Walls built from 2x2 boards are not common in today's building methods, but some homes built in the early 19th century had 2-inch-wide walls. These thinner walls saved precious square footage in cramped living spaces. A wall built from 2x2s is not strong enough to support any load-bearing weight but is perfect as a partition wall. To frame a 2x2 wall, connect a top and sole plate to the existing adjoining wall and add studs, spacers and fire blocking as you work from right to left.
Step 1
Mark the location of the new partition wall on the ceiling. Snap a chalk line across the location.

Step 2
Use a stud finder to locate each ceiling joist along the chalk line. Mark the location of each joist with a pencil.
Step 3
Measure the length of the wall and cut a 2x2 board to this measurement. Use drywall screws to attach the 2x2 to the ceiling, using the chalk line and joist locations as a guide. Attach the 2x2 with screws at each ceiling joist location. Do not screw the 2x2 into unsupported drywall -- always screw into the ceiling joist. The 2x2 attached to the ceiling is called a top plate.
Step 4
Hang a plumb bob from the edge of the attached 2x2 on the ceiling in various locations. Lower the plumb bob weight to the floor and wait until the plumb bob stops moving. Have an assistant mark the location of the tip of the plumb bob on the floor at various locations. These marks will show the location of the bottom frame of the 2x2, or sole plate, of the wall.
Step 5
Lay a 2x2 on the floor at the plumb bob marks. Screw the 2x2 into the floor with drywall screws.
Step 6
Measure the distance between the top plate and the sole plate on the right side of the partition wall. Add 1/8-inch to this measurement and cut a 2x2 to this measurement. The extra 1/8-inch will ensure a snug fit between the two plates. Screw or nail this vertical 2x2 board, called a stud, to the adjoining existing wall. Toe-nail the stud to the top plate and the sole plate.
Step 7
Determine the distance between the top plate and the sole plate on the left side of the partition wall. Add 1/8-inch to this measurement and cut a 2x2 to this measurement. Attach the stud to the adjoining existing wall and the two plates.
Step 8
Cut two 16-inch sections of 2x2 lumber. These sections are called spacers. Go back to the right side of the partition wall. Nail or screw one 16-inch spacer to the top plate. Attach the other 16-inch spacer to the sole plate. These two 16-inch spacers between the studs will make the wall more secure and ease the later installation of the drywall boards to the 2x2s.
Step 9
Measure the distance between the top plate and the sole plate next to the 16-inch sections. Again, add 1/8-inch to this measurement and cut a 2x2 to this measurement.
Step 10
Place the stud between the top plate and sole plate and next to the 16-inch spacers. Use a rubber mallet to lightly tap the stud into place. Toe-nail the 2x2 framing member to the top plate and sole plate.
Step 11
Cut two more 16-inch sections of 2x2 lumber. Attach these to the top and sole plates, next to the vertical stud you just installed.
Step 12
Measure the distance between the top plate and the sole plate next to the 16-inch sections. Again, add 1/8-inch to this measurement. Cut the stud and toe-nail it to the top and sole plates. Continue this procedure until you reach the left side of the wall. The final set of spacers will most likely not measure 16 inches so measure between the two studs and cut according to size.
Step 13
Go back to the right side of the partition wall. Measure the width between the first two studs approximately one-third and then two-thirds of the length down the wall. The measurements will most likely be 16 inches or an approximation. Cut two sections of 2x2 and toe-nail the sections in between the two studs at one-third and two-thirds down the wall. These sections of wood are called fire blocking and are required under some building codes. They also add stability to the wall.
Step 14
Continue measuring and installing the fire blocking across the entire wall.
