What Are the Dimensions of Queen Size Mattress?

The standard dimensions of queen size mattress in Australia are approximately 153 cm wide × 203 cm long. In millimetres, this is 1,530 × 2,030 mm, or approximately 60 × 80 inches.

A Queen mattress is wider than a Double but narrower than a King, making it one of the most practical choices for Australian bedrooms. The measurements refer to the mattress itself, not the complete bed frame, headboard or surrounding furniture.

In simple terms, if you're shopping for an Australian Queen mattress, 153 × 203 cm is the key measurement to remember. Slight variations can occur between manufacturers, so checking the individual product specifications is always recommended.

Why Is the Queen Mattress So Popular?

The main reason Australians choose a Queen mattress is its balance between comfort and space efficiency.

A Queen gives two adults a generous sleeping surface without requiring the additional floor area of a King. It is also comfortable for a solo sleeper who enjoys having more room to move.

For many bedrooms, the Queen offers a practical middle ground. It feels substantial enough to create a luxurious bedroom focal point while still leaving room for bedside tables, wardrobes and walking areas.

The popularity of the Queen size also means there is a broad choice of mattresses, bed frames, fitted sheets, mattress protectors, quilt covers and bedroom furniture designed around its dimensions.

Standard Dimensions of Queen Size Mattress in Australia

Width

The standard Australian Queen mattress is approximately 153 cm wide.

This is around 15 cm wider than a typical Australian Double mattress, which is approximately 138 cm wide.

Length

A Queen mattress is approximately 203 cm long.

This gives it the same general length as an Australian King mattress, although the King is approximately 30 cm wider.

Thickness

There is no single standard thickness for every Queen mattress.

Mattress height can vary significantly depending on construction, materials and design. Memory foam, pocket spring, hybrid, latex and pillow-top mattresses may all have different profiles.

Thickness is particularly important when purchasing fitted sheets, mattress protectors and bed frames with specific height requirements.

Dimensions of Queen Size Mattress Compared With Other Australian Sizes

These measurements are useful Australian sizing guidelines. Individual manufacturers may have minor variations, particularly for imported products or specialised mattress ranges.

Queen vs Double Mattress

A Double mattress is approximately 138 × 188 cm, while a Queen is approximately 153 × 203 cm.

That means a Queen adds around:

• 15 cm of width
• 15 cm of length

The difference can be noticeable for couples, particularly if both people like additional room to move.

A Double can work well in compact bedrooms and guest rooms, while a Queen is often more comfortable for everyday use by two adults.

Queen vs King Mattress

A standard Australian King mattress is approximately 183 × 203 cm.

The Queen and King have the same approximate length, but the King provides an additional 30 cm of width.

Choose a Queen when you want to balance sleeping comfort with bedroom space. A King may be preferable when the bedroom is larger and you want more personal sleeping space.

How Much Room Does a Queen Mattress Need?

Knowing the dimensions of queen size mattress is only the beginning when planning a bedroom.

The mattress occupies approximately 153 × 203 cm, but you also need space for the bed frame and comfortable movement around it.

Consider room for:

• Walking beside the bed
• Bedside tables
• Wardrobe doors
• Bedroom doors
• Drawers and storage
• Cleaning
• Making the bed
• Other furniture

A room may technically fit a Queen mattress but still feel cramped once the complete bed and furniture are installed.

A room of around 3 × 3 metres is commonly used as a practical starting point for a Queen, although the ideal layout depends on the position of doors, windows, wardrobes and other furniture.

Queen Mattress Dimensions vs Bed Frame Dimensions

This is one of the most important distinctions to understand.

A Queen mattress measures approximately 153 × 203 cm.

The bed frame can be larger.

A frame may extend beyond the mattress because of:

• Side rails
• Headboards
• Footboards
• Upholstered surrounds
• Decorative details
• Storage mechanisms
• External frame construction

For this reason, always check the external dimensions of the bed frame when planning a bedroom.

If you're replacing an existing mattress but keeping the frame, also confirm that the frame's internal mattress area is compatible with the new mattress.

How to Choose Bedding for a Queen Mattress

Once you know the dimensions of queen size mattress, selecting the correct bedding becomes much easier.

Fitted Sheets

Choose fitted sheets specifically labelled for an Australian Queen mattress.

Length and width are generally designed around approximately 153 × 203 cm, but mattress depth also matters.

A particularly thick mattress or mattress topper may require extra-deep fitted sheets.

Mattress Protectors

A Queen mattress protector should match the mattress width and length while also accommodating its thickness.

Check the fitted depth before purchasing, especially if the mattress includes a thick topper.

Quilt or Doona Covers

A Queen quilt or doona cover does not have the same dimensions as the mattress.

The cover is sized for the quilt insert, which needs additional width and length to drape over the bed.

A common Australian Queen quilt cover size is approximately 210 × 210 cm, although exact dimensions vary by brand.

Benefits & Use Cases

Ideal for Couples

A Queen provides enough sleeping space for two adults while taking up less floor area than a King.

If you enjoy extra room to stretch, a Queen can offer a more generous sleeping surface.

Suitable for Master Bedrooms

Its balanced proportions work particularly well in many Australian main bedrooms.

Great for Guest Rooms

A Queen can provide comfortable accommodation for couples while keeping the room useful between visits.

Easy to Style

Queen beds offer plenty of space for layered bedding, cushions, throws and decorative bedheads.

Good Balance of Space

The Queen sits between Double and King, providing additional comfort without the larger footprint of a King.

Trends for 2025 in Australia

Layered Bedding

Queen beds provide enough surface area for layered quilts, blankets, throws and decorative cushions without overwhelming the room.

Warm Neutral Colours

Cream, oatmeal, beige, taupe and soft earthy tones remain popular for creating calm, timeless bedrooms.

Natural Textures

Linen-look fabrics, timber, woven accessories and tactile textiles bring warmth and depth to a Queen bedroom.

Statement Bedheads

Upholstered, timber and curved bedheads can give the bed a stronger visual presence.

Soft Curves

Rounded bedside tables, curved furniture and organic accessories can soften the rectangular shape of the mattress.

Hidden Storage

Storage bed frames are increasingly useful for keeping spare bedding and seasonal items organised.

Boutique-Hotel Styling

Symmetrical bedside furniture, layered bedding, soft lighting and carefully selected decorative pieces can create a refined hotel-inspired atmosphere.

Styling Advice

Start With the Bed

Let the Queen bed establish the scale of the bedroom. Avoid surrounding it with furniture that is either dramatically oversized or too small.

Layer the Bedding

Start with fitted bedding, then add the Queen quilt or doona, a coverlet or blanket and a carefully selected throw.

Add a Statement Bedhead

A substantial bedhead can visually anchor the bed and introduce texture, colour or architectural interest.

Balance the Bedside Tables

Matching bedside tables create symmetry, while slightly different pieces can create a more relaxed, collected appearance.

Choose the Right Lighting

Bedside lamps, wall lights or pendants can provide practical illumination while contributing to the overall mood.

Leave Breathing Space

Do not fill every available surface. Allowing space around the Queen bed helps the bedroom feel calmer and more spacious.

Queen Mattress Measurement and Bedroom Planning

Before buying a Queen mattress, measure the room carefully.

Mark out an area approximately 153 × 203 cm on the floor. Then add the approximate footprint of your intended bed frame.

Think about where you will place:

• Bedside tables
• Wardrobes
• Dressers
• Floor lamps
• Rugs
• Benches
• Storage furniture

Also consider the direction doors open and whether wardrobe doors or drawers will remain accessible once the bed is installed.

This simple planning step can prevent an expensive sizing mistake.
