How to Plan a Book
A complete guide to turning an idea into a workable structure, chapter plan, research system and writing roadmap
Planning a book does not mean deciding every sentence before writing. It means establishing enough clarity to understand what the book is about, who it is for, how it will develop and what must be completed. A sound plan reduces confusion, exposes weak areas early and gives the author a practical route from the first idea to the finished draft.

From Book Idea to Writing Roadmap
Use this guide to define the book, organise the material, plan the chapters, identify research needs and create a realistic route to the first draft.
1. What Is Book Planning?
Book planning is the process of deciding what the manuscript will contain, how the material will be organised and what work must be completed before and during drafting.
A plan may be brief or detailed. At minimum, it should help the author understand the book's central idea, intended reader, broad structure, research needs and likely progression.
Planning is not a contract that prevents discovery. It is a working map. The author may revise it as characters develop, research changes the argument or new material becomes necessary.
A useful book plan should answer:
- What is this book about?
- Who is it written for?
- What experience or result will it offer?
- What belongs in the book?
- What does not belong?
- How will the material progress?
- What research is required?
- How long might the manuscript be?
- How will the author complete it?
A plan should create direction, not paralysis.
The purpose of planning is not to predict every discovery that will occur during writing. It is to reduce preventable confusion and give the author a clear next step.
When planning becomes an endless substitute for drafting, it has stopped serving the book.
Planning Approaches
2. Does Every Writer Need a Book Plan?
Every writer needs some degree of direction, but not every writer needs the same level of detail.
Planning Before Drafting
Some authors work best when they define the major structure, chapters, characters or arguments before beginning.
- Reduces uncertainty
- Helps identify missing research
- Makes long projects easier to manage
- Supports complex plots or arguments
- May reduce major structural rewriting
Discovering Through Drafting
Other authors learn what the book is by writing scenes, chapters or exploratory material.
- Allows spontaneity
- May reveal unexpected character choices
- Can produce a natural voice
- May suit literary or reflective work
- Usually requires more structural revision later
3. How Much Planning Is Enough?
The appropriate level of planning depends on the type of book, the author's working method and the complexity of the material.
A legal thriller involving several timelines may require detailed planning. A reflective memoir may need a strong thematic structure but less scene-by-scene preparation. A practical nonfiction book usually benefits from a clear chapter architecture before drafting begins.
Use more detailed planning when:
- The book contains several timelines
- Multiple points of view are involved
- The plot depends on clues or revelations
- Historical accuracy is important
- The argument builds sequentially
- The subject requires extensive research
- Many chapters depend on earlier definitions
- The manuscript must meet a proposal or contract
Use a lighter plan when:
- The voice and experience are still being discovered
- The manuscript is intentionally exploratory
- The author already knows the material deeply
- A detailed outline reduces creative energy
- The book can be reorganised without damaging a complex chain of events
The Book Foundation
4. Establish the Book Before Planning the Chapters
Chapter planning becomes much easier once the fundamental decisions are clear.
Central Idea
State what the book is fundamentally about in one or two sentences.
Purpose
Define why the book needs to be written and what it seeks to accomplish.
Reader
Identify the primary person for whom the book is being written.
Promise
Determine what the reader will experience, understand or gain.
Scope
Decide which period, questions, subjects and events belong in the book.
Form
Confirm whether the work is a novel, memoir, guide, biography or another form.
Genre
Identify the conventions and expectations that shape the manuscript.
Structure
Choose the broad organisational pattern that will carry the material.
Completion Route
Set the schedule, research system and practical working method.
5. Define the Purpose of the Book
Purpose gives the manuscript direction. It explains what the author is trying to create, explore, reveal, argue or help the reader accomplish.
A novel may seek to explore loyalty under pressure. A memoir may examine how retirement changed the author's understanding of freedom. A practical book may help first-time authors prepare a professional manuscript.
Complete this sentence:
This book exists to help, show, explore, explain or reveal...
The answer should be specific enough to guide decisions. “To inspire people” is too broad. “To help mid-career professionals understand the emotional and practical consequences of early retirement” provides greater direction.
6. Identify the Intended Reader
A book written for everyone usually lacks sufficient precision for anyone. The author should identify the primary reader even when the book may later attract a broader audience.
