Ask ten authors how long it took to write their book and you'll get answers from six weeks to ten years. Both can be true, because "writing a book" covers a first draft, months of revising, and everything that happens before it reaches a reader.
This guide breaks down how long it takes to write a book in realistic numbers. You'll get a table of drafting time by length and daily word count, then the full timeline from idea to launch. Every number here is an estimate to plan with, not a promise.
How long does it take to write a book, by words per day?
The fastest way to estimate your first draft is simple math: total words divided by words per day. The table below assumes you write five days a week and take weekends off.
| Draft length | 500 words/day | 1,000 words/day | 2,000 words/day |
|---|---|---|---|
| 30,000 words | ~12 weeks | ~6 weeks | ~3 weeks |
| 50,000 words | ~20 weeks | ~10 weeks | ~5 weeks |
| 70,000 words | ~28 weeks | ~14 weeks | ~7 weeks |
| 90,000 words | ~36 weeks | ~18 weeks | ~9 weeks |
These are first-draft estimates only. They assume you have an outline and don't stop to edit, and real life will add some missed days. Add 20 to 30 percent as a buffer if you have a demanding job or family.
Key takeaway: At 500 words a day on weekdays, a 50,000-word draft takes about five months. At 1,000 words, about ten weeks. The daily number matters less than hitting it consistently.
How many words a day is realistic?
It depends on your schedule and how well you know the material. For people writing around a full-time job, 500 to 1,000 words a day is a common, sustainable range, roughly 30 to 60 minutes of focused drafting once you have an outline.
Full-time writers on familiar subjects can often manage 2,000 or more. Very few people sustain much beyond that for months without the quality dropping.
How long are books, by type?
Your total word count sets the size of the job. Typical lengths vary by category. Literary agent Rachelle Gardner suggests these targets for authors seeking a traditional deal:
- General nonfiction: about 70,000 to 80,000 words
- Memoir: about 75,000 to 95,000 words
- Self-help: about 40,000 to 55,000 words
Self-published books are often shorter, especially practical business books. Fiction lengths vary widely by genre, so check books on the same shelf as yours.
Here's how that translates into drafting time, using the same five-days-a-week assumption.
| Book type | Typical length | First draft at 500/day | First draft at 1,000/day |
|---|---|---|---|
| Short business or how-to book | 30,000–45,000 words | ~3–4.5 months | ~6–9 weeks |
| Self-help | 40,000–55,000 words | ~4–5.5 months | ~8–11 weeks |
| General nonfiction | 70,000–80,000 words | ~7–8 months | ~14–16 weeks |
| Memoir | 75,000–95,000 words | ~7.5–9.5 months | ~15–19 weeks |
Research-heavy books take longer than these numbers suggest, because time spent reading and interviewing isn't drafting time. History, science and investigative books can take years.
How long does the full process take, from idea to launch?
The first draft is usually less than half the total time. Here's a realistic timeline for a self-published nonfiction book of about 50,000 words, written part-time. All durations are estimates.
| Stage | What happens | Typical time (estimate) |
|---|---|---|
| 1. Planning | Define the idea and reader, check comparable books, build the outline | 2–6 weeks |
| 2. First draft | Write the full draft from the outline | 10–20 weeks |
| 3. Rest and self-revision | Step away, then fix structure, gaps and clarity | 4–10 weeks |
| 4. Beta readers | Readers review the draft and send feedback | 3–6 weeks |
| 5. Developmental edit | Editor reviews structure; you revise | 6–12 weeks |
| 6. Copyedit | Line-level fixes, consistency, fact flags | 3–6 weeks |
| 7. Design and formatting | Cover, interior layout, ebook files | 3–8 weeks |
| 8. Proofread | Final check of formatted pages | 1–3 weeks |
| 9. Launch preparation | Pre-orders, early reviews, interviews and promotion | 8–12 weeks, overlapping stages 6–8 |
Add it up and these estimates come to roughly 8 to 16 months from idea to launch for a part-time author. Some stages overlap: you can commission the cover while the copyedit is happening, and launch work should start well before the book is final.
