Searching for "king size bed dimensions cm"? You want a straight, clear answer without the fluff. Let's get right to it: in New Zealand, a standard king size mattress measures 168 cm wide and 203 cm long. It’s a generous size that gives couples plenty of elbow room, making it a favourite choice for anyone upgrading from a Queen.
Your Quick Guide to NZ King Bed Dimensions
Shopping for a new bed can get confusing pretty quickly with all the different names and numbers floating around. This guide is designed to cut through that noise and give you the essential figures you need upfront. Knowing the standard king size dimensions in cm is the crucial first step to making sure your new bed not only fits your bedroom but also gives you the luxurious comfort you're looking for.
Here in New Zealand, you'll find that major retailers work to a consistent standard. The NZ King bed dimension is reliably 168 cm wide × 203 cm long. This consistency makes shopping much easier, but it's good to be aware that our local sizes can differ from what you might find overseas.
To help put the NZ King into context, let's see how it stacks up against the other popular sizes you'll come across.
NZ Standard Bed Sizes At A Glance (cm)
This table gives you a quick comparison of standard New Zealand mattress dimensions in centimetres. It's a handy way to visualise exactly how much space each size offers.
| Size Name | Width (cm) | Length (cm) |
|---|---|---|
| Queen | 153 cm | 203 cm |
| King | 168 cm | 203 cm |
| Super King | 183 cm | 203 cm |
As you can see, the jump from a Queen to a King gives you a significant 15 cm of extra width to stretch out, all while keeping the same length.

Getting to Know the NZ King Bed Family
When you start shopping for a bigger bed, you'll soon find that "King" isn't a single, straightforward size. Here in New Zealand, it's more like a family of options, each tailored for different needs when it comes to space and comfort. Getting the king size bed dimensions in cm straight for each variation is the key to choosing wisely for your home and lifestyle.
The three main players in the NZ King family are the standard King, the Super King, and the California King. Each one offers a specific advantage, whether that's extra width for partners who toss and turn or more length for the vertically blessed. Nailing this choice from the start helps you avoid the classic mistake of buying a bed that just doesn't feel right for you or your bedroom.
NZ King: The Standard Choice
For anyone upgrading from a Queen, the standard NZ King is the most popular and logical next step.
- Dimensions: 168 cm wide x 203 cm long
- Best For: Couples who need a noticeable upgrade in personal space but don't want to go for the absolute widest bed on the market. It gives two adults plenty of room to sleep without getting in each other's way.
This size really hits the sweet spot. It fits comfortably into most master bedrooms while still delivering that luxurious, spacious feel you're looking for.
Super King: For Maximum Width
If what you're really after is the most generous sleeping surface you can get, the Super King is the undisputed champion of width.
- Dimensions: 183 cm wide x 203 cm long
- Best For: Families who love a weekend morning cuddle, couples who treasure their personal space, or anyone whose furry friends have claimed a spot on the bed. That extra 15 cm of width compared to a standard King makes a world of difference.
The sheer roominess of a Super King can be a game-changer for sleep quality, especially if you're a light sleeper easily disturbed by a partner's movements. It creates a truly expansive and peaceful sleep environment.
California King: For Taller Sleepers
A little bit different from the others, the California King trades a bit of width for some serious extra length.
- Dimensions: 168 cm wide x 213 cm long
- Best For: Anyone over 183 cm (that's 6 feet) tall who is tired of their feet dangling off the end of a standard bed. It gives up some width but adds a crucial 10 cm in length, making sure taller people can finally stretch out properly.
While these King options offer plenty of room, it's always good to see how they stack up against smaller sizes. For smaller rooms or single sleepers, you can find a complete breakdown in our guide to King Single dimensions.
Comparing King vs Queen Bed Dimensions
Choosing between a King and a Queen is probably one of the most common dilemmas Kiwis face when buying a new bed. Both are great options, but the real difference comes down to the dimensions and how that translates to your comfort and your bedroom space.
