In New Zealand, a standard single mattress measures 91cm wide by 188cm long. It’s the go-to size for a child's first proper bed, a perfect fit for bunk beds, and a smart choice for making the most of a compact guest room.
Your Quick Guide to NZ Single Mattress Dimensions
Choosing the right mattress starts with the right measurements. The standard single is a Kiwi favourite for its space-saving design, but knowing the exact dimensions is crucial to ensure it fits your room and suits whoever will be sleeping on it.
This is especially true when comparing it to other popular sizes, like the slightly larger king single. A few centimetres might not sound like much, but it can be the difference between a comfortable night's sleep and a cramped one, or a room that feels spacious versus one that’s dominated by furniture.
NZ Single vs King Single Dimensions At a Glance
To make the choice crystal clear, here’s a straightforward comparison between the two most common smaller mattress sizes in New Zealand. This table really highlights the extra room you gain with a king single.
| Mattress Size | Dimensions (cm) | Dimensions (inches) |
|---|---|---|
| NZ Single | 91 x 188 cm | 35.8 x 74 in |
| NZ King Single | 107 x 203 cm | 42.1 x 79.9 in |
As you can see, jumping up to a King Single gets you an extra 16cm in width and 15cm in length. That's a significant upgrade, especially for a growing teenager or any adult who appreciates a bit more room to stretch out.
The Complete NZ Mattress Size Reference Guide
Getting your head around single mattress dimensions is a great start, but it’s only part of the story. New Zealand homes come in all shapes and sizes, and luckily, so do our mattresses. Once you look beyond the standard single, you'll find a whole range of options perfect for guest rooms, growing kids, couples, or anyone who just wants more room to sprawl.
Each size up offers more width or length, and those extra centimetres can make a huge difference to your sleep quality. A King Single, for instance, is a lifesaver for a lanky teenager, while a Queen is the starting point for most couples. Nailing these differences means you can pick a mattress that fits not just your room, but your lifestyle.
This chart gives you a quick visual comparison between a standard NZ Single and a King Single, highlighting the difference in size.
As you can see, the jump from a Single to a King Single provides a decent amount of extra width and, importantly, significantly more length. This makes it a much better long-term investment for anyone who's still growing.
Comparing All Standard NZ Mattress Sizes
To help you find that perfect fit, let's walk through the full lineup of standard mattress sizes you’ll find here in New Zealand. Every size is designed with a specific sleeper or room size in mind.
Here’s a practical rundown of all the standard options, from the compact Single right up to the massive Californian King:
- Single (91 x 188 cm): The classic choice for a child's first bed, bunk beds, and small spare rooms where every centimetre counts.
- King Single (107 x 203 cm): A fantastic option for growing teenagers, taller adults, or anyone sleeping solo who fancies more room to stretch out.
- Double (137 x 188 cm): A versatile size. It’s generous for one person and can work for a couple in a smaller main bedroom. If you're curious, you can find out more in our guide to the double bed size in NZ (cm).
- Queen (153 x 203 cm): New Zealand's most popular mattress size, and for good reason. It offers comfortable space for most couples and fits neatly into average-sized master bedrooms.
- King (167 x 203 cm): A great upgrade for couples who want more elbow room. You get extra width for more personal space without taking up any more length in the room.
- Super King (183 x 203 cm): The ultimate choice for couples who value their space or for families who enjoy a weekend morning cuddle with the kids.
- Californian King (203 x 203 cm): A perfectly square mattress that delivers maximum sleeping area for a truly luxurious, grand bedroom.
Making the right choice is a big deal, especially when you consider market trends. According to industry data, the New Zealand mattress market recently saw its value contract to $31 million, a decline of 16.2%. This highlights how economic pressures are affecting household spending, making it all the more important to invest your money wisely in a mattress that will serve you well for years to come.
Deciding Between a Single and King Single
Trying to choose between a standard single and a king single mattress is a classic dilemma for many Kiwi families. The measurements on paper might not look that different, but that small change can make a huge difference to comfort, sleep quality, and how long the bed will be useful. A standard single is a fantastic space-saver, making it the perfect fit for smaller kids' rooms, bunk beds, or that first 'big kid' bed.
The king single, however, offers a noticeable upgrade in both width and length. That extra room isn't just a luxury; it's a practical feature, especially for growing kids and teenagers. The added length means they won't suddenly outgrow it after a growth spurt, and the extra width gives restless sleepers more space to toss and turn without feeling boxed in.
Key Considerations for Your Decision
The main point of difference is the size. A king single gives you an extra 15cm in length and 16cm in width compared to a standard single. For taller kids or adults, this completely changes the sleeping experience – no more feet dangling off the end of the bed!