Consider the reader's:
- Age
- Knowledge of the subject
- Professional or educational background
- Emotional situation
- Reason for choosing the book
- Expectations of tone and complexity
- Likely questions
- Available reading time
A book for beginners should not assume specialist knowledge. A book for professionals should not spend half its length explaining basic concepts. A young-adult novel should be written for teenage readers rather than merely contain teenage characters.
7. Define the Central Promise
The central promise describes what the book will deliver. It is closely connected to genre and reader expectation.
A mystery promises discovery. A thriller promises escalating danger. A romance promises that the central relationship will matter. A practical guide promises usable understanding or action.
Useful promise questions include:
- What will keep the reader turning pages?
- What question will the book answer?
- What change will occur?
- What emotional experience will the reader receive?
- What knowledge or method will the reader gain?
- What expectation must the ending fulfil?
The promise does not need to appear as a statement in the manuscript, but the structure should fulfil it.
8. Set the Scope and Boundaries
Many manuscripts become unmanageable because the author has not decided what the book will exclude.
A memoir does not need to contain every life event. A history book cannot explain every related political development. A novel should not include every possible character or subplot.
Define the boundaries of:
- Time period
- Geographical area
- Main characters or subjects
- Research depth
- Reader level
- Number of themes
- Number of points of view
- Likely word count
Material that does not belong in the current book can be preserved for an article, appendix, companion volume or future project.
Research Planning
9. Create a Research Plan
Research should support the book rather than delay it indefinitely.
Background Research
Establish the context, terminology, history and basic facts necessary to understand the subject.
Primary Sources
Identify interviews, records, diaries, letters, legal documents, archives or direct observation.
Secondary Sources
Use reliable books, articles, studies and expert interpretations to deepen understanding.
Verification
Create a list of names, dates, quotations, statistics and claims requiring confirmation.
Permissions
Note photographs, quotations, poems, letters or other material that may require permission.
Research Limits
Decide what information is necessary before drafting and what can be confirmed later.
10. Choose the Broad Structure
Structure is the organising principle that determines how the reader moves through the book.
The correct structure depends on the material. A chronological structure may suit biography. A problem-and-solution structure may suit practical nonfiction. A three-part transformation structure may suit memoir.
Common structures include:
- Chronological
- Thematic
- Problem and solution
- Question and answer
- Journey or transformation
- Three-act structure
- Five-act structure
- Alternating timelines
- Multiple points of view
- Case-study structure
- Step-by-step instructional structure
- Seasonal, geographical or institutional structure
The forthcoming TGEP guide to Book Structure will examine these models in greater depth.
Outline Development
11. Create a Working Outline
An outline records the order in which the material is expected to develop.
One-Sentence Book Description
State the central subject, character, conflict, question or result.
One-Paragraph Summary
Describe the beginning, development and destination of the book.
Part Structure
Divide the book into two to five major movements, phases or subject areas.
Chapter List
Give each chapter a working title and a specific function.
Chapter Notes
Record scenes, arguments, examples, research and transitions for each chapter.
Writing Tasks
Convert the outline into practical sessions, research tasks and deadlines.
12. Plan the Chapters
A chapter should perform a recognisable function. It may advance the plot, develop a character, introduce evidence, explain a concept, deepen a theme or move the reader into the next stage.
For each chapter, record:
- Working title
- Main purpose
- Opening situation or question
- Key scenes, arguments or evidence
- Change produced by the chapter
- Research still required
- Connection to the previous chapter
- Reason to continue to the next chapter
- Approximate word count
If two chapters perform the same function, they may need to be combined. If one chapter contains several unrelated purposes, it may need to be divided.
Fiction Planning
13. How to Plan a Novel
Fiction planning connects character, conflict, consequence and change.
Protagonist
Define who carries the main story, what the character wants and what they truly need.
Inciting Event
Identify the event that disturbs the existing situation and begins the main movement.
Central Conflict
Determine what prevents the protagonist from achieving the objective easily.
Escalation
Plan how obstacles, costs and consequences will increase.
Turning Points
Identify decisions or discoveries that change the direction of the story.
Climax
Define the decisive confrontation, decision or irreversible action.
Resolution
Decide what changes and what emotional or narrative promise is fulfilled.
Subplots
Include only subplots that deepen character, conflict or theme.
Scene Progression
Plan scenes around objectives, obstacles, change and consequence.
Nonfiction Planning
14. How to Plan a Nonfiction Book
Nonfiction planning should move the reader from a defined starting point to a clear understanding, conclusion or practical result.
