Ever bought a new quilt cover, only to find it looks skimpy and barely drapes over the sides of your bed? You're not alone. Nailing the right measurements of a double bed quilt cover is the secret to a beautifully made bed. In Australia, the standard size is 180cm x 210cm. This is your starting point, but getting that perfect, plush look often means digging a little deeper into how that size works with your specific mattress.
Why Quilt Cover Size Matters
A well-fitting quilt cover does more than just look good; it keeps your quilt insert from bunching up and provides an elegant drape over the sides. The goal is a balanced overhang that feels cosy but doesn’t drag on the floor.
A key factor is your mattress depth. A deep, pillow-top mattress can "steal" width from your quilt cover, making a standard double size feel too short. In fact, a 2022 survey found that over 60% of consumers reported dissatisfaction with bedding fit due to not considering mattress height.
We'll show you exactly how to measure your bed for a flawless fit, ensuring you choose a size that drapes perfectly every time. For a full overview, see our comprehensive guide to Australian bed sizes.
How to Get the Perfect Quilt Cover Fit
Before buying new bedding, taking a moment to measure your quilt and mattress is the best way to achieve that polished, hotel-like finish. The right measurements of a double bed quilt cover depend on how it fits your specific quilt and drapes over your mattress. This simple step saves you from the frustration of a cover that’s too short or a quilt that gets lost inside.
Actionable Step 1: Measure Your Quilt Insert
First, measure your quilt (or duvet insert). Lay it flat on your bed or the floor, smoothing out any wrinkles to get an accurate reading.
- Measure the Width: Pull your tape measure from the left edge straight across to the right edge.
- Measure the Length: Do the same from the top edge down to the bottom edge.
Write these numbers down. Ideally, your quilt cover should be the exact same size as your insert. A standard Australian double quilt is 180cm x 210cm.
Actionable Step 2: Measure Your Mattress for Overhang
Next, measure your mattress to determine how much "overhang" you want—the part that drapes elegantly over the sides.
- Width and Length: A standard Australian double mattress is 138cm x 188cm. Measure yours to be sure.
- Depth (Height): This is crucial. Measure the height of your mattress from bottom to top. Pillow-top mattresses can be 30cm to 40cm deep, which dramatically affects fit.
Real-World Example: Let's say your mattress is 138cm wide with a 35cm depth. To cover the mattress sides, you need a quilt width of at least 208cm (138 + 35 + 35). This quick calculation shows why a standard 180cm double quilt can look too short and why upsizing is often a brilliant idea.

Comparing International Double Bedding Dimensions
Ever bought bedding online from overseas, only to find it doesn't fit? It's a common problem. What one country calls a 'double' can be a completely different size somewhere else. Understanding these differences helps you shop with confidence.
Why Global Sizes Differ
To get the perfect fit, you need to know the standard measurements of a double bed quilt cover in different regions. An Australian double is 180cm x 210cm, but a UK double is a square 200cm x 200cm, and a US 'Full' is wider again. These variations determine how much drape you get.
For example, an Aussie quilt cover on a US bed might leave the mattress sides exposed. A UK cover on an Aussie bed will have more width but might feel short at the end.
As you can see, mattress depth plays a vital role in finding the right fit. For more details on local sizing, check out our mattress size comparison guide.
International Size Conversion Chart
This quick-reference table breaks down typical sizes for double beds across key regions.
| Region | Mattress Size (cm) | Standard Quilt Cover Size (cm) | Notes on Fit |
|---|---|---|---|
| Australia | 138 x 188 cm | 180 x 210 cm | Designed for a standard overhang on typical Aussie mattresses. |
| United Kingdom | 135 x 190 cm | 200 x 200 cm | Wider but shorter, offering generous side drape but less foot coverage. |
| United States (Full) | 137 x 191 cm | Approx. 203 x 218 cm | Wider and longer, creating a lush, oversized feel on an Aussie double. |
The key takeaway is to always check the specific dimensions listed by the retailer, as sizes can even vary between brands.
Why Upsizing to a Queen Cover Creates a Better Look
One of the best styling secrets is to choose a quilt cover one size larger than your bed. For a double bed, this means opting for a queen size. It’s a simple switch that instantly gives your bedroom a luxurious, hotel-like feel.
