Small Bedroom Design Ideas: 864 Litres Above Your Wardrobe, and the Low Bed That Kills Your Storage

Most small bedroom design ideas lists contradict themselves twice before they finish. This one tells you low beds with simple lines are ideal for small spaces, that a bed height should not exceed 60cm, and that low-profile beds create a more spacious feel then, three lines later, to choose a bed with storage and put extra towels and clothes under it.

In Australia those two instructions cancel out, and the arithmetic below shows exactly where. It also shows where the real space is hiding, which is not on the floor at all. The bedroom designs and ideas that survive contact with a tape measure are a short list, and maximising a small bedroom requires smart layout planning before it requires a single purchase.

The 864 litres above your wardrobe

Vertical storage draws the eye upward and maximises storage, vertical storage utilisation helps create an illusion of openness, and built-in storage maximises space in small bedrooms. All true, and almost nobody does it, because of a mismatch between two Australian standards nobody thinks about together.

Bunnings sells sliding wardrobe doors in exactly two heights: 2,100mm and 2,400mm. Hume’s hinged robe doors come in 2,040mm and 2,340mm. Meanwhile, the National Construction Code sets a habitable room ceiling at 2.4m, most new Australian homes now build at 2.55m or 2.7m, and the NSW Apartment Design Guide requires 2.7m ceilings in apartments where no stock robe door reaches within 300mm of the ceiling.

Take a common case: a 2,400mm-wide robe, 600mm deep, topped out at 2,100mm, under a 2.7m ceiling.

2.4 x 0.6 x 0.6 = 0.864m³ 864 litres of storage you paid for the floor space of and did not build.

A word on what 864 litres holds, because this is where most articles overclaim. By volume it is sixteen archive boxes; by geometry, once you allow for the gaps between rigid boxes, six fit about 36% packing efficiency. Which is the argument for purpose-built shelving rather than a stack of tubs, since shelves at the right pitch recover most of that 64%. Australian joiners charge roughly $750–$3,125 a linear metre, and no supplier publishes a premium for going to the ceiling to ask for it inside the quote, not as an extra.

The same logic runs down the rest of the room: wall-mounted shelves can save floor space in small rooms, shelving above the bed creates additional storage, and building shelves above the bed creates additional storage space.

Rails, robes and drawers

Open hanging rails can replace bulky wardrobes, says the brief, twice open hanging rails can replace bulky wardrobes in small bedrooms. Test it in depth. An Australian built-in robe is 600mm deep, and one NSW wardrobe maker calls 600mm “the minimum for storing adult clothing on hangers.” A Kmart rail is 400–430mm deep, rated to 10kg, at $12 to $99. So a rail saves about 180mm of depth by giving up the depth a manufacturer says you need, and the retailer concedes the dust. Good in a rental, poor in a house you own.

A chest of drawers provides extra storage and personalisation options, and it is the piece most small bedrooms should buy first. The drawers hold what the robe cannot and the top becomes display space. Multi-functional furniture saves space in small bedrooms more reliably than clever gadgets: an ottoman at the foot of the bed, bedside tables with a drawer rather than an open shelf. And yes, choose a bed with storage for small bedrooms provided you read the next section first.

The low bed and the storage bed cancel out

Now the contradiction. The brief says a bed height should not exceed 60cm in small rooms, and I could not find one Australian source linking bed height to room size. Every Australian figure is ergonomic, not spatial: retailers put the comfortable range at 550–650mm floor-to-mattress-top, pushing to 650–700mm for adults over 185cm, and the only Australian numeric health guidance from an NDIS-registered supplier puts it at 450–550mm, mattress top at the lower edge of your thigh, knees at 90°.

So 600mm is not a low bed in Australia. It is a normal one.

What fits underneath

Here is why that matters more than the aesthetics. Storage under the bed can hold extra towels and clothes, and a bed with hidden storage serves dual purposes but every under-bed storage box sold in Australia is 160–190mm tall. Kmart’s 40-litre tub is 180mm, Howards’ 52-litre is 160mm, IKEA’s SKUBB is 190mm. You need about 210mm of clearance for any of them to slide.