A standard NZ Queen is 153 cm wide by 203 cm long. The King keeps that same generous length but bumps the width up to 168 cm. So, you're getting an extra 15 cm across the bed with a King. It might not seem like a massive difference on paper, but in the real world, that extra space can be the key to a better night's sleep, especially for couples.
For a closer look at the Queen size specifically, check out our detailed guide on what size a Queen mattress is.
What That Extra 15 cm Really Means
That seemingly small 15 cm of extra width you get with a King bed is a genuine game-changer. On a Queen, each person gets about 76 cm of personal space. With a King, that jumps up to 84 cm each. This extra room drastically cuts down on partner disturbance.
If you or your partner are restless sleepers, that buffer zone means you’re far less likely to feel every toss and turn. It’s often the difference between waking up grumpy and waking up refreshed.
This isn't just about couples, either. That bit of extra surface area is perfect if a small child or a pet likes to jump in for morning cuddles without everyone feeling squashed.
Moving from a Queen to a King gives you about 10%–11% more sleeping width. It’s a modest percentage, but the impact on sleep quality is anything but small, giving each person their own undisputed territory to sleep soundly.
According to figures from New Zealand retailers, this extra width adds up to around 1,650 cm² more total sleep area. This is precisely why the King is so often recommended for couples prioritising personal comfort. While the Queen is a bestseller for its versatility, the King is the undisputed champion for partners who want to maximise their own sleeping space.
How NZ King Dimensions Compare Internationally
It’s a classic mistake to assume a "King" bed is the same size everywhere. When you’re browsing online stores or looking at imported bed frames, you'll quickly discover that what we call a King in New Zealand is quite different from a King in the UK, Australia, or the US.
Getting this wrong can be a costly exercise. A bed frame from overseas might not fit your mattress, or that fancy duvet set you ordered could be comically large or frustratingly small. Let's break down exactly how our local sizes stack up on the world stage to make sure you get it right.
This infographic is a great starting point, showing the 15 cm jump in width you get when moving from a standard NZ Queen to our NZ King.
That extra space is a big reason so many Kiwis choose to upgrade. But as you'll see, that 168 cm width is unique to us.
A Global Comparison of King Bed Sizes
To put things in perspective, here’s a clear comparison of standard King bed dimensions from New Zealand and other major markets. The differences are pretty significant.
International King Size Mattress Dimensions Comparison (cm)
| Region | Size Name | Width (cm) | Length (cm) |
|---|---|---|---|
| New Zealand | King | 168 cm | 203 cm |
| Australia | King | 183 cm | 203 cm |
| United Kingdom | King | 150 cm | 200 cm |
| United States | King | 193 cm | 203 cm |
As the table shows, the name "King" is used for four very different mattress sizes. An Australian King is actually the same size as our NZ Super King, while a UK King is smaller than our King in both width and length—it's closer to an NZ Queen.
The main takeaway here is simple: international bedding is almost never a direct fit for an NZ King bed. A fitted sheet for a UK King would be far too tight, and a duvet from a US King would completely swamp the bed.
Practical Implications for Shoppers
These measurement differences have very real consequences. Picture this: you order a beautiful oak bed frame from a UK retailer, only to find your NZ King mattress hangs over the edges because the frame is 18 cm too narrow.
Here are a few key points to keep in mind when shopping:
- Australian Bedding: An Aussie King mattress is 15 cm wider than an NZ King. This means any Australian King fitted sheets or mattress protectors will be loose and baggy.
- UK Sizing: A UK King is significantly smaller, measuring 18 cm narrower and 3 cm shorter than an NZ King. No UK King bedding will fit your mattress.
- US Sizing: The standard US King is a massive 25 cm wider than our NZ King. While a generous flat sheet might be okay, any fitted items would be completely unusable.
The bottom line? Always, always double-check the dimensions in centimetres before you buy any international bedding or furniture. That extra minute of checking can save you a lot of money and frustration. This is especially true for larger beds; for example, finding the right accessories is critical, and it's worth learning about options like a Super King mattress protector that is made specifically for New Zealand sizing.
