What is the Biggest Bed Size? FAQs About the Best Mattress Size

Size does matter. One of the most critical decisions you can make is selecting the right size mattress for yourself, your child or you and your partner. Mattress size plays a key role in getting a good night’s sleep. No arms being smacked into a face, no feet hanging off the edge of the bed. Having the right mattress size is not just about individual comfort but also ensuring a blissful partnership and sleep with your loved one.

From single mattresses to California king mattresses, we’ll go over all the main bed sizes in New Zealand and how to pick the right one for you.


Standard mattress sizes in NZ, from smallest to largest

Single mattress

91W x 188L. A single mattress is the perfect mattress size for a kid’s first bed. It’s suitable for growing children with smaller bedrooms.

King single mattress

107W x 203L. A king single mattress works well for tall teenagers, providing extra length while not taking up too much space width-wise. The extra legroom also makes it suitable for an adult staying in a guest room.

Double mattress

137W x 188L. A double bed is a generous size for a single adult or teenager. It provides extra space for single sleepers while still fitting in most bedrooms and guest rooms.

Queen mattress

153W x 203L. A queen mattress is the minimum mattress size for couples. It has enough space to accommodate couples and fits easily in most rooms.

King mattress

167W x 203L. A standard king bed has enough room and length for an average-sized couple. The extra room is fantastic if you want a bigger bed with more space to move around.

Super king mattress

183W x 203L. A super king is perfect if you have a large bedroom. The mattress dimensions provide less partner disturbance, which is great for those who prefer not to feel their partner moving about as they sleep.

California king mattress

203W x 203L. And finally, the MacDaddy, a California king mattress. With all that extra room, you’d need a passport to get anywhere near your partner and/or have all the kids and the family dog in the bed with you.

How do I choose the right bed size for me?

There are three primary considerations when thinking about your mattress size:

  • How many people will be sleeping with you?
  • What is the size of the person sharing the mattress with you?
  • Do you co-share with your children and/or pets too?

Based on these considerations, you can compare the dimensions of different mattresses to find a suitable option with enough room (bearing in mind that kids may need extra width or length as they grow). You also need to make sure your mattress can fit your space!


What is the best bed size for couples?

As a rule, you need at least a queen-size mattress when sharing your bed with another person. Having more space ensures you aren’t disturbed by your partner’s movements during the night unless they sleep like a starfish or go around and around like a dog, finding its comfortable spot.

Another thing to consider is if one of you is particularly tall or broad. A queen bed might feel cramped – a bit too close for comfort. If you need more room, opt for a bigger mattress like a Cali king, super king, or king-sized mattress.

But here’s something you may never have considered. A super king bed is the size of two single mattresses together. So, if two people share a king-size bed, you’re each sleeping in a space smaller than a child's in a single bed.

So, no matter who you choose to sleep with, investing in the right size mattress is actually quite important. Don’t rush into picking a certain size mattress because that’s what you have always had. This is an 8-10 year investment.
