Definition:

  • “The study of the measurements
  • of the human body”
It is therefore that part of ergonomics which deals with body measurement, particularly size, strength and physical capacity. It was developed by Henry Dreyfus in the USA in the 1940/50’s.
  • To be universally effective, anthropometrics are used to describe the “user” or “target population” for a particular product.
  • Having data available on these groups takes the guesswork out of designing. Basic statistical information is used to interpret these data, e.g. Percentile study.
Today, designers and engineers rely on anthropometric data (body measurements) and experimental usability studies, to aid the process of making products easier to understand, safer to use, and better matched to the human body. The elderly, children, and disabled people are special groups with which ergonomic analysis may be concerned.

Percentile range
  • A “percentile” is a unit comprising 100th of the population.
  • Many products are designed to be used by the users who fall between the 5th and the 95th percentile.
  • Some products, e.g. washing machines, are designed for the 50th percentile and therefore all tend to be the same height.
  • Some products are made adjustable, so they ‘fit’ a bigger percentile range.

Consider a variety of products / scenarios, for example the cockpit of a plane (see link above) or the driving seat of a family car, or the safe amount of alcohol consumption when driving, and dietry requirements of people within different age groups and cultures.
