Common sizing standards in Singapore
You might be familiar with mattresses coming in sizes Single, Super single, Queen, and King. However, beds and mattresses are manufactured according to different sizing standards across the world, so the dimensions of these 4 size descriptors may differ depending on which manufacturer you purchase from! Singapore, the United Kingdom, United States, Europe, Australia, and China all have their own mattress sizing standards.
According to our sample of top mattress retailers, about 82% of mattress models retailed in Singapore are made according to the Singapore (SG) sizing standard, making it the most common sizing standard here. This is followed by a smattering of pan-European (EU) and United States (US) sizes. Ikea Singapore also does not follow the SG sizing standard strictly, utilizing instead a mixture of EU and UK sizes.
In terms of actual dimensions, the United Kingdom (UK) sizing standard is closest to the Singapore sizing standard because their sizes share essentially the same widths, though UK Queen and King beds are 10 cm longer than their Singaporean counterparts. As the average height of Singaporeans continues to increase with better nutrition, more households are finding that longer UK-sized beds allow them to sleep away from the edges and provide better comfort. If you are purchasing a bed for a growing child, you might want to consider more spacious UK-sized beds!
Further confounding the sizing issue, some manufacturers use slightly different dimensions when producing their mattresses. For example, SG King sizes come in both 183 cm and 182 cm widths, and some SG-sized mattresses are 191 cm long instead of 190 cm long! The dimensions assigned to each size reference in this guide is the average for each size, according to SleepWiz’s own research.

Which mattress size is best for me?

SG Single
- 91 cm × 190 cm (36″ × 75″)
- The smallest mattress size in the SG standard.
- Suitable for one person.
- Space efficient for smaller common bedrooms, or rooms that also contain other furniture e.g computer desk, another bed.
- More affordable than the SG Super Single.
- Cheaper to find sheets, duvets, and other bedding than for the SG Super Single.

SG Super Single
- 107 cm × 190 cm (42″ × 75″)
- More spacious option for one person.
- Suitable if you like to spread, or are a larger person. Allows you to toss around without falling off the bed at night.
- More expensive than the SG Single.
- Slightly more costly to find sheets, duvets, and other bedding than for the SG Single.


SG Queen
- 152 cm × 190 cm (60″ × 75″)
- Suitable for couples who like to be cozy, or for one person to splay out very comfortably!
- Space efficient to fit in smaller common bedrooms without making the room look small, and leaves space to walk around.
- More affordable than the SG King.
- Cheaper to find sheets, duvets, and other bedding than for the SG King.

SG King
- 183 cm × 190 cm (72″ × 75″)
- The largest size in the SG standard.
- More spacious option for two people – each person gets the space of a whole Single-sized bed to himself/herself!
- Suitable for couples who need their own space to toss and turn or stay cool. Also a great option for the little ones to snuggle up between you on some nights!
- Suitable for larger master bedrooms; May dominate the space in common rooms and make them look smaller.
- More expensive than the SG Queen.
- Slightly more costly to find sheets, duvets, and other bedding than for the SG Queen.
- May not fit into the lifts of some HDB flats and have to be carried up the stairs – which will cost extra.

What if none of these sizes work for me?
If you require a larger mattress or one that is in between the standard sizes, custom-made mattresses might be the first option to come to mind. However, it might be cheaper to purchase multiple standard mattresses and place them on a custom-made bedframe instead. This is because the construction of mattresses is a lot more intricate than bedframes, and will cost a lot more to customize as a result.
Of course, your bedsheets and duvets will have to be custom-made to fit over the compound mattress as well!
Otherwise, you may also consider mattresses made according to other international sizing standards below.
