Every online IQ test is an estimate, and we say so openly. Each test length shows its margin of error before you start. Shorter tests are faster, longer tests are more precise, and the choice is always yours.

Other IQ sites charge $6.99 for a result certificate. Ours is 100% free, a personalized certificate with your name, IQ score, band, percentile and four-domain breakdown.
Every score is placed on the standard IQ scale (mean 100, SD 15), the same scale used by professionally administered tests like WAIS and Stanford-Binet.
Our scoring starts from a disclosed provisional model and keeps improving as real attempts accumulate. There are no black boxes here. You can read the full method, the accuracy margins and the limitations on our methodology page.

Online IQ tests give useful estimates. For a clinically validated result, see a licensed psychologist. Read our methodology →
An IQ test measures your reasoning ability through tasks like pattern recognition, number series, spatial puzzles and verbal analogies. Your performance is converted to an IQ score on a scale where 100 is average. Most people score between 85 and 115.
Our free IQ test covers four cognitive domains: spatial reasoning, numerical reasoning, logical reasoning and verbal reasoning. Each domain is tested equally, so your result reflects a balanced picture of your abilities rather than a single skill.
You can choose a quick 10 question IQ test for a fast estimate, the 20 question version for a solid result, or the full 40 question assessment for the most accurate score. Try our sample questions first if you want to see the format before you begin.
Everything people ask before taking the test.
No account. No email. No waiting. Just answer the questions and see where you stand.
