Planning a 50 cm Deep Wardrobe: Space-Saving Fittings and Hardware

May 16, 2026

A wardrobe with a 50 cm depth requires precisely matched fittings such as 450 mm runners and wide-angle hinges, as the usable interior space for standard coat hangers is strictly limited.

Building cabinet furniture with a reduced depth presents fitters and joiners with specific challenges. While the standard dimension for wardrobes is 600 mm, a wardrobe 50 cm deep requires an exact calculation of the internal depth. Since standard clothes hangers have a width of around 450 mm, barely any clearance remains with a usable carcass depth of around 480 mm. Selecting the right furniture fittings determines whether doors close flush, drawers utilise the maximum space, and the overall construction remains stable.

This guide covers the technical specifications that must be observed when planning and fitting out the interior of a 500 mm deep cabinet.

Key Purchasing Criteria for Shallow Wardrobes

When selecting fittings for the interior fit-out, the physical limitations of the carcass must be strictly adhered to. Every millimetre determines functionality.

Correct Nominal Lengths for Drawer Runner Systems

The nominal length of a drawer runner defines the required depth space. In a cabinet with an external depth of 500 mm and a standard back panel (set into a groove, approx. 15 mm to 20 mm from the rear edge), around 480 mm of clear internal depth remains. Here, a runner with a 450 mm nominal length is the correct size. A 500 mm runner would collide with the back panel.

Hinge Technology and Opening Angles

Concealed cup hinges are generally used for hinged wardrobe doors. The standard cup diameter is 35 mm. With narrow carcass designs, the opening angle is critical: a standard hinge with 110° is sufficient for normal applications. However, if internal drawers are to be installed, a wide-angle hinge with 155° or 165° is mandatory. This swings the door completely clear of the internal opening, preventing the drawer from catching against the inside of the door when pulled out.

Door Overlay Types

The position of the door relative to the carcass determines the hinge geometry:

Full overlay: The door completely covers the carcass side panel (standard for individual carcasses).
Half overlay / twin: Two doors share a single central carcass divider (typical for multi-section wardrobes).
Inset: The door sits flush inside the carcass sides.

Load Capacity of Fittings

Clothing, especially winter jackets or thick stacks of knitwear, creates significant weight. Drawer runners for bedroom cabinetry should feature a dynamic load rating of at least 30 kg. For very wide drawers from 800 mm width upwards, heavy-duty runners rated at 45 kg are recommended.

Overview of Interior Fitting Types and Options

Matching wardrobe accessories and the corresponding fittings define the usability of the furniture. The following systems are available for 50 cm deep constructions.

Drawer Runners

Ball bearing runner: Mounted to the side of the drawer. It consists of telescopic rails with steel ball bearings. It is robust, but requires an exact lateral installation clearance of typically 12.7 mm per side.
Undermount runner: Mounted concealed beneath the drawer base. It provides a clean aesthetic and exceptional running performance.
Full extension vs. single extension: A full extension runner pulls out 100% from the carcass, which massively simplifies access to the rear area in 450 mm deep drawers. A single extension stops at approximately 75% of the travel.

Damping and Opening Mechanisms

Soft-close: A hydraulic or pneumatic damper slows the drawer or door down over the final few centimetres and pulls it shut gently and silently.
Push-to-open: A mechanical ejector triggered by pressing the front panel. Note: This is the exact opposite of soft-close. These two systems cannot be combined in the same mechanical runner fitting.

Wardrobe Rails and Brackets

Oval wardrobe rails made from steel or aluminium are the standard choice. Fastening is achieved using wardrobe rail sockets, which are either plugged into the 32 mm system hole pattern or fixed with chipboard screws (drive PZ or TX, diameter 3.5 mm or 4 mm). The distance from the top edge of the shelf to the rail should be at least 40 mm so that hanger hooks can be placed easily.

Which Fitting for Which Scenario? (Decision Guide)

The choice of hardware depends on the specific setup and spatial conditions.

If the cabinet is equipped with internal drawers, then wide-angle hinges with a 155° opening angle and full extension runners must be fitted to avoid collisions.
If the space in front of the wardrobe is extremely narrow, then custom wardrobe sliding doors are suitable. Caution: A sliding door system consumes between 50 mm and 80 mm of internal depth. In a 50 cm deep cabinet, only approx. 400 mm remains inside. Standard clothes hangers will no longer fit sideways on a rail. In this case, a pull-out wardrobe rail (front-facing pull-out) must be installed.
If a corner solution is being built, then the corner wardrobe requires special angled cup hinges (e.g. 45° or 90° blind corner hinges) to guide the folding doors correctly against the corner post.
If the wardrobe is planned even shallower (e.g. as a wardrobe 45 cm deep or wardrobe 40 cm deep), then the classic wardrobe rail is omitted completely in favour of telescopic pull-out clothes rails.

Installation Notes for Cabinet Assembly

Precise installation determines the door gap alignment and the longevity of the fittings. In modern furniture production, everything is based on a standardised grid. The System 32 functions as an architectural framework that accurately sets the position of all fittings, from the hinge mounting plate to the shelf support. The hole spacing is 32 mm, with the distance from the front carcass edge to the first row of holes measuring exactly 37 mm.

Required Tools

For the professional installation of interior fittings, the following tools are required:

Cordless drill/driver
Forstner bit (diameter 35 mm) for hinge cup drillings
Wood drill bit (diameter 5 mm) for shelf supports and Euro screws
Cross-line laser or spirit level for the precise alignment of wide carcass sections, such as on a wardrobe 120 cm wide
Screwdrivers or driver bits in PZ2 or TX20

Step-by-Step Installation of a Drawer Runner in System 32

Positioning: Align the cabinet profile along the 37 mm row of holes.
Fastening: For pre-drilled holes (diameter 5 mm), secure using special Euro screws. For undrilled carcass sides, use chipboard screws (e.g. 4 x 16 mm).
Drawer installation: Screw the drawer profile to the drawer side (for ball bearing runners) or underneath the base (for undermount runners).
Insertion and adjustment: Hook the drawer into place. Modern undermount runners feature 3D adjustment clips that allow tool-free adjustment of the front in height, side, and tilt by ±2 mm in each direction.

Frequently Asked Questions (FAQ)

Do standard coat hangers fit into a 50 cm deep wardrobe? Yes, standard clothes hangers measure approximately 450 mm in width. With an external depth of 500 mm and a recessed back panel, approximately 480 mm of clear internal depth remains. The hangers fit precisely, though bulky coats must not obstruct the doors when closing.

Which drawer runners do I need for a 50 cm depth? For a carcass with an external depth of 500 mm, a drawer runner with a nominal length of 450 mm is required. This ensures that the runner does not strike the back panel and leaves sufficient space for the drawer front.

How do I choose the correct cup hinge for my wardrobe door? If the door sits flush over the outer cabinet side panel, you require a hinge for a full overlay. The required cup hole diameter in the door is generally 35 mm.

Can I install sliding doors on a 50 cm deep wardrobe? Yes, this is technically feasible, but it changes how the space is used. Sliding door gear requires between 50 mm and 80 mm of space inside the cabinet. The remaining internal depth is then insufficient for standard transverse clothes hangers, requiring front-facing pull-out rails instead.

What is the difference between full extension and single extension? A full extension runner allows the drawer to be pulled 100% clear of the cabinet, granting full access to the rear area. A single extension runner only extends to around 75%, leaving the rearmost part of the drawer inside the carcass.
