Before buying a queen mattress, knowing the exact dimensions in centimetres is one of the most practical steps you can take. It helps you confirm whether the mattress will fit your bed frame, suit your room layout, and work for whoever will be sleeping on it.
This guide covers the precise queen mattress dimensions in Singapore, how they compare to other standard sizes, and what to check before you finalise your purchase.
Queen Mattress Dimensions in Centimetres
A standard queen mattress in Singapore measures approximately 152 cm wide by 190 cm long. Thickness varies by model and quality tier — basic options typically range from 20 to 25 cm, while higher-quality mattresses with additional comfort layers are often 28 to 32 cm tall.
These dimensions are consistent across most Singapore mattress brands, though minor variations of 1 to 2 cm can exist. Always confirm the exact centimetre measurements of any specific mattress before purchasing.
How Queen Compares to Other Mattress Sizes in Singapore
• Single: 91 cm x 190 cm
• Super single: 107 cm x 190 cm
• Queen: 152 cm x 190 cm
• King: 183 cm x 190 cm
• Super king: approximately 200 cm x 200 cm
The difference between a super single and a queen is approximately 45 cm in width — a significant jump that makes the queen much more suitable for shared sleep. The difference between a queen and a king is about 31 cm in width, which gives each person in a shared bed roughly one additional standard-single worth of personal space.
Using the Dimensions Practically
Checking Your Bed Frame
A queen bed frame is built with internal dimensions to hold a 152 cm wide mattress. Before buying a new mattress, measure the internal width and length of your existing frame. A mattress that is too wide will not sit correctly; one that is too narrow will shift during sleep.
If you are buying a new frame at the same time, confirm the internal dimensions match the mattress measurements — and check that slats are spaced no more than 5 to 7 cm apart for adequate mattress support.
Planning Your Room Layout
A 152 cm wide mattress in a room requires enough clearance around the bed to feel accessible and comfortable. Aim for at least 60 cm of space on each sleeping side and at the foot of the bed. This means your room should be at least 2.8 to 3 metres wide to accommodate a queen comfortably alongside bedside tables.
If your room is narrower than that, a super single at 107 cm wide may leave more usable space while still providing a generous solo sleep surface.
Buying the Right Bedding
Queen fitted sheets, mattress protectors, and duvets are sized for a 152 cm wide mattress. When buying bedding, confirm the dimensions match — and check the pocket depth of any fitted sheet to ensure it fits the thickness of your specific mattress.
What the Dimensions Do Not Tell You
Knowing the size is an essential starting point, but the dimensions tell you nothing about how the mattress feels, how well it breathes, how long it will last, or whether it suits the way you sleep. Those things are determined by the materials inside — the support core, comfort layers, and cover fabric.
Once you have confirmed the dimensions are right for your room and frame, evaluating the construction and trying the mattress in person are the next most important steps.

Frequently Asked Questions
What is the exact size of a queen mattress in Singapore in cm?
A standard queen mattress in Singapore is approximately 152 cm wide by 190 cm long. Thickness varies by model. Always confirm the exact dimensions of any specific mattress before purchasing.
Is a queen mattress the same size in Singapore and Australia?
Australian queen mattresses are typically 153 cm wide by 203 cm long — slightly wider and longer than the Singapore standard. If you are buying a frame or bedding from an Australian source, confirm the dimensions carefully to ensure compatibility.
How do I measure if a queen mattress will fit my room?
Measure the full width and length of your room. Subtract the mattress width (152 cm) from the room width and check whether the remaining space allows at least 60 cm of clearance on each sleeping side. Repeat for the length, leaving clearance at the foot of the bed for airflow and comfortable movement.
What bed frame size do I need for a queen mattress?
A queen bed frame with internal dimensions of approximately 152 cm wide by 190 cm long. Always measure the frame's internal dimensions rather than the external frame size to confirm the mattress will fit properly.
Can I use king size bedding on a queen mattress?
No. King bedding is sized for a 183 cm wide mattress and will be too wide and long for a queen. Always use bedding specifically sized for queen dimensions to ensure a proper fit.
