For most combined living and dining rooms, the right TV unit is noticeably wider than the television, low enough that the centre of the screen sits close to eye level from the sofa, and no deeper than roughly 40 to 45 centimetres so it does not eat into the walkway. In practice, many rooms suit a unit somewhere between two thirds and three quarters of the width of the TV wall, provided that leaves clear space for doors, radiators and circulation.
Our range of modern TV units UK homes choose for shared spaces includes compact low cabinets and longer, slimmer designs that suit a room where every centimetre has to work. The sections below explain how to measure and decide.
In a dedicated lounge, a TV unit only needs to relate to the sofa and the screen. In a living dining room, it is also seen from the dining table, the kitchen doorway and often the hallway. A unit that is too large can make the lounge end feel heavy and crowd the dining area. One that is too small looks lost, especially against a long wall.
Shared rooms also have more movement. People carry plates, pull out chairs and walk between zones. Any furniture that intrudes on these routes becomes an irritation very quickly. Getting the unit’s size right is therefore as much about comfort as appearance. If you are planning several pieces at once, viewing our modern living room furniture UK collection together helps you judge how the unit will sit with sofas and occasional tables of a similar scale.
Measure the full length of the wall, then subtract anything that interrupts it: radiators, door swings, windows, sockets you need to reach and skirting heaters. In many UK through lounges, the TV wall is the chimney breast, so measure the breast and each alcove separately.
Measure the physical width of the screen, not its diagonal size. If it stands on feet, note how far apart they are, because some televisions place feet near the edges and need a wider top surface.
Measure the distance between the TV wall and the front of the sofa, and between the back of the sofa or armchairs and the dining table. A comfortable walkway is usually around 80 to 90 centimetres. Behind dining chairs, allow enough room to pull a chair out and sit down without bumping into anything.
Sit on the sofa and look at the wall. Then sit at the dining table and do the same. Note whether you want to see the screen from the table, since this affects where the unit should go and how high the screen needs to be.
A reliable starting point is a unit that extends beyond the television by at least a hand span on each side. This keeps the arrangement stable and balanced, and gives space for a lamp or a small group of objects.
From there, consider the wall. On a long wall, a longer unit creates a strong horizontal line that visually anchors the lounge zone. On a short wall or chimney breast, a unit that fills the breast neatly, or sits within one alcove, often looks more considered than one that sprawls.
In open plan rooms, avoid running the TV unit the full length of a wall that continues into the dining area. Stopping the unit at the edge of the lounge zone helps define where one area ends and the next begins.
The centre of the screen should sit close to eye level when you are seated on the sofa. For most people and most sofas, this points towards a fairly low unit, particularly with larger televisions placed on top.
In a living dining room, there is a second consideration: whether the screen needs to be visible from the table. Dining chairs place your eyes higher than a sofa, so a screen at sofa height may still be visible from the table, but viewing angles will be less comfortable. For most households, prioritising the sofa is sensible, since longer viewing happens there.
Low units also help in shared rooms by keeping the space feeling open. A tall cabinet at the lounge end can block light and views across the room.
Depth is the dimension most often overlooked. A deep unit can narrow the walkway in front of the sofa, particularly in the compact reception rooms common in UK homes. Many modern TV units are designed to be relatively shallow while still accommodating equipment.
Before buying, check that the unit’s depth leaves a clear route and that doors or drawers can open fully without hitting the coffee table. If the TV is wall mounted, you can often choose an even shallower unit, since it no longer has to support the screen.
The size of the television influences everything else. A common rule of thumb is to sit at a distance of roughly one and a half to two and a half times the screen’s diagonal size. In a smaller living dining room, where the sofa sits close to the TV wall, a very large screen can feel overwhelming and require a unit that dominates the lounge zone.
If you are replacing both screen and unit, it can be worth choosing a slightly smaller television and a better proportioned unit, which often gives a more comfortable room overall.
In many layouts, the sofa backs onto the dining zone, facing a TV unit on the far wall. This is the simplest arrangement and uses the sofa as a natural divider. The unit then only needs to suit the lounge.
Where the TV wall runs along the side of an open plan room, the unit is visible from both zones. Here, a long, low unit with closed storage keeps the view tidy from the table.
In some rooms, a low unit or shelving can sit between the zones, creating separation without closing off the space. Our range of room dividers UK homes use can also help separate living and dining areas while keeping light flowing.
A living dining room often has to hold more than media. Board games, placemats, homework, chargers and post all tend to gather there. A TV unit with a mix of drawers and closed cabinets can absorb some of this, easing pressure on the dining area.
Think about what you need to store near the table. If you have a sideboard in the dining zone, the TV unit can focus on media and games. If not, choosing a unit with extra closed storage may be the more practical option.
The TV unit and the dining table should feel like they belong in the same room. Repeating a wood tone or finish between the two helps. So does keeping their scale in proportion: a very long TV unit alongside a small bistro table can feel lopsided.
If the dining area needs to flex for guests, an extending table keeps everyday space free. Our modern extending dining tables UK sale collection offers designs that sit comfortably alongside a lounge area day to day and open up when needed.
Victorian or Edwardian through lounge. The front half is often the living area with a chimney breast, and the rear half the dining area. A low unit centred on the front chimney breast, with the TV above or on top, respects the architecture. Keep the rear chimney breast for a sideboard or display.
New build open plan. Rooms are often long and rectangular. Place the TV unit on the shorter end wall at the lounge side, or along the long wall with the sofa backing onto the dining table.
Compact flat. Every centimetre counts. A wall mounted screen with a slim floating unit keeps the floor clear, and a round dining table makes circulation easier.
If you are still exploring the different types of media furniture, our guide to buying an entertainment unit for a UK home explains storage and features in more depth. For advice on colour and finish, our piece on grey TV units for UK living spaces looks at a shade that bridges living and dining zones well.
Mark the unit’s footprint on the floor with masking tape and live with it for a day or two. Walk around it, pull out the dining chairs and sit on the sofa. This quick test reveals far more than measurements alone. When you are ready, you can explore our full range of modern furniture at Furniture in Fashion.
Wider than the television with a comfortable margin either side, and usually no more than the length of the lounge zone’s wall so it does not spill into the dining area.
A shallow unit keeps walkways clear. Check that doors and drawers can open fully without hitting the coffee table.
It is a personal choice. Most households prioritise viewing from the sofa, where longer viewing happens, and accept a less direct angle from the table.
A low, finished back unit can help separate zones, though you will need to plan cable routes carefully if the screen sits on it.
