Generation Gap: How Gen Z, Millennials and Boomers Choose TV Units

A television unit is sized by the screen and positioned by the eye. Screen size is quoted as a diagonal, which tells you almost nothing useful about the furniture underneath, so the first job is converting it into a width. A 55 inch screen in the standard 16:9 shape measures roughly 122cm across, which means the unit beneath it should be at least 140cm wide if the television is not to look as though it is balancing on a plinth.

The second decision is height, and it is the one that causes physical discomfort rather than visual awkwardness. Seated eye level in a normal living room falls somewhere between 100cm and 120cm from the floor, and the centre of the screen should sit at or a little below that line. Every centimetre above it asks the neck to tilt back for the length of a film.

Key findings at a glance

• Screen width, not diagonal, sets the minimum unit size. In 16:9 format, the screen width is approximately 0.87 times the quoted diagonal.
• A unit should be wider than the screen by at least 20cm in total, and looks better with more.
• Seated eye level generally falls between 100cm and 120cm, so the centre of the screen belongs at or slightly below that height.
• Unit heights of 40cm to 55cm suit most large screens in a room where people watch from a sofa.
• A soundbar needs 8cm to 12cm of clear height on the shelf it sits on, and must not block the screen’s lower edge or its remote sensor.
• Domestic storage furniture sold in the UK is covered by BS EN 14749, and any tall or top heavy unit should also be secured to the wall in homes with young children.
• No public dataset records how UK households of different ages choose television furniture, so the differences here are read from room layouts and equipment rather than presented as measured data.

Converting a screen size into a piece of furniture

Televisions are sold on the diagonal of the panel, while furniture is sold on width. The conversion is straightforward geometry for any 16:9 screen, and it removes the guesswork entirely. Add a couple of centimetres for the bezel and the stand feet, which on many large screens sit close to the outer edges rather than in the centre.

Check the stand feet before ordering. Where the feet sit at the extreme corners of a large screen, the usable top surface of the unit has to be wider than the panel itself, and a pedestal stand in the centre needs a solid area of top rather than a slatted or glass shelf with a gap in the middle.

Height, eye level and the fireplace problem

Comfortable viewing depends on the relationship between the centre of the screen and the eyes of the person watching. Sit on your sofa and measure from the floor to your eyes: for most adults on a seat of 45cm, that lands somewhere between 100cm and 120cm. Then work backwards. On a 50cm unit, a 65 inch screen has its centre at roughly 90cm, which is slightly below eye level and comfortable. Put the same screen on a 90cm sideboard and the centre climbs to about 130cm, which is above eye level for almost everyone.

This is why televisions mounted above fireplaces so often disappoint. The mantel forces the screen up, and the neck compensates for the whole film. Where a chimney breast is the only sensible wall, the workable compromise is a lower profile unit sitting in the alcove line with the screen wall mounted just above it, rather than a full height installation above the mantel. Ranges of TV stands and units UK living rooms are arranged around include heights from around 35cm upwards precisely because screen sizes have grown while sofa heights have not.

The equipment behind the screen

A television unit is a cable management problem wearing a piece of furniture. Before choosing, count what has to live in it: a set top box, a games console, a router, a sound system, a streaming stick and the power supplies for all of them. Then check three things on the unit. First, the aperture size and position for cables, since a small hole at one end will not accept a plug. Second, the ventilation, because consoles and receivers generate heat and a sealed cabinet shortens their life. Third, whether the doors block the infrared sensors of anything inside them, which glass and mesh fronts avoid and solid doors do not.

Soundbars need their own allowance. Most require 8cm to 12cm of clear height, and they must sit below the bottom edge of the screen without intruding into the picture or covering the television’s own remote sensor. Where the shelf is fixed, measure it before buying the soundbar rather than after. Units with a deeper top surface, such as those in entertainment units UK media rooms are built around, generally handle multi component setups better than slim consoles designed for a single screen.

