Quick answer: In a small room, go tall and shallow rather than low and deep - height uses wall space you were not using, while depth eats the floor you are. Match the baskets to each other and to the wall colour so the unit reads as one object rather than a grid of containers.
In a compact flat a storage unit is the largest single object you will add to a room, so it is worth getting right.
Tall and shallow beats low and deep
The most useful rule when floor space is the constraint.
A low wide unit consumes floor, which is the thing a small room has least of. A tall narrow one uses wall, which is free, and it draws the eye upward, which makes a room feel taller.
Depth is the dimension to be strict about. A 30cm-deep unit against a wall barely intrudes; a 45cm one changes how you move through a small room.
Fix tall units to the wall following the manufacturer's instructions, particularly with children about.
Match the unit to the wall
A small room feels bigger when large objects recede.
A white unit against a white wall almost disappears. The same unit in dark oak becomes a feature, which is fine if you want one and unhelpful if you wanted the room to feel larger.
The same goes for the baskets. Choosing them close to both the unit and the wall makes the whole thing read as one quiet object - the matching guide covers picking a colour.
The baskets matter more than the frame
People choose the unit carefully and then buy whatever baskets fit.
That is backwards. The frame is mostly hidden once loaded; the baskets are what you actually see. A cheap unit with matching baskets looks better than an expensive one with a mismatched set.
Buy them as a set, in one colour, and fill about two thirds of the openings - the cube shelving guide covers measuring and fitting.
Leave some openings empty
Especially in a small room, where a fully loaded unit reads as a wall of storage and makes the space feel tighter.
Books, a plant, a lamp, or simply nothing. The gaps give the eye somewhere to rest and stop the unit dominating - the styling guide covers the proportion.
Use it as a divider
A trick that suits studio flats and open-plan rooms.
An open-backed unit placed at right angles to a wall separates a sleeping area from a living one without building anything, and gives you storage from both sides.
Two conditions: keep it low enough to see over, or both halves feel like corridors. And use baskets that look finished from behind, because the back is visible from the other side.
Weight low, light high
Practical and safety-related.
Heavy things in the bottom row keeps a tall unit stable and makes it easier to load. Light, rarely used things at the top, labelled since you cannot see in from below.
In a child's room, put anything they need in the bottom row so they can reach it - the children's guide covers reach by age.
What to put in it
Storage units suit soft and small things: textiles, toys, craft supplies, paperwork, cables, shoes.
They suit books well too, but books go on the open shelves rather than in baskets, since a soft basket full of books slumps and you cannot see spines.
Avoid anything you need daily on a high shelf, and anything heavy in a fabric basket - the materials guide covers what holds weight.
The top surface
Every unit has one, and it attracts clutter within a fortnight.
Decide what it is for before it decides for itself. A lamp and a plant reads as deliberate; nine assorted objects reads as another surface you now have to tidy.
In a small room, a mostly clear top is worth more than the storage it could hold.
Buying secondhand
Storage units are one of the best things to buy used, because they are bulky to ship and people replace them when they move.
Check the shelves are not bowed and that the back panel is intact, since that is what stops the frame racking. Then buy new baskets to match, which is the part that makes it look considered.
Assembly and levelling
Two practical points that affect how the finished thing looks.
Flat-pack units rack easily if the back panel is fitted loosely, and a racked unit means the openings are no longer square, so baskets sit crooked however well they fit. Fit the back panel properly and square the frame before nailing it.
Then check the unit is level. On an uneven floor a tall unit leans, which is visible against a wall line and makes every basket look wrong - the matching guide covers how much alignment matters.
Buying baskets before the unit
Tempting when you see a set you like, and usually a mistake.
Units vary by a centimetre or two even when they look identical, so baskets bought first constrain which unit you can buy. Buy the unit, measure the actual openings, then buy baskets to suit.
The exception is if you already own the baskets, in which case take the measurement with you - the cube shelving guide covers what to measure.
If you are buying the unit and the baskets together, start with storage units with baskets, then fill them from shelf and cube storage. The room-by-room guide has more on small rooms.
The short version
- Tall and shallow uses free wall space; low and deep eats the floor you need.
- Match the unit and baskets to the wall so the whole thing recedes.
- The baskets matter more than the frame, because the frame disappears once loaded.
- Fill about two thirds of the openings and leave the rest for books or nothing.
- Weight low and light high - and fix tall units to the wall as the maker instructs.
Frequently asked questions
What shape storage unit suits a small room?
Tall and shallow. Height uses wall space you were not using and draws the eye upward, while depth eats the floor a small room has least of. A 30cm-deep unit barely intrudes where a 45cm one changes how you move.
What colour should a storage unit be in a small room?
Close to the wall, so it recedes. A white unit against a white wall almost disappears, while the same unit in dark oak becomes a feature - fine if you want one, unhelpful if you wanted the room to feel bigger.
Do the baskets or the unit matter more?
The baskets. The frame is mostly hidden once the unit is loaded, so a cheap unit with matching baskets looks considerably better than an expensive one with a mismatched set bought piecemeal.
Can a storage unit divide a room?
Yes, and it suits studios and open-plan spaces. Use an open-backed unit at right angles to a wall, keep it low enough to see over so neither half feels like a corridor, and use baskets that look finished from behind.
Where should heavy items go in a storage unit?
The bottom row, which keeps a tall unit stable and makes loading easier. Put light, rarely used things at the top and label them, since you cannot see into a high basket from below.
