One of the most crucial elements of framing walls is getting
the rough openings right. Items that determine what the
height of One of the most necessary elements of framing walls is getting
the rough openings right. Items that determine what the
height of your opening will be are floor finishes and the
use of underlayment. Door widths will stay continuous with the
size of a ordinary door.
In new construction most doors are hung after the floors are
installed. This allows flooring contractors (tile, hardwood,
vinyl, laminate) to lay their flooring merchandise without
making tricky cuts around door jambs. It also makes for a
neat and clean door installation. Exceptions to this are
carpeted floors. Doors are hung before the carpeting is
laid. When doors are hung in carpeted areas, it is a good idea
to shim them up 1/2″, putting a shim underneath each jamb leg.
This does away with the need to cut the doors down after the
carpet is installed.
For a 6′ 8″ high door (80 inches) I like to frame my rough
opening height at 82 3/4″. This allows room for all the
situations cited above. If your header material is a
double 2×12, keeping it to the top plate will give you that
height.
Rough openings for door widths are finelooking much standard. The
rough opening width is 2 inches wider than the door itself.
this allows room for the door jambs which are normally 3/4″
thick. This gives you approximately 1/2″ of play and shim
room when installing a prehung door. For a 36″ door (3′ 0″)
the rough opening width would be 38″. Here are the most
common door sizes and their rough openings.
Door Size Rough Opening Size
2′ 0″ x 6’8″ -26″ x 82 3/4″
2′ 2″ x 6’8″ -28″ x 82 3/4″
2′ 4″ x 6’8″ -30″ x 82 3/4″
2′ 6″ x 6’8″ -32″ x 82 3/4″
2′ 8″ x 6’8″ -34″ x 82 3/4″
2′ 10″x 6’8″ -36″ x 82 3/4″
3′ 0″ x 6’8″ -38″ x 82 3/4″
To figure the rough opening for double doors or french
doors, take the door size times 2 and add 2″. The most
common sizes for exterior doors are the 2’8″ and the 3’0″
doors. The 2’8″ is commonly used for the back door and the
access door from the garage. That size door for exterior use
is being employed less these days because of the size of
appliances and furniture. Exterior doors with sidelights and
sliding patio doors rough openings vary from manufacturer to
manufacturer. These ought to be verified and gotten from the
supplier.
Getting the rough openings right the introductory time keeps the
sawzall in it is carrying case and having to alter the
opening after the walls are drywalled and painted.
