Guide to book editing

Types of Editing: Developmental, Line, Copy, Proofreading and Costs

What each kind of editing fixes, the order they come in, what they cost in 2026, and how to run the same passes on your own book.

By Chandler SuppleUpdated 12 min read

There are four main types of editing, and they come in this order: developmental editing fixes the story's structure, line editing improves how each sentence reads, copyediting makes the text correct and consistent, and proofreading catches the last typos on the final pages. Freelance editors charge about 1¢ to 5¢ a word, so each stage of an 80,000-word novel costs roughly $800 to $4,000.

You rarely need all four. Traditional publishers edit the books they buy at no cost to the author, and a self-published book can get by with two hires: one for the big picture and one for the final checks. Below you'll find what each type fixes, one paragraph taken through every stage, current rates, and an order for editing the book yourself first.

Based on the Editorial Freelancers Association's service definitions and Writer Beware's guide to editors.

Editing moves from the biggest problems to the smallest because each stage can undo the next. There's no point polishing sentences in a scene you're about to cut, or proofreading pages that will change.

The names aren't standard

Writer Beware notes that editing terms are fluid: some editors sell light, medium and heavy edits instead. In the UK, line editing can mean something close to proofreading, as Reedsy points out. Before you pay, ask for a written list of what the edit covers and a sample edit of a few pages.

Developmental editing: the big picture

A developmental edit looks at the book as a whole: whether the plot holds together, whether the middle drags, whether your main character drives the story, and whether the ending pays off. The Editorial Freelancers Association (EFA) says it also goes by substantive, structural or content editing. The editor's findings come back as a manuscript evaluation or an editorial letter.

Get one when the draft is finished and you've revised it as far as you can alone. Reedsy's guide to developmental editing names the usual signs: something feels off but you can't say what, beta readers lost interest partway, or agents' rejections mention structure. A developmental editor won't correct your grammar. They'll tell you which scenes to cut, move or build up.

A cheaper middle step is a manuscript assessment, also called an editorial assessment or critique. You get the letter without the detailed margin notes. Editors on Reedsy average 2.5¢ a word for an editorial assessment, against 3.6¢ for a full developmental edit.

The editorial letter is the heart of the edit. Chantel Hamilton, a developmental editor writing in Jane Friedman's guide to working with editors, describes a multi-page letter that explains the notes in your manuscript. You revise, send it back, and repeat two or three times with narrower notes each round. She also splits the stage in two: developmental editing as coaching while you write, and substantive editing as notes on a finished draft. The EFA and Reedsy treat the two names as one service.

ExampleFrom an editorial letterWritten for this guide, not from a real letter

The strongest thing in this draft is Mara herself. She wants the conservatory badly enough that I believed she'd lie to her mother for it. The weakest is the middle. From chapter 9 to chapter 15 she waits for a letter, and waiting isn't a goal. Give her something to do while she waits, perhaps the audition piece she still can't play, so the middle becomes a fight she can lose.

Two smaller notes. We first hear about the application in chapter 9, so the letter's arrival has no build-up; plant it in chapter 2. And the subplot with her cousin ends off the page in chapter 18. Either give it a scene or cut it.

  • What works comes first. Naming the strength tells the writer what to protect while revising.
  • Problem, reason, fix. Each note says what isn't working, why it matters to a reader, and one way to solve it, without rewriting a sentence.
  • Biggest first. The sagging middle leads; the smaller notes follow, so the writer knows where to spend the most time.

When a letter arrives, turn it into a plan before you open the manuscript. The revision plan tool sorts an editor's or beta readers' notes biggest first and ties each to its chapters. For a first opinion before you pay anyone, the AI book editor writes an editor's letter on a chapter, and the plot hole finder lists contradictions across the whole manuscript with both lines quoted.

Line editing, and how it differs from copyediting

A line edit works sentence by sentence on how the prose reads: clarity, rhythm, word choice, repetition, dialogue and tone. The EFA says line editors correct errors too, but their main focus is improving language and style. A good line edit keeps your voice. It should make you sound more like yourself, not like the editor.

A copyeditor asks a different question. The line editor asks whether a sentence reads well; the copyeditor asks whether it's correct and consistent. In practice the two blur. Reedsy doesn't sell line editing on its own, because its copy editors do both in one pass. Even The Chicago Manual of Style, as editor Sandra Wendel notes on Jane Friedman's blog, describes manuscript editing as "also called copy editing or line editing."

You can line edit a page yourself: read it aloud and fix whatever you stumble over. The AI line editor tightens one page at a time in your voice and marks every cut. The story rewriter changes a passage the way you choose, such as switching tense or point of view, or showing a key moment instead of telling it.

