The sample size was calculated based on the assumption that a relative accuracy of 10% is sufcient for the 5th and 95th percentiles and an empirical CV value of 25. It is conventional to refer to the 5th percentile (short) female and the 95th percentile (tall) male to establish a range of human dimensions that accommodates 90% of the population. A Clearance is typically set by using the 95th percentile male for a given dimension. For the purpose of ergonomics, the 95th percentile represents the upper boundary for design and effectiveness considerations.

The measurements made in this study were used to develop 5th, 50th, and 95th percentile, quarter- and half-scale, male and female mannequins. For a mixed male/female population, this dimension is 41 inches. In these cases, as a fallback, average elbow height can be used, i.e., the 50th percentile. What these numbers tell us is that there is indeed a significant anthropometric difference between military and civilian databases. The distinction is that often one must do something with an object, not just touch it. The illustration at right shows both stature and elbow heights for the 5th percentile female and the 95th percentile male. What are physical demands analysis reports actually used for? 95th percentile is a series of measurements that 95 percent of the population will fall within. Thus, a workbench or a standing platform that adjusts 10 inches accommodates 90% of the population.
