Choosing a mattress size sounds like the easy part. Then you start measuring, and the questions pile up fast. Is a Queen actually big enough for two adults? Will a King fit once you allow for bedside tables? Why do the sheets you bought overseas never quite fit?
This guide covers every standard mattress size sold in Australia, in centimetres, along with the room space each one realistically needs. We've included the exact dimensions of our own mattresses too, so you can measure with real numbers rather than approximations.
Australian mattress sizes at a glance
These are the standard Australian bed sizes. Manufacturers vary by a centimetre or two, so always check the specific product before buying a base or bed frame.
| Size | Width × Length (cm) | Best suited to |
|---|---|---|
| Single | 92 × 188 | Children, small bedrooms, bunk beds |
| King Single | 107 × 203 | Teenagers, taller single sleepers, guest rooms |
| Double | 138 × 188 | One adult with room to spread out, or a tight-fit couple |
| Queen | 153 × 203 | Most Australian couples — the default choice |
| King | 183 × 203 | Couples wanting space, or those sharing with kids or pets |
| Super King | 203 × 203 | Large master bedrooms only |
Two things worth noticing in that table
Single and Double are the same length — 188cm. Anyone taller than about 180cm will find both of them short, regardless of how much width they add.
King Single, Queen, King and Super King are all 203cm long. That's why a King Single suits a tall teenager so well: it's a Single's width with a King's length, so they won't outgrow it.
Felice mattress dimensions
Here are the exact measurements of our mattresses, so you can plan around real figures rather than industry averages.
Felice Hybrid dimensions and pricing
The Felice Hybrid has a 29cm profile and comes in four sizes.
| Size | Dimensions | Price |
|---|---|---|
| Single | 90 × 190 × 29cm | $490 |
| King Single | 107 × 203 × 29cm | $590 |
| Queen | 150 × 200 × 29cm | $790 |
| King | 180 × 200 × 29cm | $990 |
Felice Green dimensions and pricing
The Felice Green has a deeper 34cm profile and is available in two sizes.
| Size | Dimensions | Price |
|---|---|---|
| Queen | 150 × 200 × 34cm | $990 |
| King | 180 × 200 × 34cm | $1,190 |
Why our Queen and King measure 150 × 200cm
You'll notice our Queen and King are 150 × 200cm and 180 × 200cm, rather than the 153 × 203cm quoted as the Australian standard. The difference is about 3cm in each direction — roughly the width of two fingers.
In practice, this affects one thing: fitted sheets. Australian Queen sheets are cut for 153 × 203cm, so on a Felice Queen they'll sit slightly loose rather than drum-tight. Most people never notice, particularly since our deeper 29cm and 34cm profiles take up the extra fabric in the skirt. But if you're the sort of person who irons their sheets, it's worth knowing before you order.
For bed frames and bases, the difference works in your favour. A mattress slightly under standard will always drop into a standard frame. It's the oversized ones that cause problems.
How much bedroom space each size actually needs
This is the part most size guides skip, and it's where people get caught out. A mattress that fits your room on paper can still make the room unusable.
The working rule: leave 60–75cm of walking space on any side of the bed you need to access, and at least 90cm in front of a wardrobe so the doors open properly.
Single — 92 × 188cm
Works in a room from about 2.1 × 2.7m. Fine for children's rooms and bunk setups, but plan to replace it once they hit their teens.
King Single — 107 × 203cm
Needs roughly 2.4 × 3m. The extra 15cm of length over a Single makes a genuine difference for a growing teenager, and it's the size we'd point most parents toward for a room that has to last a decade.
Double — 138 × 188cm
Around 2.7 × 3m. Worth being honest here: a Double gives each person in a couple about 69cm of width, which is narrower than a single bed each. It's a good size for one adult who likes room to move, and a compromise for two.
Queen — 153 × 203cm
Around 3 × 3.3m. This is where most Australian couples land, and for good reason. It's the balance point between personal space and a bedroom you can still walk around.
King — 183 × 203cm
Around 3.6 × 3.9m. Each person gets 91cm, about the width of a King Single each. If you share the bed with children in the early morning, or with a dog who has firm opinions about where he sleeps, this is the size that solves it.
Super King — 203 × 203cm
4 × 4.2m and up. Genuinely large master bedrooms only, and be aware that bedding in this size is harder to find and more expensive.
The masking tape test
Before you commit, mark the mattress footprint on your bedroom floor with masking tape and live with it for a day. Walk the route from the door to the wardrobe. Open the drawers. It takes five minutes, and it's more reliable than any calculation on a page.
Queen vs King: how to actually decide
This is the most common decision Australians face, and the honest answer is that it usually comes down to your room rather than your body.
When a Queen is the right call
Choose a Queen if your bedroom is under about 3.5m wide, you want bedside tables on both sides, or you and your partner sleep relatively still. It's also far easier to buy for — sheets, quilts and mattress protectors are cheapest and most widely stocked in Queen, and that difference adds up over the life of the bed.
When to size up to a King
Choose a King if one of you is a restless sleeper, you regularly have kids or pets in the bed, either of you is over about 185cm, or you simply have the floor space. The 30cm of extra width sounds modest, but it changes how a bed feels to share.
