itself (“said”, action beats and when to use neither), see the companion guide to dialogue tags and action beats.

At a glance

Every line of dialogue should do at least one job: raise conflict, reveal character, move the plot or change the pace.
New speaker, new paragraph. That one rule fixes most dialogue formatting problems.
American style uses double quotation marks with commas and full stops inside. British style usually uses single marks, and modern British fiction also puts the comma inside when a tag follows.
Good dialogue sounds natural but is not a transcript. Cut the greetings, the filler and the “as you know” exposition.
Subtext (what a character means but won’t say) is what makes a scene feel alive.
Choose one punctuation style for the whole book and record it on a style sheet for your editor and proofreader.

What dialogue is for

Dialogue is not conversation copied onto the page. Real talk wanders, repeats itself and is full of “um” and “anyway”. Fiction dialogue keeps the feel of speech and drops the dead weight. Before you keep a line, ask what it is doing. A line earns its place if it does one or more of these:

Creates or escalates conflict. Two people want different things and the talk is how they fight for them.
Reveals character. Word choice, rhythm and what someone refuses to answer tell the reader who they are faster than a paragraph of description.
Delivers information the reader needs, at the moment they need it, preferably under pressure.
Controls pace. Short, fast exchanges speed a scene up. Longer speeches and description between lines slow it down.
Changes the relationship. By the end of the exchange, something between the characters should have shifted, even slightly.

Subtext: the part readers remember

Subtext is the gap between what is said and what is meant. A couple arguing about whose turn it is to do the dishes is rarely arguing about dishes. Subtext lets readers work something out for themselves, and that is a big part of why they keep reading. A quick test: if a character states their exact feelings in plain words (“I am angry because you forgot my birthday and it made me feel unimportant”), the line is probably doing too much. Let the anger come out sideways.

Voice: making characters sound different

If you could strip the tags from a page and still tell who is talking, the voices are working. Characters differ in vocabulary, sentence length, formality, humour, what they notice and what they avoid. Point of view matters here as well. In close third or first person, the narrator’s voice colours everything around the dialogue. The guide to choosing first, second or third person explains how that choice affects what your viewpoint character can know and say.

Dialogue formatting rules

These are the rules that hold in almost all commercial fiction, whichever side of the Atlantic you publish on.

Each new speaker gets a new paragraph. Yes, dialogue needs its own paragraph whenever the speaker changes, even if they say only one word.
Keep a speaker’s action and speech in the same paragraph. If Maya slams the door and then speaks, both belong in Maya’s paragraph. Putting one character’s action next to another character’s speech confuses readers about who is talking.
Put the spoken words inside quotation marks. Unspoken thought is usually set in italics or left unmarked, not in quotation marks.
Use a comma, not a full stop, before a speech tag. “I’m leaving,” she said. The tag is part of the same sentence, so “she” stays lower case.
Use a full stop before an action beat. “I’m leaving.” She grabbed her keys. A beat is its own sentence, so it starts with a capital letter.
Question marks and exclamation marks replace the comma. “Are you leaving?” he asked. Not “Are you leaving?,” he asked.
A speech running over several paragraphs opens each new paragraph with a quotation mark and closes only the final one. The missing closing mark tells the reader the same person is still talking.
Interruptions take a dash and trailing off takes an ellipsis. “I didn’t mean—” “Yes, you did.” / “I thought maybe…”

Interrupted and split dialogue

When a tag splits one sentence, the second half continues in lower case: “If you go now,” she said, “don’t come back.” When the tag falls between two complete sentences, the second sentence starts with a capital: “Fine,” she said. “Go.” Chicago-style American usage shows interruption by another speaker with an em dash (—) and no space. Many British publishers use a spaced en dash ( – ) instead. Either works if you are consistent.

American vs British dialogue punctuation

This is the part most dialogue guides skip. The Chicago Manual of Style sets the norm for American fiction. In the UK, publishers have traditionally followed Oxford style, set out in New Hart’s Rules (part of the New Oxford Style Manual). Australian and New Zealand publishers often follow British conventions, but practice varies by house, so check your editor’s or publisher’s preference.

