Tallboy Chest of Drawers: Space-Saving Vertical Storage (Dimension & Hardware Guide)

March 19, 2026

A tallboy is a vertically orientated cabinet carcass whose height significantly exceeds its base width, offering maximum storage capacity on a minimal footprint by using stacked drawers or shelves.

When planning, assembling, or modifying such a piece of furniture, specific structural and mechanical requirements apply. Because the centre of gravity is located high up, tilt protection, correct fitting technology, and precise dimensions become the primary focus. This guide is aimed at fitters and DIY enthusiasts who want to technically evaluate, correctly assemble, or upgrade a tall chest of drawers with new components.

Key Buying and Construction Criteria

1. Dimensions and Usable Depth

The external dimensions dictate the internal hardware that can be fitted. For carcasses made of chipboard or MDF (usually 16 mm or 18 mm material thickness), the usable internal depth must be calculated precisely. A cabinet with an external depth of 300 mm, minus the front (approx. 16 mm) and the grooved back panel (approx. 15 mm recess), provides a clear internal depth of just under 270 mm. Here, drawer runners with a nominal length of 250 mm can be installed at most. With an external depth of 350 mm, runners with a length of 300 mm are compatible. The width influences deflection. For carcass widths of 700 mm to 1000 mm, drawer bottoms must be reinforced (e.g. 16 mm instead of 3 mm HDF board), or heavy-duty runners with a load capacity of 30 kg to 45 kg should be used.

2. Drawer Runner Systems and Extension Types

A tallboy often consists of drawers arranged one above the other. The choice of runners is decisive for accessibility:

Partial extension: The drawer extends to approximately 75%. The rear area remains inside the carcass. This is inconvenient in deeper constructions, but is often standard for very shallow depths (300 mm).
Full extension: The drawer extends 100% past the front edge of the carcass. This is essential for tall chests of drawers to allow a clear top-down view into the highest drawers.
Ball-bearing runner: Side-mounted metal telescopic slides. They provide high lateral stability.
Undermount runner: Mounted concealed beneath the drawer base. It provides a clean appearance and offers better support against deflection on wide drawers.

Pay attention to convenience features: Soft-close (damping during closure) and push-to-open (release by pressing the front) are mechanically opposing systems. Combining them requires specialist, synchronised fittings; otherwise, you must opt for one system or the other.

3. Hinges (for Combination Models)

If the furniture unit features doors in the upper section, concealed cup hinges are used. The standard drill hole for the cup is 35 mm. The mounting type is chosen depending on the position of the door on the carcass:

Full overlay: The door rests fully over the carcass side edge.
Half overlay: Two doors share a central carcass partition (half overlay).
Inset: The door sits flush within the carcass side panels.

The standard opening angle is 110°. To prevent doors from slamming, a door damper can be retrofitted or a hinge with an integrated soft-close piston can be selected.

4. Joining Technology and Drilling Grids

Most flat-pack constructions are based on the System 32, a standardised line of holes with a 32 mm drilling pitch. This simplifies repositioning shelf supports (typically 3 mm or 5 mm hole diameters). The carcass itself is pulled together under tension using cam and pin connectors (Minifix) combined with wooden dowels. For permanently heavy-duty connections, threaded inserts (insert nuts) and metric machine screws are recommended.

Types and Options at a Glance

The technical specifications of the cabinets vary depending on where they are used:

Drawer chests (e.g. 8 drawers): Offer maximum compartmentalisation. With a typical carcass height of 1200 mm and 8 drawers, this results in a front height of approx. 140 mm per drawer. Precise alignment of the front reveal gaps via the 3D adjustment of the runners is essential here.
Slim hallway chests: Often only 300 mm deep and 700 mm wide. They serve as shoe or storage units. Here, a slim hallway cabinet is usually fitted with flap stay fittings instead of conventional drawers.
Decors and material variations: Whether melamine resin coated in anthracite, black, white, or wood decors (such as Sonoma Oak) – the surfaces dictate the edge banding. ABS edging (usually 1 mm or 2 mm thick) protects the edges against impact and moisture.

Which Model for Which Application? (Decision Guide)

When space in the entrance area is tight: Choose a slim cabinet with a maximum depth of 300 mm. Pay attention to flap stay mechanisms or extremely short drawer runners (250 mm).
When heavy items (tools, files) are stored: Select a model with a maximum width of 700 mm to minimise shelf sagging. Ensure ball-bearing runners with at least 30 kg load capacity are used.
When the furniture unit is placed in damp rooms (bathrooms): Look for all-round sealed ABS edging and galvanised or powder-coated fittings to prevent corrosion.
When a handleless design is required: Plan for runners with a push-to-open mechanism. If a mechanical pull is desired, at least one furniture handle must be fitted centrally or asymmetrically per front.

Installation Advice: Assembly and Tilt Protection

A tall, narrow carcass acts structurally like a lever arm: pulling out the upper, fully loaded drawers shifts the centre of gravity drastically forward. The furniture unit will inevitably tip over. Wall anchoring is therefore not just a recommendation, but a technical necessity.

Tools Required:

Cordless screwdriver with driver bits (PZ, PH, TX)
Spirit level and folding rule or tape measure
Hammer drill and masonry drill bit (for wall mounting)
Rubber mallet (for wooden dowels)

Step-by-Step Assembly:

Base and side assembly: Join the base panel to the side panels. Use the designated furniture connectors for this. Tighten the cam casings hand-tight using a PZ2 screwdriver (approx. 180° turn).
Inserting the back panel: The back panel squares up and stabilises the carcass. Before fixing it in place, check the diagonals of the carcass (both diagonal measurements must be millimetre-identical).
Fitting the feet: Attach the plinth feet. To compensate for uneven flooring, adjustable furniture feet with M8 or M10 threads are ideal. These allow exact levelling.
Wall fixing: Position the carcass against the wall. Mark the drill holes for the anti-tilt brackets (steel angle brackets). Use suitable wall plugs for wall mounting and secure the bracket to the furniture unit with matching wood screws and furniture screws (e.g. 4 x 15 mm round head).
Inserting the drawers: Insert the drawers from bottom to top and align the fronts using the adjustment screws on the runners until a uniform gap pattern (approx. 2 mm to 3 mm) is achieved.

Frequently Asked Questions (FAQ)

What is the minimum depth a tallboy should have? The technically sensible minimum depth is 300 mm (external dimension). This allows the installation of 250 mm drawer runners. At shallower depths, drawers can no longer be guided reliably; flap hinges must be used instead.

How do I level a cabinet on an uneven floor? Use height-adjustable plinth feet. These can be adjusted continuously via a thread (typically +15 mm to +20 mm). Always level the carcass with a spirit level; otherwise, the carcass will rack and the drawer runners will bind.

Why are my drawers sticking after assembly? In most cases, the carcass has not been assembled square (check diagonals) or is not precisely level. Over-tightening the fixing screws on the ball-bearing runner can also distort the slide profile and obstruct smooth running.

Can I replace partial-extension runners with full-extension runners? Yes, provided the installation width (the clearance between the drawer side and the carcass interior) is identical. Standard ball-bearing runners usually require an installation clearance of 12.7 mm to 13 mm per side. The drilling positions in the System 32 grid can generally be reused.

Which screws should I use for fittings? For mounting runners and hinge mounting plates in chipboard, use Euro screws (Ø 6.3 mm for 5 mm pre-drilled holes) or standard countersunk woodscrews (Ø 3.5 mm to 4 mm) with PZ or TX drive.
