Scopus Quartiles Q1 to Q4: Meaning & Free Check

Picking a journal for your research paper soon raises one question: what quartile is it in? Is Q1 required, or is Q2 good enough? And how can you verify it? Quartile ranking is among the most searched yet least understood ideas in academic publishing.

Researchers are often told that promotion, accreditation, a PhD or a grant needs a Q1 or Q2 journal, yet many are unclear on what a quartile is, how it is worked out, why one journal can show different quartiles, and how SJR quartiles differ from Impact Factor quartiles. This guide covers all of that, including a free step-by-step check, seven myths set straight, and a frank look at how quartiles feature in Indian academic evaluation.

What Does a Scopus Quartile Mean?

A Scopus quartile places a journal into one of four equal groups — Q1, Q2, Q3 or Q4 — based on how its SJR score compares with other journals in the same subject category. Technically, SCImago calculates the quartile from Scopus data, so you will also see it called the “SJR quartile” or “SCImago quartile”. Whenever you quote one, name the system behind it so readers know exactly which ranking you mean.

Picture all Scopus-indexed journals that SCImago ranks in one subject area, such as Environmental Chemistry, ordered from highest to lowest SJR. The first 25% form Q1, the next 25% Q2, the next 25% Q3, and the last 25% Q4. A quartile is nothing more than that.

What Q1, Q2, Q3 and Q4 Mean in Practice

Takeaway for researchers in India: Both Q1 and Q2 are strong options. If a rule merely asks for a Scopus-indexed journal, any quartile satisfies it; if your institution weighs quality, Q1 counts for more in promotions, international visibility and grant applications. A well-matched Q2 journal is a sound, realistic target for a first paper from a PhD project.

What Is SJR, and How Does It Set the Quartile?

SJR means SCImago Journal Rank, a metric from the SCImago research group built on Scopus citation data. Unlike a plain citation count, SJR is prestige-weighted: a citation coming from a highly ranked journal carries more weight than one from a rarely cited journal, much as a respected expert’s recommendation outweighs a stranger’s.

• Even with comparable raw citation totals, two journals can end up with quite different SJR scores, because it matters which journals are citing them.
• SJR does not depend on journal size: it is an average per document, so publishing more articles does not raise a large journal’s score.
• Weighting by the prestige of the citing journal narrows, though does not eliminate, differences in citation habits across fields, which is why quartiles are worked out within categories.
• SJR scores and quartiles are released yearly and can be viewed free of charge, without a subscription, at scimagojr.com.

Calculating a Quartile: A Worked Example

Suppose a subject category has 200 ranked journals in a particular year. SCImago orders them by SJR and splits the list into four equal parts:

A journal ranked 48th falls in Q1, while one ranked 52nd falls in Q2, even though their SJR values might be nearly the same. So when two journals sit close to a boundary, look at the rank and SJR value, not just the quartile label.

SJR, Impact Factor and CiteScore Compared

Three metrics are in common use for judging journals, and each yields its own ranking. This is what each one does, and which of them provides the Scopus quartile:

Bottom line: the Scopus quartile (Q1–Q4) comes from SJR, while the Impact Factor is an unrelated metric taken from another database. Q1 by SJR is possible with no Impact Factor whatsoever, and such a title is still a Q1 journal wherever Scopus-based criteria apply. To cover the Web of Science side, see our guide to WoS Q1–Q4 quartiles; for how impact factors are built and misused, see impact factor explained.

Checking Any Journal’s Quartile for Free

No Scopus subscription, library login or paid tool is needed. Two official free sources will do:

If you would like a starting list, JMVRA’s list of Scopus indexed journals can be browsed subject by subject; each title still has to be verified on SCImago and the Scopus Sources page. The Sources page is walked through in detail in our Scopus search guide.

Why One Journal Can Show Different Quartiles

Here is a frequent puzzle: you see Q1 for a journal, while a colleague sees Q2 for the same one. Both can be right, since the journal appears in more than one subject category and is ranked separately in each. When two figures disagree, ask which category and year each person looked at before assuming a mistake.

• A journal is often listed under two, three or even more categories, such as Environmental Engineering together with Environmental Chemistry.
• Each category ranks the journal separately, and since the competition differs, the quartile can differ too.
• A multidisciplinary journal might be Q1 in its main field but Q2 or Q3 in secondary fields where its citation impact is weaker.
• Websites may also display different years, or mix up the SJR quartile with the JIF quartile.

Practical advice: cite the quartile for the category that best fits your paper and always give the category and year with it — for example “Q2 (Environmental Chemistry, SJR 2025)”. Some committees accept the best quartile in any of the journal’s categories, while others insist on your own discipline. If your rule says nothing, ask, and keep the reply.

Why Quartiles Shift Each Year

Quartiles are recalculated annually from fresh citation data, so they move. A journal that was Q1 three years ago can be Q2 now if other journals in its category have grown faster or its own citations declined. Typical causes include:

For this reason, use the year that fits your purpose — normally the year of publication — and state which year you used.

