Tab Rough Opening
Industry Standard is that you add at least 2" to the overall dimension of the door size, to determine your RO. For example, if you order (1) 30"W x 80"H size door, your RO needs to be at least 32"W x 82"H for a single door application. If you are ordering for a double door application, and want to use (2) 30"W x 80"H size doors inside your one opening, your RO needs to be at least 62"W x 82"H.