How long does self-publishing take once the book is ready?
The final upload is the fast part. Amazon's KDP help pages list up to 72 hours for a new ebook's detail page to go live, and similar timing for print on Amazon.com.
The slow part is everything before it. Rushing editing or launch prep to hit an arbitrary date is an easy way to publish a book that isn't ready.
How long does traditional publishing take?
Longer, because you're working on the publisher's schedule. For nonfiction, you'll usually sell the book on a proposal before it's finished, then write it under contract.
Literary agent Steve Laube estimates 3 to 9 months from contract to manuscript delivery and 9 to 12 months from editor to publication, about two years from idea to print. That doesn't include the time spent writing the proposal and finding an agent.
How long does it take to write a book in real life? Three example schedules
Averages only go so far. Here are three hypothetical authors writing a 50,000-word nonfiction book, to show how schedule changes the answer.
The early-morning writer
A consultant writes for 45 minutes before work, five days a week, and averages about 600 words a session. The first draft takes around 17 weeks, roughly four months.
Add a month of planning, two months of self-revision and beta readers, and three to four months of editing and production. The book launches about a year after the first outline.
The weekend writer
A manager can't write on weekdays, so she blocks four hours every Saturday and averages 2,500 words a session. That's about 20 weeks for the draft, similar to the early-morning writer.
The risk is missed weekends. Travel, illness or family plans can cost a whole week of progress at once, so the real draft often runs closer to six or seven months.
The sabbatical writer
A founder takes six weeks off to write full-time and averages 2,000 words a day. The draft is done in about five weeks.
But revision and editing don't speed up much. Editors, beta readers and designers work on their own schedules, so the book still takes six to nine months from start to launch.
Tip: Track words per session in a simple spreadsheet for the first two weeks. Your real average, not your hoped-for one, is the number to plan with.
How long does revising and editing take?
Longer than most first-time authors expect. A first draft is raw material, and turning it into a book usually means at least two full passes: one for structure and one for clarity.
Plan for revision to take at least as long as half your drafting time, and often as long as the draft itself. Then add the editor's turnaround time for each round, plus your time to work through their notes.
What makes writing a book take longer?
These are the factors that most often stretch timelines:
- No outline. Writers without a plan often draft, restructure and redraft, which can double the time.
- Editing while drafting. Rewriting chapter one for months before writing chapter two.
- Heavy research. Interviews, travel and reading eat time that never shows up as word count.
- Irregular writing. Long gaps mean rereading to remember where you were.
- Perfectionism. Waiting until a chapter is "right" before moving on.
- Skipping deadlines. Without an external date, the book drifts.
How can you write a book faster without hurting it?
You can't skip editing, but you can cut wasted time.
- Outline first. A chapter-by-chapter plan removes most of the "what do I write today?" problem. Our book outline templates give you a ready structure.
- Set a daily minimum. A small target you always hit beats a big one you often miss.
- Write at the same time each day. Habit removes the daily decision.
- Draft fast, revise slowly. Leave notes like [ADD EXAMPLE] and keep moving.
- Batch your research. Gather what the outline needs, then write; don't research mid-sentence.
- Book your editor early. Good editors are often scheduled weeks or months ahead. A booked slot is a real deadline.
- Dictate if it suits you. Some authors talk through a chapter, transcribe it and edit the transcript. It's a rough draft, but it's fast.

When should you start planning your book launch?
Earlier than most authors think. Many of the things that drive early sales, such as endorsements, early reviews, guest articles and podcast interviews, need weeks or months of lead time.
A good rule is to start launch planning once your manuscript goes to the copyeditor. Our free book launch timeline calculator turns your publication date into a dated plan, so you can see what needs to happen and when.
Podcast interviews in particular need a long runway, because shows often record weeks before episodes air. If you want those booked around your launch, our book launch marketing service handles the outreach and scheduling.
So how long will your book take?
Do the math for your own book. Pick a realistic word count for your category, divide by a daily target you can sustain, and you have your drafting time.
Then roughly double it, or more, for revising, editing and production. That's your honest timeline. Set a start date this week, because the clock only starts once you do.
