Australia vs International Mattress Sizes: Complete Guide Before You Buy
Are Australian Mattress Sizes the Same as International Sizes?
No. Australian mattress sizes are not always the same as US, UK, European, or mattress sizes.
Some sizes are very close. For example, an Australian queen mattress is similar to a US queen mattress. But other names can be misleading. A UK king is much smaller than an Australian king mattress and many European mattresses use a 200 cm length as standard.
The safest rule is simple: do not rely on the mattress name alone. Check the width and length in centimetres before buying.

Australia vs International Mattress Size Chart
This chart compares common Australian mattress sizes with US, UK, European, New Zealand sizing.
| Size Category | Australia | US | UK | Europe | New Zealand |
|---|---|---|---|---|---|
| Single / Twin | 91.5 x 190 cm | 96.5 x 190.5 cm | 90 x 190 cm | 90 x 200 cm | 91.5 x 190 cm |

| Queen | 152.5 x 203 cm | 152.5 x 203 cm | Often not the same as AU queen | Often 160 x 200 cm or 152 x 202 cm | 152.5 x 203 cm |
| King | 183.5 x 203 cm | 193 x 203 cm | 150 x 200 cm | Often 180 x 200 cm | 168.5 x 203 cm |
| Super King | 203 x 203 cm | Varies by retailer | 180 x 200 cm | Often 180 x 200 cm or larger | 183.5 x 203 cm |
The key issue is that mattress names are reused across countries, but the actual measurements can change.
Closest International Matches to Australian Mattress Sizes
Use this table if you are trying to match an overseas mattress, bed frames , or bedding set with an Australian size.
| Australian Size | Closest International Match | What to Check Before Buying |
|---|---|---|
| Single | UK single / US twin | US twin is usually wider than AU single. |
| Double | US full / UK double | Similar, but not always exact. |
| Queen | US queen | Usually one of the closest matches. |
| King | European 180 x 200 cm / UK super king | Similar width, but length may differ. |
| Super King | Limited direct match | Always check exact width and length. |
This section is important because many shoppers buy bedding or bed frames from overseas websites and only realise the sizing issue after delivery.
Why Mattress Sizes Differ Between Countries
Mattress sizes differ because each market has developed its own sizing system. Australia, the US, UK, Europe and New Zealand all use slightly different standards.
The problem is not just the measurement system. It is the naming. A “king” in the UK is not the same as a “king” in Australia. A “full” mattress in the US is close to an Australian double, but the name is different.
This can affect:
- Mattress fit
- Bed frame compatibility
- Fitted sheets
- Mattress protectors
- Quilt size
- Headboard alignment
- Bedroom spacing
For this reason, the centimetre measurement matters more than the size name.
Double vs Queen Mattress: Which Size Is Better?
A double mattress and a queen mattress are two of the most common choices for Australian bedrooms. The right one depends on the room size, sleeper height, and whether one or two people will use the bed every night.
| Feature | Double Mattress | Queen Mattress |
|---|---|---|
| Common Australian Size | 138.5 x 190 cm | 152.5 x 203 cm |
| Width | Narrower | Around 14 cm wider |
| Length | Shorter | Around 13 cm longer |
| Best For | Solo sleepers, teens, guest rooms, smaller bedrooms | Couples, taller sleepers, main bedrooms |
| Everyday Couple Use | Can feel tight | Better long-term choice |
| Room Space Needed | Easier in compact rooms | Needs more floor space |
| Bedding Availability | Easy to find | Very easy to find |
| Best Buying Reason | Space-saving and budget-friendly | Better comfort and future flexibility |
A double mattress is a practical option for a guest room, teenager’s room, smaller rental, or solo sleeper who wants more space than a single.
A queen mattress is usually the better choice for couples and taller sleepers because it gives more width and length. If the mattress is for a main bedroom, queen is often the safer long-term option.

