Built-in Wardrobe in an Alcove: Made-to-Measure Wardrobe Rails & Hinges for the Bedroom

A built-in wardrobe in a wall alcove requires fittings planned down to the millimetre, where the load capacity of the wardrobe rail and the opening angle of the concealed hinges are matched precisely to the depth of the space and the door width.

Planning a custom alcove wardrobe in the bedroom places high technical demands on the choice of furniture hardware. When the carcass sits flush with the walls, internal storage fittings and door mechanics must be matched exactly to the available internal dimensions. This guide defines the technical specifications for wardrobe rails and hinges, ensuring smooth installation and durable mechanical performance under load.

Made-to-Measure Wardrobe Rails: Key Purchasing Criteria

The wardrobe rail is the structural backbone of internal wardrobe fittings. Its dimensions depend directly on the carcass width and the planned weight load.

Profile Shape and Deflection

The profile determines the bending stiffness of the metal. For short distances up to 600 mm, a round tube with a diameter of 25 mm is often sufficient. For wider carcass sections, an oval tube (typically 30 mm x 15 mm) is strictly preferable. Due to the vertical orientation of the oval, loads are distributed better, minimising deflection under heavy winter coats.

Span and Centre Supports

For alcove wardrobes running across the entire width of a wall, rails measuring from 2000 mm up to 3000 mm (3 metres) are often used. From a clear span of 1000 mm upwards, a centre support must be installed. This is screwed into the shelf above and prevents the rail from sagging. Without this central support, full loading causes material fatigue in the lateral wardrobe rail brackets.

The Correct Wardrobe Depth

A standard clothes hanger requires an internal carcass depth of at least 550 mm, ideally 600 mm, to ensure garment sleeves do not get caught when closing the door. If the alcove is shallower, standard transverse rail installation will not work.

Overview of Wardrobe Rail Types

Depending on alcove depth and usage requirements, different systems are used.

Static Wardrobe Rails

The standard choice for wardrobes with a depth of 550 mm or more. Fixing is achieved via lateral flanges (wardrobe rail brackets) compatible with the System 32 (hole line) pattern of the side panels. Securing is usually done with screws (drive PZ or TX) with a diameter of 3.5 mm or 4 mm.

Pull-Out Wardrobe Rails (Frontal Pull-Out)

For alcoves that are only 350 mm - 500 mm deep, a pull-out wardrobe rail is the technically correct solution. Here, hangers hang one behind the other. The runner is screwed beneath the shelf. Two guide technologies are available:

• Partial extension: The rail pulls out to roughly 75%. The rear section remains inside the carcass.
• Full extension: The rail extends 100%. This requires sturdier ball bearing or roller runners but offers full access to the rearmost garment.

Wardrobe Lift (Pull-Down Rail)

For ceiling-height built-in wardrobes (over 2200 mm in height), a pivoting lift is recommended. Using a pull rod and integrated gas struts (force rated in Newtons), the entire rail is swung downwards and forwards. Load capacity here is typically limited to 10 kg - 15 kg.

Hinges for Alcove Wardrobes: Which One for Which Application?

If the alcove wardrobe is fitted with classic hinged doors, selecting the correct concealed hinges / cabinet hinges is crucial. The standard cup diameter is 35 mm. The cup hole in the door is drilled using a Forstner bit to a precise depth of 13 mm - 15 mm.

An alcove wardrobe functions like clockwork: if a single component (such as a hinge) is positioned incorrectly, the entire mechanism binds. Therefore, the mounting type must be selected with precision:

Full Overlay (Standard Overlay Door)

If the door is meant to cover the side carcass panel completely, a full overlay hinge is used. In alcove wardrobes, this means the wardrobe door sits almost flush with the adjoining room wall. A reveal (gap) of at least 2 mm - 3 mm to the wall must be planned so the door does not scrape against wall coverings when opening.

Half Overlay (Twin Door Mounting)

When two doors hinge on a single central partition panel of the carcass (twin doors), half overlay hinges are required. The crank of the hinge arm ensures the door covers only half the front edge of the partition (typically 8 mm on a 16 mm thick chipboard panel).

Inset (Internal Door)

If the door is to sit flush inside the carcass opening between the side panels, choose an inset hinge. The front edges of the carcass remain visible.

Opening Angle and Internal Drawers

The standard opening angle for wardrobes is 110°. Standard concealed hinges / cabinet hinges 110 degrees are suitable for simple shelving and hanging rails.

However, if internal drawers on telescopic runners are planned in the lower section of the wardrobe, a 110° hinge is insufficient. The open door will protrude into the travel path of the drawer. In this case, wide-angle hinges (often called zero-protrusion hinges) must be fitted. For this, concealed hinges / cabinet hinges 165 degrees or 155° are used. These pivot the door completely clear of the internal carcass opening.

For maximum operating comfort, concealed hinges / cabinet hinges with soft close should be used. An integrated hydraulic damper decelerates the door during the final degrees of its closing path and pulls it gently shut against the carcass.

Alternative When Space Is Limited: Sliding Doors

If the distance between the built-in wardrobe and the bed is too small to open hinged doors fully (less than 600 mm of clear space), switching to custom wardrobe sliding doors is necessary. In this setup, concealed hinges are omitted entirely. Instead, top and bottom tracks are installed, guiding the door panels on ball-bearing rollers.

Installation Notes for Wardrobe Rails and Concealed Hinges

For the professional installation of wardrobe rails and hinges, keep the following technical parameters in mind:

1. Height position of the wardrobe rail: The clearance between the top edge of the wardrobe rail and the shelf above must be at least 40 mm - 50 mm. If the gap is smaller, hanger hooks cannot be hooked over or removed.
2. Mounting the cruciform mounting plate: Base plates for concealed hinges are generally screwed to the carcass interior using the 32 mm system grid. The standard distance from the front carcass edge to the centre of the first drilled hole is 37 mm.
3. Number of hinges: A wardrobe door measuring 2000 mm in height and 600 mm in width (made from 18 mm thick chipboard) weighs around 15 kg. This strictly requires 4 to 5 concealed hinges to prevent door sag.
4. Adjustment: Modern concealed hinges feature 3D adjustment. Using eccentric screws on the hinge arm, height, depth, and lateral reveal can be adjusted to the millimetre for a neat, uniform gap pattern.

Frequently Asked Questions (FAQ)

What diameter is ideal for a wardrobe rail? For standard loads, a round tube with a 25 mm diameter is suitable. For heavier loads or spans exceeding 800 mm, an oval tube measuring 30 mm x 15 mm is preferred, as it offers greater resistance to bending.

When must I use a pull-out wardrobe rail? Whenever the internal depth of the wardrobe carcass is less than 500 mm. Because standard coat hangers will not fit across the depth, a front-facing pull-out rail allows clothes to be hung one behind the other.

How many concealed hinges do I need for a wardrobe door? This depends on door height and weight. As a guideline: up to 900 mm height requires 2 hinges, up to 1600 mm requires 3, up to 2000 mm requires 4, and for full-height doors up to 2400 mm, 5 hinges should be fitted.

Which hinge do I need if there are internal drawers in the wardrobe? In this case, a wide-angle hinge with an opening angle of 155° or 165° (zero protrusion) is strictly required. Only this allows the door panel to swing fully clear of the internal carcass opening, preventing drawers from colliding with the inside of the door when pulled out.

Can I install a 3-metre wardrobe rail without a centre support? No. Across a free span from 1000 mm, the rail will sag under the weight of clothing. At a length of 3000 mm, at least two, and ideally three centre supports must be installed and secured to the shelving above.
