Frequently asked questions
How much rail space does a hanging garment actually take up?
On average, around 2-4cm per garment on the rail, depending on how bulky the item is — a thin shirt takes up much less space than a padded coat. This calculator uses a blended average across typical wardrobe contents.
Is it better to hang or fold clothes to save space?
Hanging works well for anything prone to creasing (shirts, dresses, jackets) and keeps them ready to wear, while folding into drawers or shelves is more space-efficient for jumpers, t-shirts and other everyday basics.
Should I size a wardrobe for my current clothes or leave room to grow?
It's generally worth adding some headroom (10-20%) beyond your current garment count, since wardrobes tend to fill up over time and a slightly under-sized wardrobe becomes cramped and hard to keep organised.
Do sliding door wardrobes offer less usable space than hinged doors?
Sliding door wardrobes can save floor space since the doors don't swing open, but they sometimes have a slightly narrower usable interior due to the internal door track — check the manufacturer's internal rail length rather than just the external width.
How this calculator works
The calculator asks for the number of garments you need to hang and multiplies that by an average of 3cm per garment. This average blends shirts, trousers on hangers, dresses, and bulkier items like coats — a thin shirt might take 2cm, while a padded winter coat could take 4-5cm. The result is the total rail length you need in centimetres. The calculator then matches this to a standard wardrobe size: single (~70cm rail), 1.5-door (~100cm), double (~140cm), or triple (~210cm).
These are rail-length estimates only — most wardrobes also have shelves, drawers and sometimes a shoe rack at the bottom for folded clothes, shoes and accessories. If you have a lot of folded clothes, jumpers or t-shirts, you'll want shelves as well as hanging rail. A good rule of thumb is to have roughly equal amounts of hanging and folded storage if you mix both types.
Wardrobe sizes and garment capacity
| Wardrobe type | Rail length | Garments (approx) | Width | Best for |
|---|---|---|---|---|
| Single | ~70cm | 20-25 items | 50-60cm | Small bedroom, ensuite, single person |
| 1.5-door | ~100cm | 30-35 items | 80-100cm | Standard bedroom, couple |
| Double | ~140cm | 45-50 items | 120-150cm | Master bedroom, couple |
| Triple | ~210cm | 70-75 items | 180-220cm | Large bedroom, family |
Worked example: A wardrobe for 40 garments
For 40 garments, the calculator estimates 40 × 3 = 120cm of hanging rail needed. This fits a double wardrobe (~140cm rail) with some room to spare, or a 1.5-door wardrobe (~100cm rail) if you're willing to squeeze items closely together. The double wardrobe is the better choice — it gives you space to add more clothes over time without the wardrobe feeling cramped.
If you also have 20 jumpers and t-shirts that you prefer to fold, you'd want a wardrobe with at least 2-3 shelves in addition to the hanging rail. A double wardrobe with a rail on one side and shelves on the other gives the best of both worlds. If you have lots of shoes, look for a wardrobe with a shoe rack at the bottom or a separate shoe storage unit.
Common mistakes when choosing a wardrobe
- Sizing the wardrobe for current clothes only. Wardrobes tend to fill up over time — you'll buy more clothes, your style might change, or you might share the wardrobe with a partner. Add 10-20% extra rail length beyond what you currently need to avoid outgrowing it in a year or two.
- Forgetting to account for the door swing. A hinged door wardrobe needs clearance in front to open fully — typically 60-90cm depending on the hinge type. If the wardrobe is next to a bed, make sure the door can open without hitting the bed or a bedside table. Sliding door wardrobes don't need front clearance, but they need a bit more width for the door tracks.
- Ignoring the bedroom's proportions. A triple wardrobe (180-220cm wide) dominates a small bedroom and can make the space feel cramped. In a room under 12m², a double wardrobe is usually the maximum that looks proportional. If you need more storage, consider a built-in or fitted wardrobe that uses the full wall height and depth, or add a separate chest of drawers.
- Not checking the internal dimensions. The external width of a wardrobe includes the frame and door thickness, so a '180cm' wardrobe might have only 160cm of usable internal rail length. Always check the manufacturer's specifications for the actual rail length and shelf space, not just the external dimensions.
What to look for when buying a wardrobe
Wardrobe type affects both storage capacity and room layout. A freestanding wardrobe is the easiest to install and can be moved if you rearrange the room, but it takes up floor space and the doors swing into the room. A built-in or fitted wardrobe is made to measure for the wall, giving you maximum storage and a seamless look, but it's more expensive and can't be moved. A sliding door wardrobe saves floor space and works well in narrow rooms, but the internal rail length is often shorter than a hinged door wardrobe of the same external width.
Internal configuration determines how usable the space is. A wardrobe with a combination of hanging rail (for shirts, dresses, coats) and shelves/drawers (for folded clothes, shoes, accessories) is more versatile than one with only hanging space. Adjustable shelves let you reconfigure the interior as your needs change. A pull-out trouser rail or a tie rack can add organisation, but they reduce the main hanging space. Think about what you actually store before choosing a configuration.
Finally, think about the finish and material. MDF or wood veneer wardrobes are affordable and come in a wide range of finishes, but they need a moisture-resistant coating in a damp bedroom. Solid wood wardrobes are more durable and can be refinished, but they're heavier and more expensive. Aluminium or metal wardrobes are modern and lightweight, but they can feel cold and clinical. For most UK bedrooms, a well-finished MDF or veneer wardrobe with a 10-year guarantee is the best balance of cost and quality.

What's the difference between a freestanding and a built-in wardrobe?
A freestanding wardrobe is ready-made, easy to install and can be moved, but it takes up floor space and the doors swing into the room. A built-in wardrobe is made to measure for the wall, giving you maximum storage and a seamless look, but it's more expensive, requires professional installation, and can't be moved. For a rental property or a room you might rearrange, a freestanding wardrobe is more flexible.
How deep should a wardrobe be?
Standard wardrobes are typically 60cm deep, which is enough for most clothes on hangers. A shallower wardrobe (50-55cm) can work in a very narrow room, but it might not fit bulky coats or dresses on hangers comfortably. A deeper wardrobe (70cm+) gives more room for shelves and drawers, but it can dominate a small bedroom. Measure the available depth in your room before buying.
Should I get a wardrobe with mirrors on the doors?
A mirrored wardrobe door can make a small bedroom feel larger by reflecting light and creating the illusion of more space, and it saves you from having a separate full-length mirror. However, mirrored doors can be heavy, more expensive, and they show fingerprints and smudges more than a standard finish. If you have a small, dark bedroom, a mirrored wardrobe is worth considering. If you have plenty of light and space, a standard finish is usually fine.
How do I organise a wardrobe efficiently?
Use a combination of hanging space, shelves and drawers. Hang items that crease easily (shirts, dresses, jackets) on the rail. Use shelves for folded jumpers, t-shirts and jeans — fold them vertically (like in a shop) so you can see everything at once. Use drawers for underwear, socks and accessories. A pull-out trouser rail or a tie rack can add organisation, but only if you actually use them. The simplest system is often the best — if you have to spend 10 minutes finding a shirt every morning, the organisation isn't working.