Drop your bed to a fashionable 400mm and you have roughly 100mm underneath. On paper that costs you around 342 litres. In practice it costs you 100%, because nothing sold in this country fits. Eight Kmart tubs under a queen is 320 litres for $112 the cheapest storage in the house, and a low bed forfeits all of it.

Melbourne designer Chris Carroll argues the other way and is worth hearing: he warns off storage beds in small rooms because gas-lift and drawer bases are “notoriously high”, keeping frame plus mattress near 600mm. Both positions are defensible; following both is not.

The honest rule: pick your bed frame height for your knees, not for the photograph, then decide whether the space under it is storage or nothing and if it is storage, buy the boxes before the bed.

Fixing things to a wall in an Australian house

Shelving above the bed is a lovely idea and a genuinely risky one if you get the fixing wrong. A typical Bunnings floating shelf is rated 5kg into plasterboard and 10kg into masonry, with the explicit instruction to ensure at least one screw hits a stud. An Australian framing supplier’s line about anything above a sleeping head is the one to remember: use mechanical fixings, not just adhesive.

Find the stud. If you cannot, put the shelf somewhere other than above the pillow.

Floating furniture, and what it is worth

Floating furniture creates an uninterrupted line of sight across the floor, and the effect is real because the eye reads continuous floor as more floor. It is also measurable: a wall-hung bedside table frees 0.1824m² per side, so a pair recovers 0.3648m² just over 4% of a 9m² bedroom with the same caveat about the 5kg rating and the stud.

Wall-mounted lighting frees up surface space, which on a 350mm bedside table is the difference between a lamp and somewhere to put your book. Mount it around 450mm above pillow height. One hard Australian limit: anything hardwired is a licensed electrician’s job. Queensland’s Electrical Safety Office penalties for DIY electrical work run to $40,000, and to $600,000 and five years’ imprisonment where someone is exposed to a risk of death. Plug-in and rechargeable sconces are the compliant route for a renter, and there are good ones.

Strategic placement of mirrors can expand visual depth, using mirrors can create a sense of infinite space, and mirrors can bounce light and make rooms feel larger provided they reflect a window or a doorway rather than a wall. No Australian source publishes mirror placement guidance, so treat the rules of thumb as exactly that. On value, a Kmart 1,700 x 500mm leaner is about $76 per square metre of reflection against roughly $150 for a designer equivalent: one place where cheap works.

Curtains: hang them high, and know what it costs

Hanging curtains near the ceiling creates an illusion of greater height, and minimalist window treatments can enhance the illusion of taller walls. Both hold. Australian window furnishing suppliers put the track 150mm above the frame and extend it 150–300mm each side as standard; going to the ceiling in a 2.7m room adds about 440mm of drop, or roughly 20% more fabric so the trick is real but it is not free.

There is a performance angle too. YourHome, the Australian Government’s guide, puts it plainly: “Up to 40% of a home’s heating energy can be lost and up to 87% of its heat gained through windows.” A pelmet traps still air behind a curtain; a ceiling-fixed, wall-to-wall track closes the same gap without eating visual height. The failure mode is the common one, a track 150mm above the frame, no pelmet, warm air rolling down the glass all night. For renters, honeycomb blinds are rated around R0.979 against roughly R0.35 for double glazing.

While you are there, check the window does its legal job: the NCC requires glazing of at least 10% of floor area and openable ventilation of at least 5%. In a 9m² bedroom that is 0.90m² of glass and 0.45m² that opens and a sliding window opens only half its area, so a 0.90m² slider sits exactly at the limit.

Colour, pattern and the white myth

Light and neutral palettes can create an open atmosphere, natural tones create a calm atmosphere in small bedrooms, and cohesive colour palettes reduce visual choppiness in small rooms. The last of those is the one every Australian source agrees on: hold the room to two or three colours and the choppiness disappears by itself.

On white, Australia is genuinely split, and the split runs by source type rather than by argument. Paint brands and retailers say light; independent Australian designers increasingly say the opposite, because a small bedroom is the one room you are in at night with the lamps on. Notably, no Australian source I found says a dark small bedroom is a mistake. So opt for whichever you will enjoy and stop treating white as the safe default. The same disagreement covers the ceiling: drench it to match the walls and the room reads as one volume, keep it lighter and the walls read taller. Pick one and commit.

