A 3D anthropometric sizing analysis system based on North American CAESAR 3D scan data for design of head wearable products.

•2299 heads of the Civilian American and European Surface Anthropometry Resource (CAESAR) were edited for measurement.•30 anthropometric head and face dimensions were measured.•A 3D Anthropometric Sizing Analysis System (3D-ASAS) was developed and applied in head-wearable product design.•A sizing system of a head-wearable product can be easily found by product designers through simple use of the 3D-ASAS.
