Living Room Sideboard — Dimensions, Solutions, Ideas

June 5, 2026

A living room sideboard or chest of drawers is a half-height storage cabinet with drawers or doors that serves as primary storage for everyday items and is often used as a TV unit or credenza. When planning the layout, DIY enthusiasts must measure the available space accurately and choose fittings that match the spatial requirements and their own assembly skills. A well-considered concept for a living room chest of drawers prevents the room from feeling cluttered and ensures walkways remain unobstructed.

Dimensions and Room Planning: Depth, Width and Proportions

The dimensions of cabinet furniture decisively determine its functionality in the room. In contrast to a solid living room wardrobe that often reaches up to the ceiling, half-height furniture lets the walls breathe. The critical parameters when planning are depth and width.

Selecting the Right Depth

The depth determines how far the unit projects into the room.

Narrow floor plans: In tight rooms or along thoroughfares, models that are 30 cm deep or 35 cm deep are ideal. These dimensions provide enough space to store books, papers, or slim electronic devices without blocking the walkway.
Standard depth: A depth of 40 cm - 45 cm is considered standard. This easily accommodates folded textiles, ring binders, or larger household objects.

Adapting the Width to the Wall

The width must remain proportional to the available wall space.

Compact solutions: For alcoves or as a supplementary unit next to a sofa, a width of 70 cm - 75 cm is ideal.
Medium sizes: A 100 cm wide unit provides a balanced ratio of storage capacity to footprint, working harmoniously as a standalone piece.
Large formats: For long, bare walls or as a base for large TV sets, expansive models are required. Units starting from 200 cm are commonly used here. A sideboard 220 cm wide also structures large rooms effectively and offers generous storage space on a single horizontal line.

Material, Finish and Visual Room Impact

With flat-pack furniture, the carcass components typically consist of chipboard finished with a melamine resin coating. This surface is scratch-resistant and easy to maintain. Fronts are frequently made from MDF, as this material allows for finer routing and takes paint or foil finishes exceptionally well.

The choice of colour influences the perceived size of the room:

A white chest of drawers reflects daylight and makes the room appear visually larger and more open.
A black chest of drawers or anthracite models absorb light. They are ideal for creating bold contrasts in bright rooms or for visually integrating technology (such as televisions and speakers).
Wood finishes add natural texture to the interior. A classic oak chest of drawers looks warm, whilst darker wood finishes create a heavier, more traditional aesthetic.

Interior Layout: Drawers vs Doors

The choice of internal division depends on the items you intend to store. Drawers provide direct access from above to the entire contents, whilst compartments behind doors offer greater flexibility for bulky items.

Focus on drawers: When organising smaller items, a unit with multiple drawer runners is practical. A 4-drawer chest is the classic choice for documents and accessories. For finer organisation, an 8-drawer chest may be the better option.
Runner mechanisms: Drawer runners differ fundamentally. A full-extension runner pulls out 100% from the carcass, allowing convenient access even to the rearmost corner. A partial-extension runner reveals only around 75% of the drawer depth. Movement is usually guided via metal ball bearing runners, which handle heavy loads, or simple roller runners.

Self-Assembly: Tools and Process

Assembling cabinet furniture is like a three-dimensional puzzle, where the back panel provides essential angular rigidity. For smooth assembly, prepare your workspace and arrange the appropriate tools beforehand.

Required Tools

Cordless screwdriver with matching bits (usually PZ2 for cross-head screws)
Rubber mallet for knocking in wooden dowels
Spirit level for final alignment
Tape measure

Key Assembly Steps

Carcass joints: Modern flat-pack units use cam and pin connectors (eccentric fittings). A dowel pin is screwed into one panel and inserted into the matching piece. Tightening the round cam pulls the panels flush together without gaps.
Back panel fitting: The back panel is either slid into a routed groove or pinned on with nails. It must be fixed at a precise right angle, otherwise doors and drawers cannot be adjusted correctly later.
Runners and hinges: Fit the drawer runners and hinge mounting plates to the side panels before assembling the carcass. Working on a flat board is considerably more ergonomic.
Wall mounting: Cabinets with drawers shift their centre of gravity forward when multiple drawers are pulled out simultaneously. Securing the unit to the wall with appropriate wall plugs and screws is mandatory to prevent tipping.

FAQ – Frequently Asked Questions About Living Room Sideboards

How do I align misaligned drawers after assembly?

The fronts of high-quality drawer systems can be adjusted. Undermount drawer runners often feature small adjustment thumbwheels underneath the drawer base, allowing height corrections of approximately 2 mm to 3 mm. For side-mounted runners, you may need to loosen the front fixing screws slightly, align the panel, and retighten the screws.

How do I adjust cabinet doors correctly?

If the furniture features doors, they are mounted to the carcass using concealed cup hinges. These hinges provide 3-way adjustment. The front screw on the hinge arm adjusts the lateral overlay (gap alignment). The rear screw regulates depth (the distance from the door to the carcass), and the screws on the mounting plate allow height adjustments.

What dimensions are required for placing a TV on a sideboard?

When using the unit as a TV stand, the carcass width should exceed the width of the TV screen by at least 10 cm to 20 cm to look visually balanced. The depth should be at least 35 cm to ensure the TV stand base rests securely.
