How to Write Dialogue in a Book: Rules and Examples

Dialogue has two jobs: it has to sound like real people, and it has to follow the punctuation rules readers expect. This guide covers both, with a before-and-after scene and a short quiz at the end. The rules below follow US style (Chicago Manual of Style), with the UK differences shown. If your draft is finished and the dialogue still feels stiff, line editing works on exactly this, sentence by sentence. Writing about your own life? See dialogue in a memoir for remembered conversations. For the rest of the process, see writing a book, step by step.

Dialogue punctuation rules at a glance

Dialogue punctuation comes down to a few patterns. Here they are, each with an example from our invented mystery, Ten Days in Kestrel Bay.

New speaker, new paragraph. Every time someone else speaks, start a new paragraph. A character’s actions can share their paragraph, which tells the reader who’s talking without a tag.

Long speeches. If one character speaks for more than one paragraph, leave off the closing quotation mark at the end of each paragraph except the last, and open each new paragraph with a quotation mark.

US and UK style. In the US, dialogue uses double quotation marks, with single marks for a quote inside a quote. British publishers often use single marks for dialogue and double marks inside them, though some UK publishers use double marks. In modern fiction on both sides of the Atlantic, commas and periods that belong to the dialogue go inside the closing mark. If you have a publisher, follow its house style.

Dialogue tags and action beats

A dialogue tag tells the reader who’s speaking: “she said,” “he asked.” An action beat does the same job by showing the speaker doing something.

• Use “said” for many of your tags. Readers skim past it, so the words stay in front. “Asked” works for questions.
• Use another verb only when it adds information. “Whispered” or “shouted” tells the reader how it sounded. Verbs that aren’t ways of speaking, such as “she smiled” or “he laughed,” work better as action beats.
• Use action beats to add movement. “Ellis looked away. ‘I wasn’t there.'” hints at a lie without saying so.
• Drop tags when it’s clear. In a quick exchange between two people, you can leave tags off for a few lines. Add one back before the reader loses track.
• Go easy on adverbs. “She said angrily” tells the reader what the line should already show. Let the words, or an action, carry the anger.

Make dialogue sound real

Good dialogue sounds like people talking, without the parts of real talk that bore a reader.

• Cut small talk. Skip greetings, weather and “How are you?” unless the moment depends on them. Enter a conversation late and leave it early.
• Let people avoid answers. Characters rarely say exactly what they mean. A dodged question can say more than a confession. This unspoken layer is often called subtext.
• Give each character a voice. One speaks in short sentences, another rambles; one swears, another never does. Distinct speech and distinct character names both help readers track who’s talking.
• Use dialect lightly. A few word choices and the rhythm of a sentence suggest an accent better than spelling every word phonetically, which tires readers.
• Don’t explain what both characters know. “As you know, your father ran this harbor for thirty years” is a line for the reader. People rarely say that to someone who already knows.
• Read it aloud. If you stumble over a line, a reader probably will too.

One scene, before and after

Here’s a short exchange from Ten Days in Kestrel Bay, first flat, then revised. The same mystery runs through our guide to writing a fiction book.

What changed:

• The greetings are gone, and the scene starts at the conflict.
• “As you know” is gone. The reader can learn the father’s history elsewhere.
• Fancy tags and adverbs are gone. Pell’s actions show he’s avoiding her.
• Mara’s last line says she knows he’s lying, without anyone saying “lying.”

Texts, phone calls, thoughts and foreign words

These come up in many modern novels, and the main rule is to choose one style and use it every time.

• Text messages. Chicago’s style blog notes that texts in fiction are often set in italics, bold or a different font, and longer exchanges can be set apart from the text. Short texts can sit in the narrative with an action beat: Where are you? lit up her screen.
• Phone calls. Punctuate them like any dialogue. If the scene stays with one character, you can show only their side and let the reader infer the rest.
• Thoughts. Quotation marks are usually kept for speech. Thoughts can go in italics, or in plain text with a tag such as “she thought.” Chicago’s style blog treats italics as optional.
• Foreign words. Chicago italicizes non-English words a reader may not know in general writing, but its style blog leans toward regular type in fiction, with context carrying the meaning. Either way, stay consistent.

Dialogue mistakes to fix in revision

• Every line has a tag, so the page reads like a transcript.
• Characters say each other’s names in every line.
• Speeches run for paragraphs with no interruption or reaction.
• Everyone sounds the same.
• Dialogue explains things both characters already know.
• Punctuation changes from chapter to chapter.

When to get help

Help makes sense when you’ve revised your dialogue and it still doesn’t sound right.

• Your dialogue reads stiff or everyone sounds the same. A line edit works through your manuscript sentence by sentence, including voice, rhythm and tags. For fiction it is $310 for the first 10,000 words, then $0.031 a word.
• You only need punctuation and consistency checked. A copy edit fixes dialogue punctuation, capitalization and consistency, and comes with a style sheet. For fiction it is $240 for the first 10,000 words, then $0.024 a word.
• Not sure which? A $49 sample edit of up to 1,000 words shows you, and the $49 comes off your edit if you book within 60 days.

Dialogue questions authors ask

Do you use single or double quotation marks for dialogue?

In US English, use double quotation marks for dialogue and single marks for a quote inside it. British publishers often use single marks for dialogue and double marks inside, though some UK publishers use double marks too. In modern fiction, both styles put commas and periods that belong to the dialogue inside the closing mark. Pick one style and use it through the whole book.

Is it OK to use “said” every time?

Usually, yes. Readers skim past “said,” so it keeps attention on the words. Mix in “asked” for questions, a more specific verb when it tells the reader how a line sounded, and action beats to show who’s speaking. In a quick back-and-forth between two characters, you can drop tags for a few lines, as long as the reader can still follow who’s talking.

Do you start a new paragraph every time someone speaks?

Yes. Each time the speaker changes, start a new paragraph, even if the line is one word. A character’s actions and their dialogue can share a paragraph, which shows who’s speaking without a tag. If one character speaks for several paragraphs, leave the closing quote off each paragraph but the last, and open each new one with a quotation mark.

How do you write a text message in a novel?

There’s no single rule. Chicago’s style blog notes that texts in fiction are often set in italics, bold or a different font, and longer exchanges can be set apart like a block. Short texts can sit in the narrative with an action beat. Choose one style and use it for every text in the book, so readers can spot a message.
