Super King Doona Measurements Australia 2025: The Ultimate Guide

Summary

What are the standard Super King doona measurements in Australia in 2025, and which size should you choose for a King or Super King bed?

 

In Australia, the standard Super King doona size is 270cm x 240cm, giving you generous overhang and a more luxurious, hotel-style drape. For a King bed, sizing up to a Super King doona helps prevent cold drafts and eliminates cover-tugging, while a Super King mattress should always pair with a matching Super King doona for full coverage. If you want a cooler, more comfortable sleep setup, pair your doona with breathable bamboo bedding and deep-wall protectors designed for Australia’s warm climate.

You’ve invested in a luxurious King or Super King bed, the centerpiece of your sleep sanctuary. Now comes the crucial finishing touch: the doona. But navigating the world of bedding sizes can be surprisingly confusing. You want that plush, inviting look with plenty of overhang, but what size doona do you actually need? Is a King doona big enough for a King bed? Or should you size up to a Super King?

 

This guide will clarify everything you need to know about Super King doona measurements in Australia, helping you choose the perfect size for a comfortable and beautifully dressed bed.

Understanding Australian Bedding Sizes: Doona vs. Bed

The first step is to understand that doona sizes do not match mattress sizes exactly. A doona is designed to be larger than the mattress to provide adequate coverage and overhang on the sides and bottom of the bed. This overhang is what keeps you covered when you move around at night and creates that cozy, enveloped feeling.

 

Here are the standard mattress dimensions in Australia for comparison:

  • King Mattress: 183cm x 203cm
  • Super King Mattress: 203cm x 203cm

What are the Standard Super King Doona Measurements in Australia?

The standard measurement for a Super King doona in Australia is 270cm x 240cm.

Let’s break that down:

  • Width: 270cm
  • Length: 240cm

It’s important to note that there can be slight variations between brands (e.g., 275cm x 245cm), but 270cm x 240cm is the industry standard that most Australian retailers adhere to.

Should I Use a Super King Doona on a King Bed?

This is one of the most common questions, and for many people, the answer is a resounding yes! While a standard King doona (245cm x 210cm) is designed for a King bed, many people find it doesn’t provide enough overhang, especially if you have a thick mattress or if you share the bed with a partner who tends to hog the covers.

 

Let’s compare the coverage:

On a King Bed (183cm wide)

King Doona (245cm wide)

Super King Doona (270cm wide)

Total Overhang

62 cm

87 cm

Overhang Per Side

31 cm

43.5cm

As you can see, using a Super King doona on a King bed gives you an extra 12.5cm of coverage on each side. This extra drape prevents drafts, stops the dreaded “cover tug-of-war” between partners, and creates a more luxurious, hotel-style look with the doona draping further down the sides of the bed.

Recommendation: If you have a King bed, especially a deep one with a pillow-top or mattress topper, we highly recommend sizing up to a Super King doona for optimal comfort and style.

Using a Super King Doona on a Super King Bed

If you have a true Super King mattress (203cm x 203cm), then a Super King doona (270cm x 240cm) is the correct size to use. Let’s look at the overhang:

  • Width: A 270cm wide doona on a 203cm wide bed gives you 67cm of total overhang, or 33.5cm per side.
  • Length: A 240cm long doona on a 203cm long bed gives you 37cm of overhang at the foot of the bed.

This provides ample coverage for even the largest of beds, ensuring you and your partner are completely covered all night long.

Choosing a Super King Doona Cover

Once you’ve chosen your Super King doona, you need a cover to match. A Super King doona cover will have the same dimensions as the doona itself: 270cm x 240cm.

 

Important: Do not try to squeeze a Super King doona into a King-sized cover. It will be far too tight, causing the doona to bunch up, feel lumpy, and lose its insulating properties (its “loft”). Always match your doona size to the same cover size.

Frequently Asked Questions

What is the difference between a Super King doona and a US King / Californian King doona?

Bedding sizes are not standardized internationally, which can cause a lot of confusion, especially when shopping online from overseas retailers. A US King size bed is wider and shorter than an Australian King. A Californian King is narrower and longer. Their duvet sizes are different from ours. Always buy your doona and covers from a reputable Australian retailer to ensure you get the correct standard Australian sizing.

My Super King doona seems to have different dimensions. Why?

While 270cm x 240cm is the standard, some brands may have slight variations. This is usually not a problem, as a few centimetres difference will not be noticeable. However, always check the dimensions on the packaging of both your doona and your doona cover to ensure a good fit.

Why is a Super King doona longer (240cm) than a King doona (210cm)?

The extra length is designed to accommodate the larger size of a Super King bed and also to provide more length to tuck in at the foot of the bed or to fold over at the top for a styled look, while still providing ample coverage for your body.

What if I can’t find Super King doona covers I like?

In the past, Super King was a less common size, and the range of covers was limited. However, with the growing popularity of sizing up doonas and the increasing sales of Super King beds, most major Australian bedding retailers now offer a wide and stylish range of Super King doona covers. You should have no trouble finding one to match your decor.
