What Size Mattress Do I Need? A Kiwi's Guide to Choosing the Perfect Fit
Choosing the right mattress size is one of the most important decisions when furnishing your bedroom. Too small and you'll struggle to get comfortable; too large and you might overwhelm your space. With so many options available to New Zealand shoppers, from Single to Super King, finding the perfect fit for your needs can feel overwhelming.
This straightforward guide will help you understand the standard mattress sizes available in New Zealand, their dimensions, and how to choose the right one for your specific situation.
Standard Mattress Sizes in New Zealand
Unlike some countries, New Zealand follows a relatively straightforward mattress sizing system. Here are the standard dimensions you'll encounter:
Single
Dimensions: 92cm × 188cm
Perfect for:
- Children and teenagers
- Guest rooms with limited space
- Smaller adults in compact bedrooms
A Single mattress provides enough space for one person to sleep comfortably while taking up minimal floor space. It's an economical choice for kids' rooms and smaller guest spaces.
King Single
Dimensions: 107cm × 203cm
Perfect for:
- Taller teenagers
- Adults in space-constrained rooms
- Guest rooms offering more comfort than a standard Single
The King Single offers extra length and width compared to a standard Single, making it ideal for taller individuals who don't have room for a larger bed.
Double
Dimensions: 138cm × 188cm
Perfect for:
- Single adults who prefer more sleeping space
- Couples in very small bedrooms
- Guest rooms accommodating two people occasionally
While a Double can accommodate two adults, it provides each person less width than they would have in a Single bed, so it's best for occasional sharing or those who don't mind close proximity.
Queen
Dimensions: 153cm × 203cm
Perfect for:
- Couples who prefer more personal space
- Single sleepers who enjoy sprawling out
- Master bedrooms in average NZ homes
The Queen size is the most popular choice for couples in New Zealand, offering a good balance between spaciousness and room fit.
King
Dimensions: 168cm × 203cm
Perfect for:
- Couples who value personal sleeping space
- Families with young children who occasionally co-sleep
- Larger master bedrooms
A King mattress gives couples significantly more room than a Queen, with each person enjoying about 84cm of personal space—similar to a Single bed.
Super King
Dimensions: 183cm × 203cm
Perfect for:
- Those who prioritize maximum sleeping space
- Families where children or pets frequently co-sleep
- Spacious master bedrooms
The Super King is the ultimate luxury option, offering expansive sleeping space for couples who want plenty of room to spread out.

How to Choose the Right Mattress Size
Consider Your Room Dimensions
Before choosing a mattress, measure your bedroom carefully:
- Allow for walkways – Keep at least 70-80cm of clear space around the sides of the bed for easy movement
- Consider furniture placement – Ensure doors, wardrobes, and drawers can fully open
- Account for bedside tables – These typically need 40-50cm on each side
- Check delivery access – Ensure larger mattresses can navigate through doorways and hallways
For reference, here are typical minimum room sizes for different mattress dimensions:
- Single: 2.5m × 3m room
- King Single: 2.5m × 3.2m room
- Double: 3m × 3m room
- Queen: 3.2m × 3.2m room
- King: 3.5m × 3.2m room
- Super King: 4m × 3.2m room
Think About Who's Sleeping
Different sleeping arrangements call for different mattress sizes:
For Individuals
- Consider your height, build, and sleeping style
- If you're over 183cm tall, choose a King Single, Queen, or larger for adequate length
- If you move frequently during sleep or like to spread out, go up a size from what you might minimally need
For Couples
- Two adults sharing a Double bed get less personal space than a child in a Single
- Queen is generally the minimum comfortable size for two adults
- Consider how likely you are to have children or pets joining you occasionally
For Kids
- Single beds are appropriate for most children
- Consider a King Single for rapidly growing teenagers
- Bunk beds often use Single mattresses, but check the specific requirements of your bunk bed frame
Factor in Your Future
A quality mattress should last 7-10 years, so think ahead:
- Will your living situation change?
- Are you planning to move house?
- Might your relationship status change?
- Do you anticipate children joining your family?
Investing in a slightly larger mattress now might save you from needing to upgrade sooner than expected.
Beyond Size: Other Mattress Considerations
While this guide focuses on dimension, remember that the perfect mattress also depends on:
Mattress Type
Different construction styles offer varying benefits:
- Innerspring provides traditional bounce and support
- Memory foam contours to your body for pressure relief
- Latex offers natural resilience and durability
- Hybrid combines the benefits of multiple materials
Firmness Level
The right firmness depends on your sleeping position and preferences:
- Side sleepers typically need softer mattresses
- Back and stomach sleepers often prefer firmer support
- Heavier individuals generally need firmer mattresses for adequate support
Temperature Regulation
New Zealand's varied climate means you should consider how your mattress handles temperature:
- Gel-infused foams and breathable covers help with cooling
- Traditional memory foam can retain heat
- Spring mattresses typically offer better airflow
Mattress Size FAQs
Can I use my overseas mattress dimensions in New Zealand?
New Zealand generally follows standard measurements that are similar to Australian sizes, but they may differ from European, UK, or American dimensions. Always check specific measurements rather than just the size name.
Should I choose the same size as my current mattress?
Not necessarily. Consider if your current size truly meets your needs or if you've been compromising on comfort due to space or budget constraints.
Will a larger mattress automatically be more comfortable?
While more space can improve sleep quality for many people, comfort also depends on the mattress type, materials, and support. The right Single mattress could be more comfortable than a poorly made Queen.
Do I need to buy new bedding if I change mattress size?
Yes, sheets, mattress protectors, and often duvets are sized specifically to fit different mattress dimensions. Factor this into your budget when upgrading.
