Is an IQ of 87 good?
"Good" isn't the most useful frame here. An IQ of 87 is somewhat below the midpoint of the scale, but IQ captures only abstract reasoning — not memory for what matters to you, practical skill, creativity, or drive. Everyday reasoning and most jobs and courses remain well within reach, and a single online test is an estimate, not a fixed measure of a person.
How rare is an IQ of 87?
An IQ of 87 is fairly common: about 19% of people score lower and 81% score higher, so it sits within the normal spread of scores rather than at any extreme.
What an IQ of 87 looks like in practice
Differences within and just below the average band rarely show up clearly in daily life. Interest, effort, and familiarity with the kind of puzzles a test uses can move a single result more than people expect.
IQ 87 compared to nearby scores
No short test pins ability to a single point. An IQ of 87 is best read as the centre of a range — roughly 83 to 91 — 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.
