The average height of a human head is 18–20 cm. This measurement is relatively constant, representing about 13% of a person's total body height, but can vary based on factors such as ethnicity, sex, and age.
Understanding Head Height
While the head's general shape is ellipsoid or ovoid, its height is usually quite consistent in a given individual. Here's a breakdown of factors affecting head height:
Average Head Height
- The average height of a human head typically falls between 18 to 20 centimeters.
- This dimension is used in various applications, including anthropometry and artistic proportions.
Relationship to Total Body Height
- Head height is usually about 13% of a person's total body height.
- For example, someone 170 cm tall might have a head height close to 22 cm.
Factors That Cause Variation
While the average range is consistent, certain factors can cause a slight variation in an individual's head height:
- Ethnicity: Different ethnic backgrounds may exhibit slight variations in average head size.
- Sex: Males tend to have slightly larger heads on average compared to females.
- Age: Head size changes most significantly during growth and development, and will change throughout life.
Practical Insights
-
Understanding average head height is useful in fields like:
- Ergonomics: Designing comfortable workstations and equipment.
- Anthropometry: Studying and measuring human body dimensions.
- Art: Ensuring accurate representation in portraiture and sculpture.
-
While the given range of 18-20cm is a good general rule, individual variations do occur.
