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.

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.
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.
