Let’s talk about the details of bed mattress size Australia shoppers need to know, and see how brands (with Onebed’s range as a handy example) offer various sizes and even modular options. By the end, you’ll know the dimensions for a double bed, a king single, and everything in between – plus tips on choosing the perfect bed for your space and needs.
Overview of Australian Bed Sizes and Mattress Dimensions
Before picking a mattress, it’s essential to know the standard sizes and their measurements in Australia. Unlike some regions, there’s no international standard – a “queen” size in one country might differ in another. Below is a quick reference table of Australian bed sizes with their mattress dimensions:
Standard Australian Mattress Sizes:
- Single: 92 cm x 188 cm
- Long Single: 92 cm x 203 cm
- King Single: 107 cm x 203 cm
- Double: 138 cm x 188 cm
- Queen: 153 cm x 203 cm
- King: 183 cm x 203 cm
- Super King: 203 cm x 203 cm
| Mattress Size | Dimensions (W × L) | Recommended Room Size | Best Suited For |
|---|---|---|---|
| Single | 92 cm × 188 cm | 2.5 m × 3 m+ | Children, solo sleepers, compact rooms |
| Long Single | 92 cm × 203 cm | 2.5 m × 3 m+ | Taller kids, adults in small rooms, split king setups |
| King Single | 107 cm × 203 cm | 3 m × 3 m+ | Teens, taller adults, narrow bedrooms |
| Double | 138 cm × 188 cm | 3 m × 3 m+ | Solo adults, cozy couples, guest rooms |
| Queen | 153 cm × 203 cm | 3.2 m × 3.2 m+ | Couples, solo sleepers wanting more space |
| King | 183 cm × 203 cm | 4 m × 4 m+ | Couples needing space, families with pets |
| Super King | 203 cm × 203 cm | 4.2 m × 4.2 m+ | Luxury spaces, co-sleeping with kids, large master suites |
These are the mattress sizes Australia commonly uses. Bed frames will generally be a few centimeters larger to accommodate the mattress and bedding. Now, let’s explore each size in detail – including dimensions, who it’s best for, and things to consider.
Single Bed: Dimensions of a Single Mattress Australia
A single bed is the smallest standard size mattress in Australia. Measuring 92 x 188 cm, it’s compact enough to fit in tight bedrooms or studio apartments. This size is often found in children’s rooms or bunk beds, offering a cozy sleep space for one person without taking up much floor space.
- Benefits: Single mattresses are budget-friendly, easy to move, and perfect for kids transitioning from a cot. They’re also good for daybeds or as a spare bed for guests in multipurpose rooms. Because of their size, single bed sizes Australia are a common choice for bunk beds or trundle beds in guest rooms.
- Considerations: A single bed may feel cramped for taller adults or those who move a lot during sleep. If the sleeper is nearing six feet tall (around 183 cm) or still growing, you might consider a long single or king single for extra length.
Onebed tip: If you’re looking for quality in this size, Onebed’s Single Mattress range includes options like the Onebed Original and Onebed X 12” single mattresses, which are designed for comfort and support at this standard size.
Long Single Bed – Extended Comfort for One
A long single is, as the name suggests, a single mattress that’s longer. It has the same width as a standard single (92 cm) but stretches to 203 cm in length. This extra legroom (an additional 15 cm) makes it suitable for taller individuals who need more length than a regular single provides.
- Uses: Long singles are great in narrow bedrooms or guest rooms where width is limited but you don’t want feet dangling off the bed. Two long singles placed side by side equal the size of one king mattress. Because of that, long single mattresses are often used for adjustable split king beds in master bedrooms or hotels – offering flexibility to couples who might prefer different mattress firmness or adjustable bed settings.
- Considerations: Long single beds aren’t as common in households unless specifically needed. Bedding (like fitted sheets) for long singles is available, but be sure to match the 203 cm length when shopping.
King Single Bed – More Room for Growing Sleepers
The king single bed is the largest of the “single” mattresses – both wider and longer than a standard single. At 107 cm wide, it’s 15 cm wider than a normal single, and it shares the long single’s generous 203 cm length (same length as a queen or king mattress).
- Benefits: A king single offers plenty of room for one person to stretch out comfortably. It’s an excellent choice for growing teenagers (hence “king” single) who may find a standard single too narrow or short as they approach adult size. It’s also a good option for guest rooms – providing more comfort for an adult guest than a regular single would.
