How long does peer review actually take?
Across 3,620 journals reporting it, the median time to publication is 14 weeks. The fastest tenth manage 7; the slowest tenth take 29 or more.

Time to publication is the variable researchers care most about and can find out least about. Journals rarely advertise it, and when they do the number is usually chosen to flatter.
DOAJ requires listed journals to report average time to publication, which gives us a figure for 3,620 of the journals we track.
The distribution
| Weeks | |
|---|---|
| Fastest 10% | 7 or fewer |
| Median | 14 |
| Slowest 10% | 29 or more |
Half of biomedical journals publish within about three and a half months of acceptance. The spread either side is wide: some manage under two months, and a substantial tail takes seven months or longer.
What this number does not include
This is the part that catches people out. The DOAJ figure covers acceptance to publication — not submission to publication.
Your actual wait has three parts:
- Submission to first decision. Usually the longest and most variable stage, and the one nobody publishes data on. Weeks to many months, depending on how quickly the editor finds reviewers who say yes.
- Revision cycles. Entirely dependent on you and the reviewers. One round is normal; two is common.
- Acceptance to publication. The 14-week median above.
So a journal reporting 14 weeks may still mean nine months from the day you submit. Plan accordingly, especially against a thesis deadline or a promotion committee date.
Reading speed claims honestly
Fast is not automatically bad. Some journals genuinely run efficient operations: large editorial boards, a deep reviewer pool, a fully digital pipeline, no print schedule to wait for. A well-run megajournal can legitimately turn things around quickly.
But speed has to come from somewhere, and there are only so many places. Genuine peer review requires finding qualified reviewers, giving them time to read carefully, and letting authors respond. That does not compress below a few weeks.
“Acceptance within 72 hours” is not efficiency. No process that includes finding two experts, having them read your methods, and giving you a chance to respond completes in three days. A journal advertising that is describing the absence of review, and telling you so on its homepage.
Treat anything under two weeks from submission to acceptance as a claim that needs explaining, not a feature.
Using this when you choose
If you have a hard deadline, filter for it — but filter on the whole picture. A journal that publishes in eight weeks but rejects 90% of submissions will cost you more time than one that takes sixteen and is in scope. A desk rejection after six weeks puts you back at the start.
The fastest route to publication is usually submitting to the right journal first, not the quickest one.
