There are individual differences in human body sizes. When designing products, it is important to remember that people come in many sizes and shapes. For example, if we design a doorway, we would need to design using dimensions of the widest and tallest people to ensure that everyone could walk through normally. Furthermore, if we design a chair, we should make the height of seat adjustable so that many individuals could use it comfortably. This paper describes ergonomic design methods considering individual variation in human body sizes focusing “percentiles” which are statistical measures of distribution. It is common practice to design for the 5th percentile female to the 95th percentile male. The 5th percentile female value for a particular dimension usually represents the smallest measurement for design in a population. Conversely, the 95th percentile male value may represent the largest dimension. The 5th% to 95th% range accommodates approximately 90% of the population.