Reader Problem
State the question, difficulty or need that brings the reader to the book.
Central Argument
Define what the author believes, proposes or seeks to demonstrate.
Evidence
Identify research, cases, examples, experience and authority supporting the book.
Learning Sequence
Arrange concepts so that later chapters build upon earlier understanding.
Practical Application
Decide where readers need examples, exercises, checklists or action steps.
Conclusion
Determine what the reader should understand or be able to do by the end.
15. How to Plan a Memoir
Memoir planning begins with selection. The writer must decide which period or experience belongs in the book and what deeper question connects the events.
Plan the memoir around:
- A defined period or relationship
- A central emotional question
- A beginning state
- A sequence of significant experiences
- Moments of decision or change
- The narrator's present understanding
- A meaningful ending point
The memoir should not become a complete record of everything that happened. Each scene should contribute to the central transformation or inquiry.
See the TGEP guide to How to Write a Memoir.
16. Plan the Characters
Characters should not be defined only by appearance, occupation or family role. Planning should identify desire, fear, contradiction, history and capacity for change.
For each major character, record:
- Role in the story
- Primary desire
- Immediate objective
- Fear or vulnerability
- Important past event
- Conflict with other characters
- What the character hides
- What the character misunderstands
- How the character may change
- Distinctive speech or behaviour
Character planning should remain flexible. The writer may discover deeper motives during drafting, but early clarity prevents characters from existing only to serve plot mechanics.
17. Plan the Plot as a Chain of Consequences
Plot is not simply a list of events. It is a sequence in which actions, decisions and discoveries produce consequences.
A useful plot plan should show why one event leads to another. “This happens, and then this happens” is weaker than “because this happens, the character must do this, which creates a new problem.”
Test each major plot point:
- What causes it?
- Who makes the decision?
- What changes?
- What new problem appears?
- What becomes more difficult?
- What information is revealed or concealed?
- Why can the character not return to the earlier situation?
18. Plan the Setting and World
Setting includes place, time, culture, weather, institutions, social rules and physical conditions. It should influence the story rather than function as decoration.
Plan important details such as:
- Geographical location
- Historical period
- Season and climate
- Social and cultural expectations
- Economic conditions
- Institutions and power structures
- Travel time and physical distance
- Language and local terminology
- Rules governing an invented world
Historical and speculative fiction require particular attention to internal consistency and research.
Continuity Planning
19. Create a Timeline
A timeline prevents contradictions and helps the author control pace.
| Timeline Field | What to Record | Why It Matters |
|---|---|---|
| Date or Day | The exact or relative time of each major event | Prevents impossible sequences |
| Character Age | Ages at important past and present events | Maintains biographical continuity |
| Location | Where each character is during the event | Prevents unexplained movement |
| Knowledge | What each character knows at that point | Protects mystery and revelation |
| Research Event | Historical, legal or public events relevant to the book | Supports factual accuracy |
| Emotional State | How the event affects the character or narrator | Supports believable development |
20. Choose the Point of View
Point of view determines who tells the story, what the reader can know and how closely the reader experiences events.
Common options include:
- First-person singular
- First-person multiple narrators
- Third-person limited
- Third-person multiple viewpoints
- Third-person omniscient
- Second person
- Retrospective memoir narration
Before choosing multiple viewpoints, ask whether each narrator contributes essential information, conflict or perspective. Additional viewpoints create complexity and should not be added only to avoid difficult scene construction.
21. Identify the Themes Without Forcing Them
Themes are the larger questions or ideas explored through the book. They may include identity, ambition, belonging, justice, loyalty, grief, freedom, power, faith or memory.
The author may identify likely themes during planning, but the manuscript should not become a lecture explaining them.
Theme should emerge through:
- Character choices
- Conflict
- Consequences
- Repeated images or situations
- Contrasting viewpoints
- The structure of the argument
- The relationship between beginning and ending
Planning themes helps the writer recognise coherence without requiring every scene to announce the book's meaning.
22. Set a Working Word-Count Target
A target helps convert the book into manageable parts. It is not a guarantee of final length.
If the target is 80,000 words and the plan contains 20 chapters, the average chapter might be approximately 4,000 words. Some chapters will naturally be shorter or longer.
