Which term describes the measurement of the size, proportions, and range of motion of the human body?

• A. The measurement of the size, proportions, and range of motion of the human body.
• B. The study of how end-users interact with products.
• C. The process of testing product durability.
• D. The method of material selection

Answer: (A)

Anthropometrics is the measurement of the size, proportions, and range of motion of the human body. In design and technology, this data is used to ensure products fit a wide range of users—setting things like chair height, desk clearance, and where controls should be placed so they’re comfortable and accessible. The other descriptions refer to different ideas: studying how end-users interact with products is about ergonomics or human factors, testing product durability is about reliability and strength, and material selection is about choosing materials for performance and cost. So the term that captures measuring body size, proportions, and movement is anthropometrics.
