What Mattress Size Is Right for Your Bedroom?

Choosing the right mattress size is about more than selecting the largest bed that fits inside the room. You also need enough space to walk comfortably, open doors and drawers, position bedside tables and access both sides of the bed.

Before ordering, measure your bedroom carefully and check both the mattress dimensions and the complete external dimensions of your chosen bed frame.

Common Australian Mattress Sizes

The following measurements are commonly used as general Australian mattress size guides. Small variations can occur between manufacturers, so always check the individual product specifications before purchasing.

• Single: approximately 92cm × 188cm
• Long Single: approximately 92cm × 203cm
• King Single: approximately 107cm × 203cm
• Double: approximately 138cm × 188cm
• Queen: approximately 153cm × 203cm
• King: approximately 183cm × 203cm

Single Mattress

A Single mattress is a practical choice for children, teenagers, guest rooms and compact bedrooms. It leaves more floor space for desks, storage or play areas.

Because a standard Single is shorter than a King Single, taller teenagers and adults may prefer the additional length of a Long Single or King Single.

Long Single Mattress

A Long Single usually provides the width of a standard Single with the length of a Queen or King mattress.

It may suit taller solo sleepers, adjustable bed bases, narrow guest rooms or situations where two Long Single mattresses are placed side by side.

King Single Mattress

A King Single provides more width and length than a standard Single, making it a popular option for teenagers, adults sleeping alone and long-term guest rooms.

It requires more bedroom space than a Single, but remains significantly narrower than a Double.

Double Mattress

A Double mattress can provide a comfortable amount of room for one person and may accommodate two people where bedroom space is limited.

However, it provides considerably less personal space per person than a Queen or King. Couples should consider whether the reduced width will be comfortable for regular long-term use.

Queen Mattress

Queen is one of the most popular mattress sizes for Australian couples. It provides more width and length than a Double without requiring as much room as a King.

A Queen mattress often suits main bedrooms, larger guest rooms and couples who want a practical balance between sleeping space and room layout.

King Mattress

A King mattress offers generous width for couples and may suit sleepers who change position frequently or share the bed with children or pets.

It requires a larger bedroom, wider access paths and a suitable bed frame. Customers should also consider whether the mattress can fit through hallways, staircases, doorways and lifts.

Measure the Bed Frame, Not Only the Mattress

An upholstered or timber bed frame is usually larger than the mattress. A Queen mattress may measure approximately 153cm wide, but the complete bed frame may be 160cm, 170cm or wider.

Tall or winged headboards can also increase the overall width and height. Always use the assembled frame dimensions when planning the bedroom layout.

Allow Space Around the Bed

Where possible, leave enough room to walk beside the bed and access bedside tables, wardrobes and drawers.

Consider the following:

• Can bedroom and wardrobe doors open fully?
• Can drawers be opened without hitting the bed?
• Is there comfortable access to both sides?
• Will bedside tables fit beside the frame?
• Is there enough space at the end of the bed?
• Can the mattress and frame packages enter the property?

Choosing a Size for Couples

Couples should consider how much personal sleeping space they prefer, whether either person moves frequently and how the bed will fit within the room.

A Queen is a practical choice for many couples. A King offers additional space but may make a medium-sized bedroom feel crowded.

Choosing a Size for Children and Teenagers

A Single can be suitable for younger children, while a King Single offers additional room for growth. A Double may be considered when the bedroom is large enough and the bed is expected to remain in use for many years.

Choosing a Size for a Guest Room

For a compact guest room, a Single or King Single maintains more usable floor space. A Double can accommodate occasional couples, while a Queen creates a more generous guest-room experience where space allows.

Final Measuring Tips

• Measure the room more than once
• Mark the bed dimensions on the floor with removable tape
• Include the complete external bed-frame dimensions
• Check hallways, doorways, stairs and lifts
• Confirm the mattress size before ordering bedding
