King Size Bed Size

A king size bed size refers to one of the largest standard mattress and bed frame dimensions commonly used in bedrooms, offering generous sleeping space for couples, families with co‑sleeping children or anyone wanting extra comfort. In simple terms, it’s a large bed that gives you room to stretch out, relax and enjoy luxurious sleep. The main reason Australians love a king size bed size is its combination of space and comfort — whether you’re sharing with a partner, pets or simply enjoy sprawling out, this bed size elevates everyday rest.

In Australia, a standard king size bed size typically measures 183 cm wide by 203 cm long, giving you roughly 37 000 cm² of sleeping surface. That’s more than a queen size and ideal for master bedrooms, retreats or contemporary homes where bedroom scale and comfort go hand in hand.

Types and styles of king size bed sizes available in Australia

King size beds don’t all look the same — they come in a variety of designs and styles to suit different bedrooms and lifestyles. Here’s why the options matter:

1. Standard king size bed (AUS)

This is the most common — 183 cm × 203 cm — ideal for couples and master bedrooms where space allows. It balances width and length without overwhelming the room.

2. Eastern king size bed

Similar in footprint to standard Australian king beds, but slightly more rectangular in some international markets. In Australia, the differentiation is subtle but worth knowing when comparing imported bedding.

3. Super king size bed

Larger than a standard king, often around 203 cm × 203 cm (or similar), offering extra width and length. Perfect for very tall sleepers or luxury boudoir designs.

4. King single bed

Not a true king — it’s closer to a twin size but slightly longer. This is good for tall single sleepers but not for couples.

5. Custom king size beds

Some homeowners choose bespoke bed dimensions tailored to architectural spaces or specific lifestyle needs (e.g., built‑in sleeping nooks or vaulted ceilings).

6. King bed with storage

Today’s trend blends sleeping comfort with practical storage solutions — drawers, lift‑up base systems and hidden compartments.

7. Designer king size bed frames

Statement beds with upholstered headboards, timber panelling, metal accents or sculptural bases inspire sophisticated interiors.

Across these styles, the actual mattress remains king sized, while the frame, headboard and base details reflect your décor — from minimalist modern to soft contemporary or timeless traditional.

How to choose the right king size bed size

Choosing a king size bed isn’t just about mattress dimensions — it’s about how it fits your lifestyle, bedroom scale and sleep needs. Here’s a practical, step‑by‑step guide:

1. Measure your bedroom space

Start with floor measurements — length and width — and mark out where you’d place the bed. You want at least 60–90 cm of circulation space around the bed for easy movement.

2. Consider your sleep habits

• Do you toss and turn?

• Share the bed with a partner, children or pets?
  If yes, a king size bed gives breathing room for everyone.

3. Check ceiling and window height

In rooms with low ceilings or sloping roofs, headboard height and bed scale matter just as much as width and length.

4. Match the mattress to your base

Not all king bases are equal — choose a platform, upholstered, storage or slatted base that matches your mattress type for optimal support.

5. Think about storage needs

If your bedroom lacks built‑in wardrobes or drawers, consider a king size bed with integrated storage.

6. Select a style that suits your décor

Modern minimalists lean to platform or upholstered beds with clean lines, while classic or traditional interiors might favour timber bed frames with detailing.

7. Test for comfort

If possible, lie on the mattress before purchasing — even the perfect size needs the right comfort level and support for your sleep style.

8. Coordinate accessories

Sheets, doona covers and protectors need to match your king size mattress — always double‑check measurements before buying bedding.

Benefits and use cases of a king size bed size

A king size bed does more than give you space — it transforms sleep and bedroom living. Here’s why Australians invest in this luxurious bed size:

Styling advice: how to style a king size bed beautifully

Here’s how top interior designers make king beds feel inviting and cohesive:

1. Anchor with a rug

Use a large rug that extends beyond the bed by at least 60–90 cm on each side — this adds warmth and defines the sleeping zone.

2. Layer your linens

Luxurious sheets, textured quilts and subtle patterns create depth and comfort without visual clutter.

3. Balance with bedside tables

Proportion matters — match table width to bed scale to create symmetry.

4. Add lighting

Flank your king bed with stylish bedside lamps or wall sconces from Café Lighting & Living for soft ambience.

5. Elevate with cushions and throws

A mix of sizes and textures enriches the bed’s look while inviting relaxation.

6. Choose cohesive colours

Neutral palettes with accent tones (warm terracotta, soft greys, muted blues) feel timeless and calming.

7. Personal touches

Artwork, plants and curated objects from OneWorld Collection or Gallery Home complement the bed’s presence without distraction.
