Types of Book Editing: Which One Does Your Book Need?

There are four main types of book editing: developmental editing, line editing, copy editing and proofreading. They happen in that order, each one works at a smaller scale than the last, and most books don't need all four. The right choice depends on how finished your manuscript is, not how much you want to spend.

This guide explains what each type of book editing does, what it typically costs in 2026, how long it takes, and how to work out which one your book needs before you hire anyone.

The four types of book editing at a glance

Costs are for fiction, based on Reedsy's 2026 marketplace data and the Editorial Freelancers Association's 2026 rate survey. Nonfiction usually costs more per word.

1. Developmental editing (structural editing)

Developmental editing looks at the whole book rather than individual sentences. The editor asks whether the story or argument works: does the plot hold together, is the pacing right, do the characters change, does each chapter earn its place?

What you get: Usually an editorial letter of several pages explaining the big issues and how to fix them, plus notes in the manuscript margins. You do the rewriting; the editor diagnoses.

You need it if:

• This is your first or second draft.
• Beta readers lose interest in the same place.
• You know something isn't working but can't say what.
• Your nonfiction book feels repetitive or out of order.

Example: A developmental editor might tell you your story's main tension resolves in chapter nine but the book runs to chapter twenty-five, so the second half has nothing driving it.

If you're not sure your book needs a full developmental edit, a manuscript assessment is a cheaper first step. The editor reads the whole book and writes a shorter report on the main issues, without the chapter-by-chapter notes.

2. Line editing

Line editing works paragraph by paragraph. The editor improves how your sentences read: cutting repetition, tightening loose phrasing, smoothing rhythm and making sure the tone stays consistent. A good line editor keeps your voice and makes it clearer.

You need it if:

• The structure is settled but the prose feels flat, wordy or uneven.
• Readers say the book is "slow" even though the plot is sound.
• You're writing in a second language and want the writing to sound natural.

Line editing vs copy editing: Line editing asks "does this sentence work as well as it could?" Copy editing asks "is this sentence correct?" Many editors combine the two in one pass for books that need a lighter touch.

3. Copy editing

Copy editing makes the text correct and consistent. The editor fixes grammar, spelling and punctuation, and checks that names, dates, timelines and terms stay the same throughout the book. In the US, most copy editors follow The Chicago Manual of Style.

What you get: Your manuscript in tracked changes, plus a style sheet listing your book's spellings, capitalization and character names, so later editors and designers stay consistent.

You need it if: Your manuscript is structurally finished and you won't make big changes afterward. Almost every book benefits from a copy edit, even when the author is a strong writer, because it's very hard to spot errors in your own work.

4. Proofreading

Proofreading is the final check, done on the formatted pages just before publishing. The proofreader catches remaining typos plus layout problems introduced during formatting: bad line breaks, wrong page numbers, missing headers, inconsistent spacing and hyphenation errors.

Editing vs proofreading: Proofreading isn't a cheaper replacement for editing. A proofreader won't fix unclear sentences or weak structure; they assume the text is already right and check the finished pages for mistakes.

You need it: Always, for any book going to print. Formatting errors often cause print rejections. (See our guide to fixing KDP upload errors.)

Which type of editing does your book need?

Work through these questions in order and stop at the first "no":

1. Is the structure working? Have beta readers or a trusted reader finished it without losing interest? If no → developmental edit or manuscript assessment.
2. Does the writing read smoothly? Are you happy with how the sentences sound aloud? If no → line edit.
3. Is the text finished? Will you avoid major rewrites from here on? If yes → copy edit.
4. Is the book formatted? Once the pages are laid out → proofread.

For most self-published authors with a revised manuscript, the usual combination is a copy edit plus a proofread. First-time authors working from an early draft usually get the most value from a developmental edit or manuscript assessment first, because there's no point polishing sentences in chapters that might be cut.

How much does book editing cost?

Editors usually charge per word, sometimes per hour or per page (one page is about 250 words). The EFA's 2026 survey of more than 1,100 editors found these fiction ranges:

Price goes up with:

• Word count. An 80,000-word novel costs about twice as much as a 40,000-word one.
• Genre. Nonfiction, technical and academic books need fact and citation checks.
• The manuscript's condition. A rough draft takes far longer per page than a clean one.
• Deadline. Rush jobs usually cost more.

How long does book editing take?

Editing is slow, careful work. The EFA's survey puts copy editing fiction at about 6–10 pages an hour, so an 80,000-word manuscript (about 320 pages) needs roughly 32–53 hours of editing time for a single pass. Proofreading runs faster, at about 10–15 pages an hour.

In calendar time, typical turnarounds (which vary by editor and manuscript) are:

• Manuscript assessment: 1–3 weeks
• Developmental edit: 3–6 weeks, plus your rewrite
• Copy edit: 2–4 weeks
• Proofread: 1–2 weeks

Build in time to review the edits yourself. Accepting or rejecting tracked changes on a full novel takes most authors a week or more.

How to choose a book editor

Whoever you hire, check these before you pay:

• A sample edit. Ask for a short sample of your own pages. It shows the editor's style and whether they understand your book.
• A written quote and scope. You should know exactly which type of editing you're paying for and what you'll receive.
• Genre experience. A thriller, a memoir and a business book need different editing.
• Tracked changes. You should approve every change; nothing should be rewritten without your say.
• Clear timelines for each stage and for questions afterward.
• Your rights stay yours. Paying for editing should never give anyone rights to your book.

Be cautious of anyone offering every type of editing for a very low flat price, or promising that editing will make your book a bestseller.

Frequently asked questions

What is the difference between editing and proofreading?

Editing improves the content and writing: structure, clarity, flow and correctness. Proofreading is a final check of the formatted pages for typos and layout errors. Proofreading comes last and doesn't replace editing.

What type of book editing do I need?

If your draft is early or you're unsure whether the story works, start with a developmental edit or manuscript assessment. If the structure is settled, you likely need a copy edit, possibly with a line edit. Every book should be proofread after formatting.

How much does book editing cost?

For fiction, copy editing typically costs 2.0¢–2.7¢ per word and proofreading 1.2¢–2.0¢ per word. A developmental edit of an 80,000-word book averages about $2,880. Nonfiction usually costs more.

How long does book editing take?

A copy edit of a typical novel takes about 2–4 weeks; a developmental edit 3–6 weeks plus your rewrite; a proofread 1–2 weeks.

Do I need a developmental editor and a copy editor?

Not always. If your structure is already strong, a copy edit and proofread may be enough. A manuscript assessment can tell you before you commit to a full developmental edit.

Can an editor change my writing style?

A good editor shouldn't. Line and copy editors work to make your voice clearer, not to replace it, and every change should come to you in tracked changes for approval.

Do you edit fiction and nonfiction?

Yes. We edit fiction, memoir, nonfiction, business and children's books.

Can you also help me publish the book?

Yes. After editing, we can handle formatting, cover design and publishing setup in your own KDP and IngramSpark accounts.
