Where 160 sits on the bell curve
This score is 60 points above the average of 100, or 4.00 standard deviations. The shaded part of the curve, everyone who scores lower, covers about 100.0% of people.
What an IQ of 160 means
160 is four standard deviations above the mean, about 1 in 31,600 people. It is the highest full-scale score the WAIS-IV reports, so on that test 160 is a ceiling rather than an exact measure.
The Very Superior range runs from 130 to 160 and beyond. Range names come from the Wechsler scales; they are labels for parts of the curve, not hard lines, so 159 and 161 reflect almost the same performance.
Whether 160 counts as a high IQ depends on the comparison: against everyone, or against the people you study or work with.
How rare is an IQ of 160?
If scores follow the standard bell curve, this is how many people you would expect to reach this score or higher:
- In a class of 30: fewer than one
- In an office of 250: fewer than one
- In a town of 10,000: fewer than one
- In a city of 1 million: about 32
160 compared with nearby scores
| IQ | Percentile | Range | How rare |
|---|---|---|---|
| 150 | 99.96th | Very Superior | 1 in 2,300 |
| 155 | 99.99th | Very Superior | 1 in 8,100 |
| 160 | 99.997th | Very Superior | 1 in 31,600 |
"How rare" counts people at that score or higher.
160 and the usual reference points
- 60 points above 100, the average by definition.
- 45 points above 115, one standard deviation above average (about the 84th percentile).
- 30 points above 130, two standard deviations above average and the usual Mensa line (top 2%).
- 15 points above 145, three standard deviations above average (about 1 in 741).
How much to trust a single score
No test measures IQ exactly. Clinical tests such as the Wechsler scales report a confidence interval of roughly 5 points either side, so a measured 160 is best read as "probably between 155 and 165". Quick online tests carry wider ranges, which is why our free test shows a 90% range next to every result.
Scores also move between sittings. Tiredness, stress and practice with the puzzle types can each shift a result by a few points, so the range name tells you more than the exact number.
Frequently asked questions
Is 160 a good IQ score?
Yes. An IQ of 160 is in the Very Superior range (130 to 160) and higher than about 100.0% of people. About 1 in 31,600 people score 160 or higher.
What percentile is an IQ of 160?
An IQ of 160 is at about the 99.997th percentile. On the standard scale (mean 100, standard deviation 15) it is +4.00 standard deviations from the average.
How rare is an IQ of 160?
About 1 in 31,600 people score 160 or higher, which is 0.00% of the population.
Is an IQ of 160 real?
It is possible on the scale, but extremely rare: about 1 in 31,600. On the WAIS-IV, 160 is the highest score the test can give, so a result of 160 means 'at or above the ceiling'. Online tests cannot measure it reliably.
How accurate is an online IQ score of 160?
Treat it as a range, not an exact number. Clinical tests report a confidence interval of roughly 5 points either side, and short online tests have wider ranges, so read any single result as a band rather than an exact point.
