How Long Does It Take to Edit a Book? (Proofread, Copy Edit, Developmental)

Most authors ask this question too late. They finish the draft, pick a launch date, and then discover that a good edit can't be squeezed into the gap. The honest answer is that a proofread can take about a week, a copy edit two to four weeks, and a developmental edit anything from four weeks to several months once you count your own rewriting. Below you'll find the realistic range for each type of edit, a timeline table for 60,000, 80,000 and 100,000-word books, and a simple way to plan your launch date backwards.

Key takeaways#

• A proofread usually takes about a week, a copy edit two to four weeks, a line edit two to four weeks and a developmental edit four to eight weeks, for a typical book.
• Those are the editor's first pass only. Your own review and rewriting time often takes as long again, and it's the part authors forget.
• Length matters. A 100,000-word manuscript takes noticeably longer than a 60,000-word one, because editors work through a fixed number of words an hour.
• The edits run in order (developmental, line, copy, proofread), so the times add up. Plan four to six months for all four, before any waiting list.
• Work backwards from your launch date, and add a buffer. Rushed edits are how mistakes reach print.

The short answer: how long each type of edit takes#

Here are the typical first-pass times for a book of 60,000 to 80,000 words. "First pass" means the editor's own working time, from the day they start to the day they send the manuscript back.

• Proofread: about 5 to 7 working days. This is the quickest edit because the editor reads for typos, missed words and stray punctuation rather than rewriting anything.
• Copy edit: about 2 to 3 weeks. Grammar, spelling, hyphenation, capitalisation and consistency, sentence by sentence.
• Line edit: about 2 to 4 weeks. It's slow because the editor is working on rhythm, clarity and word choice in every paragraph.
• Developmental edit: about 4 to 8 weeks. The editor reads the whole book as a critical reader, then writes a detailed report on structure, pacing and argument.

These ranges match what we see at HMD, and they sit in the same area as the timings published by independent UK editors. Individual editors vary, so always treat an editor's own quote as the final word.

If you're not sure which of these your manuscript needs, our guide to proofreading vs copy editing shows what each pass catches, and do I need an editor? helps you decide whether to book one at all.

How long does it take to edit a 60,000, 80,000 or 100,000-word book?#

Word count is the biggest factor. Editors don't skim. Whether they're checking commas or questioning your plot, they're reading every word, so a longer book simply means more hours.

That connects to how editors charge. The Chartered Institute of Editing and Proofreading (CIEP) publishes suggested minimum hourly rates, and from 1 March 2026 they're £31.92 for proofreading, £37.11 for copyediting and £42.66 for developmental editing. They're guidance rather than a price list, but they show the basic idea: editing is paid by the hour, and a bigger or messier manuscript takes more hours. Our guide to how much book editing costs in the UK covers the money side.

The table below is our planning estimate. We've taken HMD's published turnaround ranges and stretched them for length. It shows the editor's first pass only.

A few notes on reading it:

• Proofreading on a laid-out book takes longer than on a Word file. If you can, proofread after formatting, so the proofreader sees the pages your readers will see.
• A clean manuscript is faster than a messy one. If your draft has never been through a spell-check, or you've left a trail of half-finished comments in the margins, the editor slows down.
• Fiction and non-fiction differ. Technical non-fiction with references, tables or lots of numbers takes longer to copy edit than a straightforward novel.

What happens after the first pass (the part that eats your calendar)#

Editing isn't one handover. It's a conversation, and your side of it takes time too.

1. 1Intake. You send the manuscript and a few details such as British or American spelling, and any style choices you care about.
2. 2First pass. The editor works through the manuscript with tracked changes and comments.
3. 3Your review. You go through every change, accept or reject it, and answer the editor's queries. For a copy edit or proofread that's a few days. After a developmental edit, you might rewrite whole chapters, which can take anything from a few weeks to a few months.
4. 4Second pass. The editor checks your responses and tidies up what's left. At HMD this second pass adds another 5 to 10 working days, depending on how much you changed.
5. 5Final delivery. You get the finished manuscript back, with a style sheet if you asked for one.

