Pillow Size Guide, Standard, King & European Pillow Sizes

Standard Australian pillow sizes come in three main types: Standard (48 x 73cm), King (50 x 90cm), and European (65 x 65cm square). Standard pillows suit most single, double, and queen beds; king pillows suit king and super king beds or anyone wanting more sleeping surface; European pillows are square accent pillows used decoratively behind sleeping pillows. Matching your pillow size to your bed size and pillowcase inventory is the fastest way to avoid the "too many pillow sizes" confusion most Australian bedrooms accumulate. Below, we also cover which size category our Koala Pillow belongs to. 

Key Takeaways

• Three main pillow sizes in Australia: Standard (48 x 73cm), King (50 x 90cm), and European (65 x 65cm). Each has a specific use and matching pillowcase.

• Standard pillows suit single, double, and queen beds. King pillows suit king and super king beds. European pillows are square accent pillows used decoratively.

• Pillowcases must match pillow size exactly. Standard pillowcases won't fit king pillows, and European pillowcases are square (65 x 65cm) rather than rectangular.

• Sleep position affects pillow needs more than bed size. Side sleepers benefit from taller loft, back sleepers from medium loft, and stomach sleepers from a flatter pillow.

• A queen bed fits two standard pillows or one king pillow across. Match pillow count and size to bed width for a balanced look and shared sleeping comfort.

Pillow Sizes in Australia (cm)

Three pillow sizes cover most Australian bedrooms. Here's what each measures and what it's typically used for.

Standard Pillow

A standard pillow measures 48 x 73cm (roughly 19 x 29 inches). It's the most common pillow size in Australia and fits the widest range of beds, from single through to queen. Standard pillows are your everyday sleeping pillow, designed to support one adult's head comfortably regardless of sleep position.

Standard is the default option for buying pillows and pillowcases in bulk; sheet sets almost always include standard pillowcases rather than king or European. If you're buying pillows and aren't sure what you need, standard is the safest starting point.

Our Koala Pillow sits in the standard-size category, measuring 71 x 39cm with a 14cm loft. It's designed to fit standard pillowcases while delivering a more compact profile than a full 48 x 73cm pillow, with neck alignment support across side, back, and combination sleeping.

King Pillow

A king pillow measures 50 x 90cm (roughly 20 x 35 inches). It's noticeably longer than a standard pillow (17cm longer) and marginally taller (2cm taller), giving you more sleeping surface across the pillow.

King pillows suit king and super king beds, where a standard pillow can look small relative to the bed's width. They also work for sleepers who move around a lot at night, since the extra length gives your head somewhere to move without falling off. Two king pillows across the width of a king bed fills the space cleanly.

European Pillow

A European pillow (sometimes called a Continental pillow) measures 65 x 65cm, a square rather than a rectangle. This is a different pillow shape entirely from Standard or King, and it's used differently.

European pillows are typically decorative accent pillows placed behind your sleeping pillows during the day, or as sitting support when propped up in bed to read, work, or watch TV. They're not designed as primary sleeping pillows. Their square shape and firmer construction suit propping and back support rather than head-on-pillow overnight comfort. Two European pillows across the back of a queen or king bed is a common decorative styling in Australian bedrooms.

Standard vs King vs European Pillow Dimensions

Here's the side-by-side comparison of the three main pillow sizes, plus matching pillowcase dimensions.

Reading this comparison:

• Pillowcase dimensions match pillow dimensions exactly. A standard case won't stretch to fit a king pillow, and rectangular cases won't fit European (square) pillows.

• The three sizes serve different purposes. Standard is for sleeping; king is for sleeping with more surface; European is for propping or decoration.

• Most Australian sheet sets include standard pillowcases only. King and European pillowcases are usually sold separately.

Which Pillow Size Suits Your Bed

Choosing the right pillow size depends on two things: the bed size and how you sleep. Bed size determines how many pillows fit across; sleep position determines what pillow loft (height) suits your neck alignment.

Best Pillow Size by Bed Size (Single, Double, Queen, King)

Each Australian bed size has a natural pillow configuration that fits the width and looks balanced.

• Single bed (92 x 188cm): 1 standard pillow. Single beds are 92cm wide and a standard pillow (73cm long) fills most of the width with room to spare.

• King Single bed (107 x 203cm): 1 standard pillow. The king single is only 15cm wider than a single, so one standard pillow still works well.

• Double bed (138 x 188cm): 2 standard pillows placed side by side. Two standards laid horizontally cover the 138cm width neatly.

• Queen bed (153 x 203cm): 2 standard pillows OR 1 king pillow. Standard pairs fit the queen width; a single king pillow across gives one sleeper more surface if you sleep solo.

