Choosing the right bed size can make a big difference to how comfortable your bedroom feels and how well you sleep. Whether you’re furnishing your child’s room, upgrading your own mattress, or choosing a new bed for your guest room, it helps to know and compare mattress dimensions before buying.

At Bevmarks, we know that the right bed doesn’t just depend on the size. It should suit your room’s layout, sleeping preferences, and future needs. In this guide, we’ll break down the most common mattress sizes and help you choose the best fit for your home.

Comparing Mattress Dimensions

Mattress sizes are generally standard across Australia. Here are the size dimensions to consider when comparing beds:

Mattress Size	Mattress Dimensions (cm)	Best Suited For
Single Mattress	92 cm x 188 cm	Children, bunk beds, and small rooms
King Single Mattress	107 cm x 203 cm	Teenagers, taller childre and solo sleepers
Double Mattress	138 cm x 188 cm	Solo sleepers, guest rooms and compact bedrooms
King Mattress	183 cm x 203 cm	Couples wanting more space
Super King Mattress	203 cm x 203 cm	Large bedrooms and maximum comfort

 

Tips For Choosing The Right Bed Size

When comparing various bed sizes, keep these points in mind:

• Who will use it: A single mattress might suit a child, while a queen mattress is ideal for couples
• Your sleeping preferences: If you stretch out or move a lot in your sleep, a larger bed like the double mattress would be more comfortable 
• Room size: Make sure there’s enough space to put other bedroom furniture and room to move around your bed
• Future needs: For long-term use, it’s best to choose the largest mattress size your room can comfortably accommodate.

It is also worth thinking about future needs. If you are upgrading your main bedroom, choosing the largest size your room can comfortably fit may be worthwhile. If you are furnishing a rental or apartment, a more compact size may be easier to move and style.

Single Mattress Size 

A single mattress size is a practical choice for children’s bedrooms, bunk beds or smaller guest rooms. Measuring at 92 cm x 188 cm, it provides enough room for young children and leaves plenty of space for toys, desks, and other bedroom furniture. 

Explore our range of single mattresses to find a practical and comfortable option for kids’ rooms and compact bedrooms.

King Single Mattress Size 

A king single mattress measures 107 cm x 203 cm, making it slightly wider and longer than a single mattress. This makes it a popular option for taller sleepers who want extra room without having to move up to a double bed.

King single mattresses are also a smart choice for smaller rooms, especially in narrow rooms. It is just slightly wider than a single mattress, but provides extra length for sleepers who need the space.

If you need more room without taking up too much space, explore our collection of king single mattresses.

Double Mattress Size

A double mattress is a great option for solo sleepers who would appreciate more space compared to a king single bed. It can also work well for couples who don’t mind sharing the smaller space.

Measuring at 138 cm x 188 cm, it is slightly wider and shorter than a king single mattress, making it a reasonable choice for compact bedrooms and guest rooms.

Find a double mattress that balances comfort, space, and practicality for better sleep.

Queen Mattress Size

A queen mattress is one of the most popular bed sizes in Australia. With dimensions of 153 cm x 203 cm, it offers the perfect balance of sleeping comfort and bed space.

For most couples, a queen bed is the best all-around option. It gives both sleepers more room than a double bed, while still fitting comfortably in most primary bedrooms. It’s also a great choice for solo sleepers who appreciate the extra space.

If you’re browsing through different options made for two people to sleep on, a queen bed is the safest option to start with.

King Mattress Size

A king mattress is one of the best options for larger primary bedrooms, where the bed can sit comfortably without making the room feel crowded. It measures 183 cm x 203 cm, offering an extra 30 cm of width compared to a queen bed.

Before choosing a king mattress, measure your room carefully to make sure there is still enough space for bedside tables, drawers, and for you to move through the room easily.

If you’re looking for a mattress that offers generous space and a more luxurious sleeping experience, then a king mattress might be the perfect choice for you.

Super King Mattress Size

A super king mattress is the largest standard mattress size that you can get in Australia. Measuring 203 cm x 203 cm, it is best suited to large primary bedrooms and couples who are looking for the highest quality and comfort you can get from a mattress.

The super king mattress is ideal for anyone with large bedrooms and looking for the best sleeping comfort at home.

Mattress Size & Bed Frame Size

When measuring your room, it’s important to note that mattress dimensions and bed frame dimensions aren’t always the same.

A bed frame will typically be wider or longer, especially if it includes a bedhead, footboard, or storage drawers. For example, a queen mattress measures 153 cm x 203 cm, but a queen bed frame can measure 166 cm x 221 cm, taking up more space.

If you are looking for a mattress to put into a compact room, consider a slimline base to avoid taking up too much space. If you can afford the extra room, you may prefer a luxurious bed frame or a bed base with built-in storage. 

Why It's Important To Choose The Right Bed Size 

Choosing the right bed size helps create a bedroom that feels comfortable, practical and easy to use every day. A bed that’s too small can leave you feeling restless or feel like you’re in a tight space, while one that’s too large can make the room feel crowded and difficult to move around in.

The right size should give you enough space to sleep comfortably, suit your body and sleeping habits, and still leave room for other furniture. For couples, choosing the right size can also reduce any sleep disturbances or discomfort.

Taking the time to compare your options means you’re likely to choose a bed that works for your current lifestyle and into the future.
