Complete Singapore Mattress Size Chart

Single Size (91×190cm)

A Single mattress is 91cm wide by 190cm long—ideal for children or petite adults. In Singapore's typical HDB common room (2.7m × 2.4m), a Single mattress fits easily, leaving space for wardrobes and other furniture. It's also popular for bunk beds and small guest rooms.

Super Single (107×190cm)

The Super Single is Singapore's most popular size for single adults, offering 16cm more width than a Single without taking up excessive space. It's the "Goldilocks" size for HDB common rooms—spacious enough for comfortable sleep but not so large that it dominates the room. Perfect for people who want more breathing room during sleep.

Queen Size (152×190cm)

Queen is the most popular size for couples and fits comfortably in HDB master bedrooms (typically 3.7m × 3.8m). It offers good balance between personal space and room utilization. Two adults get reasonable sleeping space without the mattress overwhelming the bedroom.

King Size (182×190cm)

King mattresses are 182cm wide by 190cm long, ideal for larger bedrooms in condominiums or bigger HDB units. Best for couples who want maximum personal space, or families co-sleeping with children. Requires a spacious master bedroom to avoid feeling cramped.

Split King – Two Adjustable Bases

A Split King comprises two Single mattresses (or adjustable bases) side by side, creating a 182cm-wide bed. Ideal for adjustable bed frames, allowing each partner to adjust firmness, incline, and height independently. Popular for couples with different sleep needs.

Singapore vs International Sizes

Notice: Singapore sizes are typically 10–13cm shorter than US/UK sizes and differ from European sizes. Always verify dimensions before purchasing online, especially from international retailers.

How to Choose the Right Size

1. Measure Your Bedroom – Ensure at least 60cm clearance on each side for comfort and movement

2. Check Your Bed Frame – Measure your existing frame; mattress must fit snugly without overhang

3. Consider Number of Sleepers – Singles for one person; Queen for couples; King for extra space

4. Account for Sleepers' Size – Heavier or taller individuals benefit from larger sizes

5. Think About Budget – Larger sizes cost more; balance comfort with affordability

FAQ

Are Singapore sizes the same as US sizes?

No. Singapore sizes are typically 10–13cm shorter than US sizes. A Singapore Queen is 152×190cm, while a US Queen is 152×203cm. Always verify dimensions before purchasing.

What's the difference between Single and Super Single?

Single is 91cm wide; Super Single is 107cm wide (16cm wider). Super Single offers more personal space and is more comfortable for single adults in Singapore's HDB rooms.

Can I fit a King mattress in my HDB master bedroom?

A King (182cm wide) fits in standard HDB master bedrooms, but you'll have limited floor space. Measure first: aim for at least 60cm clearance on each side. If space is tight, a Queen may be more practical.

What size mattress is best for couples?

Queen is ideal for most Singapore couples. It offers good balance of space and fits most master bedrooms. King is perfect if you have a spacious room and want maximum personal space.
