Choosing a sideboard often begins with its appearance. A beautifully finished cabinet may seem right for the room, but its dimensions determine whether it will provide enough storage and fit comfortably alongside the surrounding furniture.
If you are wondering what size sideboard you need, start with the available wall space, the depth of the room and what you intend to store. A compact two-door cabinet may be sufficient for a smaller living room, while a larger dining room could benefit from a four-door design with more internal storage.
Width is only part of the decision. Depth, height, door clearance and the arrangement of internal shelves can be equally important when choosing furniture that will remain practical for years.
Sideboard Size Guide: Common Widths and Dimensions
Sideboards are available in a wide range of proportions, from relatively compact storage cabinets to substantial designs intended for generous living and dining rooms. The following measurements provide a useful starting point rather than fixed furniture standards.
| Sideboard width | Typical application | What to consider |
|---|---|---|
| 80–110 cm | Smaller rooms, alcoves and compact storage areas | Useful where wall width is limited; check internal storage capacity |
| 120–150 cm | Medium-sized living rooms and dining areas | Provides a broader display surface without requiring an exceptionally long wall |
| 150–180 cm | Living rooms and dining rooms requiring more storage | Check the relationship between cabinet width, door openings and nearby furniture |
| 180–200 cm | Larger rooms and substantial storage arrangements | Offers a strong visual presence; needs appropriate wall space and circulation clearance |
| Over 200 cm | Generous interiors and extensive storage requirements | Consider delivery access, room proportions and the scale of surrounding furniture |
These ranges describe possible uses, not guaranteed suitability. A sideboard measuring 150 cm wide and 37 cm deep will occupy a different amount of floor space from one measuring the same width but 50 cm deep.