Copyediting and proofreading: the final checks

A copyedit corrects spelling, grammar, usage and punctuation, and builds a style sheet: a record of how your book spells names, writes numbers and uses hyphens, so every chapter matches. Copyeditors also catch continuity slips. Wendel's own example is a Peterson in chapter 1 who turns into a Petersen in chapter 6.

Proofreading comes last, ideally on the formatted pages of the book. A proofreader looks for typos that survived every earlier pass and for errors the layout added: bad word breaks, a lone line stranded at the top of a page, wrong page numbers, missing headers. Wendel is firm that proofreading isn't the time to revise, because changes on laid-out pages are slow and expensive.

If you're querying agents, the publisher that buys your book will copyedit and proofread it. What you send should still be clean and in standard manuscript format.

Why your own proofread misses things

Your brain fills in the words you meant to write. Read the final text in a different form from the one you drafted in, such as a printout or an e-reader, and read it aloud. Better still, hand it to someone who hasn't read the book.

One paragraph through every stage

Here is one draft paragraph as each kind of editor would treat it. We wrote it for this guide, with the kinds of problems real first drafts have.

ExampleThe draft, and the developmental noteWritten for this guide

Mara walked slowly into the kitchen and she saw that the letter was sitting on the table where her mother had left it, she felt her heart start to beat really fast. She had been waiting for this letter for three months, ever since she applied to the conservatory in Viena. She picked it up. She put it down again. Outside the rain was falling and the sound of it was very loud. She thought about her father, who had played violin in Vienna before the war, and how he would of wanted her to go.

  • Developmental note. As a moment, this works. But if this is the first time the reader hears about the application, the letter carries no weight. The fix belongs in chapter 2, not in this paragraph.
ExampleAfter a line editWritten for this guide

Mara stopped in the kitchen doorway. The letter lay on the table where her mother had left it, and her heart began to race. Three months she had waited for it, ever since she applied to the conservatory in Viena. She picked it up. Put it down. Outside, rain hammered the street. Her father had played violin in Vienna before the war. He would have wanted her to go.

  • Filter words cut. "She saw that" and "she felt" put a layer between the reader and Mara, so they go.
  • Stronger verbs. "Walked slowly" becomes "stopped", and "very loud" rain becomes rain that hammers.
  • Rhythm. The long first sentence is split, and "Put it down" is clipped to echo her hesitation. "Would of" is fixed in passing.
ExampleAfter the copyedit and proofreadWritten for this guide

Mara stopped in the kitchen doorway. The letter lay on the table where her mother had left it, and her heart began to race. Seven months she had waited for it, ever since she applied to the conservatory in Vienna. She picked it up. Put it down. Outside, rain hammered the street. Her father had played violin in Vienna before the war. He would have wanted her to go.

  • Spelling. "Viena" is corrected to Vienna and added to the style sheet.
  • Continuity. Chapter 2 has Mara apply in March, and this scene is set in October, so three months becomes seven.
  • Proofread. On the typeset page, the proofreader marks a doubled "the the" and a last word stranded alone at the top of a page.

How much does editing a book cost?

Most freelance editors charge by the word, and the deeper the edit, the higher the rate. The EFA's 2026 rate chart gives the middle range of rates its members charged in 2025, from a survey of more than 1,100 editors. Reedsy's editing cost guide gives the range its editors quote. Here are both for fiction, with what they mean for an 80,000-word novel.

Rates also depend on the kind of book. In the EFA's chart, memoir and nonfiction cost more per word to edit than fiction.

To estimate your own cost, multiply your word count by the rate. Our guide to novel word counts has typical lengths by genre. Some editors charge by the hour instead: the EFA lists $52.50 to $70 an hour for fiction developmental editing and $40 to $50 for copyediting. Reedsy adds that quotes rise with a rush deadline, a messier manuscript or a more experienced editor.

Pay for one or two stages, not four

Hamilton recommends at least two professionals before you self-publish: one for the big-picture edit, and a second for the copyedit and proofread. If your budget covers only one, spend it where your draft is weakest and run the other passes yourself.

Beta readers, critique partners and editors

A beta reader is a reader, not an editor. They tell you where they were gripped, confused or bored; an editor tells you why, and how to fix it. Traditionally, beta readers are unpaid: friends, writing group members or fellow writers who swap manuscripts. Writer Beware warns that paid beta reading sold by editing services is really a professional critique, so know which one you're buying.

Use readers before an editor, not instead of one. Fix what several readers agree on, then pay a professional to look at what's left. For a quick first read of a chapter, the AI beta reader reports where a reader would be hooked, get lost, or stop.

Which kind of editing do you need?

