A 55 inch television is measured across the diagonal of the screen, not its width, which catches many people out. In practice a typical 55 inch set is around 123 centimetres wide, give or take depending on the bezel. That width is the figure that matters most when choosing a unit, since the base needs to support and visually balance the screen rather than match its diagonal.
Knowing the real width helps you avoid the common mistake of buying a unit that looks fine in a showroom but appears undersized once the television sits on it at home. Always work from the actual measurements of your set rather than the headline screen size.
The widely used guide is that a television unit should be wider than the screen itself. For a 55 inch set, that means looking for a unit of roughly 130 centimetres or more. This keeps the screen from overhanging and gives a sense of stability, with the unit clearly carrying the television rather than straining beneath it.
A little extra width on each side also leaves room for a lamp, a plant or a few styled pieces, which softens the hard rectangle of the screen. If you prefer a bolder, more minimal look, a unit much wider than the set creates a calm, gallery like effect. Browsing our TV units range with that 130 centimetre figure in mind narrows the choice quickly.
Height is just as important as width. For comfortable viewing, the centre of the screen should sit roughly at eye level when you are seated on your usual sofa. Sit too low and you find yourself looking down, sit too high and your neck tires over a long film.
Most sofas place a seated eye level fairly low, which is why low, long units suit so many UK living rooms. If your television stands on the unit rather than being wall mounted, factor in the height of its own stand when judging the total. Our broader living room furniture range includes a spread of heights to suit different seating.
Depth keeps a 55 inch television safe. The unit top should be deep enough that the feet or central stand of the set rest fully on the surface, with no part of the base overhanging the front edge. Many modern televisions have widely spaced feet, so check the distance between them and confirm the unit can take that span.
If your set uses two feet rather than a central pedestal, the unit width becomes even more important, since the feet often sit close to the outer edges of the screen. A unit that is too narrow may leave the feet hanging off the ends, which is both unsafe and unsightly.
If you plan to wall mount the screen, the unit no longer needs to support its weight, which frees you to choose based on storage and proportion instead. Even so, the width guide still applies for looks, since a unit narrower than the screen above it can appear unbalanced. A unit a little wider than the mounted television keeps the wall composition settled.
With wall mounting, you can also opt for a lower unit purely for storage and styling, leaving a gap between it and the screen. This look suits modern rooms and gives flexibility with cable routing. The designs in our TV stands units and cabinets range cover both freestanding and wall mounted setups.
A unit does not exist in isolation, so consider the wall and the room. Leave space either side so the unit does not crowd a doorway or radiator, and check that drawers and doors can open fully without obstruction. In a smaller room, a unit that is too long can dominate, so balance the width guide against the scale of the space.
Viewing distance matters too. A 55 inch screen is generally comfortable from around two to three metres away in a typical UK living room. If your seating is closer than that, a slightly smaller screen or a lower unit can ease the experience.
Put simply, aim for a unit around 130 centimetres or wider, deep enough to hold the feet safely, and at a height that places the screen near seated eye level. Get those three figures right and a 55 inch television looks settled and balanced rather than perched or oversized.
Taking a few measurements before you shop saves time and avoids returns. At Furniture in Fashion we offer a wide range of modern furniture across the UK, with units in many widths and heights to suit a 55 inch screen and the room it lives in.
How wide should a unit be for a 55 inch TV?
Aim for around 130 centimetres or more, since a 55 inch set is roughly 123 centimetres wide and the unit should sit wider than the screen.
What height of unit suits a 55 inch TV?
Choose a height that places the centre of the screen near eye level when seated, which usually means a low, long unit in most living rooms.
Does the unit need to be deep?
Yes. It must be deep enough for the feet or central stand to rest fully on the surface without overhanging the front edge.
Does wall mounting change the size I need?
It removes the weight requirement, but a unit slightly wider than the mounted screen still looks more balanced beneath it.