The cheaper fix most people miss
If the real complaint is a partner who steals the covers, a King quilt on a Queen bed solves it for a fraction of the cost of upsizing the whole bed. Try that before you assume you need a King.
And if the problem is one person waking the other when they turn over, size is only part of the answer — construction matters more. Our comparison of the Felice Green and Felice Hybrid covers how the two handle motion differently.
Australian sizes vs US and UK sizes
If you've bought bedding online from overseas and it didn't fit, this is why.
| Name | Australia | United States | United Kingdom |
|---|---|---|---|
| Single / Twin | 92 × 188cm | 99 × 191cm | 90 × 190cm |
| Double / Full | 138 × 188cm | 137 × 191cm | 135 × 190cm |
| Queen | 153 × 203cm | 152 × 203cm | 150 × 200cm |
| King | 183 × 203cm | 193 × 203cm | 150 × 200cm |
Why the King is the one that catches people out
An Australian King is 183cm wide. A US King is 193cm. A UK King is only 150cm — narrower than an Australian Queen. A "King" fitted sheet ordered from a British retailer will not fit an Australian King bed, and no amount of pulling will fix it.
Australian and US Queens are close enough that sheets usually work between them. For everything else, check the centimetres rather than trusting the name.
Will it fit through the door?
With a traditional mattress, this is a real problem. A Queen is 153cm wide and won't bend, which makes tight staircases, landings with a turn, and older Queenslander hallways genuinely difficult.
How a mattress in a box solves it
Both Felice mattresses are compressed, rolled, and shipped in a carton that one person can move through a standard doorway, up a stairwell, and around a corner. You unbox it on the bed base, and it expands in place.
If you live in an apartment, a terrace, or anywhere with a lift that has a shallow floor plate, this is worth more than it sounds. Details are in our shipping information, and our guide to buying a mattress online in Australia covers what to expect on delivery day.
Matching your mattress to your existing base
Size is only half of it. The base underneath affects both how the mattress feels and whether your warranty holds.
Slatted bases
Slats should sit no more than 7cm apart. Wider gaps let foam sag between them, which shows up as body impressions within a year or two. If your gaps are wider, a sheet of thin ply or a bunkie board over the slats fixes it cheaply.
Ensemble bases
Check that the surface is flat and firm. An old ensemble that has already dipped will telegraph that dip straight through a new mattress, and you'll blame the mattress.
Platform and adjustable bases
Slat-free platform bases are ideal for foam and hybrid mattresses — nothing further needed. For an adjustable base, check the mattress is rated to flex before buying.
Measure the inside of the frame
Measure your base's internal dimensions, not the outer edge. A frame is often 5–10cm wider on the outside than the space the mattress actually sits in, and that's the measurement that matters.
Don't forget the pillow
A well-sized mattress won't fix neck pain caused by the wrong pillow height. Pillow loft should match your sleeping position: side sleepers need the most height to fill the gap between shoulder and ear, back sleepers need medium, and stomach sleepers need very little.
Our Memory Foam Pillow is contoured for side and back sleepers, and it's the accessory most people add when upgrading a mattress. If you're dealing with morning stiffness, our guide to the best mattress for back pain in Australia covers how support and alignment work together.
Frequently asked questions
Is a Queen big enough for two adults?
For most couples, yes. A Queen gives each person about 76cm of width. It becomes tight if either partner is broad-shouldered, moves a lot in their sleep, or if children join you in the morning — in which case a King is the better long-term buy.
Are Australian mattress sizes the same as American?
Close but not identical. Queens are near enough that bedding usually works. Kings are not — an American King is 10cm wider than an Australian King. Always compare centimetres, not names.
What is a King Single and who is it for?
A King Single is 107 × 203cm — the width of a Single with the length of a King. It suits teenagers, tall adults sleeping alone, and guest rooms where you want comfort without giving up floor space.
How much bigger is a King than a Queen?
An Australian King is 30cm wider than a Queen. Both are 203cm long, so the difference is entirely width — about 15cm more per person.
Can I put a Queen mattress on a Double base?
No. A Queen is 15cm wider and 15cm longer than a Double. The mattress will overhang unsupported on all sides, which causes premature sagging and typically voids warranty cover.
Do I need a new base when I buy a new mattress?
Not necessarily. If your base is flat, structurally sound, and has slats no more than 7cm apart, it will do the job. Replace it if it dips, creaks under load, or has broken slats.
What size mattress does Felice offer?
The Felice Hybrid comes in Single, King Single, Queen and King. The Felice Green comes in Queen and King. You can see both, with current pricing, on our products page.
Choosing your size
If you're buying for one adult, a King Single is almost always the better call over a Single — the extra length costs little and lasts far longer. If you're buying for a couple, start with a Queen and only move up to a King if your room genuinely accommodates it and one of you is a restless sleeper.
Once you've settled on size, the next decision is construction. Our guide to latex, memory foam and hybrid mattresses walks through the differences, and every Felice mattress is backed by a 10-year warranty.
Standard Australian dimensions listed in this guide are industry conventions and vary slightly between manufacturers. Felice product dimensions and pricing are correct as at September 2026. Always confirm the specific measurements of your chosen mattress and base before purchasing.
