Measure the room and access route
1. Measuring only once or in one place
Walls, floors and ceilings are not always square. Measure width and height at several positions, record the smallest usable dimension and include skirting, coving, sockets and protruding handles. Use millimetres to reduce ambiguity, but take the installation tolerance from the product or fitter rather than applying a universal allowance.
2. Forgetting delivery, assembly and door movement
A wardrobe can fit the wall but fail to reach the room. Check packaging dimensions, stairs, landings, doorways and turns. Mark the assembled footprint and the actual hinged-door arc or sliding-door standing space on the floor.

Follow our full guide to choosing the right wardrobe size before finalising an order.
Judge construction and finish properly
3. Choosing by material name alone
MDF, particleboard, plywood and timber vary by grade, thickness and finish. Inspect edge sealing, back-panel design, rail support, hardware and spare-part availability. A well-designed engineered-board wardrobe can be more suitable than a poorly constructed product with a premium-sounding label.
4. Ignoring cleaning, sunlight and moisture
Gloss may show fingerprints, matt can mark if scrubbed aggressively, and real veneer needs care at edges and joins. Persistent condensation can damage the core beneath any finish. Read the care sheet and correct known damp before installing furniture.

Design the interior around real belongings
5. Buying a generic interior without counting clothes
Count long and short hanging garments, folded items, shoes, drawers and bedding. Double hanging is efficient for shorter clothes, but coats and dresses need full height. With sliding doors, make sure drawers and frequently used sections remain accessible behind the panel overlap.
More shelves are not automatically better. Deep fixed shelves can hide items at the back, while too little rail space forces crease-prone clothing into piles.
Keep the wardrobe in proportion to the room
6. Maximising storage until circulation disappears
The largest unit that fits the wall may still make the bedroom awkward. Tape the footprint on the floor, place the bed and other furniture, then walk the everyday route. Check that doors and drawers open and that a person can stand comfortably while using the wardrobe.
7. Blocking light, heat or a safe route
Do not cover a radiator, ventilation opening, window or route to the bedroom door. A tall dark wardrobe directly opposite the entrance can also dominate the sightline. Functional access and safety take priority over using every centimetre of wall.

Plan assembly and installation before checkout
8. Underestimating assembly difficulty
Large panels, mirrors and sliding doors may need more than one person, sufficient floor area and specific tools. Check whether the unit is built flat or upright, whether assembly is included and who handles packaging disposal. Use competent installers for work beyond your ability.
9. Treating wall restraint and load limits as optional
Follow the supplied wall-restraint instructions using fixings appropriate to the wall construction, after checking for hidden services. Do not overload shelves or rails beyond the product specification, and never let children climb on doors, drawers or shelving.
Think beyond the first room layout
10. Ignoring future needs and moves
Fitted wardrobes maximise a particular space but normally remain with the property. Freestanding and modular units offer more flexibility, although repeated disassembly can weaken some flat-pack fixings. Consider expected moves, changing clothing needs and whether replacement shelves, doors or hardware will be available.
Use a final buying checklist
- Room measurements checked at several points.
- Delivery route and assembly method confirmed.
- Door movement and walkway tested on the floor.
- Interior matched to actual belongings.
- Material, finish and care instructions understood.
- Window, heat and ventilation kept clear.
- Wall restraint and load limits confirmed.
- Spare parts, returns and warranty terms reviewed.
Once all eight checks are complete, compare all wardrobes by fit and function before narrowing the choice by colour or style.
Pre-checkout wardrobe decision table
| Decision | Evidence to collect | Common failure | Pass condition |
|---|---|---|---|
| Will it reach and fit the room? | Room, packaging, doorway, stair and turning measurements | The unit fits the wall but cannot be delivered or raised | Route, footprint and assembly orientation are confirmed |
| Will the doors and interior work? | Door movement, overlap diagram and clothing count | Doors hit furniture or drawers sit behind an overlap | Everyday storage remains comfortably accessible |
| Will the construction suit the room? | Core, edges, back, hardware, care sheet and moisture context | A material label hides weak details or unsuitable care | The complete specification matches the use and conditions |
| Can it be installed safely? | Manual, wall type, fixing requirements and installer scope | Restraint or complex panels are treated as an afterthought | Responsibilities, tools and competent help are arranged |
Frequently asked questions
How much fitting tolerance should I leave?
Use the clearance stated for the product or by the fitter. There is no universal allowance because freestanding, recessed, flat-built and upright-assembled wardrobes have different requirements.
Is the biggest wardrobe that fits the best value?
Not if it removes comfortable circulation, blocks an opening or contains storage you cannot access. The best value is usable capacity that suits the room and belongings.
Can I judge quality from MDF, particleboard or timber alone?
No. Grade, panel thickness, edge protection, back construction, rail support, hardware and spare-part availability all affect performance. Assess the complete build.
Should wall restraint be decided after delivery?
No. Read the instructions first, identify the wall construction and hidden-service risk, and confirm who will provide suitable fixings and competent installation before ordering.
