Getting enough sleep can help us lead our best lives but the million-dollar question is how do you determine if your mattress is the right size for you? Whether you’re shopping around for yourself, a family member or to fill a spare bedroom in preparation for those unexpected guests, Snooze offers an extensive range of beds and mattresses to help you achieve a better night sleep. It’s time to stop dreaming about a mattress which is a little longer, wider or bigger and explore the different bed dimensions available to you. Read on for the factors you should consider when determining the size of your next mattress.

1. Find your size


Mattress sizes are determined by length and width, from single mattresses for growing kids to super king ensembles, preferred by space-lovers with large rooms. Before you start making the important decision about which size to buy, ensure you measure your room and compare its layout with the listed dimensions in the bed size chart below.

2. How to choose a mattress


On the other hand, If space isn’t a problem and the decision is based on wants alone, consider if the mattress will fit, who will be sleeping on it and how often it will be used when exploring each benefit and potential drawback. Remember if you have questions, our Snooze team can help you take the guesswork out of buying your next mattress in-store.

The single bed size isn’t only for kids, it suits all ages. Single mattresses help space-starved adults make the most out of small studio apartments and share house bedrooms, ensuring they have somewhere comfortable to sleep after a long, tiring day. The downside? They’re not made to be divided between adults or their demanding furry friends - if you’re planning on sharing the mattress or for the mattress to be shared by others, we would always suggest bigger is better.

The humble double still has a lot to give. It can be perfect for guest rooms, teen upgrades and those who sleep alone but need spare inches to toss or turn, double mattresses have some of the space-saving abilities of singles without sending one half of visiting couples to the couch. On the other hand, if you're investing in a couples bed for yourself and your partner, a double may not deliver the sleep experience you desire night after night. It really depends on how cosy you want to be!

Queen mattresses are the new normal when it comes to choosing mattresses for master bedrooms. Widely regarded as the shared bed of choice, 152.5cm gives each sleeper 76.25cm of legroom throughout the night - which equates to seven whole centimetres more than a double! A little space can go a long way in ensuring everybody gets enough sleep, although some doorways do struggle with larger mattresses - particularly those in older houses. Plan how you'll get your queen size through the door before you purchase to prevent having to downsize.

king size mattress can equal an undisturbed night of deep sleep, delivering the kind of experience you'd expect from snoozing solo in a single bed while sharing with your nearest and dearest. With so much space, it's difficult to imagine a king size having many drawbacks, but there are two - a large mattress can be heavy and difficult to move, plus those with a taller build may still struggle with their feet hanging over the end.

Have small children invaded your bedroom space? Then a super king mattress could be for you. Delivering relief to overwhelmed parents and a whole lot of luxury to those who don't have kids sneaking in for a cheeky snuggle, this mattress is gaining popularity as master bedrooms become sleep sanctuaries. While the positives far outweigh the challenges, keep in mind your mattress needs to last the distance - will you always have enough room for a super king? Or do you see yourself moving house in a few years?