Use word-count planning to estimate:
- Total manuscript length
- Number of chapters
- Average chapter size
- Weekly progress
- Likely completion time
- Whether the project is becoming too broad
Genre expectations matter, but the manuscript should not be padded merely to reach a number.
Completion Planning
23. Create a Realistic Writing Schedule
A plan becomes useful when it is connected to time and action.
Estimate the Draft Length
Choose a reasonable working target based on genre and scope.
Assess Available Time
Use the time that actually exists rather than the time you wish existed.
Choose a Weekly Target
Set words, scenes, chapters or focused hours as the measure.
Add Research Time
Separate research, drafting and revision tasks where possible.
Include Buffer Time
Illness, work, family obligations and difficult chapters will affect progress.
Review Monthly
Adjust the plan based on actual progress rather than abandoning it completely.
Plan the Ending
Reserve time to complete the final section rather than endlessly revising the opening.
Separate Revision
The first-draft deadline should not be confused with the publication-ready date.
Working Systems
24. Choose Simple Planning Tools
The best tool is the one the author will continue using.
Notebook
Useful for early ideas, diagrams, character notes and portable observation.
Word Document
Suitable for outlines, chapter summaries, research notes and working drafts.
Spreadsheet
Useful for timelines, scenes, chapter length, research tracking and continuity.
Index Cards
Allow scenes or chapters to be moved physically while testing structure.
Writing Software
May help organise large manuscripts, but should not become a substitute for writing.
Cloud Folder
Keeps drafts, research and supporting material organised and backed up.
25. Build a Clear Project Folder
A well-organised folder prevents lost research, duplicate drafts and uncertainty about which file is current.
A practical folder may include:
- 01 Book Concept
- 02 Outline
- 03 Character or Subject Notes
- 04 Research
- 05 Source Records
- 06 Draft Chapters
- 07 Complete Drafts
- 08 Feedback
- 09 Revision Notes
- 10 Submission Materials
Use dates or version numbers in filenames. Avoid names such as “Final,” “Final New,” “Final Corrected” and “Final Last.”

TGEP Editorial Insight
A strong book plan does not remove discovery from writing. It protects the writer from avoidable confusion. The most useful plan tells the author what the book is trying to achieve, what belongs in it, how the material will develop and what practical work must happen next.
Frequently Asked Questions
Questions Authors Ask About Planning a Book
Practical answers to common planning and outlining concerns.
How do I begin planning a book?
Begin with the central idea, intended reader, purpose, genre and book promise. Then define the scope and create a broad structure before planning individual chapters.
Do I need to plan the whole book before writing?
No. Some writers use detailed plans while others use broad outlines. You should have enough direction to understand the book's movement and your next task.
What should be included in a book plan?
A useful plan includes the concept, reader, purpose, promise, scope, genre, structure, chapters, research needs, word-count target and writing schedule.
What is the difference between a plan and an outline?
A book plan covers the entire project, including reader, purpose, research, schedule and structure. An outline focuses mainly on the order and contents of the manuscript.
Should I plan every chapter?
It is useful to give each chapter a purpose and broad content. Detailed scene-level planning is optional and depends on the writer and type of book.
How many chapters should a book have?
There is no fixed number. The number should arise from the material, structure, genre and intended length rather than an arbitrary rule.
Can I change the plan while writing?
Yes. A plan is a working document. It should be revised when the manuscript reveals a stronger direction or research changes the author's understanding.
Should I know the ending before I start?
Knowing the likely ending can improve direction and foreshadowing, but the exact ending may change during drafting. At minimum, understand the type of resolution the book requires.
How long should book planning take?
Planning may take a few days or several months depending on complexity and research. It should continue only as long as it meaningfully supports the manuscript.
Can I plan a book in a notebook?
Yes. A notebook, word processor, spreadsheet, index cards or specialist writing software can all work. Use the simplest reliable system for your needs.
What if planning makes me lose interest?
Reduce the level of detail. Keep the central direction and major turning points, then allow discovery during drafting.
What if I keep changing the plan?
Distinguish useful development from avoidance. Choose a direction, write a substantial section and review the plan at defined intervals rather than changing it after every difficult session.
Should fiction and nonfiction be planned differently?
Yes. Fiction planning usually centres character, conflict and consequence. Nonfiction planning centres reader need, argument, evidence and learning sequence.
Can a publisher help plan my book?
Some publishers and developmental editors may help shape a manuscript, but the author should still arrive with a clear concept, purpose and body of material.
