Standard Wardrobe Measurements: Sizing for Internal Fittings
Planning a wardrobe that looks smart on the outside while remaining highly functional inside comes down to precise dimensions. Whether you are building bespoke cabinetry from scratch or upgrading an existing flat-pack unit, understanding standard wardrobe measurements is essential before ordering internal fittings. Getting your sizing right ensures clothes hang freely, pull-out storage units clear the doors, and every centimetre of internal space is utilised effectively.
Standard External and Internal Wardrobe Depths
The overall depth of a wardrobe dictates the type of internal organisation you can use. For standard full-depth hanging space, the external depth typically sits between 580 mm and 650 mm.
- Hanging depth: A standard adult coat hanger requires an internal depth of at least 550 mm. If your internal depth is less than 500 mm, garments will catch against the front doors when closed.
- Shallow depth solutions: In alcoves or tight bedrooms where internal depth is under 500 mm, standard longitudinal rails cannot be used. Instead, front-to-back pull-out wardrobe rails are fitted to hang clothes facing forward.
- Internal carcass allowance: Always deduct the thickness of the carcass panels (typically 18 mm MDF or MFC) and the door overlay or sliding track recess to determine your usable internal depth.
Vertical Sizing: Rails and Shelf Clearances
When calculating the vertical measurements of wardrobe interiors, different clothing items demand specific vertical drops:
- Full-length hanging: Long dresses, overcoats, and evening wear require between 1500 mm and 1700 mm of vertical hanging space below the rail.
- Short hanging: Shirts, blouses, trousers, and folded jackets generally need between 900 mm and 1050 mm.
- Double hanging configurations: By dividing a carcass into two vertical sections, you can install two short hanging rails one above the other, provided the internal carcass height is at least 2000 mm to 2100 mm.
- Rail mounting clearance: Ensure you leave a minimum of 50 mm clearance between the top of the wardrobe rail and the bottom of the shelf above it to allow coat hanger hooks to lift off easily.
Planning for Drawer Runners and Pull-Out Baskets
Installing internal drawers and wire baskets requires careful attention to internal carcass width and depth. Drawer runners come in standardised lengths (usually starting at 250 mm and increasing in 50 mm increments up to 550 mm or 600 mm).
To avoid fitment issues, choose a runner length that is at least 10 mm to 20 mm shorter than your internal carcass depth. For internal pull-outs, bottom-mounted or side-mounted soft-close runners provide smooth movement, but you must ensure the unit is built to the exact internal width required by the runner specifications.
Hinge Protrusion and Clearance Spacers
One of the most frequent joinery oversights is failing to account for door hinges. When standard concealed cabinet hinges (35 mm cup) are fitted, the hinge arms protrude into the internal carcass opening by approximately 20 mm to 35 mm when the door is open at 90 degrees.
If you fit a pull-out basket or internal drawer flush against the carcass side, it will collide with the hinge arm or the door leaf. To solve this, either fit wide-angle hinges (such as 155° or 165° zero-protrusion hinges) which swing the door completely clear of the internal opening, or install timber packer strips behind the drawer runners on the hinged side.
Frequently Asked Questions
What is the ideal width for wardrobe shelves?
Wardrobe shelves typically span between 400 mm and 800 mm. For spans exceeding 800 mm in 18 mm board, add a central support or vertical divider to prevent the shelf from sagging under heavy loads.
How high should a top shelf be installed?
A top shelf above a standard short hanging rail is normally positioned between 1700 mm and 1800 mm from the floor, leaving enough space beneath for garments while providing upper storage for seasonal boxes or spare bedding.
