How Big Should My Wardrobe Be?

A wardrobe should be around 600mm deep, tall enough to use the room’s height without touching the ceiling, and wide enough to give each adult 900mm to 1200mm of hanging rail. In a typical UK double bedroom that usually means a unit between 900mm and 1500mm wide for one person and 1800mm or more for a couple. Depth is the fixed figure: it does not change with room size, because it is set by the width of a coat hanger.

Getting the size right is a balance between what you need to store and what the room can carry without becoming difficult to use. A wardrobe that holds everything but blocks the walkway is the wrong size, however generous the storage looks on paper. The sections below work through both sides of that balance.

Depth Comes First

Internal depth of 570mm to 600mm allows a hanger to sit front to back with clothing hanging freely and the doors closing without pressure. Add the door thickness and you arrive at an external depth of roughly 600mm to 630mm, which is why almost every wardrobe you look at lands in that range.

You can go shallower, down to around 350mm, by fitting a front to back rail where garments hang facing sideways. This works in a narrow room and is a legitimate solution, but capacity drops considerably and access is less convenient. It is a compromise for tight spaces rather than a first choice.

Going deeper than 650mm rarely helps. The extra depth becomes space at the back that you cannot reach without moving everything in front of it, and it eats into the floor area of the room.

Choosing the Height

Use the room’s height. In a standard UK bedroom with a ceiling around 2400mm, a wardrobe of 1900mm to 2100mm makes good use of the wall while leaving a gap that keeps the unit from looking wedged in.

Two practical considerations affect this. First, anything above roughly 1900mm needs a step to reach, so treat the top section as long term storage for bedding, luggage and out of season clothing rather than daily use. Second, a freestanding unit has to be tilted upright in the room, so its diagonal must clear your ceiling. Measure that before ordering a tall unit, particularly for an upstairs room or a loft conversion where the ceiling may be lower than you assume.

Where a wardrobe reaches close to the ceiling, a filler panel across the top removes the dust ledge and makes the unit read as part of the room. Where the ceiling slopes, a lower unit set under the slope, or a run of storage stepping down with the roofline, uses the space far better than forcing a full height unit against the tallest wall.

Working Out the Width You Need

Width is where your own clothing decides the answer. Push everything currently hanging together tightly, measure the rail length it occupies and add around 20 per cent. That is your genuine hanging requirement, and it is far more accurate than any general figure.

As a guide, one adult is usually well served by 900mm to 1200mm of rail alongside shelving, and two adults by 1800mm to 2400mm. Remember that a wardrobe’s external width is not all rail: side panels, a central divider and any drawer bank reduce the usable figure by 50mm to 100mm.

Double hanging changes the arithmetic significantly. Fitting two short rails on one side, each with around 1000mm of clear height, doubles the rail in that section. A 1000mm wide unit with double hanging on one side and long hanging on the other can hold as much as a 1500mm unit with a single long rail throughout.

Fitting It Into the Room

The room sets limits that clothing volume cannot override. Leave around 700mm of clear floor in front of a hinged wardrobe so the door opens fully and you can stand there comfortably. Sliding doors need barely any clearance, which is why they suit rooms where the bed sits close to the wall.

Check the walkway around the bed as well. A gap under about 600mm alongside a bed becomes uncomfortable to use daily, and a wardrobe that reduces it below that will be a persistent irritation regardless of how much it stores.

Mark the footprint on the floor with masking tape before ordering, and open a mental door in the marked space. Two minutes of tape prevents the most common sizing mistake, which is a unit that fits the wall perfectly and makes the room awkward to move through.

Also consider what the wardrobe sits next to. A tall unit beside a window can block light, and a wardrobe placed against an external wall in a poorly ventilated room can trap condensation, so leave a small air gap behind it.

Guidance by Room Type

In a main bedroom, prioritise width over height. A wider unit with mixed hanging heights, drawers and adjustable shelves is more useful than a very tall narrow one, and it is easier to live with.

In a box room, and many UK second bedrooms are genuinely tight, a single wardrobe combined with under bed storage and a chest of drawers often gives more usable capacity than one large unit that dominates the floor. Our 2 door wardrobes UK sale options work well in that role, and a separate piece from our modern chest of drawers UK sale range takes folded clothing more efficiently than shelves in a hanging space.

In a guest room, keep it modest. Around 600mm of clear rail, a shelf and a few spare hangers cover most visitors, and the floor space is better left to the room.

In a children’s room, choose adjustable internal fittings over a specific layout. Short garments suit double hanging from an early age, and drawers matter more than rail length, but the requirement will change several times over the years.

When Bigger Is Not Better

Extra size is only useful if it is well organised. A large wardrobe with one long rail and a single top shelf wastes the space beneath short garments and above the shelf, while a smaller unit with double hanging, drawers and adjustable shelves uses every millimetre.

Before sizing up, try the measures that cost nothing. Standardise your hangers, which commonly frees a third of the rail. Add a second rail under short hanging. Use the dead height above the top shelf. Rotate out of season clothing into breathable bags. If overflow remains after an honest edit, the storage genuinely is undersized.

When you do buy, choose on internal layout as much as external dimensions. Our modern wardrobes UK sale range includes hinged and sliding designs with combined hanging and shelving, and where floor space in front is limited the sliding wardrobes UK sale designs remove the swing clearance entirely. It is worth planning the whole room together rather than piece by piece, and our bedroom furniture UK sale collection is grouped by style at Furniture in Fashion, with free delivery to most UK mainland postcodes.

A Short Checklist Before You Order

Measure the wall width available and deduct anything you want to keep clear. Confirm the ceiling height and the carcass diagonal. Confirm 600mm of depth is available without narrowing the walkway below 600mm. Measure your existing hanging rail usage and add 20 per cent. Check the delivery route: doorways, stair turns and landings. Then mark the footprint with tape and live with it for a day.

That sequence takes half an hour and removes almost every sizing regret people have after a wardrobe arrives.

Frequently Asked Questions

What is a standard wardrobe size?

Most freestanding wardrobes are around 600mm deep and 1800mm to 2100mm tall, with widths commonly between 500mm for a single door and 1800mm or more for four doors.

How deep should a wardrobe be?

Around 600mm externally, giving 570mm to 600mm inside so hangers sit front to back. Shallower units need a front to back rail, which reduces capacity noticeably.

Should a wardrobe reach the ceiling?

It can, and it adds storage while removing the dust ledge, but a freestanding unit must be able to tilt upright under the ceiling. Leaving a gap of around 100mm makes installation far simpler.

How much space do I need in front of a wardrobe?

Around 700mm for hinged doors, so the door can open fully and you can stand in front of it. Sliding doors need very little, which makes them suitable for narrow rooms.

Is a taller wardrobe better than a wider one?

Usually not. Height above roughly 1900mm needs a step to reach and suits long term storage only. A wider unit with mixed hanging heights and drawers is more usable day to day.