- Space use: Because a king single is closer to a double bed in width, you need to ensure your room can accommodate its footprint. It’s great for bedrooms that can’t fit a full double bed but have more width to spare than a tiny child’s room. Many college dorms and studio apartments use king single mattresses to offer a bit more luxury to a solo sleeper.
- Considerations: Bedding for a king single (sheets, mattress protectors) should match the 107 x 203 cm size. These are widely available in Australia due to the popularity of the size for older kids and singles. Also, remember a king single mattress won’t fit on a standard single bed frame – you’ll need the correct bed frame size for support.
Onebed example: Onebed’s King Single Mattress range caters to this in-between size, offering the comfort of their foam and hybrid designs in a roomier single format. This shows how Australian bed sizes can vary even within “single” options – something Onebed and similar brands accommodate for customer needs.
Double Bed – Cozy Comfort for Two or Luxury for One
A double bed (also known as a full size in some countries) in Australia is 138 cm wide and 188 cm long. This size can technically accommodate two adults, though it will be a cozy fit. Many Australian homes use a double bed for a single sleeper who wants more room than a single or king single can offer.
- Uses: Double beds are popular for teenagers and young adults, giving them a taste of a larger bed without requiring the space (or expense) of a queen. They’re also common in guest rooms – a double provides a snug yet manageable sleeping space for two if needed.
- Space needs: A double mattress is about 46 cm wider than a single, but it’s the same length as a single (188 cm). So if length isn’t an issue (for example, if no one exceptionally tall will use it), a double could be sufficient for two people. It’s a good middle-ground for smaller master bedrooms or studio apartments where a queen might overwhelm the space.
- Considerations: When two people share a double bed, each person gets roughly the width of a crib mattress (about 69 cm each). For some couples, this can feel cramped, especially if used to a queen or king. If you and your partner don’t mind snuggling close and you need to save space, a double might work; otherwise, consider sizing up for nightly use. Double bed sizes Australia are also sometimes called “full beds” in other markets, but in Australian stores and online, “Double” is the term you’ll see.
Onebed’s offerings: Onebed’s Double Mattress selection provides the same high-quality foam and hybrid options in this versatile size. It’s perfect for someone wanting Onebed’s comfort in a smaller guest room or a main bedroom in an apartment. By choosing a double bed size, shoppers can save money (double mattresses are usually cheaper than queen or king) and still enjoy great comfort.
Queen Bed – Australia’s Most Popular Mattress Size
The Queen bed is by far the most popular mattress size in Australia. At 153 cm wide and 203 cm long, it offers a comfortable amount of space for two adults while still fitting into most bedrooms without trouble. Queens strike a balance between the intimacy of a double and the luxurious sprawl of a king.
- Why choose a Queen: For couples, a queen provides each person roughly 76.5 cm of width – much more than a double gives, improving comfort. It’s also the same length as a king, so even taller individuals (up to about 6’6”) can sleep without feet hanging off the edge. Many master bedrooms in Australia are designed with queen beds in mind.
- Space planning: A queen bed fits well in medium to large bedrooms. It leaves enough surrounding space for bedside tables and walking areas, which is important for both comfort and aesthetics (designers suggest leaving at least 60 cm around the bed for movement).
- Considerations: If you have children or pets frequently joining you, or you simply love extra room, you might lean towards a king. But for most, a queen is the “just right” solution. It’s also typically easier to find bedding and bed frames for queen beds due to their popularity.
- Cost: Queen mattresses are a bit more expensive than doubles, but the increase in sleep space often justifies the price for couples. Many mattress-in-a-box brands (like Onebed, Koala, etc.) centre their lineup around queen size as the flagship, often with promotions (e.g., a discount or free pillows with a queen purchase).
Onebed highlight: Onebed’s Queen Mattress range showcases their models (Original, X 12”, Modular, etc.) in the popular queen size. Given it’s the most sought-after size in Australia, Onebed often includes the queen in bundle deals or has it readily in stock for quick delivery. If you’re upgrading from a double, Onebed’s queen could be a game-changer for your sleep.
King Bed – Ultimate Luxury for Couples (or Families!)
Stepping up to a King bed means enjoying an extra 30 cm of width beyond a queen. At 183 cm wide, a king mattress is like two singles pushed together, offering ample personal space for two sleepers. Length-wise, it’s the same 203 cm as a queen, which comfortably accommodates tall people.
- Why go King: If you have the bedroom space (and budget), a king is the pinnacle of comfort for couples. Each person gets about 91.5 cm of their own width – nearly the width of a twin bed each. This reduces disturbances if one person tosses and turns. Kings are also fantastic for family bed scenarios: if young kids or pets hop in on Sunday mornings, there’s room for everyone.