Point	American (Chicago) style	British (Oxford) style
First-level quotation marks	Double: “Come here.”	Single: ‘Come here.’
Quote within dialogue	Single inside double: “She said ‘never’ twice.”	Double inside single: ‘She said “never” twice.’
Comma before a tag	Always inside: “Wait,” he said.	Inside in modern fiction: ‘Wait,’ he said. (Formal and academic writing may put it outside.)
Full stop at the end of speech	Inside: He said, “It’s over.”	Inside when it ends the spoken sentence: He said, ‘It’s over.’
Interruption dash	Unspaced em dash: “I—”	Often a spaced en dash: ‘I –’
Spelling inside dialogue	US spelling (color, realize)	UK spelling (colour, realise)

Two practical points. First, readers notice inconsistency far more than they notice which style you chose. Second, if you write in British English but publish mainly to US readers, either style is acceptable. Pick one, put it on your style sheet and apply it everywhere. The self-editing guide shows how to build a style sheet and run consistency passes.

How to write better dialogue: a scene-by-scene method

Use these steps when drafting a dialogue-heavy scene, or when revising one that feels flat.

Name each character’s goal in the scene. One line each: what do they want from this conversation? If nobody wants anything, the scene is probably exposition and may belong elsewhere.
Find the obstacle. The other character wants something different, is hiding something or simply won’t cooperate.
Enter late, leave early. Skip the hellos and the small talk. Start at the first line that matters and cut away once the shift has happened.
Draft fast, then read it aloud. Your ear catches stiff phrasing and tongue-twisters that your eye misses.
Cut “as you know” exposition. Characters should never tell each other things they both already know just to inform the reader.
Look for the subtext. Where a character states a feeling outright, try showing it through deflection, a change of subject or an action instead.
Check the attribution. Can the reader always tell who is speaking? Add a tag or beat where they can’t, and remove any that only repeat what is already clear.
Vary the rhythm. Break up long runs of one-line exchanges with an occasional beat, thought or longer speech, and vice versa.

Examples by genre, with before-and-after rewrites

All examples below are original and written for this guide.

Romance banter

Before:

“Hello, Jack. It is nice to see you again after five years apart since our break-up,” said Ellie happily.

“Hello, Ellie. I have missed you very much and I still have feelings for you,” Jack replied emotionally.

After:

“You’re in my seat.” Ellie didn’t look up from the menu.

“Your name’s not on it.”

“It was. For three years.” She finally looked at him. “You kept the jacket.”

Jack tugged at the sleeve. “It’s a good jacket.”

The rewrite drops the greeting and the history lesson. It also never names the feeling. The jacket carries the subtext, the reader works out that the seat matters, and the banter has an edge because both of them are pretending not to care. Romance readers expect that tension to build, and dialogue is often where it is most visible. The guide to writing to genre covers more of what romance and other genre readers expect.

Thriller interrogation

Before:

“Where were you on the night of the murder, which was Tuesday the fourth?” asked Detective Rao.

“I was at home all night watching television,” answered Cole nervously, because he was lying.

After:

Rao slid the photo across the table. “Tuesday.”

“Home.” Cole didn’t touch it.

“Alone?”

“I watched the match.”

“Who won?”

Cole blinked. “Does it matter?”

The before version tells us Cole is lying. The after version lets us catch him. Short lines speed the scene up. The photo and Cole’s refusal to touch it do the work an adverb was doing badly, and the question he can’t answer gives him away.

Dialogue rules for specific situations

Phone calls, texts and messages

Phone dialogue is formatted like any other speech. Text messages and emails are usually set apart by italics, a different paragraph style or a simple label. Whatever you choose, keep it consistent and readable on a phone-sized ereader screen.

Dialect and accents

A little goes a long way. Heavy phonetic spelling (“Ah’m gonna git”) tires readers and can come across as mocking. Word choice, grammar and rhythm usually suggest an accent better than altered spelling does.

