Calculates the rough opening based on the size of the component to be installed and the recommended amount for frame opening shims.

Standard doors are 6ft 8in. You should consider adding 3/4in. for the jamb, 3/4in for finish flooring, 3/8in for underlayment, and 3/4in for adjustment at the top of the door. The top of the trimmer (the bottom of the header) needs to be about 83in above the subfloor. This height can vary slightly in a remodeling project depending on what's happening with the existing floors. Door widths vary, but an easy way to size the rough opening is to use the door width plus 5in as the distance between the king studs.

-Width: Width of door.

-Height: Height of door.

-Add to Width: Amount to be added to the width of the opening to allow leveling for plumb installation.

-Add to Height: Amount to be added to the height of the opening to allow leveling for plumb installation.

-RO Width: Rough opening of the width to allow for leveling.

-RO Height: Rough opening of the height to allow for leveling.

-Same as Door Opening but applied to a window.

Calculate the rough opening for a window that is 4ft 8in square with a recommended additional 2in added to each side and a door that is 3ft wide, 6ft 8in tall with a recommended 1&1/2in to be added to each side for shimming purposes and 3in for height.
