What Size Display Cabinet Do You Need for an Open Plan Space?

In an open plan space, size your display cabinet to the zone it serves rather than the whole room. As a working guide, choose a width of roughly half to two thirds of the wall section it stands against, a height that lines up with nearby furniture or kitchen wall units, and a depth that leaves a clear walkway of around 90 centimetres in front. A cabinet sized this way looks deliberate rather than lost or oversized.

Open plan rooms can be deceptive. The overall floor area is large, so it is tempting to buy big, yet each part of the room has its own job and its own limits. Our modern display cabinets UK sale collection covers everything from compact single door units to wide double door pieces, so you can match the cabinet to the space it will actually occupy.

Measure the Zone, Not the Room

An open plan kitchen, dining and living area is really three rooms without walls. Before thinking about cabinet size, decide which zone the cabinet belongs to. A cabinet in the dining area relates to the table and chairs. A cabinet in the lounge relates to the sofa and media wall. A cabinet on the boundary between zones has to work from both sides.

Once you know the zone, measure three things:

• The length of the wall, or wall section, the cabinet will stand against.
• The distance from that wall to the nearest piece of furniture or kitchen island.
• The height of the tallest neighbouring item, such as kitchen wall cupboards, a tall fridge, a bookcase or a window head.

These measurements will guide width, depth and height respectively.

Choosing the Right Width

Width is what gives a cabinet presence. Too narrow and it reads as an afterthought against a broad wall. Too wide and it dominates the zone.

A cabinet occupying around half to two thirds of its wall section usually looks balanced. On a three metre stretch, that suggests something between about one and a half and two metres wide, either as a single wide cabinet or a pair of narrower ones. On a shorter wall beside a doorway, a single door cabinet may be all you need.

Think about what sits either side. A lamp, a plant or simply some clear wall gives the cabinet room to breathe. In open plan spaces, that breathing room is part of what keeps the area feeling calm.

Choosing the Right Height

Height is where open plan rooms differ most from separate rooms. Your display cabinet will be seen alongside kitchen units, dining furniture and seating all at once, so it helps to align it with something.

• Low cabinets at sideboard height line up with kitchen worktops and dining tables. They keep sightlines open across the room and suit spaces where you want to see from the kitchen to the garden.
• Medium height cabinets, reaching roughly shoulder height, sit comfortably beside sofas and create a little enclosure for the lounge without blocking views.
• Tall cabinets work best when they align with kitchen wall units, door heads or tall appliances. Matching these lines makes the cabinet feel part of the architecture.

If your open plan room has a high or sloping ceiling, a tall cabinet can look graceful. With a standard ceiling, a medium height cabinet often feels more relaxed.

Considering the cabinet alongside your other furniture helps here. Our living room furniture UK range includes coordinating pieces at different heights, which makes it easier to plan a consistent line across the space.

Depth and Clearance

Depth affects movement. Display cabinets are often shallower than sideboards, typically somewhere around 35 to 45 centimetres, because they hold objects rather than bulky storage. In an open plan room, that shallow depth is valuable.

Keep a clear walkway in front of the cabinet. Around 90 centimetres is a comfortable width for one person to pass, with more needed where people cross paths, such as between a kitchen island and a dining area. If the cabinet has hinged doors, add the door swing to the depth when checking clearance.

Check skirting boards and radiators too. A deep skirting or a radiator valve can push a cabinet forward by a few centimetres, which matters when space is tight.

A Simple Sizing Reference

Treat this as a starting point rather than a rule. Your room’s proportions, light and furniture will refine it.

Using a Cabinet to Divide Zones

A display cabinet placed at right angles to a wall, or floating between zones, can define an area without building a wall. For this job, size matters in a different way.

Low and medium height cabinets work best as dividers because they mark a boundary while keeping the room open. A tall cabinet in the middle of a room can feel like a barrier and may block light from the windows. Choose a design that is finished on the back, ideally with glass on both sides, so it looks good from either zone.

For a lighter boundary, a screen or open partition can work alongside or instead of a cabinet. Our room dividers UK collection offers options that define space while letting light through.

Relating the Cabinet to Your Dining Furniture

In many open plan homes, the display cabinet sits near the dining table, often holding glassware and serving pieces. Here, the cabinet should feel related to the table in scale. A long dining table for six or eight suits a wider cabinet or a low run of storage. A compact round table suits a single, taller cabinet that does not overwhelm it.

If you need closed storage for table linen and plates as well as display space, a dining sideboard can work alongside the cabinet. Our dining room sideboards UK sale range includes low pieces that pair well with a taller glazed cabinet on the same wall.

Testing the Size Before You Buy

A tape measure tells you if something fits. It does not always tell you how it will feel. Two simple tests help:

1. Mark the footprint. Use masking tape on the floor to outline the cabinet’s width and depth. Walk around it for a day or two and see whether it interrupts natural routes.
2. Mark the height. Tape a line on the wall at the cabinet’s height, or prop up a large piece of cardboard. View it from the kitchen, the sofa and the doorway.

These quick checks often reveal whether a slightly smaller or larger cabinet would sit better. For detailed guidance on standard heights, depths and shelf spacing, see our article on display cabinet dimensions for UK homes.

One Large Cabinet or Two Smaller Ones?

Two matching cabinets give flexibility. They can sit side by side as one display, flank a window or fireplace, or be separated later if you rearrange the room. A single large cabinet makes a stronger statement and has fewer frame lines interrupting the display.

In open plan rooms that you may reconfigure over time, a pair is often the more adaptable choice. Where you have one clear feature wall, a single generous cabinet can look more confident.

Consider the view from the kitchen too. Open plan living means you will often see the cabinet while cooking or washing up, so its back, sides and top should look tidy from that angle as well as from the sofa. A cabinet with glass sides or a finished back panel suits this kind of room particularly well, and a few well spaced objects on the top keep the silhouette calm from across the space.

Final Thoughts on Sizing

In open plan living, the right display cabinet is the one that suits its zone. Measure the wall section and the walkway, align the height with something nearby and test the footprint before committing. The result is a cabinet that looks at home from every part of the room.

Frequently Asked Questions

How wide should a display cabinet be in an open plan room?

A useful starting point is half to two thirds of the wall section it stands against. This gives presence without crowding, and leaves room for a lamp or plant beside it.

Can a tall display cabinet work in an open plan kitchen diner?

Yes, especially when its height aligns with kitchen wall units or door heads. Place it against a wall rather than in the middle of the room, so it does not block light or views.

How much space should I leave in front of a display cabinet?

Around 90 centimetres is a comfortable walkway for one person. Allow more where routes cross, and add the swing of any hinged doors.

Is a low or tall cabinet better as a room divider?

Low and medium height cabinets usually work better. They define the zone while keeping sightlines and light flowing across the open space.