Foreign languages

Many publishers set foreign words in italics, though some now leave them roman to avoid “othering” a character’s language. Make sure the meaning is clear from context or from how the other character responds.

Internal dialogue

Direct thought (“This is a mistake, she thought”) is often italicised. In deep point of view, many authors drop both the italics and the tag, because the narration is already inside the character’s head.

Common mistakes

Talking heads. Pages of speech with no setting or physical action leave readers unsure where characters are or what they are doing. Add a beat every few lines.
Exposition dumps. “As you know, Bob…” lines exist only to brief the reader. Move the facts into conflict, or trust the reader to pick them up later.
Everyone sounds the same. If all your characters use the same vocabulary and sentence length, rewrite one voice at a time.
Over-attributing. Tagging every line in a two-person exchange is unnecessary once the pattern is set. See the dialogue tags guide for when to tag and when to let the beat do it.
Punctuation drift. Switching between single and double quotes, or em and en dashes, partway through a book. A style sheet prevents this.
Action and speech from different characters in one paragraph. This is the most common cause of “who said that?” confusion.
Too much realism. Including every “um”, “well” and greeting slows scenes to a crawl.
Relying on software alone. Grammar checkers flag some punctuation errors but miss voice and subtext problems. The ProWritingAid vs Grammarly comparison covers what each tool can and can’t catch.

Dialogue revision checklist

Every speaker change starts a new paragraph.
Each character’s action sits in the same paragraph as their speech.
Commas before tags and full stops before beats are used correctly throughout.
One quotation-mark style and one dash style, recorded on the style sheet.
No “as you know” exposition.
Each scene has at least one exchange where the meaning sits under the words.
You could tell the main characters apart with the tags removed.
Read aloud at least once, start to finish.
No greeting or sign-off survives unless it carries tension.

If dialogue is a recurring weak spot in feedback, a line editor can help. The guide to finding the right editor explains the difference between developmental, line and copy editing. If you are still drafting your first book, the step-by-step guide to writing a novel shows where dialogue revision fits in the overall process.

Sources this guide draws on: The Chicago Manual of Style (dialogue and quotation punctuation), New Hart’s Rules and the New Oxford Style Manual for British conventions, The Editor’s Manual on comma placement with quotations, and general craft guidance from Writer’s Digest and the Center for Fiction.

Frequently asked questions

Does dialogue need its own paragraph?

Each new speaker needs a new paragraph. A single speaker’s words can share a paragraph with their own actions and narration. What you should avoid is two different characters speaking, or one acting while another speaks, in the same paragraph.

Do commas go inside or outside quotation marks in dialogue?

In American style, always inside: “Wait,” he said. In modern British fiction the comma before a tag usually goes inside as well: ‘Wait,’ he said. Some formal British styles put it outside, so follow your publisher’s or editor’s style sheet if you have one.

Should I use single or double quotation marks?

Double marks are standard in the United States and single marks are traditional in the UK. Many Australian publishers follow the British pattern, but both appear. Choose one and apply it consistently, with the other used for quotes inside dialogue.

How do I format dialogue in a story when one person speaks for several paragraphs?

Begin each paragraph with an opening quotation mark, but leave the closing mark off every paragraph except the last. That tells the reader the same character is still speaking.

How do I write engaging dialogue rather than flat dialogue?

Give both characters a goal and put those goals in tension. Cut small talk, let subtext carry the emotion, and read the scene aloud. Short exchanges and interruptions add energy, while a well-placed silence or action beat adds weight.

Is it okay to break dialogue rules?

Some literary authors drop quotation marks altogether, and it can work when it is deliberate and consistent. For commercial genre fiction, readers generally expect conventional formatting, so break a rule only when you know why.

Clear mechanics let readers stop noticing the page, and good craft keeps them turning it. Get the paragraphing and punctuation consistent first. Then give every exchange a job, and dialogue becomes one of the strongest tools in your book.
