How Rare Is Your IQ?
Every IQ score corresponds to an exact slice of the population. Enter yours and see the 1-in-X rarity, your percentile, and a real-world comparison that makes the number tangible. Rarity is computed from the standard normal model used by all major IQ tests: mean 100, standard deviation 15.

In crowd terms: about one per school classroom or two.

Why Rarity Explodes in the Tails
The normal distribution is dense in the middle and vanishingly thin at the edges. Half the population scores between 90 and 110, so a ten-point move near the average barely changes rarity. Past 130, every additional ten points cuts the qualifying population by an order of magnitude or more. That asymmetry explains two things you see across this site: why genius-range scores dominate public fascination, and why our celebrity IQ estimates above 160 carry explicit disclaimers. Population statistics simply do not support a world full of verified 180s. For the deeper statistics, see our IQ percentile chart and the guide to IQ score ranges.
Frequently Asked Questions
How rare is an IQ of 130?
An IQ of 130 is two standard deviations above the mean, around the 98th percentile. Roughly 1 in 44 people score at or above this level, which is the common cutoff for gifted programs and high-IQ societies like Mensa.
How rare is an IQ of 145 or higher?
About 1 in 741 people score 145 or above. At 160 the rarity reaches roughly 1 in 31,000, which is why claimed scores at or above that level for public figures are almost always speculative estimates rather than verified results.
Is a rare IQ score always a high one?
Rarity is symmetric. An IQ of 70 is exactly as statistically rare as an IQ of 130, because the normal curve has two tails. This tool reports the rarity of the tail your score falls in.
