Bed Sizes in Australia - Complete Mattress Size Guide

When it comes to sleep, size matters. The right bed size doesn’t just mean comfort — it affects your posture, sleep quality, and even how your bedroom feels. In Australia, mattress sizes follow their own standards, different from the US or UK.

This easy guide breaks down every Australian bed size, shows who each one suits best, and helps you find the perfect fit for your room, lifestyle, and budget.

Why Mattress Size Matters

Back pain, restless nights, and even relationship tension often come down to the wrong-sized bed. From solo sleepers who love to sprawl to parents sharing with kids or pets, choosing the right mattress size can make all the difference.

A properly sized bed supports your spine, gives you personal space, and keeps your room balanced — no more bumping into furniture or fighting for blanket space. Whether you’re upgrading your master suite or styling a guest room, this guide gives you clarity and confidence.

These are the most common sizes available across major Australian retailers.

Australian Bed Sizes Explained

Single Mattress (92 × 188 cm)

Best for: kids, students, or compact rooms.

Small but mighty, a single mattress fits neatly into tight spaces while offering enough room for one person. Fun fact: a solo sleeper on a single bed actually gets as much personal space as two people sharing a king!

King Single Mattress (107 × 203 cm)

Best for: growing teens, tall adults, or guest bedrooms.

Think of this as the "teen upgrade". It’s longer and wider than a single and matches the king’s length, giving you that extra legroom without taking over the room.

Double Mattress (138 × 188 cm)

Best for: solo adults or light-statured couples.

Perfect for single sleepers who love to spread out or for couples short on space. It fits well in smaller apartments or guest rooms but may feel snug for two taller adults long-term.

Queen Mattress (153 × 203 cm)

Best for: couples or solo sleepers who love space.

The queen bed is Australia’s top choice — roomy, balanced, and fits most bedrooms. It’s the sweet spot between comfort and practicality.

King Mattress (183 × 203 cm)

Best for: families, co-sleepers, or anyone craving extra space.

Generous in both width and length, the king bed is perfect for couples sharing with kids or pets. Just make sure your bedroom layout has room to breathe — ideally at least 3.6 m × 3.4 m.

Super King Mattress (203 × 203 cm)

Best for: premium comfort and big bedrooms.

Perfectly square and undeniably luxurious, the super king offers hotel-style space. It’s a favourite for families who co-sleep or those who simply want to stretch out without limits.

Key Considerations When Choosing a Mattress Size

1. Room Size: Always measure before you buy. Leave at least 60–90 cm of clearance around the bed for easy movement.
2. Body Size: Taller or broader individuals may prefer a King Single or larger for comfort.
3. Sleeping Style: Side sleepers benefit from width; back sleepers need more length.
4. Number of Sleepers: Factor in partners, pets, or little ones who may join you.
5. Futureproofing: Consider kids’ growth or moving homes.
6. Bedding Compatibility: Stick to Australian-sized sheets—international sizes rarely align perfectly.

Common Missteps to Avoid

• Buying too small just to save space or money.

• Confusing US/UK sizing when shopping online — it’s an easy but costly mix-up.

• Ignoring stairways or narrow doors during delivery (especially for king or super king).

• Skipping mattress testing — always try before you buy if you can.

According to Sleep Health Foundation Australia (2025):
