In the double bed vs queen bed comparison, Double beds measure 138 x 188 cm, while queen beds stretch to 153 x 203 cm, adding 15 cm to both the width and the length.
That extra room suits couples, taller sleepers and anyone who shares the bed with kids or pets. Solo sleepers, teenagers and guest rooms get plenty of space from a double, and it fits smaller bedrooms more easily.
Key Takeaways
- The double bed vs queen bed decision comes down to 15 cm, with queens at 153 x 203 cm and doubles at 138 x 188 cm.
- Couples, restless sleepers, taller sleepers and families benefit most from a queen, while solo sleepers, teenagers and guests get plenty of room from a double.
- Room size matters too, so measure the bedroom, leave 60 to 80 cm of clear space around the bed, then match sheets and frames to the mattress size.
The sections below settle the double vs queen choice by sleeper, room size and bedding. For the bigger picture on mattress type, firmness and budget, our how to choose a mattress guide covers the rest.
Size Difference Between Double and Queen Beds
Queens gain 15 cm in width, 15 cm in length and about 20% more sleeping surface than doubles.
Every Ecosa double mattress and queen mattress follows these standard Australian sizes.

In millimetres, doubles come to 1380 x 1880 mm and queens to 1530 x 2030 mm. Our Australian mattress size guide lists every other size too.
What Is a Double Bed?
A double bed is 138 x 188 cm, which puts it between a king single and a queen in width. It’s the same 188 cm length as a single, but 46 cm wider.
Our Single vs Double Bed guide covers that jump in more detail.
Double Bed Pros and Cons
Footprint and bedding flexibility favour the double, while shared nights and future growth work against it.
| Pros | Cons |
| Fits smaller bedrooms alongside bedside tables and a wardrobe. | Each adult gets just 69 cm when two share, which can feel snug for restless or hot sleepers. |
| Takes either a double or queen quilt, which keeps bedding choices flexible. | Outgrowing the size later means replacing the mattress, and usually the frame and fitted sheets too. |
| Comes in a low-profile Ecosa Kids version (13 cm high) for children aged 2 to 12. |
Who Should Get a Double Bed?
- Solo sleepers get 46 cm more width than a single, which suits starfish sleepers and anyone who rolls over often.
- Teenagers moving up from a single get a size that carries them into adulthood, though tall teens may want the 203 cm length of a king single or queen.
- Overnight guests fit comfortably on a double, whether one adult visits or a couple stays for a night or two.
- Couples who prefer sleeping close enjoy the cosier width, especially in smaller bedrooms.
What Is a Queen Bed?
A queen bed is 153 x 203 cm, which puts it between a double and a king. It’s the same 203 cm length as a king, which adds 30 cm of width.
Our Queen or King Size Bed guide covers that step up.
Queen Bed Pros and Cons
Room for two, extra length and years of use favour the queen, while floor space, per-person width and guest-room use count against it.
| Pros | Cons |
| Sleeps two adults comfortably side by side. | Takes up more of the bedroom, so smaller rooms can feel crowded. |
| Measures 203 cm long, which suits taller sleepers. | Couples wanting single-bed width each may prefer a king, which is 183 cm wide. |
| Suits a solo sleeper now and a couple later, so upsizing rarely comes up. | Extra size can go unused in a guest room that hosts one visitor at a time. |
Who Should Get a Queen Bed?
- Couples can lie close and still have space to shift around.
- Restless sleepers get extra width for elbows and knees to wander before reaching a partner.
- Families get room for the odd child or dog who climbs in on a stormy night or lazy Sunday.
- Taller sleepers gain 15 cm of length over a double, which keeps feet on the mattress instead of dangling over the end.

Will a Queen Bed Fit Your Bedroom?
A queen bed fits comfortably in a bedroom of at least 3.2 x 3.2 m (10.24 m²), the minimum our size guide recommends. That leaves room to walk around the bed and add bedside tables or a wardrobe. Rooms closer to 3 x 3 m (9 m²), our double minimum, suit a double instead.
In a 3.2 x 3.2 m room, a queen mattress centred against one wall leaves about 84 cm on each side and 117 cm at the foot. Bed frames often extend beyond the mattress through rails, headboards and storage bases, so measure with the frame’s listed size.
Try these four checks before you buy.
- Measure the room wall to wall, then mark the frame’s outline on the floor with masking tape.
- Aim for 60 to 80 cm of clear space on each side of the bed and at the foot.
- Check that the bedroom door and wardrobe doors can still swing open.
- Note where the power points sit, so lamps and chargers stay within reach.

Bedding and Bed Frames for Each Size
Fitted sheets and frames follow your mattress size, while quilts and covers can size up for extra drape.
Bedding for Double and Queen Beds
Our bamboo fitted sheets and quilt covers come in double and queen sizes. Fitted sheets measure 138 x 193 cm for a double and 153 x 203 cm for a queen. Quilt covers measure 180 x 210 cm for a double and 210 x 210 cm for a queen.

These essentials come in both sizes.