Three households, three sets of requirements

In rented flats and first homes, the television unit is chosen with drilling ruled out. Wall mounting is rarely permitted, so the furniture has to carry the screen, and it usually has to carry a console and a router too. Low, wide and light is the pattern that works, along with open shelving that keeps equipment ventilated and accessible. A design that can be moved by one person matters more than it does in any other household, since the next room may be a different shape entirely.

Family households are storing far more than electronics. Games, controllers, cables and the accumulated contents of a living room all end up in the television unit, which makes closed storage the deciding feature. Stability is the other consideration: any unit that a child could climb should be secured to the wall with a restraint, and top heavy arrangements should be avoided entirely. Solid, low slung designs from a range of wooden TV stands UK family rooms use tend to be the steadiest option, since weight and a low centre of gravity work in your favour.

In long settled homes the priorities shift towards visibility and tidiness. A screen viewed from an armchair rather than a low sofa sits higher relative to the eye, so the unit can be taller. Cable clutter is a persistent irritation, so cabinets with concealed routing and closed backs are valued, as is a surface that wipes clean and reflects light in a room used mostly in the evening. That combination explains the continued appeal of high gloss TV stands UK sitting rooms are furnished with, though gloss finishes do show dust and fingerprints under lamplight.

Rooms that do not offer a straight wall

A great many British living rooms have a chimney breast, a bay window and a door in the remaining wall, which leaves no clean run for a large screen. Two solutions work. The first is an alcove arrangement, placing a lower unit in one alcove and treating the chimney breast as the backdrop. The second is a corner position, which uses the diagonal of the room and often produces a better viewing angle for a sofa set at an angle to the fireplace. Options among corner TV stands UK period homes rely on are built for exactly that geometry, with an angled back that sits flush across the corner.

Whichever is chosen, check the socket position first. A television placed where there is no socket produces either a trailing cable across a walkway or an unplanned electrical job, and both are avoidable with five minutes of measuring.

What this means for UK homes

Convert the screen diagonal into a width, add at least 20cm and treat that as the minimum unit size. Measure your seated eye level, subtract half the picture height and you have the maximum sensible height for the top of the unit. Those two figures narrow the choice faster than any style consideration.

Then plan the equipment. Count the boxes, check the cable apertures, confirm the ventilation and measure the soundbar shelf. In homes with children, fit a wall restraint and keep the heaviest items low. In rented homes, assume the screen sits on furniture rather than the wall. Get those decisions right and the unit will outlast at least two televisions, which is more than most living room furniture can claim.

Methodology

This 2026 report is based on the editorial assessment of Furniture in Fashion as a UK modern furniture retailer, together with standard furniture dimensions, the fixed geometry of 16:9 screen formats and named UK product safety standards where they apply to domestic storage furniture. Screen widths and picture heights are calculated from the standard 16:9 aspect ratio and rounded. No proprietary sales data, search data or customer records were used, and no survey fieldwork was carried out.

Frequently asked questions

How wide should a TV unit be for a 55 inch television?

At least 140cm. A 55 inch screen in 16:9 format measures around 122cm across, and a unit should extend beyond the screen by at least 20cm in total. Wider still looks more settled in the room.

How high should a TV unit be?

Usually 40cm to 55cm for a room where people watch from a sofa. Measure your seated eye level, which is commonly 100cm to 120cm, and aim to keep the centre of the screen at or slightly below it.

Is it a mistake to put a television above a fireplace?

It is a compromise. A mantel pushes the screen well above seated eye level, which means tilting the neck back throughout a film. Where the chimney breast is the only option, a lower unit with the screen mounted just above it is more comfortable than a full height installation.

How much space does a soundbar need?

Between 8cm and 12cm of clear shelf height for most models. Check that it does not cover the bottom edge of the screen or block the television’s remote sensor, and measure the shelf before choosing the soundbar.

Should a TV unit be secured to the wall?

Any unit that is tall, top heavy or reachable by a young child should be fitted with an anti tip restraint. Domestic storage furniture in the UK is covered by BS EN 14749, and a wall fixing is a sensible precaution regardless of the design.
