How do I properly measure my Banjo Drumhead?
The diameter of a banjo head is measured inner-flesh-hoop to inner-flesh hoop of the head (you'll need to take the head off to take accurate measurement...flip the head over to measure the inner dimension(ID)). The measurement must be exact as we go off 1/16" increments.
The Collar or 'Crown' height is measured top of the flesh-hoop (aluminum hoop of the head) to top of the playing surface of the head. Standard heights are: low-3/8", medium-7/16", high-1/2".
