Free IQ Test: Measure Your Intelligence Quotient in 15 Minutes
Want to evaluate your intelligence quotient for free? You are at the right place. Our online IQ test allows you to measure your cognitive abilities in only 15 minutes, without registration and with instant results.
The intelligence quotient, or IQ, is a standardized measure of an individual's cognitive abilities. Contrary to popular belief, it does not measure "intelligence" as a whole but specifically evaluates your skills in logical reasoning, problem-solving, abstract thinking, and learning ability.
💡 Did you know that the average IQ of the population is 100, with a standard deviation of 15 points? About 68% of the population has an IQ between 85 and 115.

What is an IQ test?
An IQ (Intelligence Quotient) test is a set of standardized tasks designed to assess a person's cognitive abilities. Developed in the early 20th century by psychologists like Alfred Binet and William Stern, these tests have evolved to become recognized scientific tools.
Our free IQ test assesses 5 essential cognitive domains:
Logical Reasoning
Ability to identify patterns and solve abstract problems
Mental Calculation
Ability to manipulate numbers and understand numerical sequences
Spatial Vision
Ability to visualize and manipulate objects in space
Verbal Intelligence
Understanding of language, analogies, and vocabulary
How does our free IQ test work?
Our test has been designed to be both scientifically rigorous and accessible to all. Here's how it works:
- 20 progressive questions: questions are calibrated in order of increasing difficulty
- 15-minute time limit: this timer simulates official test conditions
- 5 categories assessed: logical, numerical, spatial, verbal, and pattern recognition
- Instant calculation: your IQ score is calculated according to a standardized scale (average 100, standard deviation 15)
- Detailed analysis: discover your strengths and areas for improvement by category
Understanding your IQ score
Once the test is complete, you will receive a score generally between 70 and 145. Here's how to interpret your result:
(2% of the population)
(10% of the population)
(50% of the population)
(16% of the population)
The IQ bell curve
IQ scores follow a normal distribution (bell curve). This means that the majority of people fall around the average (100), and extreme scores (very high or very low) are statistically rarer.
Why take an IQ test?
Knowing your IQ can be useful in several contexts:
- Better self-understanding: identify your cognitive strengths and areas for development
- Career guidance: certain professions particularly value certain types of intelligence
- High potential detection: a high score may indicate a high intellectual potential (HPI) profile
- Cognitive monitoring: compare your performances over time to measure the effect of brain training
- Simple curiosity: satisfy your desire to better understand your intellectual abilities
Tips to optimize your score
To get a result that faithfully reflects your abilities, follow these recommendations:
🎯 Before the test: Choose a time when you are rested and focused. Avoid distractions and settle in a quiet place.
- Get enough sleep the night before the test (7-8 hours recommended)
- Avoid alcohol and stimulants that can alter your performance
- Don't rush, but keep an eye on the timer
- Answer all the questions, even if you're not sure
- Trust your intuition for difficult questions
Frequently asked questions about the IQ test
Yes, our test is 100% free. You don't need to register or provide your bank details. You receive your complete results immediately after completing the test.
Our test is inspired by recognized IQ test methodologies (WAIS, Raven matrices). Although it does not replace a full psychometric assessment done by a professional, it provides a reliable estimate of your cognitive abilities.
IQ is relatively stable in adulthood, but you can optimize your performance by regularly training your brain. Our applications COCO, JOE, and EDITH offer daily cognitive exercises to stimulate your memory, logic, and concentration.
Our online test is designed for adults and teenagers from 16 years old. For children, specific tests like the WISC are better suited and must be administered by a psychologist.
You can retake the test as many times as you want. However, to get a reliable result, we recommend waiting at least 6 months between two sessions, giving you time to forget the questions.
