How high should you mount a TV?
The golden rule of TV mounting is simple: the centre of the screen should sit at eye level when you are seated in your usual viewing position. For most sofas that means a centre height of roughly 100 to 115 centimetres above the floor, but your own eye height is what matters, not an average. Measure from the floor to your eyes while sitting comfortably, not perched upright, and use that number as your centre height. Then subtract half the screen height to find where the bottom edge will land. A 55 inch TV is about 68 centimetres tall, so with an eye height of 110 centimetres the bottom edge sits at about 76 centimetres, which is a comfortable height above most TV stands and media units.
Mounting too high is the single most common mistake, and it is usually caused by mounting above a fireplace or copying a showroom display. A TV mounted high forces you to tilt your head back for hours, which causes neck strain, headaches, and dry eyes from looking upward. The old advice to mount at eye level exists for a reason: your neck is designed to look slightly downward, not up. If your only option is above a fireplace, use a tilting or pull-down mount that brings the screen down and angles it toward you, and keep the tilt modest, since extreme tilt angles distort the picture and wash out the colours at the edges.
Measuring your seating eye height
Seat height varies a lot between a low lounge chair, a standard sofa, and a recliner, so measure in the seat you actually use most. Sit back naturally, look straight ahead at a blank wall, and have someone mark the wall at your eye level, then measure from the floor to the mark. Do it twice, once when you first sit down and once after ten minutes, because people sink into soft cushions over time. If several people of different heights use the TV, aim for the middle of their eye heights, or favour the person who watches most. For a household with a big height range, a full-motion mount that lets you fine-tune the height after installation is worth the extra cost.
| TV size | Screen height (16:9) | Centre at 110 cm eye height | Bottom edge |
|---|---|---|---|
| 43 in | 53.5 cm | 110 cm | 83.3 cm |
| 55 in | 68.5 cm | 110 cm | 75.8 cm |
| 65 in | 80.9 cm | 110 cm | 69.6 cm |
| 75 in | 93.3 cm | 110 cm | 63.3 cm |
| 85 in | 105.8 cm | 110 cm | 57.1 cm |
Viewing distance and screen size
Viewing distance and screen size belong together, because a screen that is too big for the distance overwhelms your field of vision and forces constant head movement, while one that is too small makes you squint at detail. For 4K TVs, a good rule is a distance of roughly 1.2 to 1.6 times the screen diagonal, which means a 55 inch TV suits 1.7 to 2.2 metres, and a 65 inch TV suits 2.0 to 2.6 metres. Older 1080p guidance of twice the diagonal is outdated for 4K, since higher resolution stays sharp closer up. If your room forces a short distance, choose a smaller screen or sit further back rather than mounting higher, since height never fixes a distance problem.
Mount types: fixed, tilt, and full motion
A fixed mount holds the TV flat against the wall and suits rooms where you always sit directly in front at the right height. It is slim, cheap, and tidy, but it gives no adjustment and makes cable access awkward. A tilt mount adds a few degrees of downward tilt, which helps when the TV must sit slightly above eye level, and it improves cable access a little. A full-motion or articulating mount swings out, swivels, and tilts, which suits corner installations, rooms with seating in several places, and anyone who wants to fine-tune height after mounting. Full-motion mounts cost more, stick out further from the wall, and need a very solid wall fixing, since the leverage of an extended arm is much greater than a flat mount.
Wall types and fixings
The wall matters as much as the mount. Solid brick and concrete take heavy-duty wall plugs or sleeve anchors and will hold almost any domestic TV. Timber stud walls need fixings driven into the studs themselves, not just the plasterboard, because plasterboard alone will not hold a large TV safely. Use a stud finder, mark both studs, and spread the mount across them. Plasterboard-only fixings such as toggle bolts can work for smaller TVs, but check their rated load and use several of them. Metal stud walls, common in newer flats, need specialist fixings and a lighter TV or a mount that spreads load widely. When in doubt, have a professional assess the wall, since a falling TV is dangerous and expensive.
Above the fireplace: the special case
Mounting above a fireplace is popular because it centres the room, but it usually puts the screen too high and too close to heat. Measure the mantel height first: if the mantel is already 120 centimetres, the screen centre will end up at 150 centimetres or more, which is far above seated eye level. Heat is the second problem, since rising hot air can damage electronics and void warranties, so check the manufacturer's clearance and use a mantel shelf to deflect heat if needed. A pull-down mount solves the height problem by lowering the TV to eye level when in use, but it adds cost and complexity. If the fireplace is the only wall, a pull-down mount is usually worth it.
Cables, power, and ventilation
Plan cables before you drill, not after. Decide whether cables will run in a surface trunking, behind a false panel, or inside the wall, and check local rules about running mains power inside walls, which usually needs proper conduit or a qualified electrician. Leave enough slack for a tilting or full-motion mount to move without pulling plugs out, and keep a spare HDMI cable in place for future devices. Ventilation matters too: TVs generate heat, so leave at least a few centimetres of airflow behind and above the set, and never enclose a TV in a tight cabinet without ventilation slots. A hot TV ages faster and dims sooner.
Glare, reflections, and viewing angle
Before fixing anything, test the position at different times of day. Sit in your viewing seat and look at the wall where the TV will go, checking for windows, lamps, and bright surfaces that will reflect in the screen. A matte screen tolerates more ambient light than a glossy one, but no TV looks good with a window directly behind the viewer. Curtains, repositioning a lamp, or a small swivel adjustment usually fix glare, but a fixed mount in a glare-prone spot cannot be adjusted later. Viewing angle matters too: most TVs look best within 30 degrees of straight on, and colours wash out beyond that, so angle the mount toward the main seating if the TV must sit off-centre.
Bedroom TVs: a different height
Bedroom TVs break the seated eye-level rule, because you watch lying down with your head on a pillow, which changes your sight line. For bed viewing, mount the centre slightly higher than seated eye height, often 120 to 140 centimetres, and use a tilt mount angled down toward the bed. Test by lying in bed and looking at the wall naturally, without propping yourself up, since the height that feels right when sitting up in bed is not the height that feels right when lying flat. Keep the TV far enough away that you are not craning, and favour a smaller screen than the living room.
Safety: children, pets, and earthquakes
A wall-mounted TV is far safer than one on a stand, but only if the mount is rated for at least the TV's weight and the fixings suit the wall. Check the VESA pattern, the four-hole spacing on the back of the TV, matches the mount, and use all the bolts supplied, tightened to the manufacturer's torque. In homes with small children, mount out of reach and secure any pull-down mount so it cannot be yanked. In earthquake-prone areas, add a safety strap as a second line of defence. Re-check fixings once a year, since houses settle and fixings can loosen, especially on stud walls.
- Measure seated eye height in your usual seat.
- Centre the screen at that height, not above a fireplace by default.
- Subtract half the screen height to find the bottom edge.
- Match distance to screen size before choosing height.
- Use fixings rated for your wall type and TV weight.
Mounting height is a measurement, not a guess. Measure your eye height, know your screen size, and use the calculator above to get a centre height and bottom edge you can mark on the wall with confidence, then choose a mount that suits your wall and your room's seating layout.
