Scores use the standard scale (mean 100, standard deviation 15) — the same scale IQGrab uses. Your percentile tells you what share of people score at or below you.
| IQ score | Percentile (approx.) | Classification |
|---|---|---|
| 145+ | 99.9th | Very superior |
| 140 | 99.6th | Very superior |
| 135 | 99th | Very superior |
| 130 | 98th | Very superior |
| 125 | 95th | Superior |
| 120 | 91st | Superior |
| 115 | 84th | High average |
| 110 | 75th | High average |
| 105 | 63rd | Average |
| 100 | 50th | Average |
| 95 | 37th | Average |
| 90 | 25th | Average |
| 85 | 16th | Low average |
| 80 | 9th | Low average |
| 70 | 2nd | Borderline |
| 55 | 0.1st | Extremely low |
About 68% of people score between 85 and 115; about 95% score between 70 and 130. The middle of the chart is crowded — a few points near 100 barely move your percentile — while the ends are rare: scores above 130 or below 70 each cover only about 2% of people.
A single score is an estimate, not a verdict. IQGrab reports every score with a ±6 margin — a score of 100 means the true range is roughly 94–106. Small differences between two scores usually mean nothing.
