How to Outline a Novel: Three Methods, Step by Step

To outline a novel, write your premise in two sentences, then sketch the story in three acts. Add the major turning points (beats), and break those beats into chapters with one clear change per chapter. You can stop at whichever level of detail lets you start drafting with confidence.

Below are six steps you can follow in order, three methods you can mix, a worked example outline, and advice for deciding how much to plan in the first place.

What you need before you outline a novel

You don't need much, but have these ready before you start:

• A story idea with a person in it. "A haunted lighthouse" is a setting. "A ferry pilot who finds her dead father's secret logbook" is a story.
• A rough genre. Genre sets reader expectations about pace, ending and length. A cozy mystery and an epic fantasy need very different outlines.
• A target length. This tells you roughly how many chapters to plan. If you're unsure, see how many words are in a novel for typical ranges by genre.
• Somewhere to write that's easy to rearrange. Index cards, a spreadsheet or a document with headings all work. You will move scenes around, so pick something that makes that painless.
• A few hours. A first-pass outline can be done in an afternoon. You'll revise it as you draft.

If you haven't settled on the idea yet, start with how to write a book and come back here.

Step 1: Turn an idea into a premise

Write two sentences. The first names your main character, what they want, and what stands in the way. The second names the stakes and, if possible, a deadline.

Here is the example we'll outline through the rest of this article:

Mara, a ferry pilot on a small northern island, finds her late father's logbook listing night crossings that never appeared in any official record. She has until the autumn storms close the route to learn who he was carrying, before the person who paid for those crossings finds her first.

A good premise gives you the engine of the whole outline. You can see the goal (find out who he carried), the obstacle (someone dangerous who wants it hidden), the deadline (the storms) and the personal stakes (her father's real identity).

If you can't write these two sentences yet, more outlining won't help. Spend your time here first.

Step 2: Choose an outlining method

There are three common methods. They aren't rivals. Most writers use them as layers, going from broad to detailed.

Method	What you produce	Detail level	Best for
Three-act structure	Beginning, middle and end in a few paragraphs	Low	Finding the shape of the story fast
Beat sheet	10–15 turning points in order	Medium	Fixing pacing and saggy middles
Chapter-by-chapter	A line or paragraph per chapter	High	Drafting quickly and keeping track of subplots

Start with three acts. Add beats if you want more structure. Go to chapter level if you like to know exactly what you're writing each day. The steps below walk through all three on the same example.

Step 3: Outline your novel in three acts

Three-act structure splits the story into setup, confrontation and resolution. A common rule of thumb is that Act One takes roughly the first quarter, Act Two the middle half, and Act Three the final quarter. Treat that as a guide, not a law.

Write a short paragraph for each act.

Act One: Setup

Show the character's normal life and the problem underneath it. End the act with an event that pushes them into the story for good.

Example: Mara runs the island ferry and avoids thinking about her father's death. While clearing his house, she finds the logbook. When she asks the harbourmaster about one of the dates, he lies to her, and that night someone searches her cabin. She decides to trace the crossings.

Act Two: Confrontation

The character pursues the goal, the opposition pushes back, and things get worse. Somewhere near the middle, something changes the meaning of the whole story.

Example: Mara follows the logbook's coordinates and learns her father ferried people off the island secretly. At the midpoint she discovers he was being paid by the family who owns half the island, and that the last crossing in the book was the night he died. Her allies start to pull away. By the end of the act, she has lost the logbook and her best friend has been hurt.

Act Three: Resolution

The character faces the main conflict directly, using what they've learned, and the story's central question is answered.

Example: With the storms arriving, Mara makes one final night crossing herself to draw the family's son into the open. She gets his confession on record. She learns her father was helping people escape the family, not working for them, and she chooses to stay and keep the ferry running.

At this point you have a usable outline. Some writers stop here and start drafting.

Step 4: Build a beat sheet for your novel

A beat sheet breaks the acts into specific turning points. The best-known version comes from Blake Snyder's Save the Cat!, a screenwriting book that many novelists have adapted. You don't need to follow any system exactly. These are the beats most stories share:

1. Opening image: a snapshot of the character's life before the story.
2. Inciting incident: the event that disrupts normal life.
3. Debate: the character hesitates or resists.
4. Break into Act Two: they commit to the goal.
5. Fun and games / exploration: the promise of the premise plays out.
6. Midpoint: a reveal or reversal that raises the stakes.
7. Bad guys close in: pressure builds, inside and out.
8. All is lost: the lowest point.
9. Dark night: the character reckons with what they've learned.
10. Break into Act Three: a new plan, often built on the theme.
11. Finale: the main confrontation.
12. Final image: a mirror of the opening that shows the change.

Write one or two sentences per beat for your story. If a beat is hard to fill, that usually points to a real gap in the plot, which is exactly what you want to find before drafting rather than 40,000 words in.

Step 5: Outline your novel chapter by chapter

Now spread the beats across chapters. Give each chapter one job: something must change by the end of it. That change might be new information, a decision, a loss or a shift in a relationship.

Here is a worked example for the ferry novel, planned at 16 chapters. A real outline might have more or fewer.

