A mattress size chart inches guide can be helpful when you are comparing bed sizes online, reading overseas references, or checking whether a mattress will fit your bedroom. In Singapore, mattress sizes are usually shown in centimetres, but many shoppers still search in inches because bed frames, room plans, and online furniture guides may use both measurements.
Choosing the right mattress size is not only about whether it fits the room. It also affects comfort, movement, shared sleep, storage space, and how easy the bedroom feels to use every day. A mattress that is too small may feel restrictive. A mattress that is too large may make an HDB or condo bedroom feel cramped.
For Singapore homes, it helps to think in both inches and centimetres. The centimetre measurement gives you local accuracy, while inches make it easier to compare with general online guides.
This guide explains common mattress sizes in inches, how they compare in Singapore homes, and what to consider before choosing your mattress.

Why Mattress Size Matters
Mattress size affects how well your bedroom works. It changes how much space you have to sleep, move, clean, open wardrobes, and place furniture.
It Affects Sleep Comfort
A mattress should give the sleeper enough room to rest comfortably. For children, a single mattress may be enough. For taller teens or solo adults, a super single may feel more comfortable. For couples, queen or king size is usually more practical.
If the mattress feels too narrow, you may wake more easily when turning or sharing the bed. For couples, width matters because both sleepers need space to move without disturbing each other.
It Affects Room Flow
In Singapore, many bedrooms need careful planning. A queen mattress may fit an HDB bedroom, but the bed frame, side tables, drawers, and wardrobe doors also need space.
A mattress that looks right on paper may feel too large once the full bed setup is added. Always measure the room as a whole, not only the mattress footprint.
It Affects Long-Term Use
A child may start with a single mattress but eventually need a super single. A couple may start with queen size but prefer king size later if the room allows.
Choosing the right size early can help the room stay practical for longer.
Single Mattress Size in Inches
A single mattress is usually around 36 x 75 inches, or 91 x 190 cm. It is one of the most common choices for children’s rooms, teen rooms, guest rooms, helper rooms, and compact solo bedrooms.
Who It Suits
A single mattress can work well for one child, one teen, or one adult who does not need much sleeping width. It is also useful for rooms where space must be preserved for study, storage, or play.
In HDB and condo bedrooms, single size can leave more room for a wardrobe, desk, and walking space. This makes it practical for children’s rooms and guest setups.
What to Consider
Single size may feel limiting for adults who turn often or prefer more personal space. If the room can fit it, a super single may offer more comfort while still staying compact.
For a more focused breakdown, Somnuz’s single mattress size guide can help you decide whether single size fits your room and sleeper.
Super Single Mattress Size in Inches
A super single mattress is usually around 42 x 75 inches, or 107 x 190 cm. It gives more width than a single mattress while staying smaller than a queen.
Who It Suits
Super single is often a good choice for teens, solo adults, and guest rooms where comfort matters but space is still limited.
It can be a sensible upgrade from single size if your child is growing quickly or if a solo sleeper wants more turning space.
What to Consider
A super single mattress takes up more room than a single, so measure the bedroom carefully. Check whether wardrobe doors, drawers, and walking space still work comfortably.
If the room is very compact, single size may still be more practical.
Queen Mattress Size in Inches
A queen mattress is usually around 60 x 75 inches, or 152 x 190 cm. It is one of the most common choices for couples in Singapore.
Who It Suits
Queen size works well for many couples because it gives enough shared space without taking up as much room as a king. It is often used in HDB master bedrooms, condo bedrooms, and guest rooms where couples may stay.
What to Consider
A queen mattress needs enough clearance around the bed. If the room is tight, large bedside tables or bulky bed frames may make movement difficult.
For couples, comfort is not only about size. Motion control, support, and breathability also matter. You can compare our mattresses to understand how different Somnuz options support shared sleep.
King Mattress Size in Inches
A king mattress is usually around 72 x 75 inches, or 183 x 190 cm. It gives couples more width and can make shared sleep feel more spacious.
Who It Suits
King size may suit couples who want more personal space, parents who occasionally share the bed with a young child, or sleepers who turn often.
It can work well in larger condo rooms, landed homes, or spacious master bedrooms.
What to Consider
King size needs careful planning. The mattress may fit, but the full bed frame may make the room feel crowded. Delivery access should also be checked, especially in homes with narrow corridors or tight bedroom entrances.
If your room does not comfortably allow walking space around the bed, a queen mattress may be more practical.
How to Measure Your Room Before Choosing
A mattress size chart inches guide is useful, but room measurement is what confirms the right choice.
Measure the Mattress Area
Start with the area where the bed will go. Mark the width and length using tape if needed. This helps you visualise how much floor space the mattress will take.
Include the Bed Frame
A bed frame is often wider and longer than the mattress. If you are using a storage bed, platform bed, or upholstered frame, check the full outer dimensions.
Check Furniture Clearance
Open wardrobe doors, drawers, and room doors. Make sure the bed will not block daily movement.
Leave enough space to change bedsheets and clean around the bed.
Think About Bedroom Use
A child’s room may need space for a study desk. A guest room may double as a home office. A master bedroom may need space for two people to move comfortably.
The right size should support the room’s daily purpose.
Mattress Size and Mattress Type
Once you know the size, think about the mattress feel.
A memory foam mattress may suit sleepers who like a cushioned, contouring feel. A latex mattress may suit those who prefer a breathable and responsive surface. A pocketed spring mattress may suit sleepers who want structured support and airflow through the mattress core.
In Singapore’s humid climate, breathability matters across every size. Larger mattresses for couples may also need better motion control and support so both sleepers feel comfortable.
Choosing the Right Size With Confidence
A mattress size chart inches guide can help you compare single, super single, queen, and king sizes more clearly. But the best mattress size is the one that fits both your body and your room.
Start with the measurements, then think about who will use the mattress, how much space they need, and how the room functions every day.
For the clearest choice, browse the full Somnuz mattress collection, compare sizes and comfort types, then try the mattress in person if you are unsure.
