The basic steps for mounting a TV safely

Attaching a TV to a wall mount means securing your television to a bracket that is bolted into the wall studs behind your drywall. The TV itself connects to the bracket with bolts that thread into the back of the TV. The bracket holds the weight of the television and transfers that weight to the studs, which are the wooden or metal frame members that support your walls.

The process has three parts: finding and marking the studs, installing the bracket into those studs, and then attaching the TV to the bracket. Most people can do this with basic tools — a stud finder, a drill, a level, and a wrench or socket set. The whole job usually takes one to two hours if you have the right bracket for your TV model and the right fasteners.

Key Takeaways

  • A wall mount bracket must be bolted into the wooden or metal studs behind your drywall, not into drywall alone, because drywall cannot support the weight of a television.
  • The TV connects to the bracket using bolts that thread into threaded holes on the back of the TV, which are standardized in a pattern called VESA.
  • You need a stud finder to locate the studs, a level to make sure the bracket is straight, and a drill to create pilot holes before inserting the bolts.
  • If you cannot find studs where you want to mount the TV, you can install a horizontal wooden beam (called a mounting rail) between two studs to create a mounting surface.

Why the bracket must go into studs, not drywall

Drywall is a thin layer of gypsum board that covers the studs. It is not strong enough to hold the weight of a television. A 55-inch TV weighs between 40 and 60 pounds, depending on the model. If you bolt a bracket into drywall alone, the bolts will eventually pull through the drywall and the TV will fall.

Studs are the vertical wooden or metal members that form the skeleton of your wall. They are typically 16 inches apart, measured from the center of one stud to the center of the next. A bracket bolted into at least two studs can safely hold a TV. This is why the first step is always to find the studs with a stud finder.

Finding studs and marking the bracket location

A stud finder is a handheld device that detects the density change between drywall and wood or metal. You run it across the wall until it beeps or lights up, which tells you where a stud is. Mark that spot with a pencil. Then move the finder to the right until it stops beeping — that is the edge of the stud. Mark that spot too. The stud is the space between those two marks.

Once you have found the studs, hold the bracket up to the wall at the height you want it. Use a level to make sure the bracket is perfectly horizontal — if it is tilted, the TV will look crooked and may slide on the bracket. Mark the bolt holes on the wall with a pencil. These marks show you exactly where to drill.

Check that at least two of the bolt holes will go into studs. If they will not, you need to either move the bracket left or right, or install a horizontal mounting rail between two studs first. A mounting rail is a piece of wood or metal that spans between two studs and gives you a wider surface to bolt the bracket into.

Drilling pilot holes and installing the bracket

Before you insert the bolts, drill a pilot hole at each mark. A pilot hole is a small hole that guides the bolt and prevents the wood from splitting. Use a drill bit that is slightly smaller than the bolt diameter — if your bolts are 3/8 inch, use a 5/16-inch bit. Drill straight into the wall until the bit reaches the stud.

Insert the bolts through the bracket holes and into the pilot holes in the studs. Use a wrench or socket set to tighten them. Tighten in a crisscross pattern — if the bracket has four bolts, tighten the top-left, then bottom-right, then top-right, then bottom-left. This keeps the bracket from tilting as you tighten. Do not over-tighten; stop when the bracket is snug and does not move.

Once the bracket is installed, use the level again to confirm it is still horizontal. If it has shifted, loosen the bolts slightly and adjust it, then tighten again.

Connecting the TV to the bracket

The back of your TV has a pattern of threaded holes. This pattern is called VESA, which stands for Video Electronics Standards Association. Common VESA patterns are 100x100 (holes 100 millimeters apart), 200x200, 300x300, and 400x400. Your bracket must match your TV's VESA pattern.

The bracket comes with bolts sized for your VESA pattern. Hold the TV upright (you may need a second person) and align the bolt holes on the bracket with the threaded holes on the back of the TV. Insert the bolts and tighten them by hand first, then use a wrench to snug them. Again, tighten in a crisscross pattern and do not over-tighten.

Once the TV is bolted to the bracket, the bracket supports the full weight. Test this by gently pushing on the TV from different angles. It should not move or flex. If it does, check that all bolts are tight and that the bracket itself is still bolted securely to the studs.

Cable management and final checks

After the TV is mounted, route your cables — HDMI, power, ethernet, or whatever you use — behind the TV or down the wall. Many people use a cable raceway, which is a plastic or metal channel that hides the cables and keeps them organized. Raceways are optional but make the installation look cleaner and protect cables from damage.

Plug in the power cable and turn on the TV to confirm it works. Check that the picture is level and that the TV does not tilt or shift when you adjust the angle with the bracket controls. If your bracket is tilting or the TV is not level, turn off the TV, unplug it, and loosen the bolts to adjust the bracket position.

What to do if you cannot find studs where you want to mount

If the studs in your wall do not line up with where you want the TV, you have two options. The first is to move the TV location left or right until the bracket holes align with studs. The second is to install a horizontal mounting rail between two studs.

A mounting rail is a piece of wood (usually 2x4 or 2x6) or a metal bar that you bolt between two studs. You then bolt the bracket to the rail instead of directly to the studs. This gives you flexibility to position the bracket anywhere along the rail. Installing a rail requires cutting into the drywall, removing a section, bolting the rail to the studs, and patching the drywall afterward. This is more involved than a straightforward bracket installation, but it solves the stud alignment problem.

Frequently Asked Questions

Can I use toggle bolts or drywall anchors instead of bolting into studs?

No. Toggle bolts and drywall anchors are rated for much lighter loads — typically 20 to 50 pounds total. A TV and bracket together weigh more than that, and the bolts will eventually pull through the drywall. Always bolt into studs.

What if my TV does not have threaded holes on the back?

Some flat-screen TVs have a VESA pattern of threaded holes, and some have a pattern of unthreaded holes. If your TV has unthreaded holes, the bracket bolts go through the TV's holes and then thread into the bracket itself. Check your TV's manual to see which type you have, and buy a bracket designed for your model.

How do I know if my bracket is rated for my TV's weight?

Every bracket has a weight rating printed on the box or in the manual. It will say something like "rated for TVs up to 80 pounds." Weigh your TV (the weight is usually on the back or in the manual) and make sure the bracket rating is at least that weight, preferably higher.

Do I need to turn off the TV before mounting it?

Yes. Turn off the TV, unplug it, and wait a few minutes for it to cool down before you handle it. This is safer for you and for the TV. Do not plug it back in until it is fully mounted and all bolts are tight.

What if the bracket is crooked after I tighten all the bolts?

Loosen all the bolts slightly — just enough that the bracket can move — and use the level to adjust it. Tighten the bolts again in a crisscross pattern. If it keeps tilting, the wall studs themselves may not be perfectly vertical, which is common in older homes. Tighten the bolts as much as you safely can and accept a small tilt, or consider a different mounting location.
