How to Write Better Dialogue in Fanfiction: Tags, Action Beats, and Formatting

You’ve written the fic, your characters are bantering, flirting, bickering, trauma-dumping, all the good stuff… and then you pause and think:
“Wait. Is this dialogue actually readable? Or did I just invent a brand‑new way to abuse commas?”

Good news: dialogue in fanfiction doesn’t have to be “perfectly literary” to work. But it does need to be clear, consistent, and easy on the eyes. In this article, we’ll look at how to write better dialogue in fanfiction using three big tools in your toolbox: dialogue tags, action beats, and formatting.

First of all...

Writing dialogue is often the most fun part of fanfiction. You’re playing with characters you love, putting them in ridiculous situations, and letting them talk it out.
The problem is that messy tags and confusing formatting can turn great character voice into a wall of text people skim past instead of going feral and kicking their feet about.

This guide walks through:

You don’t have to follow everything rigidly (this is fanfic, you can and should be creative) but having a solid base makes your “rule breaking” intentional instead of accidental.

What even is a dialogue tag?

A dialogue tag is the little bit after (or before) quotation marks that tells us who’s speaking and how.
Classic examples: “said”, “asked”, “yelled”, “whispered”.

Very basic pattern:

“I’m stealing your fries,” she said.

That “she said” is your dialogue tag. It attaches directly to the speech and helps readers keep track of who’s talking.

Some people swear by only using “said.” It’s invisible, it doesn’t draw attention to itself, and it keeps things clean. That’s valid!
Personally, using only “said” everywhere makes my brain itch. Sometimes you want a little more flavor to show mood or tension without writing a full paragraph of description.

Using Dialogue Tags Without Overdoing It

Let’s look at a quick, slightly cursed example:

“You did what?” said Alex.
“It was an accident,” said Sam.
“You set the kitchen on fire,” said Alex.
“Okay, a small accident,” said Sam.

Technically correct. Also: repetitive, flat, and a bit boring.

Now tweak the tags:

“You did what?” demanded Alex.
“It was an accident,” muttered Sam.
“You set the kitchen on fire,” Alex insisted.
“Okay, a small accident,” Sam argued.

Better! We immediately get a sense of tone: demand, mutter, insist, argue. You don’t want to replace every single “said” (that gets exhausting), but sprinkling in a few specific tags gives your dialogue more life.

Quick tips:

What Are Action Beats?

Action beats are the little snippets of description that sit next to the dialogue and show what your character is doing while they talk.

Example:

“You set the kitchen on fire again.” Alex folded their arms and stepped in front of the stove.

No “said” needed. The action makes it clear who’s speaking, and it also gives us body language and mood.
A warning: be careful. In the example, if Alex wasn't speaking, we risk getting lost. Always make sure the speaker is super clear!

You can combine action beats with dialogue tags, but you don’t have to. Sometimes the action itself does all the heavy lifting.

Mixing Tags and Action Beats

Here’s a plain version:

“You’re late,” said Emily.
“Traffic,” said Crowley.
“You can teleport,” said Emily.

Now with beats:

“You’re late.” Emily checked the time on her phone for the third time.
“Traffic.” Crowley shrugged, sunglasses still on despite being indoors.
“You can teleport.” Emily stared.

We didn’t use a single “said,” and yet it’s crystal clear who is speaking. The action beats paint a picture, show personality, and slightly roast Crowley, which is always a bonus lmao

When to use action beats:

Common Dialogue Tag vs Action Beat Mistakes

Let’s go through a few patterns that fanfic writers trip over all the time.

1. Using Action Verbs as Dialogue Tags

❌ Incorrect:

“Hello,” she walked away.

“Walked” is not a way of speaking, it’s an action. That makes it an action beat, not a dialogue tag.

✅ Correct options:

“Hello,” she said, and walked away.
“Hello.” She walked away.

2. Capitalization After the Quote

If what follows is a dialogue tag, keep it lowercase.

✅ Correct:

“Don’t touch that,” he said.
❌ Incorrect:
“Don’t touch that,” He said.

If what follows is an action beat (a full new sentence), you capitalize:

✅ Correct:

“Don’t touch that.” He slapped her hand away from the button.

3. Comma vs Period Before the Tag

If a dialogue tag follows, you usually end the dialogue with a comma (or ? / !), not a period.

✅ Correct:

“I’m fine,” she said.
“You did what?” he asked.
❌ Incorrect:
“I’m fine.” she said.
“You did what?” He asked.

If an action beat follows, the sentence is done, so you use a period:

✅ Correct:

“I’m fine.” She wiped at her eyes anyway.

Formatting Dialogue for Readability

This is the part that makes readers love you: formatting that doesn’t hurt.

New Paragraph, New Speaker

Every time the speaker changes, start a new paragraph. This is non‑negotiable if you want people to follow your conversations without re-reading everything twice.

✅ Good:

“You’re late,” Emily said.
“No, you’re just early,” Crowley replied.
“We said six,” she insisted.

All three lines are separate because three different people are talking.

Keep Punctuation Inside the Quotes

In English dialogue formatting, punctuation usually lives inside the quotation marks.

✅ Correct:

“I brought snacks,” she said.
❌ Incorrect:
“I brought snacks”, she said.

Don’t Stuff Everything into One Paragraph

Big blocks of text + long dialogue + multiple speakers = instant scroll‑away.
Break things up with action beats, thoughts, or small reactions.

✅ Reader-friendly:

“Listen,” Emily started, “I know this sounds insane.”
Crowley arched an eyebrow. “You say that like it’s new.”

Two small paragraphs. Easy to read. Easy to scan. No eye strain.

“Show, Don’t Tell” with Dialogue

Dialogue is a great place to show emotions instead of listing them like a grocery receipt.

Telly version:

“I’m sad and disappointed,” she said sadly.

Showing through action and subtext:

“It’s fine,” she said. She folded the ticket in half, then in half again, until it was a crumpled ball in her fist.

The second example doesn’t say she’s sad. You feel it anyway.

Small Editing Checklist for Dialogue

When you’re revising your fanfic, try scanning your dialogue with questions like:

If the answer is “ehhh not really” to most of these, that’s fine. That’s exactly what editing is for.

A Little Help from a Tool

If all of this sounds like a lot to keep in your brain while also wrangling plot, canon, and fourteen side characters… same.

That’s why the tiny gremlin dev part of my brain built a thing: The Dialogue Thing.
Drop your text in and it flags:

A few important bits:

You still make the final decisions; the tool just points at the messy bits and goes “hey, maybe fix this.”

Conclusion

Writing dialogue in fanfiction is already hard work—you’re juggling canon, vibes, character voice, and a posting schedule that definitely did not ask your opinion. Getting comfortable with dialogue tags, action beats, and clean formatting makes that work pay off so much more. Your scenes become easier to follow, your jokes land better, and your emotional moments hit harder instead of getting lost in punctuation chaos.

Use this guide as a checklist next time you edit a chapter:

And if you want a little extra help catching the stuff your eyes now auto‑ignore, you can always paste your fic into The Dialogue Thing and let it highlight the chaos for you—so you can focus on the fun part: making your characters suffer in increasingly creative ways.
