Tips for framing interior walls include maintaining proper spacing between studs, conserving space by using two-by-four studs and plates, using lighter headers over doors and making adjustments for adjacent walls that are not plumb. While the interior walls you add after the construction of a home are not load-bearing, avoid shortcuts that affect the rest of the project.
Space the studs on 16-inch centers to facilitate installation of drywall or other 4-foot materials. Mark the header and footer of the wall 15 1/4 inches from the adjoining wall. Make subsequent marks every 16 inches along the entire length of the wall. Place a second mark 1 1/2 inches beyond each of the first mark and place an “x” between each set of marks, indicating the location of the stud.
Two-by-four framing provides sufficient support for interior walls while reducing the square footage occupied by the walls. Use of these materials also reduces the cost of the project. If walls contain plumbing or mechanical equipment, it is sometimes necessary to increase the framing members to two-by-sixes.
The headers over doors and windows on load-bearing walls are usually made from four-by-twelve beams. However, interior walls do not require the heavy support. In most instances, two two-by-fours placed side-by-side provide sufficient support.
