The standard for IQ is 85 to 115 points.

The numerical value of intelligence quotient is called IQ. The standard numerical test is a 200-point scale. It is generally considered that 85-115 points are within the normal range. A score of <70 is considered low intelligence, a score of 120-140 is considered smart, and a score of >140 is considered a genius. This range can fluctuate slightly, because test scores may be affected by special factors such as environment or stress, resulting in unbalanced scores. Therefore, a score ranging from 85 to 115 can be considered a normal value.

Generally speaking, the IQ test score of normal people is between 90 and 110 points. IQ is related to many factors, such as heredity, age and education level. However, the IQs of ordinary people are not much different, so there is generally no need to worry too much.
