A wall-mounted television looks tidier and frees a surface. It also fixes the height permanently, and the most common mistake in home cinema is mounting too high, which means years of looking up at a screen and a picture that is worse because of the viewing angle.
The short answer
The centre of the screen should sit at roughly eye level when you are seated, which for most sofas means the middle of the television around 100 to 110 centimetres from the floor. That is considerably lower than most people mount. Above a fireplace is almost always too high, and it is the single most common regret.
Getting the height right
Sit where you actually watch. Have someone hold a tape measure and note the height of your eyes from the floor: for most people on a normal sofa that is around 100 to 115 centimetres. The centre of the screen wants to be at about that height, or very slightly below.
That is lower than instinct suggests, and it is lower than most installations. The reason it matters: looking up at a screen for two hours is uncomfortable for your neck, and viewing angle degrades the picture on many panels, washing out contrast and shifting colour.
The fireplace question comes up constantly and the honest answer is that it is too high in almost every room. If the layout forces it, a full-motion mount that tilts the screen down is essential rather than optional.
Measure your seated eye height
Sit where you watch, measure from the floor to your eyes. This number drives the whole decision.
Mark the screen position on the wall with tape
Outline the television at the height you are considering. Live with the tape for a couple of days before drilling anything. People frequently discover the position is wrong once it is marked out.
Check the viewing distance
A rough guide for 4K is a distance of about one and a half times the screen width. Too far and you lose the benefit of the resolution; too close and you see the pixel structure and have to move your eyes across the screen.
Find out what the wall is made of
Solid masonry takes a mount easily with the right fixings. Plasterboard needs the studs, and a heavy television on plasterboard fixings alone will come off the wall eventually. This determines whether mounting is even sensible.
Plan the cables before mounting
Cables to a wall-mounted television are the part everyone forgets. Decide whether they run in trunking, inside the wall, or down to a unit below, and check you can reach the ports once it is up.
Check the mount's VESA pattern and weight rating
The bolt hole spacing on the back of the television must match the mount. Weight rating should have comfortable margin over the television’s actual weight.
Choose the mount type deliberately
Fixed is cheapest and closest to the wall. Tilting helps if the television must go higher than ideal. Full-motion lets you angle it toward different seats and reach the ports, and costs the most.
Consider a stand with the right height instead
A low media unit that puts the screen centre at eye level achieves the same result, costs less, requires no drilling, and leaves the cables accessible. For a lot of rooms it is the better answer.
Tape the outline on the wall and leave it for two days. It costs nothing, it takes five minutes, and it is the single best way to avoid a permanent mistake. A surprising number of people move their planned position down by twenty centimetres after seeing it marked out.
Stand against wall mount
Advantages
- Stand: no drilling, no commitment, easy to move
- Stand: cables stay accessible, which matters more than people expect
- Stand: usually puts the screen at a sensible height by default
- Wall mount: tidier, frees the surface
- Wall mount: safer in a house with small children, if properly fixed
- Wall mount: allows a larger screen in a small room
Drawbacks
- Stand: takes floor space and needs a unit wide enough
- Stand: a television on a unit can be pulled over by a child
- Wall mount: permanent, and the holes stay
- Wall mount: cables need planning, and reaching the ports is awkward
- Wall mount: tempts people to mount too high
- Wall mount: needs the right wall and the right fixings
Televisions on furniture tip over and injure children, and it happens more often than people realise. If you have small children and are using a stand, use the anti-tip strap that came with the television and fix it to the wall or to the furniture. If you are mounting on plasterboard, find the studs; plasterboard fixings alone are not adequate for a large television.
The fireplace problem
It is the tidiest-looking place in many rooms and it is almost always too high. The screen centre ends up thirty or forty centimetres above ideal, which means looking up for the whole evening, and heat from a working fire is bad for the electronics.
If the room genuinely offers nowhere else, use a full-motion mount that pulls out and tilts down, and check the temperature above the fireplace when the fire is running. A pull-down mount that brings the screen to eye level for viewing and returns it flat afterwards exists for exactly this situation, and it is expensive but it solves the problem properly.
How high should a TV be mounted?
The centre of the screen at roughly seated eye level, typically 100 to 110 centimetres from the floor. That is lower than most people mount and it is the most common regret.
Is above a fireplace too high?
Almost always. If the layout forces it, a full-motion mount that tilts down is essential, and check the temperature when the fire is lit.
Can I mount a TV on plasterboard?
Only into the studs. Plasterboard fixings alone are not adequate for a large television, and a mount that fails brings the television down with it.
How far should I sit from a 4K TV?
Roughly one and a half times the screen width. Further and the resolution is wasted; much closer and you see the pixel structure.
Is a stand safe with small children?
Only with the anti-tip strap fitted, which comes with most televisions and is rarely used. Televisions pulled off furniture cause serious injuries every year.
The bottom line
Measure your seated eye height and put the centre of the screen there, which is lower than instinct suggests. Tape the outline on the wall and live with it for two days before drilling. And if you use a stand, fit the anti-tip strap, because that is the part of this decision that actually matters.
