On the standard scale that is 6.33 standard deviations above average. No test has been checked against enough people to confirm a score this high.
An IQ of 195 falls in the profoundly gifted IQ range, which starts at 160. Find 195 on the IQ chart, or check how rare any score is with the IQ rarity calculator.
IQ 195: beyond what most tests can measure
A 195 is 35 points past the ceiling most major tests publish. The model rarity, about 1 in 8.3 billion, describes about 1 people worldwide, which is far beyond anything a test has been checked against.
Major individually administered adult tests typically report full-scale scores up to about 160. A reported number above that usually comes from extended norms, a different scale or extrapolation.
Real populations may not follow the bell curve perfectly in the far tails, so rarity figures this extreme are illustrations, not head counts.
How claims like "195 IQ" arise
A 195 almost never comes from a modern, supervised adult test. It usually comes from somewhere like this:
- Ratio IQ. Early childhood tests divided mental age by real age. A 6-year-old solving puzzles like a typical 11.7-year-old got a ratio IQ of 195. Modern deviation IQs do not work this way.
- Different scales. Some tests use a standard deviation of 24, so a 195 there is about 159 on the usual SD 15 scale.
- Unnormed online quizzes. A test with no norm data can print any number. Very high outputs usually say more about the scoring than the person.
Famous estimates: Newton, da Vinci and the 160+ club
Nobody in history has a measured IQ of 195. The highest estimates on this site, for figures such as Isaac Newton and Leonardo da Vinci, come from reading their work and lives, not from tests. 42 profiles here are estimated at 160 or more.
As far as anyone knows, Albert Einstein never took an IQ test. The 160 figure repeated online is an estimate. See the Einstein profile for what it rests on.
How many people have an IQ of 195 or higher?
Scoring 195 or higher is a 0.000000012% share of everyone. Scaled up to whole populations, that works out as:
| Where | Population | IQ 195+ |
|---|---|---|
| UK | 68 million | fewer than one (effectively zero expected) |
| US | 335 million | fewer than one (0.04 expected) |
| World | 8.1 billion | 1 |
You would need the whole world to expect about one person at 195 or higher.
Exactly 195, counting anyone between 194.5 and 195.5, is about 1 in 19 billion. In the US that is fewer than one person, and in the UK fewer than one person.
Treat these as orders of magnitude, not census data. They apply the standard model to everyone, and individual tests have their own norms.
How rare is an IQ of 195?
An IQ of 195 or higher is 8.2 times rarer than 190 or higher, and 200 or higher is 9.2 times rarer again. At this point on the curve, each extra point makes a score about 54% rarer.
What your 195 could really be. Even a good supervised test has a margin of error of roughly 5 points either side, and far more at this height. A true score from 190 to 200 would span rarities from 1 in 1 billion to 1 in 76 billion.
Which scale was it on? A 195 reported on an SD 16 scale converts to about 189 on the usual SD 15 scale, and one from an SD 24 scale (seen in some Cattell-style results) to about 159. Check which scale your score report used.
Famous people with an estimated IQ near 195
Nobody famous has a verified IQ in most cases, and retrospective estimates are only made for a narrow group.
No historical figure on this site has an estimate close to 195. Retrospective estimates cluster between about 115 and 250 because they are only made for people with exceptional achievements. That is a selection effect, not a sign that famous or successful people cannot score 195.

Percentiles and counts use a normal distribution with mean 100 and standard deviation 15. Real tests have their own norms, confidence intervals and ceilings, so treat every figure here as an approximation, not a diagnosis. Two tests often give different numbers for the same person: here is why.