Wallpaper and pattern scale

One claim to set aside. Using one wallpaper pattern can create a sense of infinite space, says the brief but no Australian source supports it, and the one Australian supplier with detailed guidance contradicts itself on whether large or small patterns suit a small room. Both its pages agree on vertical emphasis and one feature wall rather than four. Follow that much.

Choose one focal point to avoid overwhelming a small bedroom, the bed, the window, or one piece of art, not all three and use simple headboard designs to avoid visual clutter. Textured layers can add comfort without adding clutter, which is where natural materials earn their place: linen, timber, wool, a jute rug. Texture is the way you get warmth and a welcoming, relaxing feel without adding objects, and it is what stops a disciplined room reading as boring.

Australian display homes make the room feel larger by subtraction, not trickery. One builder says plainly that they avoid overcrowding with furniture or decor and scale everything to the room. It is why the products featured in a display bedroom are always fewer than you expect, and a guest bedroom can go further still, since nobody keeps clothes in it.

Bedding, and where the cushion habit stops

Keep bedding simple to prevent a cluttered look in small rooms, and limit bedding to avoid a cluttered appearance in small spaces. There is a nice Australian illustration of this: the same Melbourne stylist who prescribes a bare minimum of three cushions plus two Euros on a normal queen strips a small bedroom back to pillows and a single throw. The small bedroom is where Australia’s cushion default stops.

For linens, buy by season rather than by trend: Australian makers grade quilts around 150–225 gsm for summer, 300–400 for mid-season and 450–500 for winter. The price ladder here runs from a $49 Kmart queen quilt cover to about $450 for Australian French flax linen, and the middle of it is where most people should sit. Look for GOTS or OEKO-TEX if fibre matters to you and know that an Australian Made logo certifies where the last substantial transformation happened, not who owns the company or where the fibre grew.

Is it actually a bedroom?

Worth knowing before you buy anything. The NCC sets no minimum floor area for a bedroom and the “6.5m² minimum” figure circulating on Australian property sites appears nowhere in the code, so forget it. What does exist: the NSW Apartment Design Guide requires that “master bedrooms have a minimum area of 10m2 and other bedrooms 9m2 (excluding wardrobe space)” with a 3m minimum dimension, in apartments.

A windowless room cannot comply as a habitable room on the standard pathway though a skylight at 3% of floor area satisfies the light requirement. And there is no Australian rule defining what an agent may advertise as a bedroom: no REIA standard, no valuation body definition, no requirement for a built-in wardrobe. The only control is the misleading-conduct provision of the Australian Consumer Law. If you are wondering whether the third bedroom in a listing is really a bedroom, the answer is that nobody has promised you it is.

It does matter financially: Australian median price data across eight suburbs puts the gap between two and three bedrooms at 10% to 83%, depending entirely on the market.

What it costs

Painting a small bedroom in Australia runs a median $920, or roughly $10–$30 per square metre, against about 3.2 litres of wall paint and 1.2 litres of ceiling paint if you do it yourself in a 3 x 3m room. A built-in robe is $1,110–$3,010 per linear metre, median $2,060 the same money a small bathroom refresh costs, and it will change your life more.

Three realistic tiers: a refresh with paint, linens and a couple of new elements at $250–$400; a mid update with bedding, a light, a mirror and storage at $1,950–$2,600; and a full redo with built-in joinery at $7,500–$9,500.

The short version

Look up before you look around. The 864 litres above a standard robe is the cheapest storage in the house and the only square metres in a small bedroom that are not already spoken for. Decide the bed height on ergonomics, then commit either it is high enough for boxes to slide under or it is not, and both answers are fine as long as you are honest about which one you chose.

After that it is the easy part: one focal point, two or three colours, curtains to the ceiling, a mirror opposite the window, and a bed you do not have to walk sideways past. Explore whatever style you like modern, contemporary, a deep blue master bedroom, a pale guest room because the geometry underneath is the same, and the numbers will prove which ideas survive on your site and which were only ever an amazing photograph.

A small bedroom that is calm, airy and practical is not a design problem but a subtraction problem. That is the whole story, and the fun part, of course, is deciding what you can live without. Find one example you love, decorate around the single sign of it that fits, and discover how much bigger a room gets when there is less in it, the most reliable inspiration going, and the one thing interior designers never disagree about.
