One of the most common requests from the recent survey was for anthropometric data sources. Unfortunately, most data sources are proprietary and/or costly.
Here are some of the leading data and measurement providers:
Civilian American and European Surface Anthropometry Resource Project—CAESAR
Here are links to a few publicly available sources, but please comment if you know of more modern and diverse data sets that are available:
U.S. Military Anthropometric Data Sets
NASA Anthropometric Guidelines (based on American males and Japanese females, 2000)
Anthropometric Data of Children
UPDATE: The Human Factors and Ergonomics Society has recently published Guidelines for Using Anthropometric Data in Product Design that discusses methods, resources and practices for designing for the human body.
