ABSTRACT: Left-handers are reputed to be shorter than right-handers. However, previous research has confounded handedness direction (left-versus right-handedness) with handedness strength (consistency with which one hand is chosen across a variety of tasks; consistent-versus inconsistent-handedness). Here, we support a relationship between handedness strength, but not direction, and stature, with increasing inconsistent-handedness associated with increasing self-reported height.