How To Measure Your Room For A King Bed
Before you fall in love with a king bed, let’s make sure it will actually fit your space. It's an easy step to overlook, but a bed that's too big can quickly turn a master bedroom into a cramped obstacle course, making your luxury purchase a daily frustration. Measuring properly isn't just about the bed's footprint; it's about how you'll move around it, what other furniture you need, and even how you'll get it through the door.
Start by measuring the total length and width of your bedroom. Then, try this simple trick: use masking tape on the floor to mark out the standard NZ king size bed dimensions of 168 cm x 203 cm. This gives you a fantastic visual guide to how much floor space the bed will really take up.
This step helps you see the bed's true scale within the room and can save you from a very expensive mistake. If you map it out and realise a king is just too tight, it might be worth exploring the smaller double bed size in NZ as a practical alternative.
Planning for Clearance and Access
A bed needs breathing room. You have to factor in clearance space around it to keep your bedroom functional and comfortable. Without it, you'll be squeezing past furniture, struggling to make the bed, and unable to open drawers properly.
Run through this quick checklist to ensure a smooth, hassle-free setup:
- Walkway Clearance: Aim for at least 70-75 cm of clear space on at least two sides of the bed. This is the minimum you need to walk around comfortably.
- Furniture Function: Double-check that you can still fully open wardrobe doors, drawers on your chests and bedside tables, and any windows.
- Access Route: This is a big one. Measure the width and height of all the doorways, hallways, and stairwells on the delivery path. Don't forget to look out for any tight corners or low-hanging lights.
Just a heads-up: the mattress dimensions are only half the story. The bed frame itself, particularly if it has a chunky headboard or footboard, can easily add an extra 5-15 cm to the total length and width. Always check the frame's final assembled dimensions before you buy.
Getting Your Head Around Mattress, Frame, and Bedding Sizes
It’s a classic mistake. You’ve measured your space, bought a king bed, and then… it doesn't quite fit. That’s because the standard NZ king size dimensions of 168 x 203 cm refer only to the mattress. The bed frame you choose will always add extra centimetres to the total footprint.
This is a really important detail to get right, especially if you’re working with a smaller room. Forgetting to factor in the frame’s bulk can mean the difference between a cosy bedroom and one where you can’t open your wardrobe doors.
How Your Bed Frame Changes the Final Dimensions
Not all bed frames are created equal. A sleek, minimalist base will have a very different impact on your floor space compared to a grand, statement piece.
Here’s a rough guide to what you can expect:
- Platform Beds: These are often your most space-savvy option. Many are designed to be almost flush with the mattress, adding as little as 2–5 cm to the overall width and length.
- Frames with Headboards: A standard headboard will typically add about 5–10 cm to the bed’s total length.
- Sleigh Beds: These are the big ones. With their dramatic curved headboards and footboards, a sleigh bed can easily add 20 cm or more to the final length.
Pro Tip: Always look for the total assembled dimensions in the manufacturer's specs. Don't just rely on the mattress size it's designed for. This single step will save you a world of hassle and give you the true measurements for planning your room.
Choosing Bedding That Actually Fits
With the mattress and frame sorted, it's time for the final layer: the bedding. This is where a lot of people get tripped up. Your duvet, quilt, or flat sheet needs to be significantly larger than your mattress to give you that lovely drape over the sides and enough coverage to avoid a nightly tug-of-war.
For a standard NZ King mattress (168 cm wide), I always recommend a duvet that is at least 245 cm wide. This gives you a generous overhang of roughly 38 cm on each side, ensuring both of you stay comfortably tucked in all night.
Once you have your measurements locked in, finding the right bedding is the next logical step. You can even find options like King size fitted comforters designed specifically to match these dimensions perfectly.
What to Think About Before Buying a King Bed
So, you've got the king size bed dimensions in cm sorted out. That's a great start, but it's only half the story. Choosing to upgrade to a king is a big deal—it's an investment in your home and, more importantly, your sleep. It pays to think about the bigger picture before you hand over your credit card.
There are a few practical things that can really influence whether a king bed is the right fit for you in the long run. It's easy to get caught up in the excitement of a new purchase, but overlooking these details now can lead to surprise costs and moving-day nightmares later.