This added space also means the bed has a longer lifespan in your home. A single might be perfect for a five-year-old, but you could find yourself needing to upgrade it just a few years later. Starting with a king single can often be the more sensible financial choice, saving you from buying another bed down the line. To get into the nitty-gritty, check out our complete guide to king single dimensions on the blog.
When a Standard Single Is the Right Choice
Even with the benefits of a bigger bed, a standard single is still the best option in a few key situations. Its compact size is unbeatable when you need to make the most of the floor space in a small bedroom, leaving more room for a desk, toys, or just general play.
Here’s when a single mattress truly shines:
- Small Bedrooms: When every centimetre of floor space counts.
- Bunk Beds: These are almost always designed to fit standard single mattress dimensions.
- Young Children: It’s the perfect size for a toddler's first proper bed after graduating from a cot.
- Guest Rooms: Ideal for a spare room that's only used occasionally by a single guest.
In the end, it’s all about balancing your immediate needs with the future. Think carefully about who the bed is for, how much they might grow, and the size of the room to make the smartest choice for your home.
Planning Your Room Layout and Bed Placement
Knowing the exact dimensions of a single mattress is one thing, but making it work in your room is another challenge entirely. There's nothing worse than getting a new bed home only to find it turns your bedroom into an obstacle course. Taking a few minutes to measure and plan is key to making sure your bed is a relaxing centrepiece, not a bulky mistake.
This isn't just about floor space; it’s about how you live in the room. You need to think about everyday movements, like opening wardrobe doors, pulling out drawers, and simply walking around comfortably. A well-placed bed complements the room's layout instead of fighting against it.
The Golden Rule of Clearance Space
Here’s a tip straight from the interior design playbook: always aim for at least 60-70cm of clearance space around the main walking paths of the bed. This is the minimum space you need to move freely, make the bed without a struggle, and stop the room from feeling cramped and cluttered.
That buffer zone is what separates a room that feels thrown together from one that’s been thoughtfully designed. It's the difference between shuffling sideways to get to your wardrobe and moving with ease.
When you're figuring out where the bed will go, keep these common room features in mind:
- Door Swings: Make sure your bedroom door can open fully without hitting the bed frame.
- Wardrobe and Drawer Access: Can you open your closet doors and pull out drawers all the way? Don't forget to check.
- Radiators and Vents: Blocking a radiator isn't just inefficient; it can be a safety hazard. Keep the bed clear.
- Windows: Placing a bed under a window can be lovely, but consider potential draughts and whether you can still open and clean the window easily.
Mapping Out Your Bedroom
The best way to be certain is to get physical. Grab a tape measure and map out the single mattress dimensions (91cm x 188cm) on the floor with some painter's tape. This simple trick gives you a perfect visual of how much real estate the bed will actually occupy. For a deeper dive into arranging your space for the best flow, check out these essential furniture arrangement tips.
Once the bed's footprint is marked out, you can see how everything else fits around it. After all, a bed is just one piece of the puzzle. If you need inspiration for matching nightstands, dressers, or other items, have a look at our guide on choosing the right bedroom furniture in NZ. A little planning goes a long way in creating a room that feels both balanced and genuinely relaxing.
Matching Your Mattress to the Right Bed Frame
You've picked out the perfect single mattress, which is fantastic—but that's only half the job. Your bed frame is much more than just a platform; it's a key piece of furniture that anchors your room's style and takes up significant floor space. Getting the dimensions wrong can lead to a range of issues, from poor mattress support to a room that looks and feels unbalanced.
A common mistake is focusing only on the mattress size. A chunky sleigh bed or a frame with an oversized headboard can easily add an extra 10-20cm to the total length and width. Before you commit, always measure the external dimensions of the frame itself to ensure it will fit, leaving you enough room to walk around comfortably.
Understanding Different Base Types
The type of base you pair with your mattress has a huge impact on support, airflow, and how long your mattress lasts. It's a crucial decision because using an incompatible base can sometimes even void your mattress warranty.
Here’s a quick rundown of the most common options you’ll find in New Zealand:
- Slatted Bases: These frames use wooden or metal slats to support the mattress. They’re great for ventilation, helping to keep your mattress fresh and dry. Just make sure the gaps between the slats are no wider than 7cm, otherwise you risk the mattress sagging and losing support.
- Ensemble Bases (Foundations): Think of an ensemble as a sturdy, fabric-covered box. It provides a solid, flat surface for your mattress, offering firm, consistent support right to the edges. This is often the best choice for memory foam or hybrid mattresses.
