Standard Wardrobe Dimensions Australia (mm)

The short answer

The numbers that matter.

A built-in wardrobe in Australia is most commonly 600mm deep, because an adult coat hanger is about 450mm wide and needs to hang square without touching the doors. A 450mm depth suits linen, shelving or children's clothes, not adult hanging. A walk-in needs at least 900mm of clear walkway, so cabinets on both sides need roughly 2100–2500mm of room width. NSW social housing specifies a 600 × 1800mm built-in robe in the main bedroom.^[1]^[2]

These are common sizes and published guidance, not rules. Every cabinet can be sized to the room and the people using it. Confirm appliance and fixture sizes against the exact model you buy.

Built-in wardrobe

Depth is set by the hanger, not by the door.

Element	Size	Source
Most common built-in depth	600mm	[1]
Minimum depth for adult hanging	600mm	[1]
Adult coat hanger width	about 450mm	[1]
Shallow cupboard (linen, shelves, kids' clothes)	about 450mm	[1]
Deeper option some people choose	up to 650–700mm	[1]

Built-in robe sizes in NSW social housing

What one state housing agency requires in the homes it builds.

Element	Size	Source
Main bedroom built-in robe (depth × length)	600 × 1800mm	[2]
Other bedrooms	600 × 1200mm	[2]
Linen cupboard, with shelves	600 × 450mm	[2]

Walk-in wardrobe

The walkway decides whether a walk-in works.

Element	Size	Source
Cabinet depth along each wall	about 600mm	[1]
Clear walkway	at least 900mm	[1]
Room width for cabinets on both sides	at least 2100–2500mm	[1]
Corridor width in an Australian accessibility guideline (Silver level)	1000mm	[3]

Worked example

Check your own room.

Simple arithmetic on the figures above. Swap in your own measurements.

Two-sided walk-in: 600mm cabinets + 900mm walkway + 600mm cabinets = 2100mm wall to wall, before any end panels or skirting. That is the low end of the 2100–2500mm range above.
One-sided walk-in: 600mm cabinets + 900mm walkway = 1500mm.
Measure the room at three heights and use the smallest width (see how to measure a room).

How Carcasso draws it

Height zones and hanging rails.

Carcasso's wardrobe drawings stack these zones from the floor up.

Kickboard: 100mm or 130mm
Door zone: 1850mm
Bulkhead above: 20 to 300mm

Where the library places hanging rails, measured from the floor:

Single hang for dresses, coats and long shirts: 1700mm
Long hang behind doors with a top box above: 1900mm
Double hang: lower rail 1050mm, upper rail 2100mm
Short hang over a three-drawer stack: 1200mm

A shirt or jacket needs about 1000mm between rails, and nothing longer than about 1000mm should go on the bottom rail of a double hang. Carcasso warns you when two rails are less than 800mm apart.

What we could not verify

Limits of this guide.

We found no Australian Standard that sets wardrobe depths or hanging-rail heights. The figures above are industry practice, not code.
Rail heights depend on your longest garment and the ceiling, so we have not printed a single "standard" rail height. Hang your longest item and measure it.
The NSW social housing robe sizes are that agency's requirements for its own homes, not a rule for private homes.
The 1000mm corridor figure is from a voluntary accessibility guideline (Livable Housing Australia), shown only as a cross-check on the 900mm walkway.

Questions

Common questions.

How deep is a standard built-in wardrobe in Australia?

The most common built-in wardrobe depth in Australia is 600mm. That depth lets an adult coat hanger, about 450mm wide, hang straight without pressing against the doors.

Can a wardrobe be 450mm deep?

Yes, but a 450mm deep cupboard generally suits linen, shelving or children's clothing rather than adult hanging, because an adult hanger is about 450mm wide.

How wide does a walk-in wardrobe need to be?

Allow at least 900mm of clear walkway. With 600mm deep cabinets on both sides, that means a room at least 2100mm wide, and 2100–2500mm is the commonly quoted range.

Is there an Australian Standard for wardrobe sizes?

We could not find an Australian Standard that sets wardrobe depths or hanging-rail heights. NSW social housing does set robe sizes for the homes it builds: 600mm by 1800mm in the main bedroom and 600mm by 1200mm in other bedrooms.
