Industrial designers often take part in dimensioning activities that require anthropometric data. However, little is known about the data, tools and processes used. Hence, this study focused on documenting process. Telephone interviews were conducted with 82 industrial designers involved in the dimensioning of 4 types of objects (vehicles, furniture, tools, and sports equipment). Questions focused on data, tools employed, existing dimensioning activities and difficulties encountered. Results indicate that designers give preference to dated documentation and simple tools. The tools that integrate anthropometric data and recommendations related to the use of the product seem to be appreciated. Considered too costly and complex, Digital Human Models are seldom used. The formats of human representations varied according to the class of the product to be developed. Various artefacts are produced throughout the dimensioning process. The designers regularly take measurements of their own, on themselves or others. Potential areas for improvement are presented.
