How to Choose the Right Book Editor: Types of Editing Explained

What Every Nonfiction Author Needs to Know Before Hiring an Editor

Introduction

Every book needs editing. That is not a reflection of your writing ability. It is a reality of the publishing process. Even the most experienced authors rely on professional editors to refine their work, catch blind spots, and ensure the final product meets readers' expectations.

But "editing" is not a single service. There are several distinct types of editing, each serving a different purpose at a different stage of the process. Hiring the wrong type of editor, or hiring an editor at the wrong stage, wastes money and delays your project.

This guide explains the major types of book editing, when you need each one, and how to find the right editor for your nonfiction book.

The Four Main Types Of Book Editing

Professional publishing uses four levels of editing. Think of them as stages in a process, moving from big-picture structure down to individual characters on the page.

Developmental Editing

Developmental editing (sometimes called content editing or structural editing) is the highest level of editing. A developmental editor looks at the big picture: the overall structure of your book, the organization of chapters, the strength of your arguments, the clarity of your central thesis, and whether the book delivers on its promise to the reader.

A developmental editor might suggest reorganizing chapters, combining or splitting sections, strengthening weak arguments, removing redundant material, or adding new content to fill gaps. They focus on what you are saying and whether it works, not on how individual sentences are written.

This is the type of editing that has the most dramatic impact on the quality of your book. It is also the stage most authors skip, which is a mistake.

When you need it: When your manuscript is complete (or nearly complete) but you are not sure if the structure, flow, and content are as strong as they could be. Developmental editing is especially valuable for first-time authors.

Line Editing

Line editing focuses on the quality of the writing at the sentence and paragraph level. A line editor refines your prose for clarity, flow, tone, and readability. They tighten wordy passages, smooth awkward transitions, eliminate jargon, and ensure your voice is consistent throughout the book.

Line editing is not about fixing grammar or catching typos. It is about making good writing better. A line editor helps you say what you mean more clearly, more concisely, and more engagingly.

When you need it: After developmental editing (or if your structure is already solid) and before copyediting. Line editing is ideal when the content is right but the writing itself needs polishing.

Copyediting

Copyediting is the detailed, technical pass that most people think of when they hear "editing." A copyeditor checks for grammar, spelling, punctuation, syntax, and consistency. They ensure your style is uniform (are you using "e-mail" in one chapter and "email" in another?), your facts are accurate, and your formatting is consistent.

Copyeditors typically follow a style guide (such as the Chicago Manual of Style, which is standard for book publishing). They catch errors that spell-check misses and ensure the manuscript is clean and consistent from front to back.

When you need it: After line editing and before proofreading. Copyediting should happen on a manuscript that is content-complete and will not undergo further structural changes.

Proofreading

Proofreading is the final quality check before publication. A proofreader reviews the formatted, laid-out version of your book (not the manuscript) and catches any remaining typos, formatting errors, or inconsistencies that slipped through earlier rounds.

Proofreading is not a substitute for copyediting. It is a safety net. A proofreader works with the finished layout, checking things like page numbers, headers, spacing, orphan and widow lines, and any errors introduced during the design process.

When you need it: After the interior layout is complete and before you approve final files for printing and distribution.

DO YOU NEED ALL FOUR TYPES?

Not necessarily. The level of editing you need depends on your manuscript and your experience as a writer.

If you are a first-time author, a full editorial process (developmental, line, copy, proof) gives you the best chance of publishing a polished, professional book.

If you are an experienced writer with a well-organized manuscript, you might skip developmental editing and start with line editing or copyediting.

At a minimum, every book should receive copyediting and proofreading. Publishing a book with grammatical errors, inconsistencies, or typos damages your credibility and leads to negative reviews.

HOW MUCH DOES BOOK EDITING COST?

Editing costs vary widely based on the type of editing, the length of your manuscript, and the editor's experience. Here are typical ranges for a 50,000-word nonfiction manuscript:

• Developmental editing: $2,000 to $5,000
• Line editing: $1,500 to $4,000
• Copyediting: $1,000 to $3,000
• Proofreading: $500 to $1,500

Some editors offer combined services (for example, line editing and copyediting in a single pass). Package pricing from a publishing company often bundles editing with other services like design and formatting.

How To Find And Vet A Book Editor

Finding a qualified editor requires some research. Here is what to look for:

Relevant Experience

Look for an editor who has experience with nonfiction in your subject area. An editor who specializes in business books understands different conventions than one who works primarily with memoir or academic texts.

A Sample Edit

Most professional editors offer a sample edit of a few pages so you can evaluate their work before committing. This is standard practice and a red flag if an editor refuses.

References and Portfolio

Ask for references from previous clients. Look at books they have edited. Check whether those books are professionally produced and well-reviewed.

Clear Communication

Your editor should be able to explain what they will do, how long it will take, and what you will receive. Vague promises or unclear timelines are warning signs.

Professional Credentials

Many editors are members of professional organizations like the Editorial Freelancers Association (EFA) or ACES: The Society for Editing. Membership is not a guarantee of quality, but it indicates professional commitment.

Common Editing Mistakes Authors Make

Skipping Developmental Editing

Many authors jump straight to copyediting because they want their grammar cleaned up. But if the structure is weak, no amount of polished prose will save the book. Developmental editing is the foundation.

Hiring Based on Price Alone

The cheapest editor is rarely the best value. Editing is skilled, time-intensive work. An editor charging $300 to edit an entire book is either cutting corners or lacks experience.

Editing Too Early

Do not hire an editor until your manuscript is as complete as you can make it on your own. If you are still rewriting chapters, you will waste money editing content that gets deleted or rewritten.

Not Understanding What You Are Buying

Make sure you know which type of editing you are getting. "Editing" without further specification could mean anything from a light proofread to a full developmental overhaul. Ask explicitly.

How Jetlaunch Handles Editing

At Jetlaunch Publishing, editing is a core part of our publishing process. Every manuscript goes through a thorough editorial workflow tailored to the author's needs and the manuscript's current state.

We start by assessing the manuscript to determine which levels of editing are needed. Our editors specialize in nonfiction and understand the unique demands of business books, memoirs, self-help titles, and thought leadership works.

Throughout the process, we use tracked changes so authors can see every edit and approve or reject individual suggestions. Our goal is to strengthen your book while preserving your voice. A good editor does not rewrite your book. They make your book sound more like the best version of you.

Final Thoughts

Editing is not optional. It is the difference between a book that builds your credibility and one that undermines it. Understanding the different types of editing helps you invest wisely, hire the right professionals, and publish a book you are genuinely proud of.

The best time to think about editing is before you finish writing. Knowing that a developmental editor will review your structure can free you to write more boldly, knowing that a professional will help you refine it later. And knowing that a copyeditor will catch your mistakes lets you focus on getting your ideas down without obsessing over every comma.

Write with confidence. Edit with professionals. Publish with pride.
