A workplace shall be adaptable for at least 90 % of the foreseeable population of users to fit for small females as well as for tall males (see Figure 1) in order to avoid forced body postures.
Figure 1: Chart of variation of the size of the working population in Europe (When used to calculate workplace heights, add 3 cm for wearing shoes.).
Anthropometric measurements indicate the variety of individual sizes of various parts of the body of the working population (see Figure 2). The measures for small women (5%) and tall men (95%) determine the required range of adaptability for workplaces and equipment.
Users differ not only in size. All users are individuals with specific characteristics such as male or female, left or right-handed, suffering from handicaps or chronic diseases.
