Anyone have 14' roll up doors?

Guys with 14' tall roll up doors, when your door is open and rolled up on the drum what is the diameter of the door on the drum? I'm assuming most drums are 12" diameter if not let me know. I'm trying to reverse engineer and build door brackets since the yahoo who built the shop didn't figure in for doors.

Approximately 15"-16"