Ch.	Act	Beat	What happens	What changes
1	One	Opening image	Mara runs the morning ferry and dodges questions about her father.	We see her closed-off routine.
2	One	Inciting incident	Clearing his house, she finds the logbook of unrecorded night crossings.	She has a mystery she can't ignore.
3	One	Debate	She asks the harbourmaster about a date; he lies. Her friend Jonah tells her to let it go.	She suspects a cover-up.
4	One	Break into Act Two	Her cabin is searched. She hides the logbook and plots the first coordinates.	She commits to investigating.
5	Two	Exploration	She visits a cove from the log and finds signs of a hidden landing.	The crossings were real.
6	Two	Exploration	An elderly islander admits her father "took people away" at night.	Her father had a secret life.
7	Two	Subplot	Jonah agrees to help; their old friendship resurfaces.	She has an ally.
8	Two	Midpoint	Bank records show payments from the Carrow family. The final crossing was the night he died.	The mystery becomes a possible murder.
9	Two	Bad guys close in	The Carrows offer to buy the ferry. She refuses.	The opposition goes public.
10	Two	Bad guys close in	Her ferry licence is suspended over a "safety complaint".	She loses her livelihood.
11	Two	All is lost	The logbook is stolen and Jonah is injured on the dock.	She's alone, without evidence.
12	Two	Dark night	She rereads her father's letters and spots a pattern in his notes.	She realises he was protecting people from the Carrows.
13	Three	Break into Act Three	She plans one last crossing before the storms to draw out the Carrow son.	She has a new plan.
14	Three	Finale	Night crossing in rising weather; confrontation on board.	She gets his confession on record.
15	Three	Finale	The Carrows' hold on the island breaks; the harbourmaster comes clean.	The truth is public.
16	Three	Final image	Mara runs the morning ferry again, this time talking openly about her father.	Mirror of chapter 1, showing her change.

Notice the last column. If you can't fill in "what changes" for a chapter, that chapter is probably filler, or two chapters are doing the same job and should be merged.

To guess how long the finished book will be in print, divide your target word count by your chapter count for a rough words-per-chapter figure, then use the book page count calculator once you have a draft.

Step 6: Test your outline before you start writing

Run these checks before you draft:

• Read only the "what changes" column. It should read like a summary of the story. If it doesn't, you have chapters without purpose.
• Check the midpoint. It should change the meaning of the goal, not just add another obstacle.
• Check cause and effect. Each major event should happen because of the one before, not just after it.
• Track subplots. Give each subplot a beginning, a turn and an ending. If Jonah disappears for six chapters, readers will notice.
• Check the ending against the opening. The final image should show how the character has changed.

If you plan to use AI to help draft, a detailed chapter outline matters even more, because it keeps the generated chapters pointed in one direction. Inkora's AI novel writer builds an editable "book bible" from your brief, including the premise, characters, a style guide and a chapter-by-chapter outline, so you can adjust the plan before any chapter is written.

Plotting versus pantsing your novel

"Pantsing" means writing by the seat of your pants, discovering the story as you draft. "Plotting" means outlining first. Most writers sit somewhere in between.

Plot more if:

• You're writing in a genre with strong expectations, such as mystery, thriller or romance, where clues, twists or the relationship arc need to land at the right moments.
• You've abandoned drafts before because you got lost in the middle.
• You're writing a long book with several viewpoints or subplots.
• You have limited writing time and want to know exactly what to write in each session.

Pants more if:

• Planning drains your interest in the story, and you only find out what you think by writing.
• The book is character-driven and the plot grows out of how people react to each other.
• You're comfortable doing heavy structural revision after the first draft.

A middle path that works for many writers: outline the three acts and the midpoint, then pants your way between them. You know where you're going, but not every step of the route. Some writers also pants a messy first draft, then outline that draft to find its structure before revising.

There's no correct answer. Try one approach on one book and notice where you got stuck.

Common problems and fixes

The middle sags. This is the most common outlining problem. Strengthen the midpoint so it changes the goal or the stakes, then make sure every chapter in Act Two raises pressure. Cut chapters where the character only gathers information without consequences.

The outline feels rigid and you've lost interest. Your outline is too detailed for how you work. Delete the chapter-level notes and keep only the beats. Let yourself discover the scenes.

Your characters won't do what the outline says. Usually this means the outline doesn't match the characters' motives. Ask what this person would actually do in the situation, then adjust the plot to follow, not the other way around.

You've drifted from the outline mid-draft. That's normal. Stop and update the outline from where you are now, rather than forcing the story back onto the old plan. The outline is a tool, not a contract.

The ending feels unearned. Trace the final confrontation backward. The skill, knowledge or choice that wins the day should be set up in Act One or Two. If it isn't, plant it earlier.

You keep outlining and never start writing. Set a deadline. Once you have the premise, three acts and a midpoint, start chapter one. You'll learn more from 5,000 drafted words than from another week of planning.

Subplots vanish or pile up. Add a column to your outline table for each subplot and mark which chapters touch it. Gaps and clusters become obvious at a glance.

Start with two sentences, build to three acts, and add beats and chapters only as far as they help you write. A good outline answers "what happens next?" so your drafting time goes into the words themselves. When the draft is done, the next stage is covered in how to self-publish a book.