Before you make a final decision, it's always a good idea to check out a few different useful size guides to make sure you've covered all your bases. A little prep work now means you'll be happy with your choice for years to come.
It's More Than Just the Mattress Measurements
You might have measured your room and confirmed a king bed will technically fit, but have you thought about how it will feel in the space? A massive bed can completely dominate a smaller master bedroom, making it feel cramped and out of proportion, even if you have enough clearance to walk around it.
Think about what the future holds, too. Is your family expanding? A king bed is fantastic for weekend morning cuddles when the kids decide to pile in, making it a really practical option for young families.
Don't forget that a bigger bed comes with bigger ongoing expenses. King-sized sheets, duvets, and mattress protectors all cost more than their queen-sized equivalents. It's smart to factor this into your budget from the get-go to avoid any nasty surprises.
The Realities of Weight and Moving
One thing people almost always forget to consider is the sheer bulk and weight of a king bed. A king mattress and its base are seriously heavy and awkward, which can make them a real pain to move around.
Have a think about the logistics of moving it later on. If you're in an apartment with a narrow stairwell or you think you might move house in the next few years, the hassle of shifting a king bed is something you need to take seriously.
Here are a few final points to mull over:
- Delivery Day: Can the delivery truck get down your driveway? And more importantly, can the team get the bed through your front door and hallways? Double-check those access points.
- Putting it Together: Some of the more elaborate bed frames can be tricky to assemble and require a fair bit of space to do it.
- Linen Cupboard Check: King-sized bedding is bulky. Make sure you actually have enough room to store it all!
Thinking through these practical details ensures your new king bed is a source of comfort and joy, not a logistical headache.
Your King Bed Questions Answered
Choosing a new bed often brings up a few questions. It’s a big purchase, and getting the details right matters. Here are some clear, simple answers to the most common queries we hear about king bed dimensions.
What are the exact dimensions of a standard NZ King bed in cm?
A standard New Zealand King mattress measures 168 cm wide by 203 cm long. This is the go-to size across all major Kiwi brands and retailers, so it's the number you'll want to use when planning your bedroom layout or shopping for a new bed frame and linen. That extra width is precisely why so many people upgrade from a Queen.
Is a Super King bigger than a California King?
This one trips a lot of people up, and the answer is: it depends on what you mean by "bigger". One is wider, the other is longer.
- NZ Super King: At 183 cm wide x 203 cm long, this is the widest bed you can get. It’s perfect for couples who really value their personal space, or for family weekend morning cuddles.
- NZ California King: This one is 168 cm wide x 213 cm long. It keeps the same width as a standard King but adds a crucial 10 cm in length, which is a game-changer for anyone over six feet tall.
So, if "bigger" to you means more overall sleeping area, the Super King wins. But if it means more legroom to stop your feet from dangling off the end, the California King is the clear victor.
Will Australian King sheets fit my NZ King bed?
Unfortunately, no, they won't be a good fit. An Australian King mattress is 183 cm wide by 203 cm long, which is actually the same size as a New Zealand Super King.
If you try to put Aussie King fitted sheets on a standard NZ King mattress (168 cm wide), you’ll end up with baggy, loose fabric that bunches up and shifts around while you sleep. For that snug, hotel-quality feel, always make sure you're buying bedding specifically labelled for NZ King dimensions.
A quick tip: When buying bedding, especially if you're shopping online from an international store, always double-check the dimensions in centimetres on the packaging. It’s a simple step that can save you a lot of hassle.
How much space do I need to leave around a King bed?
To keep your bedroom feeling spacious and easy to move around in, a good rule of thumb is to leave at least 70 to 75 cm of clear space around the sides. You’ll want this on at least two sides of the bed—usually the sides you use to get in and out.
This gives you enough room to walk comfortably, make the bed without wrestling with the wall, and fully open the drawers of your bedside tables or any nearby dressers. A great trick is to use masking tape to mark out the bed's dimensions on the floor before you buy. It’s the best way to get a real-world feel for how much space you'll actually have.
