- Australian sizes are Single, King Single, Double, Queen, King, and Super King; Queen is the most popular for couples.
- Always measure your bedroom and stairwell access before ordering, since King mattresses do not always fit through tight stairs.
- Future-proof by buying for where you will be in 3 to 5 years, not just today, especially if you plan to share the bed.
- European sizes are slightly different (a European Queen is 160 x 200 cm), so do not mix Australian frames with European mattresses.
- DuuDuu mattresses arrive rolled and compressed, which makes them much easier to move into apartments or up stairs.
Moving into a New Home in Australia? Here's Why Mattress Size Matters
Buying a new home in Australia is an exciting milestone — whether you’re settling into a Perth apartment or a suburban family house in the Victoria, every space deserves the perfect furniture.
At the heart of every bedroom is the bed — and that means choosing the right mattress size.
Many new homeowners overlook just how much mattress dimensions impact sleep quality, room layout, and future-proofing.
In this write-up, we break down standard Australian mattress sizes, how they compare to other global sizes, and what new home buyers need to know to choose the best fit for their new home.
Australian Mattress Sizes: A Quick Overview
Before looking at design or mattress materials, start with size.
Here’s a breakdown of the most common Australian mattress sizes:
| Mattress Size | Dimensions | Great For: |
|---|---|---|
| Single | 92cm x 188cm | Kids, tight spaces |
| King Single | 107cm x 203cm | Teenagers, taller individuals, solo sleepers, Mine sites |
| Double | 138cm x 188cm | Young couples, guest rooms |
| Queen | 153cm x 203cm | Most popular choice for couples |
| King | 183cm x 203cm | Master bedrooms, spacious homes |
| Super King | 203cm x 203cm | Luxury homes, co-sleeping families |
DuuDuu Tip: Always measure your bedroom before buying your mattress!
Why New Home Buyers Should Think Carefully About Mattress Size
1. Room Dimensions & Layout Planning
When moving into a new home, most buyers prioritize kitchens, flooring, or cabinetry.
But if the mattress is too big for the room, it can cause years of poor flow and function.
-
Small apartments or city homes? Consider a Queen or even a Double to leave space for side tables and walkways.
-
Spacious bedrooms in suburban homes? A King or Super King can add that luxe hotel feeling.
2. Future-Proofing for Growth
Many buyers opt for a Queen or King size from the beginning, knowing they may one day share the bed with a partner, pets, or even kids.
Investing in a larger mattress now can save the hassle of upgrading too soon.
3. Furniture Shopping Made Easy
Knowing your mattress size helps when buying a bed frame, linen, and mattress protectors.
At DuuDuu, our range of bed sheets, latex pillows, and waterproof mattress protectors is tailored for Australian sizes — so no more second-guessing if something will fit.
Common Mistakes New Buyers Make When Choosing a Mattress Size
❌ Thinking Bigger is Always Better
Yes, a King size mattress sounds like a dream — but if it cramps the room or blocks a wardrobe, it becomes a nightmare.
Always balance mattress size with room practicality.
❌ Forgetting Entryway & Stair Dimensions
You’d be surprised how often new home buyers can’t fit a King mattress up the stairs.
DuuDuu mattresses are delivered rolled and compressed, making delivery easy, even in tight spaces.
❌ Ignoring Sleeping Habits
If you're a light sleeper, a Queen with motion isolation might be better than a Double. Couples who sleep hot might prefer the space a King offers.
What About European Mattress Sizes?
Some Australians moving from Europe (or ordering bed frames from overseas) might notice size mismatches.
Here's a quick comparison:
| European Size Name | Approximate Dimensions | Closest Australian Equivalent |
|---|---|---|
| Single (EU) | 90cm x 200cm | King Single |
| Double (EU) | 140cm x 200cm | Double |
| Queen (EU) | 160cm x 200cm | Queen |
| King (EU) | 180cm x 200cm |
King |
Buying a mattress overseas to fit an Aussie bed frame?
Not ideal.
Stick with Australian-standard mattresses to ensure everything fits just right.

What size mattress is most popular in new Australian homes?
Queen (153 by 203 cm) by a wide margin. Roughly half of new mattress purchases for primary bedrooms are Queens. They balance comfort, room footprint, and bedding availability. King is the second most common for couples wanting more space.
How much room space do I lose by going from Queen to King?
30 cm of width on the bed translates to 60 to 90 cm less floor space when you account for walking space on both sides. In a 3 by 3.5 metre bedroom, that's the difference between feeling spacious and cramped. Measure carefully.
Can a master bedroom be too small for a Super King mattress?
Yes, easily. A Super King (203 by 203 cm) needs at least a 4.5 by 4.5 metre bedroom for proper clearance. Below that, the mattress dominates the room, leaving inadequate walking space and dwarfing other furniture.
Are Australian Single mattresses too small for adult guests?
Adult guests fit on a Single, but it's noticeably tight, especially for taller or wider adults. King Single is the better minimum for adult guest rooms. Single mattresses are best reserved for kids' rooms or very temporary guest setups.
Should I buy a Queen or King for the master bedroom in our first home?
Queen is the safer first-home choice unless you have a large bedroom or anticipate kids visiting your bed. You can't go wrong with Queen. Going King is great if your room genuinely supports it; in a tight space, you'll regret the extra width quickly.
How much does a King-sized bed frame cost compared to a Queen?
Bed frames are typically 15 to 30 percent more expensive in King than Queen. Match the price difference of the mattress (usually 10 to 20 percent more for King). Total upgrade cost is meaningful but not extreme.
What's the smallest practical mattress size for a long-term couple?
Queen. Anything smaller (Double) is too tight for nightly sharing by adults over a few months. The 15 cm difference between Double and Queen is enormous in real terms. If your room only fits a Double, consider whether the room is suitable for two adults.
Are Australian sizes likely to change in the next decade?
Unlikely. The Australian Standard (AS/NZS 4220) has been stable for decades. Industry inertia and bedding manufacturer commitments keep sizes consistent. Don't worry about future-proofing; standard sizes will remain.
What mattress size suits a teenager's bedroom best?
King Single (107 by 203 cm) for most teens; Double if they're tall or want extra space. King Single accommodates growth spurts (up to 6 foot 7 inches in length) without dominating a typical teen bedroom.
Should I match the mattress size to existing bedroom furniture?
Roughly proportional but you can adjust. Bedside tables can be sized down for smaller mattresses or maintained for larger ones. Don't compromise mattress size for furniture aesthetics; the bed serves your sleep more than your decor.