The logic is all about the drape. A queen cover is 210cm wide, giving you an extra 30cm compared to a double (180cm wide). This generous overhang conceals the mattress and base for a seamless look. Many professional stylists recommend this, as seen on this size chart from leading Australian retailers.
The Visual Impact of Upsizing
Let's see how this works with a standard double mattress (138cm wide) with a modern 35cm depth.
-
Double Cover (180cm): You get just 21cm of overhang on each side. This barely covers the mattress, often leaving the bed base exposed.
-
Queen Cover (210cm): You get a much more generous 36cm of overhang on each side. This drapes effortlessly over the deep mattress, creating the fuller look you see in magazines.
This simple 'upsize' transforms your bed into a sophisticated centrepiece. Just remember to upsize your quilt insert too! When exploring materials, discover the benefits of a bamboo cotton quilt cover.
How Mattress Depth Affects Your Quilt Cover Choice
If your new quilt cover looks strangely short, your mattress depth is likely the culprit. This is one of the most overlooked factors when considering the measurements of a double bed quilt cover.
Modern mattresses with pillow tops and extra comfort layers are much deeper than older styles, often reaching 35-40cm. This extra height "uses up" the quilt cover's width, reducing the side drape.
Quick Calculation for Minimum Width
Use this simple formula to find the minimum width your quilt cover needs to be: Mattress Width + (Mattress Depth x 2) = Minimum Quilt Cover Width
This calculation tells you the width needed to reach the bottom edge of your mattress on both sides. For a truly elegant drape, add another 15-20cm to the final number.
A Real-World Example
Let's apply this to a standard double mattress (138cm wide) with a plush 35cm pillow top.
- Calculation: 138cm + (35cm x 2) = 208cm
You need a quilt cover at least 208cm wide. A standard double cover (180cm) would leave 14cm of mattress exposed on each side. This is precisely why upsizing to a Queen cover (210cm) is such a popular choice.
Pro Tip: A deep mattress also means standard fitted sheets may not fit. If yours is over 35cm deep, look into extra deep fitted bed sheets for a snug, secure fit.
Material Shrinkage and Fabric Care
Getting the measurements right is just the start. The fabric you choose affects how it fits, especially after washing. Natural fibres like cotton, linen, and bamboo are soft and breathable but tend to shrink slightly.
A quality quilt cover might shrink by 2-5% after the first wash. On a 180cm wide cover, that’s a loss of 3.5cm to 9cm. Reputable brands often account for this by cutting fabric slightly larger, so it settles to the perfect size.
How to Minimise Shrinkage
Managing shrinkage is simple with the right care routine. Always follow the instructions on the care label.
- Use Cold Water: Wash natural fabrics on a cold, gentle cycle to prevent fibres from tightening.
- Avoid High Heat: The intense heat of a tumble dryer is the main cause of shrinkage. Line-dry your cover in the shade to preserve its size, shape, and colour.
- Choose Quality: Higher-quality materials are less prone to excessive shrinkage. For another premium option, explore the benefits of using French linen for bedding.

Your Quilt Cover Sizing Questions Answered
Here are answers to the most common questions about double bed quilt cover measurements.
Can I Use a Queen Quilt Cover on a Double Bed?
Yes, absolutely! This is a favourite styling trick among interior designers. A Queen cover (210cm x 210cm) gives you an extra 30cm in width compared to a Double (180cm x 210cm). This extra fabric creates a luxurious drape that conceals a deep mattress or bed base, giving your bedroom a plush, hotel-inspired look.
What’s the Difference Between a Double and a Full Size Quilt Cover?
This often causes confusion. In Australia, we use the term ‘Double’. In the US, the equivalent is called a ‘Full’. While mattress sizes are similar, the quilt covers are not. An Australian Double quilt cover is 180cm x 210cm, whereas a US Full is typically wider and longer (around 201cm x 218cm). Always check the exact dimensions before buying internationally.
Should My Quilt Insert Match My Quilt Cover Size Exactly?
Yes, for a perfect fit, your quilt insert and cover should be the same size. A Double quilt insert fits perfectly inside a Double cover, preventing it from shifting. If you upgrade to a Queen cover for your Double bed, you must also use a Queen size quilt insert (210cm x 210cm) to achieve that full, lofty look.
