Bed Sizes in Australia - Complete Mattress Size Guide

When it comes to sleep, size matters. Choosing the right bed size isn’t just a matter of comfort—it affects your sleep quality, posture, bedroom layout, and even how well your sheets fit. In Australia, mattress sizes follow their own standards, different from the US or UK. This guide offers an expert breakdown of every bed size available in Australia, helping you find the right fit for your home and lifestyle.

Why Mattress Size Matters

Back pain, poor sleep, and partner disturbances are often linked to sleeping on the wrong-sized mattress. From restless solo sleepers to co-sleeping parents, selecting a mattress size tailored to your needs can significantly improve how you rest and recover. Whether you're furnishing a guest room or upgrading the master bedroom, this guide is your go-to for clarity and confidence.

Standard Australian Bed Sizes

These sizes represent the most commonly available options across major Australian retailers.

Australian Bed Sizes Explained

Single Mattress (92 x 188 cm)

Best for: young kids, students, or small guest rooms.

Compact and versatile, the single mattress fits neatly into tight spaces. Despite its small footprint, it offers ample room for one person to sleep comfortably. Fun fact: a solo sleeper on a single mattress gets as much personal space as two people sharing a king bed—just without the snoring.

King Single Mattress (107 x 204 cm)

Best for: growing teens, taller sleepers, or guest bedrooms.

Offering extra width and matching the length of a king, this size is ideal for future-proofing a child’s bedroom or accommodating adult guests. A solid upgrade from a single, it suits smaller rooms without sacrificing stretch space.

Double Mattress (138 x 188 cm)

Best for: solo adults or light-statured couples.

A double bed allows a solo sleeper to spread out or share the space with a partner or pet. It fits comfortably in standard bedrooms but might feel snug for two adults long-term. Popular in guest rooms and teenage bedrooms.

Queen Mattress (153 x 204 cm)

Best for: couples or single sleepers who love space.

By far the most popular mattress size in Australia, the queen hits a balance between roominess and practicality. It fits most main bedrooms, offering enough width for couples and luxury for solo sleepers.

King Mattress (183 x 204 cm)

Best for: families, co-sleepers, or luxury sleepers.

The king mattress provides extra shoulder room and leg space, making it ideal for parents sharing with kids or pets. Just ensure your bedroom has the space to accommodate its generous dimensions.

Super King Mattress (204 x 204 cm)

Best for: premium comfort, spacious master suites, or families who co-sleep.

Perfectly square, the super king is a high-end choice. It offers ample room for two adults and multiple children or pets. While it comes at a higher price point, it’s an investment in uninterrupted sleep.

Key Considerations When Choosing a Mattress Size

1. Room Size: Always measure your space before choosing. Leave at least 60–90cm clearance on each side of the bed for easy movement.

2. Body Size: Taller or broader individuals often find king single or larger mattresses more comfortable.

3. Sleeping Style: Side sleepers may need more width; back sleepers may prioritise length.

4. Number of Sleepers: Whether you're sleeping solo, with a partner, or pets makes a big difference.

5. Futureproofing: Consider kids' growth or the chance of future co-sleeping.

6. Linen Compatibility: Make sure bedding matches Australian sizes. International sizes often don’t align.

Common Missteps to Avoid

• Buying too small to save money or space can lead to poor sleep quality.

• Confusing US/UK sizing when shopping online can result in ill-fitting linen.

• Ignoring access paths like stairways or tight door frames can turn delivery into a nightmare.

• Skipping mattress testing when possible—always lie down in-store if you can.

The right bed size can transform your sleep experience. Whether you’re upgrading from a single to a queen, or investing in a super king for luxurious family comfort, understanding Australian mattress dimensions helps you shop smart and sleep well.
