80 cm Wide Chest of Drawers: Why This Standard Size Fits Almost Every Room

June 21, 2026

An 800 mm wide chest of drawers represents the ideal compromise in cabinet making between maximum storage volume and structural stability for standard furniture fittings.

Anyone planning or assembling a carcase quickly encounters the 800 mm grid size (often referred to as 80 cm). From an engineering perspective, this dimension is no accident. It is based on the load-bearing limits of engineered wood panels and the standardised load capacities of common hardware. An 800 mm wide cabinet acts in spatial planning much like a standard Euro-pallet space in logistics: it maximises usable area without overloading the supporting structure with leverage forces.

This guide explains the technical criteria that are crucial when selecting, planning, and assembling a chest of drawers in this standard dimension.

Key Buying and Construction Criteria

At a width of 800 mm, the requirements for the installed components increase considerably compared to narrower models. Physics demands precisely matched fittings here.

Statics and Deflection (Material Thickness)

A shelf or drawer bottom made of 16 mm thick chipboard tends to sag under load across a clear span of roughly 768 mm (800 mm minus twice the 16 mm carcase side panels). For storing heavy tools or crockery at this width, a material thickness of 19 mm or the use of stiffening profiles is essential. For normal clothing, standard thickness suffices, provided the back panel is grooved and screwed to give the carcase the necessary torsional rigidity.

Runner Systems and Load Capacity

Drawers with a width of almost 800 mm hold a substantial volume. Filled with paper or textiles, weights of 15 kg to 25 kg are quickly reached.

Roller runners: Unsuitable for this width due to low lateral stability and a typical load rating of only 10 kg to 15 kg. The drawer tends to jam when pulled from one side.
Ball bearing runners: Offer a load capacity of 30 kg to 45 kg as a full extension. The lateral telescopic mechanism reliably prevents jamming.
Undermount runners: The technically cleanest solution. The runner sits concealed beneath the drawer base. Integrated synchronisation shafts ensure that even 800 mm wide drawer fronts open and close perfectly parallel.

Hinge Technology for Hinged Doors

If the chest of drawers is fitted with doors, the 800 mm width is typically split into two 400 mm fronts. This is structurally an excellent dimension. A 400 mm wide door generates significantly less leverage on the hinges than wider fronts. A standard concealed hinge with a cup diameter of 35 mm and an opening angle of 110° is the norm here. If the doors sit fully over the front edge of the carcase side panels, a full overlay hinge is used.

The 32 mm System

Internal construction follows the 32 mm system. The vertical drilling holes for shelf supports or mounting plates are spaced exactly 32 mm apart. The drill hole diameter for shelf studs is usually 5 mm. This ensures that shelves can be repositioned flexibly and standard hardware fits without remeasuring.

Overview of Types and Options

The 800 mm grid size allows for various configurations, each placing specific demands on the hardware technology.

Drawer-only chests (apothecary style): Strictly require premium-quality runners. If handleless fronts are desired, a tip-on mechanism (push-to-open) is fitted. Note: a mechanical push-to-open system cannot be combined with standard soft-close damping, as both systems rely on opposing spring forces.
Door units with shelves: The classic construction. Here, cam and dowel connectors (Minifix) secure fixed structural panels, while adjustable shelves rest on shelf supports.
Combination units (drawers above, doors below): Requires precise hinge mounting plates so the lower door does not catch on the upper drawer front when opening. A reveal gap of 2.5 mm to 3 mm should be planned.

Which Configuration for Which Application?

The choice of the correct fittings and depth dimensions depends on the intended location. The 800 mm width is fixed, but depths and mechanisms vary.

For narrow hallways and entryways: Depth is the limiting factor here. A carcase with a depth of 300 mm or 350 mm requires short runners (e.g. 250 mm nominal length). As standard shoes are often deeper, flap fittings or angled internal shelves are installed. For extremely confined spaces, alternatives like a small chest of drawers or a 60 cm wide chest of drawers are often selected.
For the bedroom (clothing): Deep runners (450 mm to 500 mm) are essential for organising stacks of clothing lengthways. A bedroom chest of drawers with an 800 mm width provides space for exactly two stacks of jumpers side by side. If more hanging or storage space is needed, modular planning often places a 100 cm wide chest of drawers alongside it.
For heavy loads (office/workshop): For storing lever arch files or tools, the 800 mm dimension works well, but it must be fitted with ball bearing runners rated for 45 kg. If space is tight, a more compact 70 cm wide chest of drawers can be structurally advantageous because shelf deflection is reduced.
For large wall areas: A single 800 mm unit can look lost against a long wall. Often, two 800 mm carcases are joined together, or a 120 cm wide chest of drawers is chosen directly, where the structure is internally supported by centre partition panels.

Installation and Assembly Tips for DIYers

Assembling an 800 mm wide carcase correctly requires precision. Alignment errors at this width quickly result in jamming drawers or uneven gaps.

Required Tools

Cordless screwdriver with torque limiter
Bits: PZ (Pozidriv, usually PZ2 for fittings) and TX (Torx)
Spirit level (at least 600 mm long)
Folding rule and set square

Step-by-Step Assembly

Pre-fit the runners: It is technically much easier to mount the cabinet runner rails horizontally to the side panels before assembling the main carcase. Use the 32 mm system hole line and secure the rails with wood screws (typically 4 x 16 mm) or specialised Euro screws.
Join the carcase: Insert the wooden dowels and place the cam connectors into the pre-drilled holes. Tighten the cams clockwise using a screwdriver until you feel them lock securely into place (usually after a half turn).
Check squareness: Before fixing the back panel, ensure the carcase is completely square. Measure both diagonals across the back. If both dimensions are identical to the millimetre, the carcase is at a precise 90° angle.
Nail/screw the back panel: The back panel provides the 800 mm wide structure with shear resistance. Screws (e.g. 3 x 20 mm) offer significantly higher pull-out resistance than nails.
Align in position: An 800 mm wide carcase does not tolerate uneven floors. Use height-adjustable cabinet feet (often with an M8 thread in a threaded insert) to level the carcase perfectly horizontally. If the unit sits unevenly, the 800 mm wide drawers will twist and the soft-close mechanism will stick.

Frequently Asked Questions (FAQ)

Will an 800 mm wide shelf sag? That depends on the material and the load. A 16 mm thick shelf made of standard chipboard will visibly sag over this width under a continuous load exceeding 15 kg. For books or heavy crockery, a thickness of 19 mm should be selected or additional shelf studs should be installed at the back panel.

Which runners are best suited for 800 mm wide drawers? For this width, undermount runners or side-mounted ball bearing runners are strongly recommended. They provide the lateral stability needed to prevent binding or jamming during opening. Roller runners are technically unsuitable for this span.

Do 800 mm wide chests of drawers fit in narrow hallways? Yes, provided the depth is appropriately reduced. Standard depths range from 400 mm to 450 mm. For hallways, versions with a depth of 300 mm are available. Keep in mind that with such shallow depths, the nominal length of the runners must be at most 250 mm to 270 mm.

How many hinges does a 400 mm wide cabinet door require? For a standard height of up to 900 mm, two concealed hinges are completely adequate. Only from a door height above 900 mm or with heavier materials (such as solid MDF with a mirror) is a third hinge in the centre needed to absorb the leverage forces.

Can I combine push-to-open and soft-close? No, with purely mechanical systems this is physically impossible. The push-to-open mechanism requires a spring to push the drawer open, while the soft-close damper brakes the drawer and pulls it closed. Both forces work against each other.
