Getting started

What the test is, who it's for, and what makes it different.

What is an IQ test?

An IQ test estimates your reasoning ability against a standard scale where 100 is the average. The single number matters less than what each domain (verbal, spatial, logical, working memory) says about how you think. Our full test asks 60 questions across those four domains, takes about 30 minutes, and uses adaptive scoring, so harder questions you get right count for more.

Beyond the test, the site has 40 brain-training games, community puzzle questions, and a research library on intelligence science.

How is your test different from other free IQ sites?

Three things.

Real scale: Scores are calibrated to the standard 100-mean, 15-SD scale, not an internal “fun” score.
Four subscores: Verbal, spatial, logical and working memory, not just one headline number.
Nothing in the way: No signup, no email gate, no paywall after the test.

The methodology page explains the scoring math in plain English.

Who can take the test?

Anyone 13 or older. Norms are calibrated for adults but work for teenagers and seniors too, and your percentile is computed against your age group.

Teens, 13–17: Same questions; your percentile reflects your age group.
Adults, 18–64: The default, and where norms are tightest, since the research sample is largest here.
Seniors, 65+: Same test. Processing-speed scores trend slightly lower with age, which the percentile accounts for.

What languages is the test available in?

Nine: English, Spanish, German, Russian, Chinese, Arabic, Hindi, Indonesian and Turkish. Questions and answers are translated; scoring is identical in every language.

Pick your language before you start. Switching mid-test won't carry your progress over.

How the test works

Length, format, what to expect, how to prepare.

Which test should I take?

Three lengths, all using the same scoring math, plus related tools.

Full IQ test: 60 questions, about 30 minutes. The most accurate score and the cleanest domain breakdown.
Quick IQ test: 20 questions, up to 20 minutes. Useful when you're short on time; subscores are a little noisier.
Practice test: 10 sample questions with instant feedback, so you know the format before committing.
Specialized tests: Standalone reasoning, memory and other sub-tests if the full test is broader than you need.
Brain training: 40 short games for the abilities the test measures. Free, no signup.

How should I prepare?

You can't really study for an IQ test, but you can avoid the things that lower your score.

Quiet space: Phone away, notifications off, nobody interrupting for 30 minutes.
Rest first: Take it when you're alert. Tiredness noticeably lowers processing-speed scores.
One sitting: Don't refresh or switch tabs mid-test: answers save in the browser, but timers reset.

You can retake the test. Wait at least a few days between attempts so practice effects don't inflate your score.

What do I need to take the test?

Almost nothing: the test runs entirely in your browser.

Browser: Chrome, Firefox, Safari or Edge, anything updated in the last two years.
Internet: Just enough to load the questions. Once loaded the test runs locally, so brief drops are fine.
Screen: Spatial questions are easier on a bigger screen. Phones work, but rotation tasks are harder on them.
Time: About 30 minutes for the full test, less for the quick one.

Your results

How the score is calculated, what the percentile means, how to read your subscores.

What do my results include?

Everything appears the moment you finish, with no paywall and no email gate.

Overall IQ: One number on the standard 100-mean scale, computed from your responses across all four domains.
Percentile: Where your score sits relative to the population.
Four subscores: Verbal, spatial, logical and working memory, each scored separately so you can see your shape.
Permanent link: Your result lives at its own unique URL, stored permanently. Bookmark it, share it, or close the tab.

What does my IQ score mean?

On the 100-mean scale most people fall between 85 and 115. The usual bands:

Below 70: Significantly below average. If results like this are consistent or causing concern, a formal evaluation gives more context.
70–84: Below average.
85–115: Average: about two-thirds of the population.
116–130: Above average: roughly the top 16 percent.
131–145: Gifted range: roughly the top 2 percent.
146–160: Highly gifted: roughly the top 0.1 percent.
Above 160: Extremely rare, and beyond the reliable range of any 30-minute test, including this one.

IQ measures one slice of intelligence: academic and reasoning ability. It doesn't capture creativity, social intelligence, drive or wisdom.

Which cognitive domains do you measure?

Four, the same four most modern IQ instruments measure.

Verbal: Vocabulary, analogies and reasoning through language. Closely tied to reading and academic performance.
Spatial: Mental rotation, visual patterns, fitting shapes together. Useful for engineering, design and STEM.
Logical: Pattern recognition, inference and abstract problem-solving: the closest single measure to fluid intelligence.
Working memory: Holding and manipulating information in your head.

Privacy & data

What we collect, what we don't, and how anonymous your result really is.

How do you handle my data?

Minimally.

Anonymous by default: No signup, no email, no name. Your result is tied to a random ID, not to you as a person.
No sharing: We don't sell or share data with anyone. Aggregate percentile data is anonymized.
GDPR: European users have full rights under GDPR. Cookie consent is genuine: opt out and we honor it.
Encrypted: All traffic uses HTTPS, and server access is restricted and audited.

Want your data removed? Email editorial@whats-your-iq.com and we'll delete it within a few days.

What control do I have over my data?

Full control.

View it: Your result link shows everything we hold about your test: score, percentile and subscores.
Delete it: Email us to remove your stored result. Clearing your browser data removes the local copy.
Export it: Save the result page as a PDF or screenshot; the permanent link works too.
Skip cookies: Decline analytics in the cookie banner. The test works exactly the same.

Saving & support

Saving your result, contacting us, coming back later.

How do I save my result?

There's no account system, by design. Your result is stored permanently at its own link, so the link is your record.

Bookmark it: Return to the same result page any time.
Save as PDF: Use your browser's print-to-PDF for an offline copy.
Share it: Send the link to a friend and compare your domain breakdowns.

No password to lose and no account to recover.

My question isn't here. How do I reach you?

By email. A real person reads it, usually replying within a day or two.

General: editorial@whats-your-iq.com
Privacy: Same address, with “privacy” in the subject line.
Bugs: Include the page URL and your browser. The more specific, the faster we can fix it.

Technical issues

Browser support, mobile, and what to try if something goes wrong.

Something broke during the test. What now?

Try these in order.

Refresh: Answers save locally as you go, so a refresh usually picks up where you left off.
Clear the cache: If a question shows the wrong content, clearing the site cache and reloading fixes most cases.
Switch browser: Older mobile browsers can struggle with the spatial questions.
Email us: If nothing works, write to editorial@whats-your-iq.com with what happened.

Which devices and browsers work?

Pretty much anything updated in the last two years.

Browsers: Chrome, Firefox, Safari and Edge: current and previous major version.
Mobile: iOS Safari and Android Chrome both work.
Desktop: Windows, macOS and Linux. Recommended for the full test.
Screen: 1024×768 or larger is comfortable; phone screens work but cramp the spatial questions.

If your setup should work and doesn't, send us your browser version and we'll investigate.
