Everything you need to know about taking an IQ test online.
An IQ (Intelligence Quotient) test is a standardized assessment designed to measure human cognitive abilities and intellectual potential. IQ tests evaluate pattern recognition, logical reasoning, spatial ability, verbal comprehension, and working memory. The average IQ score is 100, with most people scoring between 85 and 115. Our tests use visual pattern matrices, logical sequences, and analytical questions similar to those found in clinically administered assessments.
Yes, all six IQ tests on IQ Spectrum are completely free with no hidden fees, no paywalls, and no sign-up required. You can take as many tests as you like and receive instant results with a detailed cognitive breakdown. We also offer a free personalized IQ certificate sent directly to your email.
Our IQ tests are psychometrically calibrated using established cognitive assessment principles. They include visual pattern matrices, shape sequences, and spatial reasoning questions similar to those found in Raven's Progressive Matrices and other standardized tests. While no online test can replace a full clinical assessment administered by a licensed psychologist, our tests provide a reliable estimate of cognitive ability and are designed for both accuracy and entertainment.
Each of our six IQ tests contains 20 carefully designed questions and takes between 15 to 25 minutes to complete. You are timed during the assessment. Results are calculated based on accuracy and are displayed instantly when you finish, including your IQ score, percentile ranking, and a detailed cognitive category breakdown.
IQ Spectrum offers six distinct intelligence assessments: General IQ (classic cognitive test with visual pattern matrices and spatial reasoning), Financial IQ (budgeting, investing, and economic reasoning), Emotional IQ (empathy, self-awareness, and social intelligence), Logical/Analytical IQ (deductive reasoning and abstract puzzles), Fashion IQ (aesthetic intelligence and style knowledge), and Grammar & Vocabulary IQ (language mastery and verbal precision). We are also developing Personality Type, Love Style IQ, and Career Path IQ assessments.
The average IQ score is 100, and the standard deviation is 15 points.

About 68% of the global population scores between 85 and 115.
Yes! After completing any IQ test, you can request a personalized IQ certificate.

Your IQ score is calculated using a quadratic scaling formula based on the percentage of questions answered correctly. The scoring curve rewards higher accuracy levels disproportionately, similar to standardized IQ tests. Scores range from 70 to 155+, and you receive a percentile ranking that compares your performance to the general population distribution.
