A half height wardrobe is the answer to a sloped ceiling
Summary: A half height wardrobe is for places where a normal wardrobe cannot stand up: sloped ceilings, low windows, hallway walls, and converted attics. The useful question is how much hanging height you can get without wasting the low space.
The flat had a knee wall. That's the bit of a converted attic where the ceiling slopes down to meet the floor at about a metre off the deck, and the only thing you can do with the space is stare at it. My friend Marieke had been staring at hers for a year. She owned eleven shirts on hangers and had nowhere to put them. Every wardrobe at IKEA was just over 2 m tall. Her ceiling at the back wall was 1.14 m and getting shorter.
What she eventually had made from pre-cut panels, after five Saturdays of measuring and one regrettable trip to a kitchen showroom, was 1.08 m tall, 1.84 m wide, and tucked under the slope. Half height. Hanging rail behind one door, four drawers behind the other. The shirts hang. Problem solved.
Half height wardrobes are the answer to a specific question: how do you store clothes in a space that isn't tall enough for a normal wardrobe?
What "half height" actually means
There's no British Standard for this, but the term covers wardrobes that are roughly half the height of a typical full-height one. In practice that's anything between 90 cm and 1.3 m tall. Full-height wardrobes start around 1.8 m and most of them push past 2 m because the second hanging rail or the top shelf wants the room.
Half height kills the second rail. You get one hanging zone, usually 85 cm to 1 m of internal hanging height, which is enough for shirts and folded trousers but not enough for a long coat. You get a top surface you can put things on. You get the option of drawers underneath the rail instead of above it.
The depth is usually the same as a normal wardrobe. Hangers want 58 to 60 cm of internal depth, which means an external depth of around 60 to 62 cm. Going shallower is possible if you hang things sideways on a pull-out rail, but pull-out rails on a half height wardrobe feel like solving the same problem twice.
Where they actually go
Five places they earn their keep, and one where they don't.
Under a sloped ceiling. The classic case. A converted loft with a kneewall at 1.1 m gets a 1 m tall wardrobe with maybe 8 cm of clearance for cornicing and hand-fitting. You measure the lowest point of the slope above where the wardrobe sits, not the highest, and then you knock 5 to 10 cm off that for tolerance.
Under a window. A half-height wardrobe that runs to about 10 cm below a windowsill turns the wall under the window from dead space into hanging storage and gives you a top surface for a reading lamp. Sill heights vary wildly. In a 1930s Dutch row house I measured one at 92 cm, in a Berlin Altbau at 1.26 m, and in a 1970s flat at 1.05 m. None of those numbers match anything in a catalogue.
In a kid's room. Children don't need 2 m of hanging space. A 1.1 m tall wardrobe puts the rail at toddler height, the drawer at toddler height, and the top of the wardrobe at adult-reach height for stuff the kid shouldn't touch.
At the foot of a bed. A long, low wardrobe (think 1.8 to 2.4 m wide and 90 cm tall) at the foot of the bed acts as a low chest. Hanging takes the back half, drawers take the front. You can sit on it to put socks on.
In a hallway. Coats are short. A 1.2 m tall wardrobe with two doors, hanging rail behind one, three deep drawers behind the other, eats a hallway wall and gives you somewhere to put gloves.
The place they don't earn their keep is a normal bedroom with full-height ceilings. There you're just throwing away a metre of vertical storage for no reason.
What goes inside
The internal layout is the whole game. You've only got 90 cm to 1.3 m of vertical to play with, so the choice is binary on most rows.
Hanging rail height: shirts and jackets need 90 cm of clear drop below the rail, so the rail sits at the top of the cabinet minus about 5 cm for the bracket. That leaves nothing above the rail for a top shelf inside the wardrobe. The top shelf goes on top of the wardrobe, not in it.
Drawers: standard internal drawer depths are 10 cm (for socks and small things), 15 cm (for folded T-shirts and underwear), and 20 cm (for jumpers). A half height wardrobe with three drawers usually wants 15-15-20 cm from top to bottom. Soft-close runners add 2.5 cm to the front-to-back you need internally, so check the depth.
Plinth: 8 to 12 cm at the bottom is the convention. Skip it if the wardrobe sits on a thick rug or if you want the line to run flush to the skirting board. The plinth is also where you can hide an LED strip if that's a thing you want, which it usually isn't, but I won't tell anyone.
Measuring it correctly
The tape measure is where most people fail. Three things, in order.
Width at three heights: floor, mid-height (about 50 cm up), and at the top of the planned wardrobe. Walls aren't square. The difference between the widest and narrowest reading on a 1.8 m span in an old apartment can be 1.5 cm. You build to the narrowest minus 5 mm for fitting.
Ceiling height at the back wall, measured at the centre of where the wardrobe will go and at both ends. Sloped ceilings usually slope. If the difference between the two ends is more than 3 cm over the wardrobe's width, you'll need a top that's cut on a matching angle, not a flat top.
Floor flatness. Lay a long spirit level along the wall. If the floor falls away by more than 5 mm over the wardrobe's width, build adjustable feet into the plinth. A wardrobe that rocks because the floor isn't flat will misalign its doors within six months.
Off-the-shelf vs. measured-to-fit
The off-the-shelf market for half height wardrobes is thin. IKEA sells the PAX in 2.01 m and 2.36 m heights and that's roughly it; most other big-brand wardrobes are also full-height. There's a small market for kids' wardrobes around 1.2 m and for sideboards that get pressed into wardrobe duty, but neither of those is built for hanging clothes for years.
The next step up is fitted-furniture brands (Sharps, Hammonds, Neville Johnson in the UK, equivalent local players elsewhere) who'll build a half height unit. Quotes I've seen range from 1,800 to 4,500 euros for a single-bay half-height in MFC, more for ply or veneered carcasses. Lead time is four to ten weeks.
The third path, which is what Marieke went with, is to buy the panels pre-cut to your dimensions, in birch ply or melamine, and assemble them yourself with cam locks and dowels. A 1.84 m by 1.08 m by 60 cm carcass plus two doors and four drawer fronts in 18 mm birch ply landed at around 720 euros and went together in an afternoon. The drawer runners and hinges added another 90.
If you're squinting at a sloped ceiling and trying to figure out how to get shirts hanging where the catalogue won't help, that's the kind of thing knuslabs.com was built for.
