Where 110 sits on the bell curve
This score is 10 points above the average of 100, or 0.67 standard deviations. The shaded part of the curve, everyone who scores lower, covers about 74.8% of people.
What an IQ of 110 means
110 is where the High Average range begins. It sits two thirds of a standard deviation above the mean, so about three in four people score lower.
The High Average range runs from 110 to 119. Range names come from the Wechsler scales; they are labels for parts of the curve, not hard lines, so 109 and 111 reflect almost the same performance.
Whether 110 counts as a good score depends on the comparison: against everyone, or against the people you study or work with.
How rare is an IQ of 110?
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: about 7.6
- In an office of 250: about 63
- In a town of 10,000: about 2,525
- In a city of 1 million: about 252,493

110 and the usual reference points
- 10 points above 100, the average by definition.
- 5 points below 115, one standard deviation above average (about the 84th percentile).
- 20 points below 130, two standard deviations above average and the usual Mensa line (top 2%).
- 35 points below 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 110 is best read as "probably between 105 and 115". 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.

How accurate is an online IQ score of 110?
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.
