A conventional home with 2x4 walls will consist of the stud which will be 3.5 inches thick two sheet of drywall each about 1/2 inch thick for a total of 4.5 inches. A 2x2 wall will be. Unless your building was built before 1980 and it is a mobile home it will have 2x4 walls.
A stud is a special piece of material. It's 1.5in. high x 3.5in. wide. It is not 8ft. (96in.) but 92.25in. long. A common 2x4 is actually 1.5x3. 5in.
Dimensional Sizing
We recognize such “sizes” as 2x4, 2x6, 4x4, 1x2, etc. This measurement refers to the thickness and width of the lumber, with the length varying. In reality, these measurements are not a true measurement of the lumber thickness or width. The true measurement of a 2x4 is actually about 1.5″ x 3.5″.
Also known as “studs”, wall studs are vertical framing members that help create wall structures. Typically pieces of wood or metal, wall studs are a fundamental part of the construction process as they form the underlying structure of your home.
One common check is to simply knock on the wall and see if it sounds hollow. Load-bearing walls are usually solid, whereas stud partition walls are hollow.
One of the easiest ways to distinguish between a stud wall and a solid wall is to look for visual clues. A stud wall typically consists of vertical wooden or metal beams (studs) lined up at regular intervals, with spaces in between.
If you see a third number (e.g. 2x4x8), that number is length. Thickness and width are measured in inches, while length is measured in feet. So 2x4x8 is two inches thick by four inches wide, and the board itself is eight feet long.
For the studs in a stud wall, timber is available in two common sizes including 75mm x 50mm or 100mm x 50mm of sawn timber, which is used for the studs as well as the other parts of the timber frame. Remember, these dimensions refer to the width and thickness, not the length.

Dimensional Lumber Explained:
In the past, when a timber was called a 2x4 [or "two-by-four"], it actually measured 2 inches by 4 inches. Now, most timber is milled and planed to give it a little more of a finished look, and a little more of a consistent size and profile.
Typical interior walls are framed with 2x4s. This makes walls about 4½ inches thick (3½ inches of wood covered on both sides by ½-inch-thick drywall).
Common studs are vertical members which transfer loads vertically to bottom plates. They are usually evenly spaced to suit loads, lining and cladding fixing.
2 x 4 framing is generally code compliant. Here at Medeek Design we typically only specify 2 x 4 studs @ 16" o.c. spacing, for small sheds and garages with a building widths less than 16 feet. All other larger structures are generally called out with 2 x 6 exterior studs @ 16" o.c. unless specified otherwise.
A piece of surfaced (sanded smooth) 2x4 lumber actually measures 1½ inches thick and 3½ inches wide. In rough-cut condition, a 2x4 is slightly less than 2 inches thick and approximately 4 inches wide. When wood is milled from a rough to a smooth surface, it loses about ¼-inch from each of its four sides.
Stud grade lumber is used in vertical applications such as load bearing walls. It is often sold in precision end trimmed (PET) lengths for typical construction uses; 92 5/8” for a 8' wall or 104 -5/8” for a 9' wall.

Unfortunately, depending on your living space and the construction of your home, the wall that you choose for your TV may not have studs. The good news is that you can still mount your TV despite the hollow walls with Mount-It's No Stud TV Wall Mount that hangs on your wall like a picture frame.
Most outlets and light switches will have a stud on the right or left side. The trim in your home, such as baseboards, crown molding, and other decorative finishing is usually nailed to a stud.
Process of Drilling into A stud
As you begin drilling, keep the drill perpendicular to the wall and apply steady, equal pressure. To avoid breaking the stud or allowing the drill to slip, choose a medium speed setting. Drill to the appropriate depth, which should be somewhat longer than the length of the screw.
Mounting Your TV to Wooden Studs
You can use a conventional flat TV wall bracket, making sure to drill into the centre of the studs for the mount to be as secure as possible.
