King Size Bed Dimensions Singapore: Mattress Measurements and Room Fit
A practical Singapore guide to king mattress measurements, frame footprints, room clearance, delivery access, and bedding fit.
- A common Singapore king mattress measures about 183 cm x 190 cm, or 72 x 75 inches.
- The bed frame is larger than the mattress, so measure the complete product footprint before ordering.
- King works best in a master bedroom that still allows wardrobe, door, and walking clearance.
- Imported and IKEA sizes can differ from common local dimensions; compare centimetres, not labels alone.
A common Singapore king size bed measurement is about 183 cm x 190 cm, or 72 inches x 75 inches, for the mattress itself. This is the common local king measurement published by established Singapore mattress brands, but it is not universal.
Imported king mattresses, IKEA products, bed frames, and super-king products can use different dimensions. Compare the exact width and length in centimetres before buying a mattress, frame, protector, or fitted sheet.
King size bed dimensions Singapore: the short answer
| Item | Common measurement |
|---|---|
| Singapore king mattress | 183 cm x 190 cm |
| Approximate inches | 72 x 75 in |
| Common sleepers | Two adults; couples sharing with a young child or pet |
| Best room | Master bedroom with verified frame and walkway clearance |
The measurement above covers the mattress. A king bed frame is larger. Upholstered rails, headboards, footboards, storage drawers, and platforms can add meaningful width or length.
Singapore king size bed measurement in cm and inches
The commonly quoted local king mattress is:
- 183 cm wide
- 190 cm long
- Approximately 72 inches wide x 75 inches long
Sealy Singapore lists 183 cm x 190 cm as its local king standard. Other brands may round the width to 182 cm or manufacture within a small tolerance. Treat one centimetre of label variation as a reason to check the actual product, not as evidence that one guide is necessarily wrong.
The 190 cm common local length is shorter than many European, Australian, and American king formats. Imported bedding may therefore be too long, too narrow, or cut for a different mattress depth.
King mattress size vs king bed-frame size
The mattress sits inside or on top of the bed frame. The external frame footprint is larger than 183 cm x 190 cm.
Ask the seller for:
- Overall bed width.
- Overall bed length.
- Headboard depth.
- Footboard depth.
- Storage drawer extension.
- Recommended clearance for hydraulic storage.
- Delivery-package dimensions.
A slim platform frame may stay close to the mattress width. A padded frame can add several centimetres on each side. A statement such as “fits a king mattress” does not tell you how much floor space the bed uses.
Can a king size bed fit in an HDB master bedroom?
It can fit some HDB master bedrooms, but physical fit is not the same as a usable layout.
Before choosing king, test whether the room still allows:
- The bedroom door to open fully.
- Wardrobe doors and drawers to open.
- A clear route from the door to the bed.
- Access on at least one side for changing sheets.
- Space for bedside storage, sockets, and curtains.
- Any cot, desk, vanity, or mobility equipment the room needs.
Use the complete frame measurements, not the mattress dimensions. Mark the footprint with painter's tape and walk around it. The free bedroom layout planner can help compare arrangements before you move furniture.

King vs queen dimensions in Singapore
| Size | Common local mattress dimensions | Difference |
|---|---|---|
| Queen | 152 cm x 190 cm | Baseline |
| King | 183 cm x 190 cm | About 31 cm wider |
The common local length is the same. King adds about 31 cm of total width, which is roughly 15.5 cm more per sleeper when two adults share the bed.
That extra width can help when:
- Both sleepers move frequently.
- One or both sleepers have broad shoulders.
- A young child occasionally joins the bed.
- A pet sleeps between or beside the couple.
- The couple values personal sleep space more than extra floor space.
Queen is often the better decision when king would block storage or narrow the main walkway. Compare the dedicated queen size mattress Singapore guide before choosing.
Singapore king vs imported king and IKEA king
Size labels change across markets.
- A common Singapore king is about 183 cm x 190 cm.
- IKEA Singapore commonly sells king mattresses around 180 cm x 200 cm.
- Some international king mattresses are about 193 cm x 203 cm.
- Super king can refer to several widths and lengths depending on the brand.
These differences matter for frames, fitted sheets, protectors, toppers, and delivery. A sheet labelled “king” may fit its home market perfectly and still fit a Singapore king poorly.
