You may wonder, "What should my IQ be? Am I normal?" When you see a number on a test, you probably ask right away: is this good, bad, or average? The honest short answer is: good compared to what? But don’t worry. In this article, I’ll show you exactly what the numbers mean with a clear table, and I’ll explain in simple terms what lies behind the question of what IQ “should” be.
First, let’s look at the IQ scale
Modern IQ tests are designed so that the average in society always comes out as 100. In other words, a score of 100 means right in the middle, the most typical point. Most scores cluster around that 100 mark, while very high or very low scores are rare. You can think of it like a bell curve: the peak is in the center, and it narrows toward the edges.
This distribution also has a measure of "spread." In IQ tests, that is usually 15 points. In practical terms, this means about two-thirds of people (68%) score between 85 and 115. About 95% score between 70 and 130. So far more people than you might think fall inside the broad band called "average."
IQ levels and meanings (table)
The table below shows the IQ ranges, based on the most commonly used classification, and roughly how common each one is in society:
| IQ Range | Level | Approximate Share of Society |
|---|---|---|
| 130 and above | Genius-level intelligence | ~2% |
| 120 – 129 | Very high (bright) | ~7% |
| 110 – 119 | High (above average) | ~16% |
| 90 – 109 | Average (normal) | ~50% |
| 80 – 89 | Below average | ~16% |
| 70 – 79 | Borderline | ~7% |
| Below 70 | Very low | ~2% |
One small note: these cutoff values are not exactly the same in every test. Some tests set the "gifted" threshold at 130, others at 131 or 132. So it is normal to see small differences from one source to another. What matters is which band your score falls into.
So what counts as a "good" IQ?
This is the key point. Looking at the table, you can see that 90 to 109 is considered average, and about half of people are exactly in that range. So if your score is around 100, that is not "mediocre" — it means you are in the most common and fully healthy part of society. A score of 95 and a score of 105 are both normal; there is no meaningful difference between them.
Anything above 110 is considered above average. Once you pass 120, you are in a small part of the population. A score of 130 and above is generally accepted as the threshold for genius-level intelligence, and that is roughly the top 2% of society — it is also the range sought by high-IQ groups like Mensa.
In short: the real answer to "What should IQ be?" is "it depends on your goal." For most people, a score around 100 is perfectly good and completely normal.
Your score is not set in stone
One thing to keep in mind: an IQ score is not a permanent label from a single test. The same person can get slightly different results on different days or in different tests. Poor sleep, stress, distraction, and even your motivation at the time can affect the outcome. Every serious test has a margin of measurement error, which means your score really represents a small range of possible points.
Online tests can still give you a useful idea, but remember: a test on the internet cannot replace one given by a specialist in a clinical setting. It is a fun and useful indicator, not an official diagnostic tool.
What does IQ measure, and what does it not?
IQ tests measure specific mental abilities such as logical reasoning, pattern recognition, short-term memory, and processing speed. These matter, but they are not the whole of life. IQ does not measure:
- Creativity and imagination
- Emotional intelligence, empathy, and relationships
- Determination, discipline, and hard work
- Character, curiosity, and success in life
So a high IQ alone does not guarantee success, and a low score does not mean your fate is sealed. Mental skills, like muscles, can grow stronger over time with the right exercises.