• King bed (183 x 203cm): 2 king pillows OR 2 standards plus 2 European accents. King bed's 183cm width benefits from the longer 90cm king pillows.

• Super King bed (204 x 204cm): 2 king pillows plus European accents. Super king's near-square dimensions benefit from the maximum-surface king pillows.

For a coordinated setup, our Queen Mattresses and King Mattresses collections pair naturally with standard or king pillow configurations.

Best Pillow Size by Sleep Position

Sleep position matters more than bed size for choosing the right pillow. Bed size determines pillow quantity; sleep position determines pillow height (loft) and firmness.

• Side Sleepers

Side sleepers benefit from a taller pillow that fills the gap between the shoulder and head, keeping the neck aligned with the spine. Loft of 10-15cm typically works. Standard or king pillows both work; king can help fill the gap for broader-shouldered sleepers.

• Back Sleepers

Back sleepers need medium loft (8-12cm) that supports the natural curve of the neck without pushing the head too far forward. A standard pillow at the right firmness usually works well.

• Stomach Sleepers

Stomach sleepers need a low-loft pillow (5-8cm) to prevent the neck from being pushed backward. Softer standard pillows work; some stomach sleepers prefer no pillow at all, or use a European pillow under the chest rather than the head.

• Combination Sleepers

Combination sleepers change positions across the night, so a medium-loft standard pillow with some adjustability suits best. Our Koala Pillow is designed to support neck alignment across positions.

• Kids and Smaller Sleepers

Kids often benefit from a smaller, thinner pillow suited to their neck size. Our Snoozytime Pillow is designed specifically for children.

Pillow Size vs Pillowcase Size, What's the Difference

Pillow size refers to the physical dimensions of the pillow itself; pillowcase size refers to the fabric case that goes over the pillow. The two should match exactly, because pillowcases have very little stretch.

Sizes match one-for-one in Australia:

• Standard pillowcase: 48 x 73cm, fits a standard pillow.

• King pillowcase: 50 x 90cm, fits a king pillow.

• European pillowcase: 65 x 65cm, fits a European (square) pillow.

Common mistakes worth avoiding:

• Buying a king pillow and assuming your standard pillowcases will fit. They won't. A king pillow is 17cm longer than a standard, and pillowcases don't stretch that far.

• Buying European pillows and using rectangular cases. European pillows are square; standard and king cases are rectangular. Different shape entirely.

• Assuming all sheet sets include king or European pillowcases. Most Australian sheet sets include standard pillowcases only. King and European cases are usually bought separately.

Slight brand variation. Some Australian brands produce pillowcases at slightly larger dimensions (typically 1-2cm larger than the pillow) to allow easier fitting. This is normal and doesn't affect fit; a "48 x 73cm" pillowcase and a "50 x 75cm" pillowcase both fit a standard pillow.

How to Choose the Right Pillow Size for You

Choosing the right pillow size comes down to five factors: bed size, sleep position, body size, existing pillowcase inventory, and how you plan to use the pillow.

1. Match Pillow Count to Bed Size

Match how many pillows you buy to the bed you have. Single and king single beds fit 1 pillow. Double and queen beds fit 2 standard pillows. King and super king beds fit 2 pillows plus optional European accents.

2. Match Pillow Loft to Sleep Position

Match pillow height (loft) to how you sleep, because loft matters more than pillow width for comfort. Side sleepers need taller loft (10-15cm); back sleepers need medium loft (8-12cm); stomach sleepers need low loft (5-8cm). A pillow that's the right size but wrong loft won't feel comfortable.

3. Consider Body Size

Broader-shouldered sleepers benefit from king-size pillows because the extra length accommodates head movement without your head falling off the edge. Smaller sleepers and children usually don't need this extra length, and a standard pillow (or the Snoozytime Pillow for kids) works well.

4. Factor in Your Pillowcase Inventory

Match your pillow purchases to the pillowcases you already own to avoid the "half my pillowcases don't fit" problem. If you already have several sets of standard pillowcases, sticking with standard pillows keeps everything compatible. If you're buying king or European pillows, budget for matching pillowcases at the same time.

5. Consider How You'll Use the Pillow

Think about whether the pillow is for sleeping only or also for sitting up in bed. Standard or king pillows are enough for sleeping. If you like reading or working propped up, adding European pillows behind gives you additional back support.

When to consider king or European in addition to standards. If you already have comfortable standard pillows and want to add more sleeping surface or decorative styling, king or European pillows are worthwhile additions. If you're starting from scratch with a new bed setup, standard pillows are the practical foundation.
