What Does an IQ of 118 Mean?
Key facts about IQ 118
- 118 is in the range that studies commonly report as the average for physicians, attorneys, and PhD holders — demanding professions cluster here rather than above 130.
- In a random group of 100 people, someone scoring 118 would typically out-score about 88 of them.
- Roughly 932 million people worldwide would score 118 or higher — and about 7.2 billion would score below it.
IQ 118 in depth
An IQ score of 118 is in the high-average band (110–119) — clearly above the population mean, though short of the top decile threshold. Roughly one person in four scores above 110, so this is elevated but not rare territory.
In everyday terms, this range typically shows up as picking up new abstract material a bit faster than most peers, being comfortable with layered instructions, and doing well in academically standard environments without heroic effort. It is the most common band among university graduates.
The practical ceiling at this level is essentially absent: research on professional achievement finds people in the high-average range fully represented in medicine, law, engineering, and research. Above roughly this band, additional IQ points correlate with outcomes far more weakly than motivation and opportunity do.
What this range tends to look like day to day
- New systems and abstract frameworks are absorbed comfortably quickly
- Standard academic paths feel demanding but not overwhelming
- Verbal, spatial, or numerical strengths may sit noticeably higher than this composite
- Performance gains now come mostly from depth of practice, not raw speed
A score of 118 sits in what studies of workplace performance often call the "sweet spot" band: high enough that cognitive screening is passed everywhere, common enough that plenty of colleagues share it. Nothing in the research suggests a meaningful career or academic door is closed at this level.
IQ 118 on other test scales
Different tests use different standard deviations, so the “same” performance produces different numbers. A 118 on an SD-15 test (Wechsler-style, and this site) corresponds to:
| Scale | Used by | Equivalent score |
|---|---|---|
| SD 15 | Wechsler (WAIS/WISC), most modern tests, this site | 118 |
| SD 16 | Older Stanford–Binet forms | 119 |
| SD 24 | Cattell (used by some high-IQ societies) | 129 |
| Percentile | All scales | 88th |
Where 118 sits among all classifications
| Range | Classification | Share of population |
|---|---|---|
| ≤ 69 | Extremely Low | 2.1% |
| 70–79 | Borderline | 6.5% |
| 80–89 | Low Average | 15.6% |
| 90–109 | Average | 49.5% |
| 110–119 | High Average ← IQ 118 | 16.6% |
| 120–129 | Superior | 7.2% |
| 130–144 | Very Superior (Gifted) | 2.3% |
| 145–159 | Highly Gifted | 0.1% |
| 160+ | Exceptionally Gifted | <0.1% |
How reliable is a score of 118?
Any single IQ score has a measurement error of roughly ±5 points, and scores from unsupervised online tests vary more than professionally administered ones. Treat this number as the middle of a range, not a fixed property of your brain.

Is an IQ of 118 good?
An IQ of 118 is above average — comfortably inside the range where about half the population scores. At this level, outcomes are driven by skills, habits and opportunity far more than by a few IQ points.
What percentile is an IQ of 118?
On a standard scale with mean 100 and SD 15, an IQ of 118 is at the 88th percentile (z-score 1.20). That means about 88% of people score below it.
How rare is an IQ of 118?
About 1 person in 9 scores 118 or higher. Worldwide, that is on the order of 932 million people.
Is an IQ of 118 gifted?
Not by the most common definition: the usual gifted cutoff is 130, and 118 is 12 points below it. Given the ±5-point measurement error of any single test, a score of 118 means a retest could plausibly land closer to the line.
Can I raise an IQ of 118?
Measured scores move with test familiarity, sleep, stress and effort — often by 5–10 points — so a first online attempt frequently understates ability. Underlying fluid intelligence, however, is stable in adulthood: "brain training" apps have repeatedly failed to raise it. What reliably grows is domain skill and knowledge, which is what actually drives most real-world performance.