Where to start, by the state of your draft

If your draftStart with
Feels wrong but you can't say why, or readers lose interest partwayA developmental edit, or a cheaper manuscript assessment
Holds together, but the sentences feel flat or wordyA line edit
Reads well, is final, and you're self-publishingA copyedit, then a proofread of the formatted pages
Is about to go to literary agentsYour own revision and beta readers; a paid edit is optional

If you're querying agents, you don't have to hire an editor first. Writer Beware says publishers don't expect professionally edited manuscripts, because any book a reputable publisher buys is edited in-house at no cost to the author. It adds that writing "professionally edited" in a query won't improve your chances.

Self-publishing is different, because nobody else edits the book. Writer Beware's advice for self-publishers who want a lasting readership is to hire an editor, because in a crowded market a professional product is essential.

Edit your own book first, in this order

Whether or not you hire anyone, run the same ladder yourself, biggest problems first. Every problem you fix is one you don't pay an editor to find.

  1. Let the draft rest

    Put it away for a few weeks, so you come back to it more like a reader than its author.

  2. Read it through once

    Read the whole book in as few sittings as you can without fixing anything. Jot one line per chapter on what happens and where your attention slipped.

  3. Fix the structure

    Work on stakes, plot holes, pacing and the ending before you touch a sentence. Big changes now save you from polishing scenes you later cut.

  4. Revise scene by scene

    Check that each scene changes something, and cut or merge the ones that don't. Run the self-editing checklist on every chapter.

  5. Line edit aloud

    Cut filler, repeated words and the habits you know you have. Anything you stumble over aloud, a reader will stumble over silently.

  6. Copyedit with a style sheet

    List names, places, spellings and how you write numbers as you go, then search the manuscript for each one.

  7. Proofread in a new format

    Print it, or read it on an e-reader or with text-to-speech, slowly enough to see every word.

Before you send it to an editor

  • The draft is finished, and you've revised it at least once yourself
  • You know which kind of edit you're buying
  • You've seen a sample edit of a few of your own pages
  • You have a written contract with the price, the deadline and what's included
  • You know whether a second round or follow-up questions are included

How to hire an editor and avoid a bad one

Anyone can call themselves an editor, so check before you pay. Writer Beware and Hamilton's guide agree on the basics.

  • Choose someone who edits your genre. Look for editors thanked in the acknowledgments of books like yours, and read books an editor has worked on.
  • Ask for a sample edit or sample critique of a few pages. Many editors offer one, and it shows you their style before you commit.
  • Get a written contract that covers the work, the price, when it's due, who does the editing, and whether a second round is included.

Warning signs

Be wary of an editor who promises a bestseller or a book deal, contacts you out of the blue, won't give a firm price, or was recommended by an agent or publisher who profits from the referral. Writer Beware lists each of these as a caution sign.

Questions authors ask

Common questions

What is developmental editing?

Developmental editing is the first and broadest stage of editing. The editor reads your whole manuscript and reports on its structure, plot, pacing, characters and point of view, usually in an editorial letter with notes in the margins. It doesn't fix grammar or sentences. It's also called structural, substantive or content editing.

What's the difference between line editing and copy editing?

Line editing improves how your sentences read: rhythm, clarity, word choice and voice. Copy editing makes them correct and consistent: grammar, spelling, punctuation, and names and facts that match across chapters, recorded in a style sheet. Line editing comes first. Many editors combine the two in one pass, so ask what a quote includes.

How much does it cost to edit a book?

At the median rates in the EFA's 2026 chart, an 80,000-word novel costs about $2,400 to $2,800 for a developmental edit, $1,600 to $2,160 for a copyedit and $960 to $1,600 for a proofread. Reedsy's 2026 quote data puts one round of editing at $1,920 to $4,560. Memoir and nonfiction cost more per word.

Do I need to hire an editor before querying agents?

No. Publishers edit the books they buy at their own cost, and Writer Beware notes that they don't expect a professionally edited manuscript. Revise it yourself, use beta readers, and query when it's as good as you can make it. A paid edit can still help if you're stuck, but it isn't required.

What does an editorial letter include?

An editorial letter is a developmental editor's report on your book, often several pages long. It names what's working, then the biggest problems, such as a sagging middle, unclear stakes or a flat ending, with suggestions for each. It usually comes with margin notes in the manuscript, and you revise from it, sometimes over two or three rounds.

Can I edit my own book?

Yes, and you should before anyone else reads it. Work from big to small: structure, then scenes, then sentences, then typos. Self-editing can't fully replace a fresh pair of eyes, because you read what you meant rather than what's on the page. Get at least one reader or editor to check the final text.