Will an International Mattress Fit an Australian Bed Frame?
Sometimes, but not always.
A mattress should sit neatly on or inside the frame without large gaps, overhang, or pressure against the side rails. Even a difference of 2–5 cm can matter, especially with storage beds, platform frames, recessed bases, and frames with raised edges.
Before pairing an imported mattress with Australian bed frames , check:
- Mattress width
- Mattress length
- Bed frame internal width
- Bed frame internal length
- Side rail height
- Whether the frame has a recessed base
- Fitted sheet depth
- Mattress protector size
- Return policy
If you are buying a new mattress and frame together, choosing the same size family is the safest option.
How to Measure Your Mattress and Bed Frame Properly
Use a tape measure and write the dimensions down in centimetres.
Step 1: Measure the mattress space
Measure the inside width of the frame from one side rail to the other.
Step 2: Measure the internal length
Measure from the inside top edge to the inside bottom edge of the bed frame.
Step 3: Check the frame lip
Some bed frames have a raised edge that holds the mattress in place. If the mattress is too large, it may not sit flat.
Step 4: Check mattress height
Mattress height matters for fitted sheets, mattress protectors, and how high the bed feels when you sit on it.
Step 5: Allow for movement
A mattress should fit securely, but it should not be forced into the frame. A tight fit can make changing sheets harder and may affect how the mattress sits.
Before Buying an International Mattress: Quick Checklist
Use this checklist before you buy a mattress, frame, sheets, or mattress protector from another country.
| Checkpoint | Why It Matters |
|---|---|
| Width in centimetres | Size names can be misleading. |
| Length in centimetres | Taller sleepers need enough legroom. |
| Frame internal dimensions | The mattress must fit the actual frame space. |
| Frame type | Recessed frames and raised edges need more precise sizing. |
| Sheet size | International fitted sheets may not fit well. |
| Mattress protector depth | Deep mattresses need deeper protectors. |
| Return policy | Size mistakes can be expensive to fix. |
Once you know your mattress size, match it with the right bed sheets and mattress protector so the fit stays secure through the night.
Which Mattress Size Should You Choose?
Choose a Single Mattress If:
You are buying for a child, small bedroom, bunk bed, or compact guest space.
Choose a King Single Mattress If:
You want more length for a growing teenager, tall child, or solo adult in a narrow room.
Choose a Double Mattress If:
You are a solo sleeper who wants extra space but does not have room for a queen. A double mattress is also useful for guest rooms and smaller apartments.
Choose a Queen Mattress If:
You are buying for a couple, main bedroom, or taller solo sleeper. A queen mattress is one of the most practical mattress sizes in Australia because it balances comfort, space, and bedding availability.
Choose a King Mattress If:
You share your bed with a partner, child, or pet and want more personal sleeping space. A king mattress needs a larger bedroom, but it can feel more comfortable for long-term use.
Choose a Super King Mattress If:
You have a large bedroom and want maximum sleeping space. This size is best for people who prioritise space over budget and room flexibility.
Best Mattress Size by Room Type
| Room Type | Best Mattress Size |
|---|---|
| Child’s room | Single or king single |
| Teenager’s room | King single or double |
| Guest room | Double or queen |
| Small apartment bedroom | Double or queen |
| Main bedroom | Queen or king |
| Large master bedroom | King or super king |
| Shared family bed | King or super king |
For most Australian homes, a queen mattress is the most balanced option. It fits many bedrooms, suits couples, and gives more length than a double mattress.
Complete Your Bedroom Setup
Choosing the right mattress size is only one part of the setup. To get a better fit and a more comfortable bedroom, match your mattress with the right accessories.
A fitted mattress protector helps keep the mattress fresh and protected from spills, sweat, and daily wear. Properly sized bed sheets help prevent bunching, slipping, and loose corners.
You can also improve comfort with supportive pillows and season-ready quilts , especially if you are refreshing the full bedroom setup rather than replacing the mattress only.
Common Mattress Size Mistakes to Avoid
Mistake 1: Buying by name only
A queen, king, or double does not always mean the same thing overseas. Always check the actual size.
Mistake 2: Forgetting the bed frame
A mattress may technically be the right category but still not fit the frame properly.
Mistake 3: Ignoring sheet depth
Fitted sheets and mattress protectors need to match both the mattress size and mattress height.
Mistake 4: Choosing too large for the room
A bigger mattress is not always better if it leaves no walking space or blocks wardrobes and drawers.
Mistake 5: Assuming international sizes match Australian sizes
International mattress names can look familiar, but the measurements may not match. Always compare the width and length in centimetres before buying.
Australia vs US Mattress Sizes
Australian and US queen mattresses are very similar, which makes queen one of the easier sizes to compare across the two countries.
However, US king mattresses are usually wider than Australian king mattresses. This means US king sheets, protectors, and bed frames may not always suit an Australian king mattress.
If you are buying from a US website, check the product page carefully and convert inches to centimetres before ordering.
Australia vs UK Mattress Sizes
UK mattress sizes can confuse Australian shoppers because the names sound familiar but the dimensions are different.
A UK king is commonly closer to an Australian queen than an Australian king. That means a UK king mattress will usually not fit an Australian king frame correctly.
If you are buying UK bedding, check the actual measurements rather than assuming the label will match.
Australia vs European and Mattress Sizes
European mattress sizes often use 200 cm as a standard length. Common European sizes include 140 x 200 cm, 160 x 200 cm, and 180 x 200 cm.
These can be close to some Australian sizes, but they are not always interchangeable. For example, a European 180 x 200 cm mattress is close to an Australian king in width, but it is usually shorter than an Australian king.
Before buying, compare the product dimensions with your bed frame, mattress protector, and sheet size.

Final Buying Advice
When comparing Australia vs international mattress sizes, treat the size name as a guide only. The real answer is always in the measurements.
If you are buying for a main bedroom, a queen mattress is usually the safest all-round choice. It works well for couples, suits taller sleepers better than a double, and has strong bedding availability in Australia.
If you are buying for a guest room, teenager’s room, or smaller apartment, a double mattress may be the smarter option because it saves space while still offering more comfort than a single.
If you want more personal space, a larger bedroom layout, or extra room for kids and pets, a king mattress may be worth the upgrade.
Before you order, measure your room, measure your frame, check the mattress dimensions, and make sure your sheets and mattress protector will fit.
