Super Single Mattress Size: Dimensions & Who It Suits (2026)

If you have shopped for a bed in Singapore, you have almost certainly seen the super single sitting between the plain single and the Queen. It is one of the most popular sizes sold here, yet many people are not sure exactly how big it is or who it is really for. The short answer: it is the size that solves the classic HDB bedroom problem of a single feeling too narrow but a Queen not fitting.

Exact super single mattress dimensions

A super single mattress in Singapore measures roughly 107 x 190 cm, which is about 42 x 75 inches. Some premium ranges come in a longer 198 or 200 cm option, useful if you are tall, but the standard length you will meet in most shops is 190 cm.

The important thing to understand is that the super single is wider than a single but exactly the same length. All of the extra room is width — about 16 cm more than a single — which translates directly into more shoulder and elbow space for one sleeper.

Note that these are mattress figures. A bed frame is always larger than the mattress it holds, so plan your room around the frame, not the number on the mattress label.

A distinctly Singapore size

The super single is not a global standard. It is common in Singapore and Malaysia and largely unknown in Europe and North America. The nearest overseas cousin is the US Twin XL, but that is narrower and longer, so it is not a true match.

This matters for two practical reasons. First, if you buy bedding while travelling or from an overseas site, super single sizing may simply not exist, so stick to local retailers. Second, the size exists precisely because it answers a local need: compact HDB bedrooms where every centimetre counts but a single feels mean for anyone past childhood.

What room size and clearance it needs

A super single is a genuinely space-friendly choice. In a typical HDB common bedroom of around 2.4 to 3 metres on a side, a super single leaves room for a wardrobe, a small desk and a walkway. Placed against one wall, it fits most rooms without dominating them.

For comfortable movement, aim for at least 60 cm of walking clearance on the side you get in and out from, and ideally the same at the foot if the room allows. If the bed only needs to be accessed from one side, you can push the other side against a wall and reclaim that space for storage. This one-sided access trick is what makes the super single so forgiving in tight rooms.

To put the footprint in context, a super single frame typically occupies about 1.2 metres of wall width once you account for the frame, versus roughly 1.65 metres for a Queen. In a room that is only 2.4 metres wide, that saved half-metre is often the difference between fitting a wardrobe on the opposite wall and not. If you are furnishing a study-bedroom or a room that doubles as a hobby space, the super single leaves you a genuinely usable strip of floor rather than a token walkway.

If you are still mapping out the room, our guide to bedroom layout ideas for HDB flats shows how to position a bed so the walkway and wardrobe doors do not clash.

Who a super single suits

This size shines for a specific set of people:

• Growing kids and teenagers who have outgrown a single but do not need — and whose room cannot fit — a double or Queen.
• Solo adults in a common bedroom, a rental room or a study-bedroom who want to stretch out without giving up floor space.
• Guest rooms where you want something more generous than a single but still compact.

Where it does not suit is regular couple sleeping. Two adults on a super single get roughly 53 cm of width each, which is narrower than a typical single sleeper enjoys. It is fine for the occasional shared night, but for two people every night you want a Queen.

Bedding and bedsheets at this size

Super single bedding is easy to find in Singapore. Fitted sheets, bedsheet sets and mattress protectors are all sold in this size at local department stores, bedding specialists and online. The choice is not as vast as Queen — the largest range of prints, materials and premium sets is always aimed at Queen and King — but you will not struggle to dress the bed.

Two tips. Check the pocket depth of a fitted sheet against your mattress thickness, especially if you add a topper, and buy sheets labelled super single rather than single, since a single sheet will be too tight and a super single sheet on a single bed will sag. If you are choosing fabric for our climate, our notes on bedsheets for Singapore humidity are worth a read.

Upgrade and downsize trade-offs

Compared with a single, the super single costs a little more and takes up a little more width, but the comfort gain for anyone above primary-school age is real. For most adults it is the better buy of the two.

Compared with a Queen, the super single saves noticeable floor space and money, but you give up the ability to comfortably share the bed. If your room can take a Queen and there is any chance of sharing, think carefully before committing to a super single. To weigh that jump properly, see our overview of what mattress size to choose in Singapore.

There is also a resale-value angle worth a thought. Because the super single is one of the most-bought sizes for children’s and guest rooms in Singapore, a good-condition super single frame or mattress tends to move quickly on the second-hand market when the child grows up or you reconfigure the flat. That liquidity is a quiet bonus of choosing a locally popular size rather than an unusual one.

Frame choice also matters at this size. A storage or platform frame turns the footprint into useful drawer space, which is valuable in a small room. Our guide to choosing furniture for your home covers how frame style changes the total footprint you need to plan for.

The bottom line

The super single mattress size — about 107 x 190 cm or 42 x 75 inches — is Singapore’s practical middle ground. It gives a single sleeper meaningfully more room than a plain single while still fitting the compact bedrooms that most HDB flats offer. It is the natural choice for a growing child, a teenager or a solo adult, and it keeps floor space and cost down.

Just remember its one limit: it is a one-person bed. If two people will share it every night, or if your room can comfortably take a Queen, size up instead. For everyone else, the super single remains one of the smartest, most space-efficient sizes you can buy here.
