How to measure a banjo head?
Measure your banjo for the right head width. Your banjo’s rim might be out of round a bit, so take in 3 diameter measurements at least at different points on the outside of the banjo’s tone ring or rim top. Use the normal diameter to the closest 1/16″ to get the right size.
Most of the modern stringed instruments utilize an 11″- diameter head. The manufacturers of classic open-back banjos normally use 11″ or 12″ heads. The vintage banjos may have a wide range of rim diameters from 10″ to 12″.
Picking the right Crown Height
The height of the crown is the vertical gap from the highest point of the head’s mounting band to the top surface of the head. A banjo with a flathead tone ring or a flat-topped banjo requires a medium or high crown head. Remember, a banjo with an archtop tone ring needs a low crown head. The right crown height keeps the banjo’s tension hoop from pulling down too far and guarantees the band will not be so high as to obstruct the strings.
There is not much difference on how to measure a banjo head, for example, a high crown head is ½” and a medium crown head is 7/16″. It is measured from the highest point of the Mylar edge to the highest point of the aluminum edge of the banjo head. When the head has extended, it is hard to rely upon that measurement for accuracy so it is ideal to know what you need as per manufacturing specifications.
The Goodtime Series banjos, paying little mind to age, will always take a high crown banjo head regardless of which head type you pick. It will allow you to install it simply and get it tightened down enough for the right installation.
All the upper line Deering banjos made before 2006 will take a high crown head, paying little mind to the style of head. You can use a medium crown but it will take more time to reach over the edge/tone ring to get to the proper tightness. The high crown has more space to slip over without bottoming out on the hooks; i.e. having the option to get the head tight enough before you run out of string to do so on the hook.
On the other hand, the upper line banjos made on or after 2006 take a medium crown head. It’s because the updated 2006 tone ring has a more adjusted top edge, which doesn’t need the additional depth of crown height.
All the upper line 12″ rim banjos will require a low crown head and all Goodtime 12″ rim banjos will require a medium crown head.
