Q1, Q2, Q3 and Q4 Journals 2026: Scopus and Web of Science Quartile Guide
Journal Quartiles (Q1 to Q4) divide academic journals into four equal percentile groups based on their citation impact. Here is how quartiles work in Scopus (SJR) and Web of Science (JCR) in 2026.
What is a Journal Quartile (Q1, Q2, Q3, Q4)?
A Journal Quartile is a statistical rank assigned to academic journals within a specific subject category based on citation impact metrics such as SCImago Journal Rank (SJR) in Scopus or Journal Impact Factor (JIF) in Web of Science.
In any given academic discipline (e.g., Artificial Intelligence or Cardiology), journals are ordered from highest impact to lowest impact and divided into four equal groups of 25% each:
Why a Journal Can Be Q1 in Scopus but Q2 in Web of Science
Researchers often discover that a journal holds different quartile ranks across databases. Here is why:
1. Different Metrics Used: Scopus calculates quartiles via SJR (which weights citations based on the prestige of the citing journal). Web of Science calculates quartiles using JIF or JCI metrics.
2. Subject Category Groupings: A journal may be assigned to "Computer Science" in Scopus but classified under "Information Systems" in Web of Science, altering its relative percentile rank.
