Stuck choosing between a double bed size and queen bed size? Here’s the most important thing you need to know: a queen bed is 15cm wider and 15cm longer than a double. That extra space might seem small, but for couples or taller individuals, it’s the difference between a cramped, restless night and waking up refreshed. This guide cuts through the confusion to give you clear, practical advice on picking the perfect bed for your space and sleep style.
Making the right choice is a major investment in your sleep quality. With research from the Sleep Health Foundation showing that 45% of Australian adults feel they don't get enough sleep, optimising your bed size is a simple yet powerful step towards better rest.
Double vs. Queen Bed: The Key Differences at a Glance
For most Australians, the choice boils down to these two popular sizes. While they look similar, the size gap has a real impact on sleep quality, especially for couples. A double bed gives each person just 69cm of personal width—that's less than a standard single mattress! This often leads to sleep disruption when a partner moves.
In contrast, a queen offers a more comfortable 76.5cm per person, reducing the chances of being woken up.
Let's break down the key differences to help you decide.
Quick Comparison: Double vs. Queen Bed
This table provides a straightforward overview of Australian double and queen bed sizes.
| Feature | Double Bed | Queen Bed |
|---|---|---|
| Dimensions (AU) | 138cm x 188cm | 153cm x 203cm |
| Ideal For | Single sleepers, teens, guest rooms | Couples, taller individuals, master bedrooms |
| Minimum Room Size | 3.0m x 3.2m | 3.2m x 3.5m |
| Best Use Case | Maximising floor space in smaller rooms | Balancing comfort and space in standard rooms |
Key Takeaway: That 15cm difference in width and length is the most critical factor. For couples or anyone over 180cm, a queen is almost always the better choice, providing enough personal space and preventing feet from dangling off the end.
A double is a smart, practical option for smaller rooms or guest spaces. However, the queen remains the gold standard for shared sleeping comfort. If you think you might need even more room, our king vs queen size bed guide can help.
Understanding the Double Bed Size and Queen Bed Size in Australia
Getting the measurements right is the absolute first step. These dimensions determine if a bed will fit your room and whether your sheets will stay put all night. In the world of mattresses, every centimetre counts.
Knowing the official Australian figures saves you from costly mistakes, especially when buying online.
Australian Standard Dimensions
- Australian Double Bed: Measures 138 cm wide by 188 cm long.
- Australian Queen Bed: Measures 153 cm wide by 203 cm long.
A queen gives you an extra 15cm of width and a crucial 15cm of length. That added length is a game-changer for anyone over 180cm tall. For couples, the extra width provides enough elbow room to avoid feeling cramped.

Why Manufacturing Tolerance Matters
Ever bought a fitted sheet that was just a fraction too tight? That's likely due to manufacturing tolerance—a small, acceptable variation of a centimetre or two during production.
A mattress labelled 153cm wide might actually measure 152cm or 154cm. This is normal but can make a difference in how your sheets fit.
Well-designed fitted sheets account for this. Look for options with deep walls or generous elastic, which can easily accommodate slight variations and guarantee a snug fit every time.
The Impact on Your Bedding
Knowing these dimensions is the secret to a perfectly made bed. A fitted sheet that pings off a corner in the middle of the night isn't just annoying; it's a genuine disruption to your rest.
This is where thoughtful design comes in. For example, our Sienna Living bamboo sheet sets are made with a generous 40cm wall depth. This ensures they easily fit over standard mattresses, thicker pillow-top models, and even beds with an added mattress topper, taking any manufacturing tolerance in stride.
Choosing the Right Bed for Your Bedroom
The right bed choice can make your space feel balanced, while the wrong one creates a cluttered obstacle course. Your bed is the anchor of the room, and its footprint sets the tone for everything else.
Cluttered spaces can increase stress and disrupt sleep quality. Ensuring your bed doesn't overwhelm the room is a simple way to create a more restful environment. For expert help maximising your space, you might consider professional interior design services.
The Golden Rule of Bedroom Spacing
A simple rule of thumb is to leave at least 70cm of clearance around the sides and foot of your bed. This is the practical minimum you need to walk around comfortably without shuffling past furniture. This breathing room makes daily life easier, from making the bed to opening wardrobe doors.
Pro Tip: Use masking tape to outline the dimensions of a double (138cm x 188cm) and a queen (153cm x 203cm) on your floor. This simple trick helps you visualise the bed’s footprint and see exactly how much walking room you'll have left.
Real-World Scenarios: Double vs. Queen
Let's see how these bed sizes fit into common Australian bedrooms.
Scenario 1: The Compact Guest Room (3.0m x 3.5m)
- With a Double Bed: Centred against the 3.0m wall, a double bed leaves a comfortable 81cm of clearance on each side. This is plenty of space for guests to move around.
- With a Queen Bed: A queen shrinks that clearance to 73.5cm. It's workable, but the room will feel noticeably tighter. The double is the clear winner for keeping the room feeling open.
Scenario 2: The Standard Master Bedroom (4.0m x 4.5m)
- With a Double Bed: A double can look a bit lost in a spacious master bedroom, throwing the room's proportions off.
- With a Queen Bed: A queen is perfectly scaled for a room this size. It acts as a luxurious focal point while still leaving over 120cm of clearance on each side—more than enough room for bedside tables and a dresser.
Your Measurement Checklist
- Measure Room Dimensions: Get the exact length and width of your bedroom.
- Account for Furniture: Measure existing pieces and check how much space their doors and drawers need to open.
- Map It Out: Use the masking tape trick to mark the bed’s footprint on the floor.
- Check Your Pathways: Walk around the taped-off area. Is there at least 70cm on the most-used sides?
- Consider Your Lifestyle: Do you value more floor space or a bigger sleeping surface? If you're leaning towards an even larger bed, our article comparing the king vs queen size bed is a great next step.
A Practical Guide to Bedding and Accessories
The secret to a five-star sleep experience is nailing the bedding. The right sheets, quilt, and topper depend on one thing most people overlook: mattress depth.
Modern mattresses, especially plush pillow-top models, are getting thicker. A standard fitted sheet often doesn't have the wall depth to handle them, leading to a poor fit.
Why Mattress Depth Changes Everything
Mattress depth is how thick your mattress is. While 25-30 cm was once the norm, premium mattresses today often reach 35 cm or more. If your fitted sheet's pocket is too shallow, it stretches too tightly over the corners and will eventually pop off.
Real-World Example: Sarah bought a new 38cm deep pillow-top queen mattress. Her old queen sheets, made for a 30cm mattress, became a nightly battle as a corner would slip off every time she moved. The moment she switched to Sienna Living’s 40cm deep-walled bamboo sheets, the problem vanished. They fit over her mattress and topper with ease and stayed put.
Matching your bedding's depth to your mattress is as crucial as getting the length and width right.
Getting the Right Fit for Every Layer
Think of your bed as a system where every layer works in harmony. Getting the sizing right delivers a neat, inviting look and supreme comfort.
This quick reference will help you dress your double or queen bed perfectly.

