Produktiviteitsverhoging op grote schaal: Maatnormalisatie van kleding

The article contains a short review of a campaign, undertaken in Holland during the last 12 years to arrive at standardized sizes for women's and men's clothing. The first campaign was undertaken by a department store, the second one by the clothing industry.
The operational value of a sizing system depends on the value of three parameters which are not, of course, independent of each other: coverage of the system, number of sizes and average cost of alterations.
The basis of the standardization is furnished by measuring a sample of the population of customers and by measuring the fitting-tolerances of clothing.
The proposed sizing systems are:
a. Ladies' dresses — a two-dimensional system based on waist girth and length of back, containing 14 sizes and giving a coverage of 90%.
b. Men's suits — a system with a variable number of dimensions (2 to 4). The identification dimensions are waist girth, length of leg, hip girth and inclination of shoulder. The proposed system gives a coverage of 90% with 34 sizes. Both systems have been experimentally verified.
Stress is laid on the necessity of an international sizing standardization.