- Space & placement: Australian bed sizes don’t get larger than a standard king except for the super king (which is more niche). A king bed does need a large room – generally, your room should be at least 4m x 4m to comfortably fit a king bed with walking space around it. Ensure doorways, stairs, or hallways at home can accommodate a king mattress when delivered (most come rolled up if it’s memory foam or latex, but traditional spring mattresses in king can be a squeeze through narrow passages).
- Considerations: Bedding for king beds (sheets, quilts, etc.) will be a bit pricier than queen, and you’ll need larger accessories like a king-size headboard or base. Kings also weigh more, so if you move homes frequently, keep in mind the logistics.
- Couples’ tip: Some couples opt for a “split king” – which is essentially two king single mattresses on a king frame. This allows each side to have a different firmness (for example, one partner could use a medium mattress, the other a firm). It’s also useful for adjustable bed bases where each half can raise/lower independently.
Onebed insight: Onebed’s King Mattress lineup provides their top models in king size. One unique offering is Onebed’s Modular mattress, which effectively comes as a split king with interchangeable layers. This modular approach (with brands like Onebed offering modular options) means couples can customize each side of the bed or even separate the halves when needed – combining the luxury of a king with the flexibility of two mattresses.
Super King – Extra-Wide Comfort (for those with Space)
The Super King is less common but worth a mention. It’s essentially square – a full 203 cm both in width and length. This is a size for serious comfort seekers (or perhaps very tall individuals who also want extra width).
- Usage: Super kings are typically found in high-end hotels or luxury homes. If you have a huge master bedroom, a super king can anchor the space and make a bold statement. It’s the ultimate family bed – theoretically, it could sleep two adults and two small children side by side.
- Drawbacks: This size is massive. You need significant space not just for the bed, but also to maneuver around it. Finding bedding or even a bed frame can be trickier, as not every retailer stocks super king accessories. The weight and difficulty of moving a super king mattress are also considerations.
Mattress and Bed Height: Why Profile Matters
When shopping for a new bed, people often focus on length and width, but mattress height (thickness) and overall bed height (mattress + base) also play a key role in comfort, accessibility, and style. Here’s what to consider regarding bed height:
- Standard vs. Low-Profile Mattresses: Most mattresses today range from about 20 cm on the low end (often foam mattresses like some bed-in-a-box models) to 30 cm or more on the higher end (luxury hybrids or pillow-tops). A low-profile mattress (say 20–25 cm thick) can make a bed frame sit lower, which might be ideal for kids or shorter individuals who find it easier to get in and out of a bed that’s not too tall. It also gives a sleek, modern look.
- Thick Mattresses & Pillow-tops: Taller mattresses (30 cm and up) can feel more luxurious and often have multiple layers for plush comfort. They raise the sleeping surface, which some people (especially taller individuals) prefer because it’s akin to sitting on a chair when getting in or out of bed. However, thick mattresses can make the bed quite high off the ground if paired with a tall base – possibly an issue for those with limited mobility or for very short users whose feet might dangle when sitting on the edge.
- Bed Base Height: Don’t forget the base or bed frame contributes to overall height. A platform bed with slats might only add a few centimeters, whereas an ensemble base or box spring could add 20–30 cm. An adjustable bed frame also adds height (and often has adjustable leg heights; for example, Onebed’s adjustable frame offers 7.5cm, 15cm, 22.5cm, or 30cm leg heights).
- Aesthetic & Bedroom Style: Low beds (closer to the ground) create a modern, minimalist vibe and can make a room feel taller. High beds (mattress tops sitting 70 cm or more off the ground) give a classic, luxurious appearance – think of those grand beds in old movies you hop up into. Consider your bedroom’s style: a tall mattress with a thick ensemble base can look majestic, while a low-profile mattress on a simple frame gives contemporary simplicity.
- Onebed’s Height Options: As an example, Onebed’s different models have varying heights. The Onebed Original is around 25 cm, the Onebed X 12” is 30 and the Modular mattress is about 35 cm thick. Onebed’s modular design even allows adding or swapping layers, effectively letting customers adjust the height and feel.
Tip: When you find a mattress you like, look at the “height” or “thickness” spec. Then consider how high you want your bed to be. If you have a bed frame that sits 30 cm off the ground and you add a 30 cm mattress, the bed top will be 60 cm high. Try sitting on a chair of similar height to see if that feels comfortable for you. Older folks or those with knee issues might prefer a bed around 50-55 cm high (easy to sit and stand), whereas others might love the look of a towering bed or the sleekness of a low one.
