Choosing the right wardrobe size is one of those decisions that seems simple until you actually start measuring your bedroom wall. A few centimetres either way can mean the difference between a wardrobe that fits neatly into your room and one that feels like it is fighting for space. If you have been searching for a sliding door wardrobe 100cm wide, you are likely dealing with exactly this kind of space puzzle, whether that is a box room, a guest bedroom, or a flat where every inch of floor space genuinely matters.
This guide walks through everything worth knowing before you buy, from what fits inside a wardrobe this size to how it compares with other popular widths, so you can make a confident decision rather than a guess.
Why Choose a 100cm Wide Wardrobe With Sliding Doors?
A 100 cm wide wardrobe with sliding doors sits in a useful middle ground. It is wide enough to offer genuine, practical storage, yet compact enough to slot into rooms where a larger wardrobe simply would not work. This makes it a popular choice for several common bedroom situations across the UK.
Smaller bedrooms and box rooms benefit the most, since every wall is often already accounted for by a bed, a chest of drawers, or a desk. Guest bedrooms are another strong fit, where storage needs are lighter and a smaller wardrobe avoids wasting space that could be used elsewhere. Flats and apartments, particularly in cities where square footage comes at a premium, also lean toward this size for the same reason.
The sliding door mechanism itself adds a further practical benefit. Because the doors glide along a track rather than swinging outward, you do not need to leave extra floor clearance in front of the wardrobe. This is particularly useful if a bed or piece of furniture sits close by, since a hinged door in that same spot would constantly bump or catch.
What Storage Does a 100cm Sliding Door Wardrobe Actually Offer?
It helps to know exactly what you are getting before you commit to a size. Most wardrobes in this range follow a fairly consistent internal layout, designed to make the most of a compact footprint.
| Feature | Typical Specification |
| Hanging rails | One to two rails, depending on the model |
| Shelving | Three to five shelves for folded items |
| Door type | Two sliding doors, often one mirrored |
| Suitable for | One person’s everyday wardrobe |
| Common finishes | Mirrored, matte white, black, or artisan wood effect |
A typical 100cm wide sliding door wardrobe offers one side with a hanging rail for clothes on hangers, and the other side fitted with shelves suited to folded jumpers, t-shirts, or accessories. This split layout tends to work well for a single person’s day to day wardrobe, though it will run out of room quickly if you are trying to store bedding, coats, and seasonal items in the same unit.
Mirrored doors are a particularly popular option at this width. Beyond the obvious benefit of a built in mirror, the reflective surface helps bounce light around a smaller room, which can make a compact bedroom feel noticeably brighter and more open. Furniture Island’s 100cm sliding door wardrobe collection includes several mirrored options designed specifically with smaller rooms in mind, alongside matte and wood effect finishes for those who prefer a different look.
Expert Tip: Measure More Than Just the Wall
Before ordering, measure the full width of the wall, but do not stop there. Check the ceiling height too, since some sliding wardrobes need a small gap above for the door track. Look at where any radiators, skirting boards, or sockets sit, as these can sometimes interfere with a flush fit against the wall. It is also worth measuring the depth available, since most sliding wardrobes in this width sit somewhere between 55cm and 65cm deep, which needs to be accounted for alongside the width.
How Does 100cm Compare to Other Popular Wardrobe Widths?
Width is the single biggest factor separating one wardrobe from another, so it helps to see how the 100cm option stacks up against its closest alternatives.
| Width | Best Suited For | Typical Storage |
| 100cm | Box rooms, guest rooms, single occupant | One hanging rail, a few shelves |
| 120cm | Small to medium bedrooms | Slightly wider hanging space and shelving |
| 150cm | Main bedrooms, single or shared use | Two distinct sections, more shelving |
| 180cm+ | Larger bedrooms, shared wardrobes | Full hanging sections plus drawers |
If your room can comfortably accommodate a little more width, it is worth comparing against a sliding wardrobe 150cm wide, since the jump from 100cm to 150cm often brings a noticeably larger increase in usable storage than the width difference alone might suggest. Furniture Island’s 150cm sliding door wardrobe range, for example, typically includes a fuller hanging section alongside additional shelving, making it a better fit for anyone storing more than a single, modest wardrobe of clothing.
