The short answer

The numbers that matter.

Keep at least 900mm of clear walkway. With 600mm deep cabinets, a walk-in with cabinets on one wall needs about 1500mm of width, and one with cabinets on both walls about 2100mm. For hanging, one designer sets long-hanging rails at about a 1700–1900mm drop and shirt rails at about 1000mm.^[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.

The sizes

Sizes in millimetres, with sources.

Each row links to the source it came from.

Width and walkway

Walkway first, then the cabinets either side.

Element	Size	Source
Clear walkway	at least 900mm	[1]
Cabinet depth along each wall	600mm	[1]
One-sided walk-in (600mm cabinets + 900mm walkway)	at least 1500mm wide	[1]
Two-sided walk-in	about 2100mm wide	[1]
Two-sided, to avoid feeling cramped	2100–2500mm	[3]
Corridor width, accessibility guideline (Silver / Gold level)	1000mm / 1200mm	[5]
Doorway clear opening, same guideline (Silver / Gold level)	820mm / 850mm	[5]

Cabinet depth

The sources disagree, so both are shown.

Element	Size	Source
Adult hanger width	about 450mm	[1]
Minimum cabinet depth for adult hanging (one maker)	600mm	[1]
Walk-in cabinet depth (one designer)	at least 500mm, ideally 520–550mm	[2]

Hanging and drawers

Adjust for the height of the person using the robe.

Element	Size	Source
Rail drop for full-length items	about 1700–1900mm	[2]
Rail drop for shirts and similar	about 1000mm	[2]
Drawer height for smalls	220–300mm	[2]

Built-in robes, for comparison

What NSW social housing requires in the bedrooms it builds.

Element	Size	Source
Main bedroom built-in robe (depth × length)	600 × 1800mm	[4]
Other bedrooms	600 × 1200mm	[4]
Linen cupboard, with shelves	600 × 450mm	[4]

Worked example

Check your room.

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

Two-sided: 600mm + 900mm walkway + 600mm = 2100mm. With 520mm cabinets, as one designer uses: 520 + 900 + 520 = 1940mm.
One-sided: 600mm + 900mm walkway = 1500mm.
Long hanging: a rail at a 1700–1900mm drop needs that much clear height below it, so hang your longest coat or dress and measure it before fixing the rail.
Measure the room at three heights and use the smallest width (see how to measure a room).

What we could not verify

Limits of this guide.

We found no Australian Standard that sets walk-in robe sizes or rail heights. These are makers' and designers' figures.
The sources disagree on cabinet depth (600mm against 500–550mm). Measure your widest-shouldered jacket on its hanger before choosing.
The corridor and doorway widths are from a voluntary accessibility guideline (Livable Housing Australia), shown as a cross-check, not as a walk-in requirement.
The built-in robe sizes are NSW social housing requirements for its own homes, not a rule for private homes.
