Ever tossed and turned at night or woke up with a headache, even more tired than before you went to bed? If that’s the case, your bed may not be the right size for you. Uncomfortable sleep triggers headaches, random body pains, and even the feeling that you just need to get through the day until you get to bed again. For that reason, you need a quality mattress in the right size.
Australian Bed Sizes vs International Bed Sizes
Before you start a hunt for a new mattress, you should know that different countries use different standards, so what’s called a “Queen” or “King” overseas may not exactly match the dimensions you’ll find in Australia. To help your search, here’s a quick guide to size comparisons and the main mattress types available here.
Size Comparison: Australia vs Overseas
There’s no single global standard for bed sizes, which means names and sizes don’t always line up. For example, a US Queen bed is close to an Australian Queen, but US Kings and California Kings differ in width and length.
And, if you’re shopping based on UK sizes, singles and kings are typically smaller than their Australian counterparts, so bedding or frames you buy from overseas may not fit perfectly here.
Single Mattress
If you’re a parent, single bed mattress sizes measure 92 × 188 cm and are best suited for children. They are also the go‑to size for bunk beds and trundles, making it practical for compact rooms.
Singles work as well for smaller adults who are solo sleepers. Sheet sets and bedding are widely available and usually the most affordable option.
King Single Mattress
At 107 × 204 cm, the king single mattress size offers some additional length and width compared to a standard single. This makes it perfect for teenagers or taller individuals who need more space but don’t necessarily want to switch to a double, whether it’s due to budget constraints or limited room space.
You may also find it under the name “long single,” as some brands would like to call it, so keep that in mind when shopping for sheets.
Double Mattress
A standard double measures 138 × 188 cm, but honestly, it is often considered snug for two people. It works best for solo sleepers who want a bit more room, and also adds a polished look to guest bedrooms. Today, a double mattress is way less common, but it still remains a favoured option for smaller spaces where a queen mattress takes up too much space.
Queen Mattress
The most popular mattress size Australia-wide, the queen bed measures 153 × 203 cm. These dimensions offer quality sleep and comfort for couples and practicality for most bedrooms. Queen sheets are the easiest to find, and as this mattress is the most popular one, there are plenty of styles at different price points.
King Mattress
Compared to queen mattress sizes, king beds offer 30 cm more width for extra comfort. They measure at 183 × 203 cm, so couples enjoy almost the same space as if they both had a single bed each. This is a luxurious upgrade, and your bedroom needs to be large enough to accommodate the extra size without feeling cluttered.
Super King Mattress
The super king is Australia’s largest standard size at 204 × 204 cm. Although it’s not nearly as popular as the other bed mattress sizes, there are plenty of couples that wouldn’t change it for a thing.
Its square shape provides maximum sleeping space, ideal for families with small children who co-sleep, couples with pets, or anyone who appreciates extra room to stretch. Sheets can be harder to find and typically cost more, but the comfort is unmatched.
Mattress sizes vary around the world, so knowing Australia’s standards helps avoid confusion. From singles to super kings, all mattress sizes serve different lifestyles and space requirements.
Mattress Size Considerations
Shopping for a mattress is a decision that will affect your life for a decade, so naturally, it can feel a little overwhelming. Choosing the type and the right size depends on how you sleep, the space you work with, and what you’re willing to spend. Here are some important things to keep in mind.
Do You Share a Bed?
For solo sleepers, a single or king single is usually plenty of space. If you’re sharing your bed with a partner, a queen or double mattress will feel much more comfortable. And for families with kids or pets who often climb into bed, a king or super king gives everyone the room to recharge their batteries with quality sleep.
What Fits Your Bedroom Best?
Your room size is not something to overlook when shopping for a bed mattress. Smaller rooms look neat and spacious with singles, doubles, or queens, while larger master bedrooms can fit a king or super king without looking too busy. Aim for at least 60 cm of free space around your bed so the room feels comfortable, not cramped.
How Tall Are You?
No one likes losing quality sleep due to their feet dangling off the edge. If you’re taller, you should look at king singles, queens, or kings, all of which measure 203 cm in length. If you’re 190cm, these sizes will give you the stretch room you need.
What’s Your Budget?
Bigger beds, naturally, cost more and not just for the mattress, but also for frames and bedding. Although beds aren’t something you really want to cut corners on, if you’re working with a tighter budget, it makes sense to stick with smaller sizes or check out affordable foam and hybrid options.
Other Things to Keep in Mind
Measure your bed frame to be sure your mattress fits it perfectly. Think ahead about how your lifestyle might change, and factor in future needs like moving homes or sharing with a partner or pet. A mattress is a long‑term investment, so future‑proofing your choice is always a smart move.
Finding the right bed mattress sizes is a choice that depends on how you live, who you share your bed with, and the space you work with. When you weigh up these factors, the choice becomes much clearer. Pick the size that fits your lifestyle best, and you’ll be setting yourself up for years of restful, cosy sleep.
