What does an IQ of 105 mean?
An IQ of 105 sits in the Average band (90–109), the broad middle where about half of all people score. You scored higher than roughly 63% of people, which makes 105 a typical, unremarkable result on this scale — and that page explains why "average" is less limiting than it sounds.

Key takeaways
- An IQ of 105 is classified as Average (90–109).
- It is about the 63rd percentile — higher than 63% of people.
- Roughly half of all people score within the 90–109 band.
Is an IQ of 105 good?
Yes, in the way that matters most. "Average" here means your measured reasoning is in line with most people, and the everyday cognitive demands of work, study, and problem-solving are well within reach. It's also worth remembering that IQ captures a narrow slice of the mind — abstract reasoning — not creativity, motivation, social skill, or hard-won expertise, all of which shape real outcomes at least as much as a score of 105.
How rare is an IQ of 105?
An IQ of 105 is common, not rare — that's what makes it average. About 63% of people score lower and about 37% score higher, so in any ordinary room of people, plenty would land near 105.
What an IQ of 105 looks like in practice
Within the average band, small differences in score rarely translate into visible differences in daily life. People across this range handle the same jobs, courses, and decisions; factors like effort, interest, and experience usually matter more than a few IQ points.
What makes an IQ of 105 distinctive
An IQ of 105 sits just above the midpoint of the Average band — close enough to 100 that the five-point gap rarely shows in daily life, but on the higher side of typical. It is also one of the most common results there is: because the bell curve is tallest near the middle, far more people score around 105 than around any 'impressive' round number further out.
An IQ of 105 in your Cognitive DNA
Because 105 is a composite, it can be reached many ways. Our Cognitive DNA breakdown splits a score into eight abilities — pattern recognition, fluid reasoning, working memory, processing speed and more — so two people who both score 105 can have very different shapes: one even across the board, another strong in verbal reasoning but only average in spatial. The single number hides that profile; the breakdown reveals it.
IQ 105 compared to nearby scores
No short test pins ability to a single point. An IQ of 105 is best read as the centre of a range — roughly 101 to 109 — rather than an exact value, and it is not meaningfully different from scores a few points either side. When you compare two people, overlapping ranges matter more than the point scores.
Where 105 sits on the IQ scale
| IQ Range | Classification | % of People | What it means |
|---|---|---|---|
| ≤69 | Extremely Low | ~2.2% | Well below average. On clinical tests this range may warrant professional assessment. |
| 70–79 | Borderline | ~6.7% | Below average reasoning on this scale. |
| 80–89 | Low Average | ~16.1% | Slightly below the population average. |
| 90–109 | Average | ~50% | The middle of the distribution — where most people score. |
| 110–119 | High Average | ~16.1% | Above average reasoning ability. |
| 120–129 | Superior | ~6.7% | Notably above average — roughly the top 10%. |
| 130–144 | Gifted | ~2.1% | The conventional 'gifted' threshold (130) and above — top ~2%. Mensa qualifies here. |
| 145+ | Highly Gifted | ~0.1% | Exceptionally rare — the far right tail of the distribution. |
Frequently asked questions
Is an IQ of 105 good?+
An IQ of 105 is a solidly normal result. It means you reason about as well as most people and is no barrier to education, work, or everyday problem-solving.
What percentile is an IQ of 105?+
An IQ of 105 is about the 63rd percentile on the standard mean-100, SD-15 scale — meaning you score higher than roughly 63% of people.
How rare is an IQ of 105?+
A score of 105 is about 1 in 3, based on the normal distribution of IQ in the population.
Is an IQ of 105 average?+
Yes. The average band runs from 90 to 109 and contains about half of all people, so 105 sits squarely in the typical range — close to the population midpoint of 100.
Is an IQ of 105 above average?+
Yes, slightly. 105 is five points above the midpoint of 100 and sits in the upper half of the Average band (90–109), so you scored a little higher than most people — though the gap from 100 is small enough that it rarely shows in everyday tasks.
What is the difference between an IQ of 100 and 105?+
Statistically small. Both are firmly Average; 105 is about a third of a standard deviation above the mean. In practice the two are interchangeable for daily reasoning — interest, effort and experience matter far more than the five-point gap.