It’s also interesting to see how our market compares to others. While New Zealand's mattress market is healthy, Australia's is projected to hit USD 738.91 million—nearly nine times larger. This difference in scale can affect the range and availability of certain specialty bed frames. You can learn more about the New Zealand mattress market on Statista.com.
A supportive base is non-negotiable. It protects your investment by preventing premature sagging and ensures you get the comfort and support you paid for, night after night.
If you’re trying to make the most of a smaller room, some frames come with clever built-in solutions. Have a look at our guide on bed frames with storage to see how you can boost functionality without giving up on style.
Choosing the Right Bedding and Sheets
You’ve found the perfect mattress, but the job isn't quite done. Now comes the final, crucial step: finding bedding that fits properly. It’s a common mistake—grabbing any single-size sheet set off the shelf, only to get home and discover it’s a constant battle to keep it on the bed. This is especially true now, as modern mattresses are often much deeper than older ones, thanks to plush pillow tops and extra comfort layers.
The secret to a perfect fit? It all comes down to pocket depth. This is the measurement of the corner seam on a fitted sheet, and it’s arguably the most important number to check. Your fitted sheet's pocket needs to be deeper than your mattress is thick; otherwise, those corners will pop off the second you roll over.
Getting the Perfect Fit and Feel
Before you go shopping, grab a measuring tape and check the exact height of your mattress. A little prep work here saves a lot of frustration later. For instance, if you have a 30cm thick mattress, you’ll need a fitted sheet with a pocket depth of at least 35cm. That extra length gives you enough fabric to tuck securely underneath, holding it firmly in place.
Here are a couple of practical tips that can make a huge difference to how your single bed looks and feels:
- Upsize Your Duvet: A double-size duvet on a single bed is a game-changer. The generous overhang gives it a more luxurious, hotel-style look and completely eliminates any chilly drafts if you tend to move around in your sleep.
- Layer for Style: Don't just stop at the essentials. Adding layers like throws or accent cushions can really elevate the look of your bed. For some great ideas, check out this guide on What Is a Throw Blanket Used For and How to Style One.
A well-fitting fitted sheet is the foundation of a comfortable bed. It should be taut and smooth, without frustrating wrinkles or corners that refuse to stay put, ensuring an uninterrupted night's sleep.
By paying attention to these simple details, you can ensure your bed is not just a comfortable place to sleep, but also a beautifully styled centrepiece of your room.

Your Top Mattress Questions Answered
Choosing the right mattress size can feel overwhelming, and it's easy to get lost in the details. To make sure you get it right, we've put together straightforward answers to the questions we hear most often from our customers here in New Zealand.
Getting the little things right – like how our sizes compare to those overseas or why mattress thickness is so important – is key to buying a bed you'll be happy with for years to come.
Key Mattress Dimension Questions
What Are the Exact Single Bed Dimensions in NZ?
In New Zealand, a standard single mattress measures 91cm wide by 188cm long (91 x 188 cm). Its compact footprint makes it a fantastic choice for a child's first bed, bunk beds, or for fitting into a smaller guest room or sleepout where every centimetre counts.
Is a NZ Single the Same as a UK Single or US Twin?
Not quite, and this is where it pays to buy local. While they sound similar, there are small but important differences. A NZ single (91 x 188 cm) is a fraction wider and shorter than a US Twin (96.5 x 190.5 cm). It’s very close to a UK single (90 x 190 cm), but even that tiny difference can mean your fitted sheets are either too loose or a real struggle to get on. For a snug, perfect fit every time, stick with bedding made specifically for NZ sizes.
Understanding Mattress Compatibility
What Is Mattress Depth and Why Does It Matter?
Mattress depth, or thickness, can vary significantly, from a slim 15cm profile right up to a luxurious 35cm or more. This measurement is crucial for two reasons: your comfort and whether your sheets will fit. Thicker mattresses often have more layers for cushioning and support, while thinner, lower-profile models are a must-have for bunk beds to keep the safety rails effective.
It's so important to match your fitted sheet's 'pocket depth' to your mattress thickness. If the sheet pocket is too shallow, you'll be fighting with the corners popping off all night, which is incredibly frustrating.
Can I Put a King Single Mattress on a Single Base?
We strongly advise against this. A king single mattress is both wider and longer than a single base, so the edges of the mattress would overhang the sides. This overhang means the mattress isn't properly supported, which can cause it to sag and wear out much faster. On top of that, it will almost certainly void your warranty. Always make sure your mattress and base are the same size for optimal support and longevity.
