A need was identified for data concerned with maximum possible and maximum comfortable angular displacement of the thumb. These measures, along with thumb reach data, were collected from a sample of 105 subjects. It was found that thumb reach was not correlated with either maximum or most comfortable degree of angular displacement. In addition, angular displacement was not correlated with age. Design guidelines for angular displacement of the thumb are provided.