For those after a true middle ground, the 120cm sliding door wardrobe collection offers a touch more room than the 100cm option without requiring the wall space a 150cm model demands. The right choice ultimately depends on how much you genuinely need to store, not just how much wall space you have to fill.
Mirrored or Plain Doors: Which Should You Choose?
This comes down largely to personal taste, though there are a few practical points worth weighing up. Mirrored doors tend to suit smaller, darker rooms particularly well, since they reflect available light and create a sense of extra space. They also remove the need for a separate full length mirror elsewhere in the room, which can be a useful space saving bonus in a compact bedroom.
Plain or matte finishes, on the other hand, tend to suit rooms with a more minimal or muted decor style, where a large reflective surface might feel like too much visual noise. They also tend to show fewer fingerprints and smudges day to day compared with a mirrored panel.
Furniture Island’s mirrored wardrobe range covers both styles across various widths, so it is worth browsing a few finishes side by side before settling on one, particularly if you are still deciding how the wardrobe will sit alongside your existing furniture.
Sliding vs Hinged: Does the Door Type Matter at This Width?
At 100cm, the case for sliding doors is particularly strong. Hinged doors at this width need clearance to swing open, which can be genuinely difficult to manage in a smaller room where the wardrobe sits close to a bed or another piece of furniture. Sliding doors remove this issue entirely, since the door simply moves along its track rather than out into the room.
The trade off is that you can only access one section of the wardrobe at a time, since the door covering it needs to be slid across before the other side becomes available. For most single occupant bedrooms, this is a minor inconvenience rather than a genuine drawback, but it is worth being aware of if you are used to a hinged wardrobe where both sides are visible and accessible simultaneously.
Frequently Asked Questions
Is a 100cm sliding door wardrobe big enough for one person?
In most cases, yes. A wardrobe of this width typically includes one hanging rail and a handful of shelves, which comfortably covers everyday clothing for a single person. If you also need to store bedding, coats, or seasonal items in the same unit, you may find the space runs out faster than expected.
What is the difference between a 100cm wardrobe sliding doors model and a 150cm wide sliding door wardrobe?
The main difference is internal capacity. A 150cm model typically includes a fuller hanging section along with additional shelving, making it a better fit for households needing more storage or for a main bedroom used daily by one or two people, while the 100cm option suits lighter, more modest storage needs.
Do sliding doors really save space compared to hinged doors?
Yes. Since sliding doors move sideways along a track rather than swinging outward, you do not need to leave extra floor clearance in front of the wardrobe. This makes them especially practical in smaller bedrooms where a hinged door would otherwise be obstructed by a bed or other furniture.
Can a 100cm wardrobe fit in a very small box room?
Often, yes, though it is essential to measure the full wall space first, including ceiling height and any nearby radiators, sockets, or skirting boards that could interfere with a flush fit. Most 100cm sliding wardrobes are specifically designed with smaller rooms in mind.
Should I choose a mirrored or plain finish for a small bedroom?
Mirrored doors tend to work particularly well in smaller or darker rooms, since they reflect light and create a sense of additional space. A plain or matte finish may suit a more minimal decor style, though this largely comes down to personal preference.
Is a 100cm wardrobe a good choice for a shared bedroom?
Generally, a 100cm wardrobe suits a single occupant better than two people sharing storage. If the wardrobe needs to serve a couple, a wider option such as a 150cm sliding door wardrobe is usually a more practical choice, since it offers noticeably more hanging space and shelving.
Final Thoughts
A sliding door wardrobe 100cm wide strikes a sensible balance for anyone working with a smaller bedroom, a box room, or a guest space where every centimetre of wall counts. It offers genuine, practical storage without overwhelming the room, and the sliding door mechanism makes it a particularly smart choice wherever floor clearance is tight.
Before making a final decision, take the time to measure your space properly, think honestly about how much you actually need to store, and compare a few finishes to see what suits your room best. Furniture Island’s full wardrobe collection covers a wide range of widths and styles, including the 100cm, 120cm, and 150cm options discussed throughout this guide, making it easy to compare your options in one place.
