Grey TV Unit Measurements Made Simple: Will It Fit Your Room?

To check whether a grey TV unit will fit your room, you need four measurements: the width of the wall space, the depth available before walkways or doors, the width of your TV including its stand, and the seated eye height from your sofa. As a general guide, choose a unit wider than the TV, shallow enough to leave a clear walkway of roughly 80cm or more in front of it, and low enough that the centre of the screen sits close to seated eye level.

That is the quick version. Below, we break each measurement down so you can buy with confidence. Grey is a forgiving colour that suits almost any scheme, and our range of modern TV units UK includes light, mid and charcoal grey designs in a wide spread of sizes. Getting the numbers right first makes choosing between them far easier.

What You Need Before You Start

A metal tape measure, a notepad and ideally a second pair of hands. Painter’s masking tape is also useful for marking the unit’s footprint on the floor and wall, so you can see how it will look before it arrives. Measure everything in centimetres, since that is how most furniture dimensions are listed.

It also helps to note the sizes of the other pieces in the room, such as the sofa, coffee table and any sideboard. A TV unit never sits in isolation, and checking it against the rest of your living room furniture UK sale keeps the proportions balanced. A unit that suits the wall but dwarfs a compact sofa, or disappears beside a large corner sofa, will never feel quite right.

Measurement One: Wall Width

Measure the full width of the wall where the unit will go. Then note anything that limits the usable space: radiators, sockets, doors, windows and skirting boards that step out. In period homes, alcoves beside a chimney breast are often narrower than they look, and rarely truly square, so measure at the back, middle and front of the alcove and use the smallest figure.

As a rule of thumb, leave some breathing space either side of the unit. A unit that fills a wall edge to edge can look built in, which works in an alcove, but on an open wall a small gap either side usually looks more balanced.

Measurement Two: TV Width

TV sizes are measured diagonally, which is not much use when you are fitting furniture. What matters is the physical width of the screen. Check the specifications for your model, but as a rough guide for standard widescreen TVs:

• A 43 inch TV is roughly 96cm wide.
• A 50 inch TV is roughly 112cm wide.
• A 55 inch TV is roughly 123cm wide.
• A 65 inch TV is roughly 145cm wide.
• A 75 inch TV is roughly 167cm wide.

Frames and bezels add a little to these figures. If the TV will stand on the unit, also measure the width and depth of its feet or pedestal. Some TVs have feet at the far edges, which means the unit must be at least as wide as the screen. Others have a central stand, which gives more flexibility.

For a balanced look, choose a unit noticeably wider than the TV. A screen that overhangs the unit looks precarious and unfinished. If you want the arrangement to look settled, aim for the unit to extend a little beyond the screen on each side.

Measurement Three: Depth and Walkways

Depth is the measurement people most often forget. Measure from the wall to where the unit’s front would sit, and then check how much space remains in front of it. You need enough room to walk past comfortably, open any doors or drawers on the unit and move around the coffee table.

In most homes, a clear walkway of around 80cm to 90cm feels comfortable. In a narrow terrace lounge, a slimmer unit may be the difference between a room that flows and one where you turn sideways to get past. Also check whether a door into the room will swing into the unit’s path.

Remember to allow a few centimetres behind the unit for cables and plugs, unless it has a recessed back. Skirting boards can also push a unit forward slightly.

Measurement Four: Height and Eye Level

Sit on your sofa in your normal viewing position and have someone measure from the floor to your eye level. For most sofas, this lands somewhere around 100cm to 110cm. The centre of the TV screen should sit close to that height.

To work out the ideal unit height, subtract half the screen’s height and the height of the TV’s stand from your eye level. For many setups, that points to a unit somewhere between 40cm and 55cm tall. Low line units fit this range well. If you prefer a taller unit for storage, consider mounting the TV on the wall at the right height instead, with the unit below it.

Viewing Distance

How far you sit from the screen affects comfort as much as height. A common rule of thumb is to sit roughly one and a half to two and a half times the screen’s diagonal size away. For a 55 inch screen, that suggests a distance of around two to three and a half metres. Modern high resolution screens allow you to sit a little closer without seeing pixels, so use this as a guide rather than a strict rule.

In smaller rooms, a more modest screen on a well sized unit often feels more comfortable than a very large screen at close range.

Corners and Awkward Walls

If the only available space is a corner, measure along both walls from the corner point and note the diagonal distance across. A dedicated corner unit is shaped to fit this space, and our corner TV stands UK are designed for rooms where doors and windows leave no straight wall free. Measure the TV’s width carefully, since corner units usually have a narrower front edge than straight ones.

For sloping ceilings, bay windows or walls with a radiator, sketch the wall on paper with each obstacle marked. It is much easier to spot problems on a simple drawing than by eye.

Wall Mounting Changes the Maths

If you mount your TV on the wall, the unit no longer needs to support the screen, which frees you to choose based on storage and proportion alone. A wall mounted TV above a low unit keeps the floor clear and gives more flexibility on width. You still want the unit to look proportionate beneath the screen, so a unit at least as wide as the TV usually looks best. A sturdy bracket from our wall TV brackets UK sale range lets you set the screen at exactly the right height.

Choosing the Right Shade of Grey

Once the dimensions are clear, the shade matters. Light greys make a unit look smaller and suit compact rooms. Mid greys are versatile and hide everyday marks well. Charcoal adds weight and definition, which can anchor a large room but may feel heavy in a small one.

Consider the undertone too. Cool blue greys suit bright, south facing rooms. Warm greys with a hint of beige feel softer in north facing rooms and sit comfortably with oak floors. Hold a sample or swatch against your wall in daylight before you decide.

Test It Before It Arrives

Use masking tape to mark the unit’s width and depth on the floor, and its height on the wall. Leave it in place for a day or two and walk around it. You will quickly notice if it feels cramped, if a door clips it or if it looks too small for the wall. It is a simple step that prevents most sizing mistakes.

Also check the route into the room. Measure doorways, hallways and stair turns, especially in flats and older houses with narrow staircases. Most units arrive flat packed or in manageable sections, but it is worth confirming the largest box size.

Bringing It Together

Measuring for a TV unit comes down to four numbers: wall width, TV width, available depth and seated eye height. Once you have those, choosing a grey unit that fits becomes straightforward. If you are also thinking about where the unit should sit in relation to windows and light, our guide to TV unit placement in UK living rooms covers that in detail.

Frequently Asked Questions

How much wider should a TV unit be than the TV?

Aim for a unit noticeably wider than the screen, so it extends a little beyond each side. This looks balanced and gives the TV a stable base.

What height TV unit do I need?

For many setups, a unit between 40cm and 55cm tall places the screen centre near seated eye level. Measure your own eye height from the sofa to be sure.

How deep should a TV unit be?

Deep enough for your TV stand and devices, while leaving a comfortable walkway of around 80cm or more in front. Slimmer units suit narrow rooms.

Which shade of grey suits a small living room?

Light and warm greys tend to make a unit feel smaller and brighter, helping a compact room feel more open.
