Choosing the correct mattress size is not just a practical decision—it’s one that directly impacts your quality of life. In New Zealand, we follow specific mattress size standards that cater to a wide range of needs, from growing kids to couples looking for luxurious sleeping space. Let’s break down these sizes and, frankly, let’s be honest about who they’re actually good for. Spoiler: some sizes just aren’t worth the compromise.
Here's the size table with dimensions converted to centimeters (mm):
| Mattress Size | Dimensions (mm) |
|---|---|
| Single Mattress | 915mm x 1900mm |
| King Single Mattress | 1055mm x 2030mm |
| Double Mattress | 1385mm x 1900mm |
| Queen Mattress | 1525mm x 2030mm |
| King Mattress | 1685mm x 2030mm |
| Super King Mattress | 1835mm x 2030mm |
| California King Mattress | 2030mm x 2030mm |
Single Mattress
Dimensions: 915mm x 1900mm
The Single mattress is the smallest size available in New Zealand’s standard lineup. At 915mm wide and 1900mm long, it’s fine for young children or as a backup in a guest room. But for adults? Unless you’re extremely petite or you never toss and turn, a single is likely going to feel restrictive. Sure, it saves space, but at what cost? Sleep is too important to sacrifice for the sake of squeezing into a smaller room.
King Single Mattress
Dimensions: 1055mm x 2030mm
The King Single is where things get interesting. At 1055mm wide and 2030mm long, it’s the sweet spot for older kids, teenagers, or single adults who want something more comfortable without taking up the space of a double bed. It’s still compact enough to fit into most bedrooms, making it a versatile option for apartments or guest rooms. For many, this size hits the perfect balance between practicality and comfort—especially for single sleepers who are done with feeling boxed in.
Double Mattress
Dimensions: 1385mm x 1900mm
Here’s where I start getting opinionated: the Double mattress is overrated. At 1385mm wide and 1900mm long, it’s a noticeable step up in width from a King Single, which can feel luxurious if you’re sleeping alone. But for couples? Let’s not kid ourselves—this size is barely wide enough to give two people adequate space. If you share your bed regularly, skip the Double and go straight for a Queen. That said, the Double still has its place, particularly in smaller rooms or as a guest bed.
Queen Mattress
Dimensions: 1525mm x 2030mm
The Queen mattress is the undisputed champion of New Zealand bedrooms. At 1525mm wide and 2030mm long, it offers enough space for most couples while still fitting comfortably into medium-sized bedrooms. It’s the perfect compromise between space efficiency and sleeping comfort, and for many, it’s all they’ll ever need. Unless you’re dealing with particularly tall partners or love sprawling like a starfish, the Queen gets the job done beautifully.
King Mattress
Dimensions: 1685mm x 2030mm
Now we’re stepping into luxury territory. At 1685mm wide and 2030mm long, the King mattress is for couples who value their personal space. If you or your partner are blanket hogs or restless sleepers, this size is a lifesaver. It’s the same length as a Queen but offers a wider surface to stretch out. But let’s be real—this size demands a larger bedroom. Don’t cram a King mattress into a space that barely fits it; the room needs to breathe just as much as you do.
Super King Mattress
Dimensions: 1835mm x 2030mm
The Super King mattress, measuring a whopping 1835mm wide and 2030mm long, is the pinnacle of spacious comfort. It’s ideal for couples who want plenty of room to stretch or for those who share their bed with kids or pets (yes, we see you co-sleepers out there). Because it’s often paired with split bases, it also minimizes partner disturbance, making it a practical choice for couples with different sleep patterns. But let me stress this: don’t even think about this size unless your bedroom can handle it. A cramped room will make even the most luxurious bed feel suffocating.
California King Mattress
Dimensions: 2030mm x 2030mm
This is it—the granddaddy of all mattress sizes in New Zealand. At 2030mm wide and 2030mm long, the California King is a literal square of sleeping luxury. If you’ve got the space and the budget, this is the ultimate indulgence. It’s perfect for couples who want unmatched space or for anyone who just loves the idea of a bed that feels like it belongs in a five-star resort. But be warned: finding bedding for this size can be a headache, and moving it into your home might require an engineering degree. If that doesn’t bother you, go for it. You’ll never regret having too much space.
Why New Zealand Mattress Standards Matter
These dimensions are specific to New Zealand, so don’t assume that international sizes will match up. If you’re shopping online or importing a bed frame, double-check compatibility with these local standards. Trust me, there’s nothing worse than realizing your new mattress doesn’t fit your frame—or worse, your room—after you’ve lugged it inside.
Final Verdict: Be Bold, Choose Wisely
Let me say this loud and clear: your mattress size is not something to compromise on. If you’re trying to save space or money by going smaller than you need, you’re only shortchanging yourself in the long run. Sleep is one of the most critical aspects of your health and well-being. Prioritize it. Get the size that truly fits your needs, your body, and your lifestyle. And if that means rearranging your room or spending a little extra? So be it. You’re worth it.
