Anthropometric Measurements: Body Shape and Dimensions

Anthropometric measurements are those that characterize human body dimensions (size and shape). These measurements are primarily of bone, muscle, and adipose tissue (fat). The word combines the Greek root words anthropos (human) and metron (measure).

Typical Anthropometric Measurements

• Height, standing
• Height, sitting
• Weight
• Waist circumference
• Waist-to-hip ratio
• Waist-to-height ratio
• Body mass index, or BMI (weight in kilograms divided by square of height in meters)
• Grip strength
• Skinfold body fat measurement

Scientific Research

Anthropometric measurements are valuable in scientific research because, if recorded using standardized methods, they are objective and not prone to the perceptions or opinions of the scientists involved.

In longitudinal studies, certain basic measurements like waist circumference can reveal risk factors for age-related illnesses like heart disease or cancer.

Ergonomics Design and Industry

In industrial applications like ergonomics, anthropometric measurements help manufacturers create furniture that is tailored to the human body.

In automotive design, anthropometry involves taking standard measurements for average adult drivers to test cars and other vehicles for the effectiveness of their safety systems.

Ongoing measurements are needed as populations change in height, weight, and other dimensions. As a population gets taller overall, as often happens with better nutrition, the items used in everyday life must be able to accommodate taller people.

Similarly, as the population includes more and more people who are overweight or excessively overweight, designs for everything from clothing to chairs to average weight capacity of elevators may need to be adjusted.

If childhood weight trends rise, items for children need to include the consideration that more of them may be overweight. Some populations of children have earlier growth spurts and puberty, which needs to be a consideration when designing for those age groups.

Anthropometric Databases

There are many databases of anthropometric data that has accumulated over years to decades. Originally, these were often collected by the military.

• Army Anthropometric Survey (ANSUR): Published in 1988, it has hundreds of different measures for all, although it is weak for some target populations and high BMI-individuals. That makes sense as it was collected originally from troops who were required to keep under certain body weight; the groups would have included far fewer people assigned female at birth than people assigned male at birth as well.
• NHANES: The National Health and Nutrition Examination Survey includes body measurements for infants and toddlers through adolescents and adults. Weight, standing height, upper-leg length, upper-arm length, mid-upper arm circumference, waist circumference, and sagittal abdominal diameter are measured for most subjects, with head circumference and recumbent length added on for infants. These measures change from year to year.
• CAESAR: Civilian American and European Surface Anthropometry Resource have both 3-D body scan measurements as well as traditional 1-D measurements of thousands of individuals ages 18 to 65 from 1998-2000. It is used in many industries for design. If you are designing a chair, a desk, or a car, you would want access to these measurements so you can ensure your product will work for most people.
