People exhibit quite remarkable variety in body size as well as in most other characteristics. The tallest person is nearly 9 ft tall and the shortest is under 2 ft tall and that doesn't include babies and children. The average pygmy is more than one foot shorter than the average person from the Sudan.

Such are the extremes of the world population, but we all know from everyday experience that there are large individual differences between people even in a more restricted population like, for example, office workers.

A population of office workers may include teenagers who have not yet grown fully, people from a wide variety of ethnic backgrounds, pregnant women, people in wheelchairs and so on. Who then do we design for? The general answer is of course the user but in practice, as for clothing, it is usually not practical or economic, to have standard designs for ALL the users.
