How to Write a Book: A Step-by-Step Guide for First-Time Authors (2026 Guide)

How do you choose what to write about?

Choose an idea you care about enough to live with for many months, and that a specific reader would want to read. For fiction, that usually starts with a character who wants something and a problem standing in the way. For non-fiction, it starts with a reader’s problem you can genuinely help solve, ideally one you have solved yourself or know well.

Test the idea by writing it in one or two sentences: who the book is for, what happens or what they will gain, and why it matters. If you cannot do that, refine the idea before you start. A clear premise saves weeks of drifting later. If you are stuck between ideas, pick the one you would still be excited about in month four, when the novelty has worn off.

Decide your genre or category at this stage too. Readers arrive with expectations, and knowing them early shapes length, structure and tone. Read three or four recent, successful books in that space as a reader first, then again as a writer, noting how they open, how long the chapters are and how they end.

Do you need to plan before you write?

Some planning helps almost everyone. At minimum, know your main character or core message, roughly how the book begins, and where it ends. Knowing the ending gives every scene a direction, even if the route changes along the way.

Planners outline chapter by chapter, which turns a huge project into a list of manageable pieces. Discovery writers use a light sketch of the major turning points and find the rest as they go. Neither is wrong. The usual trade-off is that heavy planning costs less rewriting later, while discovery tends to feel more alive but often needs a bigger structural revision.

If you are unsure which you are, try a middle route: write a one-page outline of the beginning, the middle turning point, the lowest moment and the ending, then start drafting. For non-fiction, list the chapters as the questions your reader needs answered, in the order they will ask them. Our guide to outlining a novel covers proven structures in detail.

How long will it take, and how do you build a writing habit?

Books get written through consistency, not inspiration. The arithmetic is simple: divide your target word count by the words you can write per day or week. At 500 words a day, a 90,000-word draft takes about 180 writing days, roughly six months if you write every day. At 1,000 words a day it is about three months. Most first-time authors write fewer days than they plan, so build in slack.

Choose a target you can hit on a bad day, not a good one. A small number you always hit beats a big one you abandon.

• Write at the same time and place each day so it becomes routine.
• Track your word count somewhere visible. Watching the total grow is motivating.
• Protect the session: phone away, internet off if you can.
• Stop mid-sentence or mid-scene so tomorrow’s start is easy.
• Treat a missed day as a missed day, not a failed project. Start again the next one.

If you are short of time, small daily sessions still add up. Our guide on building a writing habit goes deeper on routines, and the Words Per Day Calculator will turn your deadline and word count into a daily target.

How do you get through the middle and finish the first draft?

The most important rule of a first draft is to finish it. Resist the urge to rewrite the opening chapters again and again, which is where many books stall for good. When you notice a problem, leave a short note in brackets, such as [fix timeline here], and keep moving forward.

The middle is where most people quit, because the excitement of the idea has faded and the end is not yet in sight. Ways through it: write the scene you are most looking forward to next, even out of order; ask what the worst thing is that could happen to your character now; or in non-fiction, return to the reader’s question and answer the next one. If you are properly blocked, our guide to overcoming writer’s block has practical fixes.

A first draft is supposed to be rough. Its job is to get the whole story or argument onto the page so you have something real to improve. You will know it is finished when it has a beginning, middle and end, even if parts are thin. Revision is where a book becomes good, and it cannot begin until the draft exists.

How long should your first book be?

Length depends on genre and readers’ expectations. Most adult novels fall roughly between 70,000 and 100,000 words, with some genres, such as fantasy, running longer and others, such as cosy or category romance, often shorter. Non-fiction varies far more: many practical books are shorter than novels, because readers want the answer, not padding.

Do not write to hit a number for its own sake. Write the story or argument the book needs, then compare against your genre once the draft exists. The Chapter Length Calculator can help you split a target word count into chapters, and our guide to novel word counts by genre has typical ranges.

If you are unsure whether you can sustain a long book, a shorter first project is a perfectly sensible choice. Finishing something small teaches you more about your process than abandoning something large.

How do you revise a book?

Let the draft rest for a few weeks if you can, then read it as a reader would, ideally in one or two sittings and on a different device or printed out. Make notes without fixing anything yet. You are looking for what is missing, slow or confusing.

Revise in layers. First the big picture: structure, pacing, character arcs, and whether each chapter earns its place. Then scenes and paragraphs. Finally sentences, word choice and typos. Working in this order stops you polishing a chapter you later cut.

Get outside feedback before you polish every line. Beta readers from your target audience, or a professional editor, can spot problems you cannot see from the inside. It is far cheaper to fix structure before line editing than after. If you are unsure which kind of editor you need, see our guide to developmental editing versus copyediting, and use the Editing Cost Estimator to budget.

What happens after the book is written?

Once revised, a manuscript normally goes through professional editing and proofreading. Then you choose a path: submit to literary agents for traditional publishing, or self-publish, which means preparing a cover, formatting the interior and uploading to retailers such as Amazon KDP. Our guide to publishing a book compares the routes.

If you use AI tools anywhere in your process, you stay responsible for the quality, accuracy and originality of the final text, and retailers have their own disclosure rules that can change, so check them before you publish. CruxOne is a browser-based AI publishing platform with a free plan, covering writing and editing help through to formatting and publishing to Amazon KDP and other stores.

Whichever path you choose, start thinking about readers early. A simple author website and email list, begun while you write, means you will have people waiting when the book comes out.

Frequently asked questions

How long does it take to write a book?

It depends on your pace. At 500 words a day, a 90,000-word draft takes about six months, plus time for revision and editing. Many first books take a year or more in total.

How many words should my first book be?

Most adult novels run about 70,000 to 100,000 words, depending on genre. Non-fiction varies more with the topic, and shorter is often fine.

Should I edit as I write?

Usually not. Finish the first draft, then revise. Constantly rewriting early chapters is a common reason books never get finished.

Do I need to outline my book?

Not strictly, but some planning helps almost everyone. Even a one-page outline of the main turning points gives you direction.

What should I do after finishing my first draft?

Let it rest, revise it in layers, get feedback from beta readers or an editor, then have it edited and proofread before you query agents or self-publish.
