Major vs Minor Revision: What Journal Decisions Mean

In journal peer review, a major revision means the editor sees real merit in your paper but has substantive concerns (new analyses, restructuring, or clearer methods), and the revised version will usually go back to reviewers. A minor revision means the paper is essentially accepted once you make small, well-defined fixes, often checked by the editor alone.

Decision letters are written in a careful, coded language. Editors choose their category and their phrasing deliberately, and each choice tells you two things: how likely your paper is to make it, and how much work stands between you and acceptance. This post decodes both.

The journal decision scale, decoded

Most journals work with some version of a five-point scale. The labels vary (some journals say "revise and resubmit" instead of "major revision," some add a "moderate revision" tier, and thresholds differ from journal to journal), but the underlying logic is consistent.

Two cautions when you read your own letter against this table. First, journals differ: one journal's "major" is another journal's "minor," and highly selective journals set the bar for "minor" much higher. Second, the category matters less than the letter's specifics, which is why the sections below focus on what editors actually write.

What tips a paper from a minor revision to a major one?

Editors are not grading how many comments you received. Ten small comments can still be a minor revision; one serious comment can make it major. Three things usually decide the category.

The nature of the fix. If every issue can be resolved by explaining, rewording, or citing, the editor can verify that on their own, so minor. If any issue requires you to generate new evidence (a control experiment, a robustness check, a new statistical analysis, more data), the editor cannot judge the result without reviewer eyes, so major.

Whether validity is in question. Concerns about methods, sample size, statistics, or the logic connecting evidence to claims almost always trigger a major revision, because they touch whether the findings can be trusted, not just how they are presented.

Reviewer disagreement. When one reviewer is positive and another raises serious doubts, editors often choose major revision so the skeptical reviewer can re-examine the revised paper. The category is partly a routing decision: major means "the reviewers need to see this again."

A useful self-test when your letter arrives: go through each comment and ask, "does answering this require new evidence, or just a better explanation?" If everything falls in the second group, you are in minor-revision territory regardless of the label.

Is a major revision good news?

Yes, with a caveat. A major revision is an invitation, not a consolation prize. Editors rarely spend scarce reviewer time on papers they expect to reject; if they thought your paper could not clear the bar, they would usually have rejected it and moved on. Being asked to revise means the editor believes there is a publishable paper inside your manuscript.

The odds, framed honestly:

• Minor revisions usually end in acceptance. Barring new problems introduced during revision, the editor has already decided the paper belongs in the journal.
• Major revisions commonly succeed when authors respond thoroughly. Papers that come back with every point addressed, either fixed or convincingly argued, tend to clear re-review. Papers that come back with cosmetic changes and defensive replies tend not to.
• Neither is a guarantee. A major revision can still be rejected after re-review, and even a minor revision can go wrong if the revision creates new issues.

The practical implication: your revision behavior, not the original decision, is now the biggest variable you control.

How to respond: two different games

The right strategy differs sharply between the two decisions. Treating a major revision like a minor one is one of the most common ways authors lose a winnable paper.

Minor revision: speed, completeness, zero new issues

A minor revision is yours to lose. Three rules:

1. Do everything asked, or decline with a short, polite justification. Do not silently skip items.
2. Introduce nothing new. Do not restructure sections, add analyses, or rewrite passages nobody complained about. Every unrequested change is a new surface for problems. The one exception is a genuine error you discover yourself: fix it and disclose it in your response letter.
3. Return it fast, with a point-by-point response. Even when only the editor will check it, list each comment and state exactly what you changed and where. It makes acceptance a five-minute task instead of a re-read.

Our guide on how to respond to reviewer comments covers the point-by-point format in detail.

Major revision: triage first, then write

A major revision is won or lost twice: once in the manuscript, and once in the response letter. Before editing anything, triage the comments into three piles:

• Must do: anything touching validity (methods, analyses, missing controls, overstated claims). These decide the outcome.
• Should do: clarity, structure, and framing requests. Cheap to grant; grant them generously.
• Push back: points where the reviewer is wrong or the request is out of scope. Disagree on a small number of points only, with evidence and respect. Our post on writing a rebuttal letter shows how to do this without antagonizing anyone.

Then plan the work before touching the draft, and give the response letter as much care as the manuscript; reviewers often read it first. The full playbook is in our guide to revise and resubmit decisions.

Before the revision goes back, a pre-submission check with Thesify Reviewer, an AI peer review tool that reads your manuscript the way reviewers will, helps you catch new weaknesses your revision may have introduced before the original reviewers do.

How long does a revision take?

Deadlines and realistic timelines vary by journal and field, so treat these as common ranges rather than rules:

• Minor revision deadlines are commonly two weeks to a month. The work itself often takes a few focused days.
• Major revision deadlines are commonly one to three months, and some journals allow six, particularly where new experiments are expected. Lab-based and clinical work usually needs the long end; analysis- or text-driven revisions can move faster.
• Field norms differ. Fast-turnaround biomedical journals often set firmer, shorter windows; mathematics, economics, and the humanities tend to run longer cycles at every stage.
• Extensions are normal. If you need more time, ask the editor early and give a date. A realistic request granted in advance looks far better than silence past a deadline.

Remember that the clock does not stop when you resubmit: a major revision typically goes through another review round, so the time to a final decision includes reviewer availability, not just your own work.

The silent signals in decision letters

Beyond the category, editors telegraph their intent in phrasing. A few patterns worth reading closely (the examples below are composite examples based on common decision-letter language, not quotes from real letters):

"We would be pleased to accept your manuscript subject to satisfactory revision."

Strong signal. The editor has, in effect, decided: the revision is a condition, not a competition.

"We invite you to revise, although we cannot guarantee acceptance and the revised manuscript will be sent for further review."

A genuine second gate. Expect the skeptical reviewer to see the paper again; your response letter carries real weight.

"In particular, please address Reviewer 2's concerns regarding the statistical analysis."

When an editor singles out one comment, that comment is the decision point. Everything else matters less than resolving it convincingly.

"We would be willing to consider a substantially revised version as a new submission."

However gently worded, this is reject-and-resubmit, not a revision invitation. The bar is a materially different paper; for what usually drives that outcome, see our post on why papers get rejected.

Read your letter twice: once for the category, once for these signals. The second reading usually tells you more.

FAQ

Is a major revision good news?

Yes. It means the editor sees a publishable paper in your manuscript and is willing to commit further reviewer time to it. It is an invitation with conditions: the outcome now depends mostly on how thoroughly you respond.

How long does a major revision take?

Journals commonly allow one to three months, sometimes up to six where new experiments are expected, though norms vary by field and journal. Add another review round after resubmission before a final decision. If you need more time, request an extension early.

Can a major revision still be rejected?

Yes. Rejection after major revision happens when key concerns remain unresolved, when the response letter dismisses rather than addresses criticism, or when re-review surfaces new problems. Thorough, evidence-based responses to every point are the best protection.

Do minor revisions go back to reviewers?

Often not: many editors check minor revisions themselves, since the requested changes are contained and easy to verify. Some journals send them back to one reviewer for confirmation. Either way, a clear point-by-point response letter speeds the final decision.
