Line editing vs copyediting: what’s the difference?

Clear comparison of line editing and copyediting—what each changes, when to buy which pass, and how they fit with developmental work.

Editors use overlapping labels. Authors hear “line edit” and “copyedit” as synonyms. They are not—though a good professional pass often blends both.

Line editing

Focuses on style, rhythm, and flow at the sentence and paragraph level: awkward phrasing, repetition, tonal slips, show-vs-tell balance, dialogue tags, and paragraph propulsion.

Copyediting

Focuses on correctness and consistency: grammar, punctuation, spelling, hyphenation, continuity, and a project style sheet. Clarity yes—voice surgery only when necessary.

What should you buy?

  • Readers love the story but prose feels flat or clunky → line-leaning edit
  • Story works; you need professional cleanliness → copyedit
  • Structure still moving → developmental first

FAQ

Is line editing the same as developmental editing?

No. Developmental editing addresses structure, character arcs, pacing, and argument. Line editing improves how sentences and paragraphs perform once the big pieces mostly stand.

Can one editor do both line and copy?

Yes. Many combined passes exist. Ask what percentage of the work is stylistic vs mechanical, and request a sample.