Buy by exact dimensions. If you mix a frame, mattress, and bedding from different brands, verify all three measurements: width, length, and depth.
What about super king?
Super king is not one universal Singapore size. Local bedding sellers may use dimensions near 200 cm x 200 cm, while imported products can differ.
Before buying super king:
- Confirm the mattress measurement.
- Confirm the frame footprint.
- Confirm lift and doorway access.
- Check whether replacement sheets are easy to buy.
- Consider whether the room still functions with the bed installed.
King is already a large local mattress. Super king should be treated as a product-specific measurement rather than a standard label.
How to measure a room for a king bed
Measure the fixed room
Record wall lengths and the positions of doors, windows, columns, air-conditioning units, sockets, and built-in furniture.
Add the full frame
Use the seller's external width and length. Add drawer extension or hydraulic access if applicable.
Test circulation
Aim for a route that feels comfortable for the people using the room. A planning allowance around 60 cm is useful where space permits, but mobility needs can require more.
Test furniture movement
Open wardrobes, bedside drawers, bathroom doors, and balcony doors. Pull out chairs and storage bins.
Check delivery access
Measure lift doors, corridor corners, stair landings, and the bedroom entrance. The mattress may flex; a rigid king headboard may not.
Mattress depth, toppers, and king sheets
Width and length do not guarantee bedding fit. Measure from the bottom of the mattress to the top after adding any protector or topper.
A fitted sheet needs enough pocket depth to wrap under the mattress without pulling off the corners. If you use a topper, read the natural latex mattress topper guide and include the topper in your depth measurement.
Use the bed sheet sizes Singapore guide before ordering local or imported king sheets.
Comfort and cooling on a larger mattress
A larger surface does not automatically sleep cooler. Temperature depends on the cover, comfort materials, room airflow, protector, sheets, and whether two people share the bed.
For Singapore bedrooms, check:
- Breathability under real bedding.
- Support for both sleepers' positions.
- Motion transfer when one person turns.
- Edge stability when using the full width.
- Airflow under the mattress and bed base.
For more detail, see the cooling mattress Singapore guide.
King size bed buying checklist
- Confirm the exact mattress dimensions in centimetres.
- Confirm the full external frame footprint.
- Mark the bed and furniture clearances on the floor.
- Compare queen if king makes the layout difficult.
- Measure delivery access for the mattress and frame.
- Check fitted-sheet width, length, and pocket depth.
- Confirm trial, delivery, exchange, and warranty terms.
- Decide whether the extra width solves a real sleep problem.
For smaller solo rooms, use the single and super-single size guide.
Frequently Asked Questions
What is the standard king size bed measurement in Singapore?
A common local king mattress is about 183 cm x 190 cm, or 72 x 75 inches. Exact measurements vary by manufacturer.
Is a Singapore king 182 cm or 183 cm wide?
Both figures appear because of rounding and manufacturer differences. Check the exact product specification and frame opening before buying.
Can a king bed fit in an HDB master bedroom?
It can fit some HDB master bedrooms, but you must test the full frame footprint, wardrobe access, door swing, and walking route.
How much wider is king than queen in Singapore?
A common king is about 31 cm wider than a common queen. Both are commonly 190 cm long.
Is IKEA king the same as Singapore king?
Not usually. IKEA king products are commonly around 180 cm x 200 cm, while the common local king is about 183 cm x 190 cm.
Can I use imported king sheets on a Singapore king?
They may fit poorly because imported king widths, lengths, and pocket depths differ. Compare exact sheet and mattress measurements.
Is king size worth it for two adults?
It can be worthwhile when both sleepers value extra personal space and the room remains functional. Queen may be better when king compromises storage or movement.
What mattress size should a couple choose for an HDB flat?
Queen is the common starting point. Choose king only after confirming the complete room layout and frame dimensions.
Does a king mattress need a special bed frame?
It needs a frame designed for its exact dimensions and support requirements. Do not assume every frame labelled king matches every king mattress.
What should I measure before ordering a king bed?
Measure the mattress, external frame, room, wardrobes, door swings, walkway, lift, corridor turns, and fitted-sheet pocket depth.
Conclusion
The common Singapore king mattress is about 183 cm x 190 cm, but the decision depends on more than the label. Measure the actual product, complete frame, room circulation, delivery route, and bedding. King is useful when the extra width improves shared sleep without making the bedroom harder to use.