| Mattress Topper | 138 x 188 cm | 153 x 203 cm | Should match the mattress dimensions exactly for even support. |
Of course, the feel of your bedding is just as important. If you're curious about different fabrics, this guide to custom blanket materials is a fantastic resource for comparing textures.
Quilt Sizing for the Perfect Drape
A correctly sized quilt drapes beautifully over the edges of the bed.
- For a Double Bed (138cm wide): A standard double quilt (180 cm x 210 cm) gives you 21 cm of overhang on each side.
- For a Queen Bed (153cm wide): A standard queen quilt (210 cm x 210 cm) provides a more generous drape of roughly 28.5 cm per side.
That extra overhang looks better and stops cold drafts from sneaking in. For more advice, see our article on choosing the perfect duvet size for a queen bed.
Double vs. Queen: How Australian Sizes Compare Around the World
Comparing a double bed size and queen bed size internationally is surprisingly complex. A "queen" in Australia isn’t the same as a "queen" in the US, and that small difference can lead to the big headache of a mattress or sheets that just don't fit.
Australian Bed Sizes vs. The World
The biggest mix-ups usually happen between Australian, UK, and US sizing. They often share names but have completely different dimensions.
- United States (US): A US ‘Full’ bed is slightly wider but shorter than an Australian Double. A US ‘Queen’ is wider and longer than ours, at about 152cm x 203cm.
- United Kingdom (UK): A UK ‘Double’ is slightly smaller than an Australian one. A UK ‘King’ measures 150cm x 200cm, making it narrower and shorter than an Australian Queen.
This is a crucial detail. A "King" quilt from a UK shop will be too small for your Aussie Queen bed. The lesson? Always check the dimensions in centimetres, not just the name.
The image below shows how different bedding items are meant to fit, highlighting why size matters.
For a deeper dive into how all Australian sizes stack up, our mattress size comparison guide gives you the full rundown.
Why This Matters in The Real World
Imagine Mark, an American moving to Sydney. He brings his US Queen sheets for his new Australian Queen mattress, only to discover they're too big and baggy. The US Queen bed they were made for is wider, so the fitted sheet bunches up and the flat sheet never stays tucked in.
This example points to one critical takeaway: always verify the exact measurements in centimetres (cm) before you buy. Relying on regional names alone is a surefire way to end up with something that doesn’t work.
A Situational Guide: Who Should Choose a Double or a Queen?
Picking the right bed is about fitting it to your life. The right mattress supports you day in and day out, whether you're a solo sleeper in a city apartment or a couple in a family home.
When a Double Bed is the Perfect Fit
A double bed is a master of efficiency, delivering comfort for one person without taking over the room.
- The Teenager's Retreat: A double gives teens the room they need to stretch out while fitting neatly into a standard bedroom.
- The Compact City Apartment: For solo sleepers in smaller urban apartments, a double provides comfort without sacrificing precious floor space.
- The Versatile Guest Room: A double is perfect for guest rooms. It’s welcoming for a single guest and fine for a couple on a short visit, leaving room for luggage.
Why a Queen Bed is the Popular Choice
The queen bed is Australia's most popular size because it nails the balance between comfort and a manageable footprint.
- The Couple's Sanctuary: For two adults, the extra 15 cm of width a queen offers is key to minimising partner disturbance.
- The Solo Sleeper Who Loves Space: If you toss and turn or share the bed with a pet, a queen is pure luxury.
- The Master Bedroom Focal Point: A queen bed has the perfect proportions to act as a visually pleasing centrepiece in a typical master bedroom.

Your Questions Answered
Here are answers to a few common questions about choosing between a double and a queen bed.
Can Two Adults Really Sleep Comfortably In A Double Bed?
Technically, yes, but it’s a tight squeeze. A double bed gives each person just 69cm of width—less space than a single bed. For most couples, the jump to a queen is a game-changer, with each person getting 76.5cm of space, which significantly reduces disturbances.
Is There A Big Price Difference Between A Double And A Queen?
A queen mattress and its bedding generally cost about 10-20% more than the double equivalent. However, most people find this small extra investment pays off in sleep quality and long-term comfort, making it a worthwhile upgrade.
How Do I Properly Measure My Room For A New Bed?
First, measure the room's length and width, noting doors, windows, and existing furniture. Then, use masking tape to outline the bed’s dimensions on the floor. This gives you a real feel for the space it will occupy and helps you see if you can maintain at least 70cm of walking room.
