But my hands are the smallest of any woman I’ve ever met and… never mind. 
6" span from thumb to little finger on my left hand. Can’t span my right hand any more due to arthritis but IIRC it was a little bigger, being the dominant hand. Oddly, looking up statistics that’s supposedly only slightly smaller than average but they must have been measuring some strange women, because mine are noticeably small - can’t make an octave on a piano, can’t hold a pint glass easily, etc.
