How to Mount a TV on the Wall

A wall-mounted TV clears the clutter, opens up the room, and looks like it came with the house — when it’s done right. Miss the studs or under-buy the hardware, though, and a $1,200 television becomes a very expensive way to punch a hole in your drywall. Here’s how to hang it so it never moves.

What you’ll need

• TV wall mount — rated for your screen size and weight; fixed, tilting, or full-motion (see the table below)
• Stud finder and tape measure — the tape sets your height; the stud finder keeps the TV on the wall
• A level — a 2- to 4-ft. bubble level, or a laser level for a solo hang
• Pencil or marker — to mark stud centers and bolt holes
• Cordless drill/driver — a DeWalt, Milwaukee, or Ryobi 18/20V drill has the torque for lag bolts
• Drill and masonry bits — a wood bit to pre-drill studs, a masonry bit if you’re going into brick or block
• Socket and ratchet or driver — most mounts use lag bolts with a hex head, not a Phillips
• Lag bolts and mounting hardware — the mount usually includes them; upsize if yours look flimsy
• Heavy-duty wall anchors — only if you truly can’t hit studs, or for concrete/brick installs
• Screwdrivers — for the smaller machine screws that fasten the bracket to the TV
• Safety glasses — drilling overhead sends dust and grit straight down at your eyes

Step 1: Pick the right mount and check your TV

Before you buy anything, flip your TV face-down on a padded surface and read two numbers off the back or the manual: the VESA pattern (the spacing of the four threaded holes, like 200×200 or 400×400 mm) and the weight. Your mount must match the VESA holes and be rated well above the TV’s weight — buy for the screen size, not just the pounds. Fixed mounts sit flush and cheap; tilting mounts help with glare and higher placement; full-motion arms pull the screen out and swivel, which is great for corners but puts far more leverage on the wall, so those especially demand solid studs.

Height tip: the center of the screen should land roughly at seated eye level — about 42 in. from the floor for a typical living room. Mount it “fireplace high” and everyone in the room spends the night with a sore neck.

Step 2: Find the studs and mark your line

Run your stud finder across the wall and mark both edges of each stud, then split the difference for dead center — studs are usually 16 in. apart on center. Confirm by driving a small finish nail or a thin bit into the mark; you should feel firm wood, not empty give. Decide your mounting height, then use a level to draw a light, perfectly level reference line where the top of the wall plate will sit. On a wide TV you want to anchor into two studs if you possibly can.

Step 3: Attach the bracket to the TV

Most mounts split into two parts: a wall plate and the arms (or rails) that bolt to the TV. Fasten the arms to the back of the screen now, while it’s flat and easy to reach, using the machine screws sized for your VESA holes and a screwdriver. Snug them firmly but don’t crank — you can strip the plastic bosses inside the TV. If the kit came with spacers, use them so cables still clear the back panel. Set the TV aside somewhere safe.

Common mistake: using screws that are too long. Overlong VESA screws can bottom out against the circuit board and crack it. If the included screws don’t match, take the old ones to your local hardware store and match the thread exactly — don’t force a close-enough substitute.

Step 4: Drill and bolt the wall plate

Hold the wall plate to your level line, mark the bolt holes over the stud centers, and pre-drill each one with a bit slightly smaller than the lag bolt’s shank so the threads bite hard. Then drive the lag bolts through the plate into the studs with a socket and ratchet until the plate is rock-solid and flush — snug, not spinning. Recheck level before the last turn. Into brick, block, or concrete: switch to a masonry bit and hammer-drill setting, and set proper sleeve or wedge anchors rated for the load. Grab the mounted plate and pull hard — put your weight on it. It should not budge.

No studs where you need them? On drywall alone, never trust plastic butterfly anchors with a heavy TV. Use heavy-rated toggle bolts or a plywood cleat spanning two studs. If you’re dealing with metal studs, plaster-and-lath, or you’re just not sure the wall can take it, that’s the moment to call a pro rather than gamble the TV.

Step 5: Hang the TV and level it

This is a two-person move for anything over about 40 in. — one to lift, one to guide. Line the TV’s arms up with the wall plate and set them into the hooks or channel; you’ll usually feel or hear it seat. Most mounts have a locking screw, safety tab, or retention cord at the bottom — engage it so the TV can’t be bumped off the wall. Set a level on top of the screen and use the mount’s built-in adjustment to correct any tilt. A little play in the wall plate’s slots is normal and exactly what it’s there for.

Step 6: Manage the cables and finish up

Plug in your HDMI and power cables and dress them so they don’t dangle. A cable management kit — raceway, clips, or an in-wall pass-through — hides the run and makes the whole install look intentional. If you route cables inside the wall, only low-voltage HDMI and speaker wire belong there; running standard power cord through the wall is a code and fire hazard, so use a rated in-wall power kit or add an outlet behind the TV instead. Power it on, confirm the picture, and give the TV one last gentle test for wobble.
