101 Guide to Mattress Sizes in Singapore (2026)

Buying a mattress in Singapore? Don't get the size wrong. This updated 2026 guide covers all standard Singapore mattress sizes — with exact dimensions, who each size suits, and how to match your mattress to your bed frame and bedroom space.

Whether you're furnishing a new BTO flat, upgrading a resale HDB, or fitting out a condo bedroom, choosing the right mattress size is one of the most important decisions you'll make. Get it wrong and your mattress won't fit your bed frame — or worse, it'll overwhelm your room.

Standard Mattress Sizes in Singapore

Singapore uses its own standard mattress sizing, which differs slightly from US, UK, and European sizes. There are four main sizes you'll encounter at local retailers:

Single Size Mattress

Best for: Children, teenagers, or petite adults. Ideal for small HDB bedrooms and condos where space is tight.

The Single is the smallest standard size in Singapore. Its compact footprint makes it a popular choice for kids' rooms and guest rooms, and it pairs well with single bed frames and bunk beds.

Dimensions: W 91 cm × L 190 cm (W 36 in × L 75 in)

Super Single Size Mattress

Best for: Growing teenagers or adults who sleep alone and want more room to move.

The Super Single offers 18% more width than a Single — a meaningful upgrade for anyone who tosses and turns. It's the most popular size for adult singles in Singapore, striking a good balance between comfort and space-saving.

Dimensions: W 107 cm × L 190 cm (W 42 in × L 75 in)

Queen Size Mattress

Best for: Couples, or a single adult who wants generous sleeping space.

The Queen is the most popular size for couples in Singapore. It comfortably fits two adults and is a practical choice for master bedrooms in 3-room and 4-room HDB flats, where a King might feel too large. It pairs well with queen bed frames.

Dimensions: W 152 cm × L 190 cm (W 60 in × L 75 in)

King Size Mattress

Best for: Couples who want maximum space, or families who co-sleep with a child or pet.

The King is the largest standard size in Singapore. It's a luxurious choice for spacious master bedrooms in 5-room HDB flats, executive apartments, or condos. If you have the room for it, the King delivers the best sleep quality for couples.

Dimensions: W 182 cm × L 190 cm (W 72 in × L 75 in)

Singapore vs Overseas Mattress Sizes

This is one of the most common mistakes Singapore buyers make — assuming that a "Queen" or "King" mattress from an overseas brand matches local dimensions. They often don't.

For example, a US Queen is 153 cm × 203 cm, while a Singapore Queen is 152 cm × 190 cm — 13 cm shorter. This matters because your bed frame, bed sheets, and mattress protector are all sized to match. Always check the exact dimensions in centimetres before buying, especially from international brands or online marketplaces.

How to Choose the Right Mattress Size for Your Room

A good rule of thumb: leave at least 60–90 cm of walking space on each side of the bed. Here's a quick guide by room size:

• Small bedroom (under 9 sqm): Single or Super Single
• Medium bedroom (9–12 sqm): Super Single or Queen
• Large bedroom (12 sqm and above): Queen or King

Also consider your bed frame dimensions — the mattress should sit flush within the frame with no overhang.

Frequently Asked Questions

What is the most popular mattress size in Singapore?

Queen size is the most popular mattress size in Singapore for couples, while Super Single is the top choice for single adults. Both offer a good balance of comfort and space-efficiency for typical HDB and condo bedrooms.

Is a Singapore Queen the same as a US Queen?

No. A Singapore Queen mattress is 152 cm × 190 cm, while a US Queen is 153 cm × 203 cm. The Singapore version is 13 cm shorter in length. Always verify dimensions in centimetres before purchasing.

What mattress size fits a 3-room HDB master bedroom?

Most 3-room HDB master bedrooms comfortably fit a Queen size mattress (152 cm × 190 cm). A King size may fit but will leave limited walking space. Measure your room carefully and account for wardrobe and other furniture clearance.

Can I use an overseas mattress with a Singapore bed frame?

It depends on the exact dimensions. Singapore bed frames are sized to local mattress standards, so an overseas mattress may not fit correctly. Always compare the exact cm dimensions of both the mattress and bed frame before purchasing.

What mattress size should I get for a bunk bed?

Most bunk beds in Singapore are designed for Single size mattresses (91 cm × 190 cm). Some models accommodate Super Single on the lower bunk. Check the specific bunk bed specifications before ordering a mattress.
