| Type of edit | Main focus | When it happens | What changes |
|---|---|---|---|
| Developmental editing | Structure, content, pacing, audience | First, after a complete draft | Chapters, scenes, arguments and organization |
| Line editing | Style, flow, word choice, tone | After revisions from the developmental edit | Sentences and paragraphs |
| Copy editing | Grammar, usage, consistency, style guide | After line editing | Errors and inconsistencies |
| Proofreading | Final typos and formatting errors | Last, after layout | Small mistakes only |
Most copy editors follow a style guide such as the Chicago Manual of Style. Developmental editors focus on the work before that stage. Skipping a stage can cause problems, so a book that needs structural work will not be fixed by proofreading alone.