In summary, mattress height affects comfort, accessibility, and style: lower beds are easier to access and modern-looking, taller beds can feel plush and traditional.
Choosing the Right Size: Key Takeaways and Tips
Now that we’ve covered Australian bed sizes from single through super king, plus talked about height, how do you decide which is right for you? Keep these tips in mind:
- Measure Your Space: Before buying, measure your bedroom. Allow at least 60 cm of space around the bed for walking (this includes space for bedside tables). A bed that just fits wall-to-wall will make the room feel cramped and can be a safety hazard at night.
- Consider Who’s Using It: Is it for a child, a teenager, a single adult, or a couple? For kids, a single or king single is usually fine. For a growing teen, consider a king single or double. Couples generally should start at queen for everyday comfort, unless room size dictates a double. If you or your partner are tall, make sure the 203 cm length of a queen/king covers you – if not, a super king (or a California King from overseas) might be needed.
- Sleeping Habits: If you’re a restless sleeper or you and your partner like more personal space, bigger is better. A larger mattress can minimize disturbances. Also, think about your sleep positions: side sleepers often sprawl more than back sleepers, so they may benefit from the extra width of a king.
- Future Needs: Buying a mattress is an investment (they last ~7-10 years on average). Plan for the future. Are you expecting a child who might crawl into bed with you? Do you have a pet that hogs the foot of the bed? It might be worth sizing up.
- Bed Base/Frame Compatibility: Ensure you have (or can get) a bed frame that matches the mattress size. Using an undersized frame is unsafe, and an oversized frame will leave gaps. Most frames are named by size (Single frame for a single mattress, etc.). If you’re upgrading from a double to a queen, your old double frame won’t fit!
- Accessibility & Style (Height): Think about how high you want the bed to sit. As discussed, mattress and frame height combined determine if you climb up into bed or kneel down to it. There’s no “right” height – just what’s right for you.
Frequently Asked Questions
What’s the most popular mattress size in Australia?
The Queen size is by far the most popular choice for Australian couples and is considered the standard size for master bedrooms.
Can two adults sleep comfortably on a Double mattress?
While it’s possible, a Double gives each person just 69 cm of width (less than a Single bed). For most couples, a Queen or King offers a more comfortable sleep experience.
What’s the difference between a King Single and a Double?
A King Single (107 cm × 203 cm) is narrower but longer than a Double (138 cm × 188 cm). King Singles are better for tall individuals sleeping alone, while Doubles offer more width but less length.
Will my sheets from another brand fit my Onebed mattress?
Yes! Onebed mattresses follow standard Australian dimensions, so any sheets marketed for Australian bed sizes will fit perfectly. However, do consider the mattress height (25 cm, 30 cm, or 35 cm) when purchasing fitted sheets to ensure proper fit.
I’m tall (over 6 feet/183 cm) – which size should I choose?
We recommend at least a King Single, Queen, or King, as these are all 203 cm long, giving you extra room to stretch out.
How does mattress height affect my choice of bed frame?
The combined height of your mattress and bed frame will determine how high you sleep off the ground. For the 35 cm Onebed Modular, a lower profile bed frame might be more comfortable, while the 25 cm Onebed Original might pair well with a taller frame.
Do I need to consider mattress weight when choosing a size?
Larger mattresses are heavier and may be more difficult to move. If you relocate frequently, consider this factor when choosing between sizes.
Making Your Final Decision
Choosing the right bed isn’t just about length and width – it’s about creating your ideal sleep environment. Australian mattress sizes give you plenty of options to get it just right. From a compact single bed size for a child’s room to a sprawling king size mattress for a master bedroom, the goal is to match the mattress to your needs and space.
When choosing your perfect Onebed mattress size, consider:
- Who will be using the bed: Solo, couple, family, pets?
- Your room dimensions: Measure your space carefully.
- Future needs: Planning to move? Relationship status changing?
- Budget considerations: Larger sizes cost more but may be worth the investment.
- Sleep style: Do you sprawl out or sleep in a compact position?
- Mattress height preference: 25 cm, 30 cm, or 35 cm to suit your comfort and aesthetic needs.
With this guide, you’re equipped to compare bed measurements and make an informed choice. For example, knowing the dimensions of a double bed (and how a double bed size Australia might differ slightly from elsewhere) can guide you if you’re furnishing a guest room or deciding between a double and queen for a smaller home. Likewise, understanding the size of a queen mattress Australia offers (153 x 203 cm) confirms why it’s the go-to for many couples.