How Wide Should a Sideboard Be?
Begin by measuring the wall where the sideboard will stand. Note the position of doors, radiators, sockets, skirting boards and any furniture that needs to remain accessible.
A sideboard does not need to fill the entire wall. Leaving visible space at either end often creates a more comfortable arrangement and allows the cabinet's shape to remain distinct.
In a smaller room, a cabinet around 90–120 cm wide may provide enough concealed storage without dominating the wall. In a larger interior, a 160–200 cm sideboard can establish a more substantial focal point, particularly beneath a large mirror or artwork.
The width should also reflect what you intend to store. A two-door cabinet may accommodate occasional tableware, books or accessories, while a four-door design can provide more flexibility for larger collections.
What Size Sideboard Works in a Small Living Room?
In a smaller living room, depth may be more important than width. A cabinet that extends too far into the room can restrict access to a sofa, armchair or doorway even when it fits neatly against the wall.
For example, the Ashbourne Small Dark Oak Sideboard measures 93 cm wide, 45 cm deep and 88 cm high. Its two-door construction offers concealed storage, while the dark oak finish and slender iron legs give the relatively compact cabinet a defined silhouette.
The 93 cm width makes it worth considering for a shorter wall or an area where a full-sized four-door sideboard would be excessive. However, its 45 cm depth must still be included when calculating the remaining floor space.
Raised legs can make a cabinet appear visually lighter, but they do not reduce its actual footprint. Always assess the room using the complete product dimensions.
How Deep Should a Sideboard Be?
Many sideboards measure approximately 35–50 cm deep, although individual designs vary. The correct depth depends on the available floor space and the objects you need to store.
A shallower cabinet can be useful along a circulation route or in a room where other furniture already occupies considerable space. However, it may offer less capacity for large serving dishes, storage boxes or bulky household items.
Deeper cabinets can accommodate more substantial belongings, but they need careful positioning. Measure the distance between the sideboard and the nearest table, chair or other obstacle.
Also consider how the doors open. A cabinet that fits neatly against the wall can still be inconvenient if its doors cannot open fully because of nearby furniture.
The Sunburst Four-Door Sideboard illustrates why width and depth should be considered separately. At 157 cm wide, 37 cm deep and 92 cm high, it offers a broad cabinet with a relatively shallow profile. Behind its brass-toned radial fronts are two storage sections with adjustable shelving.
Its proportions may suit a dining room or generous hallway where considerable wall width is available but floor depth needs to be managed carefully. The four doors still require sufficient space to open comfortably.
What Is the Best Height for a Sideboard?
Sideboard height influences both accessibility and the relationship between the cabinet and the surrounding room. Many contemporary designs stand approximately 75–95 cm high, though some are lower or taller.
In a dining room, the top may be used for serving dishes, arranging glasses or displaying lighting. Consider whether the height is comfortable for these activities and whether the surface needs to remain partly clear.
In a living room, a taller cabinet may sit comfortably beneath a substantial mirror or artwork, while a lower design can create a more horizontal composition.
Pay attention to the overall height rather than the body of the cabinet alone. Raised legs, decorative bases and thick tops can substantially change how the furniture relates to nearby pieces.
What Size Sideboard Do You Need for a Dining Room?
A dining room sideboard should be selected according to both storage requirements and the available space around the dining table.
Start by considering the contents. Dinner plates, serving bowls, glassware and table linen have different storage needs. Check the internal shelf dimensions and whether shelves are adjustable rather than assuming a larger exterior always provides a more useful interior.
A sideboard around 140–180 cm wide may offer sufficient storage for many dining arrangements, depending on its construction. Larger households or frequent hosts may benefit from a broader cabinet, but additional width is useful only when the furniture fits the room comfortably.
The position of the dining chairs is particularly important. When chairs are pulled away from the table, there should still be room to walk past and access the sideboard.
If the cabinet will also function as a serving surface, allow enough clear space on top for the items used during meals. A decorative arrangement that occupies the entire surface may look attractive but make the cabinet less practical.
How Much Space Should You Leave Around a Sideboard?
Measure the room with the sideboard doors open, not only when the cabinet is closed.
The required clearance depends on the door dimensions, nearby furniture and whether the space forms part of a regular walkway.
As a general room-planning reference, approximately 90 cm of clear passage can be a useful starting point in areas where people need to move comfortably. More space may be necessary where cabinet doors open into the route or where people regularly pass behind occupied dining chairs.
These are planning considerations rather than universal rules. The final arrangement must also account for accessibility, door swings and the particular layout of the room.
Before ordering, mark the proposed cabinet footprint on the floor with masking tape. Open nearby doors, pull out dining chairs and walk through the space as you normally would.
For larger cabinets, also check the delivery route. Doorways, staircases, lifts and narrow turns can limit access even when the furniture will fit comfortably in its intended position.
Should You Choose a Sideboard or a Console Table?
A sideboard is usually the more practical choice when concealed storage is a priority. Its enclosed compartments can accommodate tableware, books, textiles or other belongings that do not need to remain visible.
A console table generally has a shallower profile and may offer little or no enclosed storage. It can be suitable for a narrow entrance, an area behind a sofa or a space intended primarily for lighting and decorative objects.
If your room has limited floor depth and substantial storage is not essential, explore our collection of console tables as an alternative.
If the main requirement is to organise everyday belongings behind doors or within drawers, a sideboard will often be the more useful starting point.
How to Make the Most of Your Sideboard
Once you have chosen the correct dimensions, consider how the sideboard will relate to the rest of the room.
A broad cabinet can be positioned beneath a mirror or artwork that corresponds to its proportions. A table lamp at one end may provide height, while a sculpture, vase or decorative bowl can introduce a different material or shape.
Cabinets with distinctive fluted, carved or metal-fronted doors may need fewer objects on top, allowing the construction and finish to remain visible.

Choosing the Right Sideboard for Your Home
Begin with the wall width and available floor depth, then consider the storage required. A compact cabinet may suit a smaller living room, while a wider sideboard with adjustable shelving can be more appropriate for a dining room containing larger quantities of tableware.
Check the complete exterior dimensions, internal storage arrangement and clearance needed for doors or drawers. Consider delivery access before selecting a particularly large piece.
Materials and finishes should be assessed in relation to the surrounding furniture. Dark oak can provide a strong visual anchor, while lighter timber, raised metal bases or contrasting decorative fronts can change how substantial a cabinet appears.

Frequently Asked Questions
What is a standard sideboard size?
There is no single standard. Many sideboards measure approximately 120–200 cm wide, but compact models can be narrower and statement designs considerably longer. Always check width, depth and height together.
Is a 150 cm sideboard big enough for a dining room?
A 150 cm sideboard can provide useful storage in many dining rooms. Its suitability depends on the internal shelving, the items you need to store and the space available around the dining table.
Can a sideboard be used in a hallway?
Yes, provided there is enough wall space and circulation clearance. A relatively shallow cabinet may work in a generous hallway, but the doors must remain fully accessible.
How much space should be left in front of a sideboard?
Allow sufficient room for the cabinet doors to open and for people to move comfortably. Around 90 cm of clear passage can be a useful planning reference, but the appropriate space depends on the room and furniture arrangement.
