Why this range? 

The average head circumference depends on the age of a man, his genetics, height, and his head shape. For example, a man who has a round-shaped head and is 6 feet tall will have a big head circumference, as compared to a person of the same age and same height. In this, the head shape and genetics determine the head circumference of the men. 

Plus, people who are significantly taller, tend to have more bone mass, which, in turn, can support more muscle tissue and will have a bigger head size. 

Based on the research, the average male head size is between 22.5 inches and 24.2 inches in circumference.

No, you can’t change your head circumference. Head circumference primarily depends on the size of the skull. The skull size grows until humans reach puberty, and after that, there is no way to increase the size of the head. 

However, if you gain weight, at a high proportion, your head circumference will increase too because of the additional mass present in the forehead and other head areas. Although, the change in circumference if the head will be very small is likely between 0.5 – 1 cm. 

Another way to increase head circumference is by growing your hair. The longer and thicker your hair is, the bigger your head looks.
