IQ Score Chart

What each IQ range is usually called, and roughly how many people fall into it. It applies to the estimate you get from this test, and to any IQ score reported on the standard scale.

IQ ranges on the standard scale (mean 100, standard deviation 15)
IQ range Band Share of people In plain words
130 and above Very superior about 2% Exceptionally strong reasoning across the areas tested.
120–129 Superior about 7% Clearly stronger reasoning than most people.
110–119 High average about 16% A little above the typical range.
90–109 Average about 50% Squarely in the typical range. About half of all people score here.
80–89 Low average about 16% A little below the typical range.
70–79 Borderline about 7% Below the typical range on this test.
69 and below Well below average about 2% Well below the typical range on this test. Tiredness, distraction or unfamiliar question styles can lower a score a lot.

How to read your score

On the standard scale, 100 is the middle. Scores are spread in a bell curve around it, so most people sit close to 100 and far fewer sit at the extremes. Each step of 15 points is one standard deviation: about 68% of people fall between 85 and 115, and about 95% between 70 and 130.

The band names come from the labels traditionally used with the Wechsler scales. They are descriptions of where a score sits, not verdicts. The shares are rounded and describe an idealised bell curve, so real populations differ a little.

A score is a range, not a point

Even professional tests report a margin of error of several points, and an unsupervised online test is looser still. If this test gives you 112, the honest reading is “somewhere around the high-average range”, not “exactly 112”. Do not read a big difference into a gap of a few points, and do not compare your number with a score from a different test as if they were the same measurement.