The biggest variable is you. If you take a month to answer the editor's queries, the second pass starts a month later. Block out the review time in your diary before you book the edit.

How long all the edits take, one after the other#

Authors who want the full treatment on a longer book often ask for the whole sequence. The order matters, because each edit assumes the one before it is finished. There's no point polishing sentences you're about to cut.

For an 80,000-word book, a realistic run looks like this:

• Developmental edit: 5 to 7 weeks
• Your rewrite: 4 to 8 weeks
• Copy edit: 3 to 4 weeks
• Your review of the copy edit: 1 to 2 weeks
• Formatting: 1 to 2 weeks
• Proofread: 1.5 to 2 weeks (about 7 to 9 working days)

Add that up and you get roughly 15 to 25 weeks, so four to six months. That's with an editor who can start the day you're ready. Many good independent editors are booked weeks or even months ahead, so add a waiting period on top.

Most independent authors don't do all four. A common route is a copy edit plus a proofread, or a line edit plus a proofread. Our guide to developmental editing vs copy editing and our explainer on what line editing is will help you pick the passes your book needs.

What slows an edit down#

Plan for these, and you'll rarely be caught out.

• Rewriting during the edit. If you change chapters while the editor is working, they have to read the new material fresh. That's a new edit, not a revision. If more than about 10% of the book changes between passes, expect a re-edit quote.
• A manuscript that isn't finished. Edit a locked draft. If you're still adding scenes or reworking the argument, hold off until the text settles.
• Mixed spelling and style. British and American spellings in the same file, or three ways of writing numbers, add a lot of query time. Decide before you start.
• Slow query answers. Silence on a query means the editor has to guess, and you might not like the guess.
• Waiting for a slot. Good editors are often booked ahead, so the start date can matter as much as the edit itself. Book early.

What to ask an editor about timing#

Before you pay, ask these five questions:

1. 1When can you start, and when will the first pass come back?
2. 2Is the turnaround based on my exact word count?
3. 3How long do I get to respond to your queries?
4. 4What happens to the schedule if I make big changes mid-edit?
5. 5Is a second pass included, and how long does it take?

A good editor answers these without fuss. Get the dates in writing.

How to plan your launch date backwards#

Pick your launch date, then subtract.

1. 1Start from the day you want the book live.
2. 2Take off a buffer of two to three weeks for ordering proof copies and fixing anything you find.
3. 3Take off time for cover design, formatting and uploading. Our book launch checklist lists the steps.
4. 4Take off the proofread, with a few days either side for your review.
5. 5Take off the copy edit and your review.
6. 6If you need one, take off the developmental edit and your rewrite.
7. 7Subtract any waiting time before your editor can start.

The date you land on is the date your draft needs to be finished. If it's already in the past, move the launch rather than squeezing the edit. You can see the whole journey in our guide to how to self-publish a book in the UK.

Can you speed up an edit?#

Sometimes, and only a bit. You can speed up your own side by doing a careful self-edit first, because a cleaner draft means fewer queries and a faster pass. Beta readers can catch the big structural problems before you pay a professional. Our guide on how to find beta readers shows you where to look. Our free Word Count tool tells you exactly where your manuscript stands, which is the first number any editor will ask for.

What you shouldn't do is push an editor to compress a developmental edit into a week. Rushed edits miss problems. If you really are short of time, ask about a rush option rather than asking an editor to hurry.

How long editing takes at HMD#

Our editing packages come with fixed turnarounds. These are the days quoted for the editor's work on a manuscript within each package's word limit, and each package includes tracked changes and an editorial summary report.

Word limits matter. Many novels are longer than the largest package, so for a longer manuscript we give a free exact quote, normally within 1 business day, with a turnaround to match your word count. If you'd like to see how an editor works on your own pages before you commit, send up to 1,000 words for a free sample edit. You get it back with track changes and feedback, normally within 24 to 48 hours, with no obligation. You can read exactly how a project runs on our editing process page, and our proofreading page covers the final-pass option.