7 Frequent Misunderstandings About Quartiles

Quartiles and Academic Requirements in India

Quartiles come up often in Indian appraisal, accreditation and funding. It helps to distinguish national rules from local practice:

• Nationwide rules seldom name quartiles. Under the UGC’s 2018 regulations, research papers earn scores according to journal type and impact factor, not Scopus quartile. Universities, institutions, funders and award committees tend to set their own quartile thresholds.
• Your university sets the PhD rules. Publishing in a journal is no longer a nationwide condition for submitting a thesis under the UGC’s 2022 PhD regulations, yet numerous universities keep publication requirements of their own in their ordinances, so check yours.
• Accreditation and rankings look at indexed output. Reports for NAAC and NIRF usually rely on papers indexed by Scopus and Web of Science; a quality indicator like quartile can support a case, though it is up to assessors to interpret it.

Recording Quartile Evidence

State the quartile that held in the year of publication, and say that this is the year you mean. Do not relabel an older paper if the journal later rises; and if it falls or is discontinued, your record still reflects what was true at publication, although evaluators may notice the change, so hold on to the evidence.

Finding Q1 and Q2 Journals in Your Field

1. Browse your category on SCImago — pick the subject area and category, choose the latest year and sort by SJR. Q1 and Q2 journals appear at the top.
2. Study each journal’s aims and scope — a strong quartile counts for nothing when the journal never publishes studies like yours.
3. Read recent issues — study article types, methods and length; they reveal more about fit than any metric does.
4. Narrow the list with a journal finder — matching your topic to suitable journals is what the JMVRA Journal Finder is for.
5. Examine every candidate closely: its listing on the Scopus Sources page, the publisher’s site, the ISSN and the review policy, with our predatory journal checklist as your guide.
6. Weigh up the practicalities — costs, open access choices, the review model and whether waivers exist.

Choosing a Journal: Looking Beyond the Quartile

A quartile reflects a journal’s citation standing, not whether it suits your paper. Before submitting, weigh these points together with the quartile:

Our journal selection guide takes you through the whole decision.

Quartiles Across Disciplines

Every quartile is worked out inside its own category, so two Q1 journals from different disciplines can carry widely different SJR values. Most of that gap comes down to citation habits:

That is also the reason an SJR figure from one field should not be set against one from another. Compare like with like — journals from the same category and the same year.

Planning Publications by Quartile

Researchers who publish often seldom target the same tier with every paper. A simple plan balances ambition with realism:

1. Match the paper to the tier. Your strongest and most novel results merit a Q1 attempt, while solid incremental work often suits Q2 or Q3 well.
2. Draw up a shortlist of three journals — one ambitious, one realistic and one safe fallback, all matching your scope.
3. Use reviewer feedback. A rejection from a Q1 journal that comes with detailed comments can greatly strengthen the paper for the next journal.
4. Avoid simultaneous submission. Send the paper to one journal at a time, and withdraw it formally before moving on.
5. Keep a log. A simple spreadsheet can hold the journal, quartile, category, year and supporting evidence for every paper.
6. Remember what is actually required. Where your institution only counts indexing, one Q2 paper placed well can serve you better than many months of repeated Q1 submissions.

Bogus Quartile Claims on Journal Websites

Quartiles matter for careers, so they are also misused. Be alert to these claims:

Cloned journals imitate the names and ISSNs of genuine ranked journals, so read our cloned journal alert before submitting to any unfamiliar venue.

How JMVRA Fits In

A quartile is not necessary for every paper. Many student projects, first papers, and applied or regional studies are better placed in a genuine, affordable, peer-reviewed open access journal — as long as your institution’s rule does not demand Scopus or a specific quartile.

Practical Tips for Using Quartile Rankings Wisely

Quartile labels summarise a journal's standing within a subject category, but they say little about your particular paper. Use them as one input among many, and document how you reached each decision.

• Confirm the subject category first. A journal can sit in several categories, and its standing may differ between them. Note which category matches your field before quoting any ranking to a supervisor or committee.
• Look at the year you need. Rankings are recalculated regularly, so a label seen in an old article or website may be outdated. Check the year relevant to your requirement and write it down.
• Capture evidence when you check. Save a screenshot or note of the source, category and date whenever you verify a journal. If someone later questions your claim, you can show exactly where it came from.
• Weigh fit above prestige. A highly ranked journal that does not publish your kind of work leads only to rejection. Read recent issues and judge whether your paper truly belongs in that company.
• Distrust third-party ranking claims. When a website or email boasts about a journal's position, verify it directly at the official source. Unchecked claims are a common feature of misleading publishers.

Treat quartile information as a verified, dated clue about a journal, and always combine it with a careful judgement of fit.

Questions Researchers Often Ask

In Summary

Whether a journal is Q1, Q2, Q3 or Q4 in Scopus terms tells you its standing among peers within a single subject category and a single year, as ranked by SJR. The measure is useful, costs nothing to check and is common in Indian and international evaluation, yet it is easy to misinterpret.

Bear these essentials in mind. A quartile is tied to a field, is derived from SJR and not from the Impact Factor, shifts every year, and cannot on its own show that a journal is genuine or suitable for your paper. So find the present quartile for your category on SCImago, confirm Scopus coverage, read what your institution requires, and store dated evidence.
